Has anyone flown these planes?
The Red Hawk looks very much like the original Aerobird ( no pro mode and no X-port )
Red Hawk - $70 RTF

Spare battery is $18 for 7 cell 900 mah NiMh.
Spare tail is $5 and spare wing is $9. So if you get 2 batteries and a spare wing and tail you are up to $120. Great package if it is good stuff.

Sky Fly - $100
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKLV7&P=C
Also looks like a good value. Same spare battery and similar price for spare parts.
These are both 3 channel electrics that come with AC and DC chargers.
I had to download the video first in order to get it to work.
Look like great value packages, but how do they fly and do the fall apart after the first hard landing?
Anyone tried them?

Well, since no one answered, my nephew and I went and got the sky fly today. So far it looks good, goes together well and seems to be of good quality.

The tail goes on very easily and is self alligning. The overall set-up is very well engineered.

Ground handling is much better than I would have expected and the landing gear seems quite strong. We have not flown it yet but I think it will fly very well.

At $100 for the package it is a great value. And, you get the same battery packs that come tihe the Aerobird, but they are half the price.

The plane comes with a 6 cell pack. With that pack it balances perfectly. We purchased two additional 900 mah nimh packs for $12 each. Great price.

A spare wing was only $7 compared to the Aerobird's wing which is typically $12-$14. And the tail was about $5 instead of $10 for the Aerobird tail.

The charger is AC/DC. It takes 90 minutes to charge off AC or 60 minutes off DC. The Aerobird is DC only, but charges faster and is more flexible in that you can set the charge rate.

Overall a very very nice package.

Hopefully the weather will be nice enough tomorrow that we can provide a flight report.

Flew the Sky Fly this morning in 12-15 mph winds. It flew very well considering the conditions. I flew it from a ground take off, then climbed it to about 100-150 feet.

This one will be added to my list of recommended planes.

hmm im looking for a under $100 rtf package for my little sister. i was thinking the commander 2 or the wing dragon. this puts a kink into my thinking. perhaps with more flights you can tell us how durable it is.

I won't be getting more flights but I hope my Nephew will have a chance to fly it soon. He is a total newbie.

Noe note is that the radio range is only 500 feet. Not terrible, and probably adequate for the plane, but otehr planes in this class typically have 1500 feet or greater capacity.

If you hae a BIG flying space, you might want to consider another plane.

:p My first post .... my first forum .... hope I've got it all figured out ! I found this site looking for some info on the SkyFly .... didn't really find out as much as I might have liked, but I might be able to help somebody later .... I ordered a SkyFly the day before yesterday and it's on its way here even now !! I inherited an old nitro trainer 40 from my Dad but I've been afraid to try it out .... spent a LOT of hours with a simulator but I don't think I'm quite ready yet. There's a local club and a guy at work who has offered to buddybox with me and I'm going to take him up on that, but in the meantime I have a big field right across the street from my house that should be perfect for a parkflyer. Dead end road with no traffic so I have a built in landing strip and a big old empty farm field bordering that ... I'm expecting to see the plane possibly by week's end and I'll be sure to bring back some feedback once I get a chance to try her out !! I'll be alright as long as I don't talk about that "other plane" later on, right ? :)

Gumby Flies,

Welcome to wattflyer. And don't worry about mentioning your glow plane. Its all good and its all fun. If anyone gives you grief, send 'em to me! :D

I suggest you read the first few posts in the beginner forum. They are indicated as sticky. They are excellent information sources for new flyers. Especially read the one about 6 keys to success. They will be a big help.

As for he Sky Fly, I think you will enjoy it. Just be aware of the range of the radio. 500 feet is adequate but if you are new, it can be easy to just let the plane get too far.

I would suggest you walk the field area where you plan to fly. Get a feel for 500 feet and give yourself some reference points.

Now, this does not mean that at 501 it drops from the sky. As pilot you have to pay attention as conditions impact range. So, if the plane seems to start acting funny as it gets past a certain point, bring it back.

Don't point the antenna at the plane. The tip is a radio dead zone. The signal comes out the side of the antenna.

Your plane will get the best signal when it is flying across from you. Directly toward and directly away are the worst signal situations. So if you seem to be losing contact, turn sideways a bit so the side of the antenna is facing the plane. And turn the plane somewhat to the side to give you the broadest profile.

On most radios this will not likely be an issue. However some receivers have shorter ranges than others. If you get near the limit, they may work fine and be good well beyond, or you may start to lose signal before the suggested range. That can be a matter of weather, or battery strength or other electronic noise in the area.

Enjoy the plane. It flies very well.

Calm to 5MPH, including gusts. No more than that or you are just begging for failure!

Good luck,

Gumby flies !

I read all the "stuff for newbies" when I first found you guys ! Some really great info in there !! And then I started just spot-reading wherever I find anything interesting .... I feel pretty bad for some of the "crashes" guys .... reminds me of my very first RC plane experience .... some 20 years ago I had a Cox EZ-Bee 2-channel foam sailplane I picked up at a Toys-R-Us .... it actually flew pretty well !! It came with a Hi-Start that was a real adrenaline maker ! I had flown it for 2 years off and on when I moved up here and one day I decided to try it out downtown at the ballfield .... I had a pretty good flight, even made a pass out over the river and back .... but I was coming in pretty high and hot for my landing so I decided to pull out and make another try .... I'm watching the plane more than the flight path and I banked out and right dead center, and I mean DEAD center, between the uprights of the basketball backboard !! Sheared both wings right off clean and the fuselage just torpedoed right into the ground before I even figured out what I had hit !! :eek: Only thing worth saving was the transmitter and receiver ....

So .... an update on the SkyFly ....I got a package in the mail today from Tower Hobbies !!!! Just one problem .... all it contained was my catalog, $10 off coupon, spare 7.2v battery, and my spare prop !! The actual plane isn't supposed to get here till the 28th !! So I'm sitting here staring at a battery pack and spinning a prop in my fingers going vroom, vroom ..... but I'm not a whole lot closer to that first take-off yet !!:confused:

Gumby (vroom, VROOM) .... sheesh ! :rolleyes:

Gumby flies, what a let down. I do get a smile when I see a package at my door. The frown comes when I think (that package is too small). I open it just to see the B/O list. K

:p So the rest of my order showed up yesterday .... I had just about enough time to get it together before I had to head off to work ... doesn't really seem to be all the plane I had hoped for but only time will tell on that one ! I rushed home this morning and put a battery on charge while I double checked the manual and when it was ready I headed out to the front yard ! I taxied back and forth a couple of times and then screwed up my courage and gave her the juice ... SO QUIET !! ..... she ran further than I expected before leaving the ground but she pulled up smooth and clean and I started a long slow bank to the right .... I was probably only about a mistake and a half high (shame!) but I cut the throttle back to about half and did 2 big lazy circles of the field before bringing her back in line with the road .... lined her up and cut the throttle and she came in just as pretty as you please ! Thoroughly pleased with myself I looked her over, set her back on the runway and took her right back up again .... same thing, 2 laps and back to the runway .... dropped her a little too quickly this time and she skipped once on the landing and bounced into the longer grass at the side of the road, ending up on her nose, but barely even a mark on her, mostly dirt that wiped right off !! And then the wind started to come up a little bit, and it was blowing dead across my runway (what a surprise, right ?) so I did the smart thing and stuck her front wheel in the grass and ran out the battery ....

SO ..... two very pretty, if short, flights, and no damage done (yet) .... she looked absolutely beautiful in the air, half throttle flight with no stalling, flat and smooth .... graceful turns, although I did go very gently with those .... I've got the next three days off so if the weather cooperates (HAHAHA) I'll try to get some more noobie feedback in here !
And on a "kind of funny" note .... my neighbor noticed me out in the street and came out for a look-see .... I'm pretty sure he's on his computer right now looking at electric parkflyers !!:D Does this mean that by the end of the summer I'll be looking at combat planes ?:eek:

Got a SkyFly for one of my nephews last Friday from my favorite LHS. The owner tried to discourage us from getting that one because he had experienced "radio issues" with several of them back in December.

Glad we didn't heed his "warning" and got it. It is prettier than the rest of under $100 RTF models. Its tricycle landing gear makes it look "distinguished" and affords better ground control than tail draggers. Having a "normal" tail really makes a difference in looks as well as performance.

We are very happy with the purchase and the boy is having a ball with it (so is his daddy). Definitely worth the extra $30 difference between it and the V tail types available there at the time.

I have a notion that the perceived radio problems some experienced in December were caused by flying it beyond its specified range. 500' straight up can be surpassed rather quickly. :eek:

Gumby flies !
03-29-2006, 08:45 PM
I almost bought the V-tail one .... I was mostly thinking cheap fun and $30 less was tempting, but I didn't like the radio with the throttle slide on the back, all my sim time was with two sticks, and I really liked the trike landing gear, too ! She does look pretty good stuck up there in the blue .... and that first landing was a real thing of beauty !! Probably a good deal of luck involved there though, she didn't even bounce !

I'll try to keep a running commentary going if I have anything worth putting in here .... so far I'm pretty happy with it too !!

Am I starting to sound like I might be a flyer yet ? :D

I maidened it on "expert", switched to beginner so that my nephew and his daddy could get the hang of it fro a few flights.

Nephew learned rather quickly, so he was allowed to fly it "expert" on the second outing. Amazing how quickly he got the hang of it, though to be honest I must confess he's been messing around with electric cars for a spell. So when the model is coming toward him he doesn't get disoriented.

Can't say that for his old man, though. :eek:

Gumby flies !
03-30-2006, 03:12 PM
I made both of my flights on beginner .... this IS my first powered R/C plane ! But I think I probably could fly it on expert .... I was fiddling with it, learning how everything works, and I noticed that it doesn't kick in with the elevator until you have the rudder stick pushed almost all the way to the stops .... which is something I try to avoid ! Plus I learned to add a touch of "up" in my turns with a simulator so my thumb pretty much already pulls back a smidge when I start a turn ....

I'll probably leave it on beginner for a little while anyways ....

Gumby flies !
03-30-2006, 04:25 PM
Well ..... I slept in nice and late this morning but I WON'T be doing that again tomorrow !! I only had time for 2 flights before the wind started to come up again .... the first flight I did 2 big circles and then graduated to a figure 8 and the second flight I was working on my second figure 8 when I noticed it was getting a little harder to keep her smooth .... both flights ended with fairly bumpy but still upright landings on the grass ... landing gear looks fine once I picked the dirt and grass lumps out of it ! So maybe 3-4 minutes in the air and then I called it a day and ran out the battery ... no "ONE MORE FLIGHT" for me (yet) It ran for another 16 minutes at half throttle with a couple of full throttle blips !! So I would guess maybe as much as 15 minute flight time ? ( I got a private message asking about battery life ... ) And charge time of about an hour ... so with my 2 batteries I'm going to have plenty of time to sit down for a couple of minutes between flights ! That must mean I need another battery !! :D

I'm settin' the alarm clock tomorrow !!
Anyone know what time "old man wind" gets up ? :p

qban_flyer
03-30-2006, 05:33 PM
Just take it one step at a time Gumby.

Stick with the beginner setting until you are truly familiar with the model and flying it becomes second nature. Once you reach that stage you can move to the expert setting. :)

It's easier to fly it in breezier conditons while on expert as it affords you more control over the plane. :D Expert also makes it more responsive and less forgiving. :eek: This is where fatal mistakes "usually" happen. :p

i had a sky fly.. it is dead now.. was simple..but hated the cheap crappy fishing line controls and hokey servos. It couldnt handle any breeze and the transmitter range was terrible. I just bought a blade cp.. lets see how long before i trash that too... lol

That Sky Fly looks pretty cool! That would be a fun fart around plane for me.

03-31-2006, 03:06 PM
I wasn't too sure about those "fishing line and rubber band" controls either when I first put it together but I'm willing to give them a chance .... so far they seem to be OK .... This is my first powered plane so I don't have anything to compare it to ... but I LIKE it so far ! I want to get some time in the air before I try flying in any kind of wind .... I don't really know what to expect of the thing even in calm air this early !

"It is dead now" you said .... did it suffer a fatal "death spiral" or something or was it problems with the electronics ?

qban_flyer
03-31-2006, 03:13 PM
Most models of the V tail type have used the "fishing line and rubber band" arrangement very successfully for over three and one half years now. The Firebirds are but one example of an inexpensive model using that type of surface control.

I wish I'd had that type of control when I began flying R/C. In those days it was rubber band wound escapements and or galloping ghost actuators.

BTW, they cost a small fortune back then and were extremely unreliable at best. :o

I have taken my Sky Fly out now for 5 flights. The first 3 went surprisingly well with smooth landings! 4th flight not so good, ran out of battery mid turn and it came down pretty fast, broke the 2 out of 3 elevator tabs but 4 strips of tape later and it was in the air again. This is a great starter plane!

I think I am already hooked on this hobby, been into RC cars/trucks for about 22 years and RC Planes is a very exciting new hobby! I am already looking at getting a DX6 radio to fit with my next plane. I am not sure what that is yet because I need more time on the Sky Fly. Gonna have to hide all the receipts from my Wife!

AEAJR
04-04-2006, 11:57 AM
If you are going to get a DX6 ( very cool BTW ) these would be good next step planes.

FOUR CHANNEL AILERON TRAINERS
These planes introduce the full set of flight controls consisting of
ailerons/elevator/rudder/throttle. They are a logical next step for the
pilot who wants to take their flying skills to full 4 channel control. All
of
these planes can perform aerobatics, but are primarily designed as 4 channel
trainers with high wing designs . This makes them easier to fly but less
aerobatic than the mid or low wing planes. ARF & Kits as well as receiver ready planes with servos installed.

Magpie - with both wing kits - $55
Easy to build Foam kit -
Has trainer wing AND aileron sport wing
Master the first, then advance to the second.
They offer a complete package with both wings and all the electronics for
$160

Ed, Thank you very much for the info. I was thinking about the Tiger Moth as it is readily available here at my LHS. Do you know if it is capable of handling a brushless motor & lipo's?

AEAJR
04-04-2006, 06:50 PM
Absolutely! TM400 is on my list of future planes. I think it is just so cool looking and with full ailerons it looks great in the air.

I would try it with the stock set-up first. Certainly go Lipo if you want. It will fly better and longer at the lighter weight typically.

If you flying on a windy day, the plane will handle better if it is a bit heavier so don't hesitate to put some NiMh packs in it too. Either that or add weight to the plane right over the CG. This is called ballasting. Glider pilots do this all the time.

Ballasting will work with any plane. Even the Sky Fly will fly better in the wind if you weight it up a bit. Try it! You'll Like it!

Next time the plane is being tossed around by too much wind, say 10 mph, and you still want to fly, tape a couple of 1 ounce washers to the plane right at the CG so you don't mess up the balance. Tape 'em on with packing tape, one on each side, or on the bottom. You can try them under the rubberbands on top of the wing to, but that will shift the blance up and might cause the plane to roll more. We are doing this to make it more stable so we want the weight below the wing.

Now fly the plane. It will settle down a bit and the wind will not toss it as much, but you will have to keep the speed up a bit and it will land a little faster.

2 oz, it about 12% of the plane's weight. 3.5 ounces would be 20% of the Sky Fly's weight. I would probably not take it up more than 3.5 oz or you might stress the wing too much.

If that works well, you can now stretch your flight envelope into more wind.

See what you can learn hanging out on the forums?

Well it sounds like other people are liking the SkyFly so far too !! I've been grounded by work and/or wind for over a week now and what makes it worse is walking out through the basement every day and seeing my SkyFly sitting there on the pool table begging me to take her back outside ! But here's a quick question: I had both of my Ni/Mh packs fully charged and ready for some serious fun time back about a week ago when the wind started up and I haven't touched them since ..... do I need to discharge them before I "top them off" with my peak charger ? I've heard that Ni/Mh batteries don't have a "memory" and "topping off" doesn't hurt them but each one has only been cycled twice so far ....:confused:

I'm hoping for a better morning Wednesday when I get home from work so I can get back into the air again ... I caught myself the other day scoping out other places in town that might be good flying fields when the wind is blowing up on top of my mountain !! There's an awfully nice looking ballfield on the other side of town ! I haven't heard from my neighbor yet .... as soon as he saw me with my plane he went and bid on one on E-Bay .... :D

... :D

No need to discharge. Just charge 'em up. I usually do the first charge before a day of flying at a little lower rate than normal. For example, my ABC batterise are recommended to be charged at 1.2 amps for a 900 mah pack. The first charge I do at 1 amp. Seems to get a better charge and gets the day off right. The rest of the day I charge at 1.2 amps.

Hey Gumby, I'm in the same boat as you. I had 3 battery packs charged up and ready to go for Sunday morning but the wind came up by the time I got to the football field. Darn it :(. Just like AEJR said, just top them off with the supplied charger, it doesn't take that long to top them off and then you will be ready to go again. Last night was a good night to fly, but I couldn't get away from my meeting in time. On a side note, I just bought a Spektrum DX6 and my LHS threw in a free Tensor 4D!! Probably not a good 2nd plane so I will not build it until I get my Tiger Moth or Slow Stick. My birthday is coming up soon & I already dropped some big hints to my wife ;)

Well ..... I'm hoping for tomorrow morning ! This morning was perfect, sunny and about 50 with NO wind, but I'm working 12 hour nights and I knew if I headed out there I wouldn't get back inside with enough sack time to face tonight ! I didn't want to leave a pack on the charger unattended so I'll have to give 'em a quick shot in the morning when I get home .... but what are the odds of having two beautiful mornings in a row ? :eek:
No matter ..... at 8:00 A.M. I'll be done with the work thing till Sunday night so I figure I ought to get at least one good session in there someplace !
Speaking of odds .... if my neighbor does get a plane, what do you suppose the odds are that he'll have the same radio frequency I do ? Allowing for Murphy's Law and all .....:p

And I have to drive past a Target, a Toys R Us AND a Walmart on the way home !! I wonder if they have any on the shelves ?

Well finally a day where I could go flying. No wind, beautiful morning.... Well, got the Sky Fly up to cruising altitude and adjusted the trims, about 30 seconds into my flight.....decided to see if this thing could do a loop...got some altitude and went into a dive, got to about 50 feet and pulled back and then the wing folded!!!:eek: I had the presence of mind to cut the throttle as I watched it nose dive into the ground. When I reached the plane, it was augered into the ground pretty good. I landed in some soft mud!! I think that probably saved the fuse & electronics. The wing was torn in two and it hit the prop as their was a cut in it as well. I think that the crash from my third flight affected the 6th flight! This was the first time I was doing anything that would put some real stress on the wing and wow, how exciting was that! I am glad no one was around when I did my walk of shame to my broke plane:o

Very intuitive of you to recognize that a bad landing you had on the third flight might have compromised the wing resulting in the fold on the 6th flight. After a while you learn to check all parts after any bad landings to look for hidden damage. This is why I always tell new flyers to buy a spare wing and H Stab for the Sky Fly. It will happen during you training so you might as well be ready for it. Thank goodness you cut the power and hit soft ground.

Thanks goodness you were not flying a balsa plane. :D

FIXING WINGS AND TAILS

Repairing a creased or folded wing with packing tape alone doesn't really
work very well. It works better on the tail because it encounters different
forces, but
what I am about to explain works MUCH better on both the wing and tail and
is easy to do. It should also apply to the Xtreme, Sky Fly, the Firebirds,
and
all similar planes that use a foam core wing.

A creased taped wing might fly, but at the first real stress, its going to
fold and you are going to crash. Tape alone has no body or stiffness of its
own to
resist a fold since the wing's internal foam is compressed. Net Net, there
is nothing to resist the next fold. You need to stiffen and support the
wing. Here are things I have used for wings and the V tail with pretty good
results.

Take a hobby knife or razor blade and open the vinyl covering at the crease
or stressed area. Get the wing set in the proper position, even bend it
slightly the other way to open up the gap.

Basic repair

Fill the folded area with Elmer's white glue or titebond yellow glue. The
white and yellow glues will seep into the foam and bond with it and stiffen
it.

It is best if you let it dry overnight, but give it at least 3 hours to seep
into the foam. Now, fill it again. The second coat will fill the gap. Let
it dry 24 hours then check it. If it is fully dried, apply a little clear
packing tape to help it resist pulling open.

Stronger repair approaches

If your repair is in the center area of the wing, say within 6 inches of
where the rubber bands cross, or if you tend to fly hard, do lots of loops,
fly in wind and the like, then you probably want to take this next step.

For a wing, I add thin but somewhat stiff strip of 1/32 ply, to the top of
the wing to bridge and support the area. Typically this is 8-16 inches
long and 1/2-1 inch wide. Regardless of where the repair is, you always
center this wood strip on the wing so that the wing is balanced and the
impact on the air foil is uniform. This will resist flexing in both
directions but is not so stiff that it encourages the wing to fold at the
end of the ply. Also 1/32 ply is light and flexible so it will shape to the
curve of the wing so as to minimize the extra drag the repair will cause.
To get it to more closely align with the wing I use thin double sided carpet
tape on the strip. Try to get the ply in complete contact with the wing.
It is stiff enough to resist the next fold, but will still flex with the
wing. When it is set, cover it with clear packing tape. Don't tuck it in
tight around the ply, stretch it out so that it forms a smooth air flow
surface.

Another method to support a deep fold or a break is to slit the vinyl along
the length of the wing and embed a spar, a piece of wood or wood dowel, that
will act as a support. If you look at the T-Hawk, or the Aerobird Xtreme,
you will see an embedded dowel that provides some stiffness to the wing.
Again, glue this in using the procedure above, then close the gap with
packing tape.

If you are fixing a tail, use the same process, but use 1/64 ply or a
thinner towel to keep it light. Be sure to do the left and right the same
to keep the tail balanced. Now cover it with clear packing tape stretched
so that it forms a smooth finish with no sharp edges so the air can flow
nicely over the wing. The repair does effect the shape of the wing so it
does impact how the plane flies, but not enough to matter if you fly under
power most of the time. If you like to glide and thermal, I find these
wings are not as good as a new wing but they are very useable.

When repairing the tail, any added weight on the tail will make the plane
tail heavy. If you are flying with the 6 cell battery and tend to leave the
landing gear off, this could tend to make the plane a bit "twitchy" or
sensitive. Some people like this because it becomes very responsive.
However if you like your plane stable, you might have to add a dime to the
battery area to rebalance it. Fly it and see what you need.

I have never had one of these fold.

While Epoxy is strong, it doesn't move with the foam the way Elmer's or
Titebond will. I have seen a tendency for epoxy to pull away from the foam
as the wing flexes. However give it a try and let us know your experience.
.

Reinforcing new wings

If you look at the T-Hawk or the Aerobird Xtreme, they have a support rod
embedded into it when you buy it. This gives you a stiffer wing which will
resist bending under pressure of aerobatics. You can follow the procedure
outlined above for repairs, but you can do this when you get he wing new.

Don't Depend on Tape

Give it a try. The key message here is don't depend on tape to keep the
crease from folding again. Tape is good for closing up damage on the front
or
rear edges of the wing and for reinforcement of a new wing by the prop area,
but it can't keep a creased wing from folding up again.

I ordered a spare wing when I bought my SkyFly .... I just figured I'd end up needing one sooner or later and figgered I'd save on the shipping costs if I got it all together !

But the way it's going I may not get the chance to break my first wing !! Kinda breezy again this morning so I chickened out of trying the SkyFly again .... my neighbor got his yesterday though so we should be able to get 'em both in the air if the weather ever calms down ... maybe we should try the ballfield down in the valley ? Might be less breezy down there .... turns out he has an electric heli, too ... he hasn't successfully flown it yet, and I had it on my workbench last night putting in a bunch of new parts for him .... looks like it's ready to try again .... I think I'm going to just sit back and watch him fly(crash) that one ! I had some helis on my computer simulator and I just couldn't get anywhere near comfortable with them !

On the upside ... my hangar now includes 2 Aero Aces (and the neighbor has one) and I spent a wonderful 3 hours this morning flying them even with the wind !! I did have to climb up on the roof a total of 6 times but what the heck, once the ladder was up it was easy enough ! My girlfriend and her son both took to the air as well and both of them flew pretty well especially considering they had never operated any kind of RC at all !! "Dogfighting" them is a riot, but pretty much a hopeless task ....

I should buy a bunch of them and then set up over in the mall with one of those carts .... I bet I could sell 'em at $50 as fast as I could get people to try 'em !!:rolleyes:

Ed, question on the wing repair. My wing is broken right off. Do I use the Elmer's glue on the repair? or CA? and I have purchased some 1/32 ply. Do I use only a 1.5 inch wide piece over the break from the leading edge to the rear? Do I put one on the other wing too to make it match? Thanks in advance.

AEAJR
04-22-2006, 12:27 AM
If you use CA it must be Foam safe CA. Regular CA eats most foams.

Where is the wing broken? In the center?

Allign it and see if you can get it straight. You can use a good wing as an aid to aligning the bad one. Cover it with wax paper so you don't get glue on the good wing.

Now, see if you can get a few toothpicks to span the gap? They will be splints across the crack.

Remove the toothpicks and put plenty of glue on the halves holding the open pieces facing up. Insert the toothpicks. This will insure glue all the way down the toothpick and into the holes.

Let the glue soak in for about 15 minutes. Now apply glue again and join the two halves getting perfect allignment and making sure the wing is square and the tooth picks are not preventing the wing from aligning. Use that good wing as a base and a guide. You can even tape the repaired wing to the good wing. Use a couple of pieces of tape to hold the two halves together and to the good wing for alignment and position. Let it sit 24 hours to fully dry.

Pick it up and look it over. Be sure the glue is fully dried. If not, give it another 4-8 hours.

If it looks well aligned, put a piece of packing tape along the crack all the way around. This will help it stay joined.

Now take your 1/32 wood and cut a piece about 1" wide and long enough to span the break at least 3 inches on each side. This is to help the wing and the joint resist bending along the crack repair.

Tape the wood on with clear packing tape but don't tuck it tight around the wood. Create a smooth surface along the wing.

The alternative is to embed a dowel or carbon rod into the wing by slitting open the covering, fill it with glue then pressing the rod into the gap so that it is fully encased in the wing. Let it dry, then tape it over with packing tape.

Works for me. :D

Not sure what you are doing, but let me take a shot.

Get a piece of thin wire. I use wire fising leader. pass the wire through the fuselage to where you want to start the fising line or antenna. Use a drop of CA to glue one of them to the tip of the wire. Give it time to set, then pull it through. Remove it and go back for the next one. :D

Casey

If it pulls to the left on the ground, most likely your landing gear is not straight, or your rudder is way out of allignment.

If it pulls to the left when you first leave the ground you may be applying too much elevator, causing a stall, or applying elevator too soon, before the plane picks up enough speed to fly.
The plane should lift on its own, or require only a tiny bit of elevator, but only after it picks up speed on the ground, like a full scale airplane.

If you are getting into the air clean and then going left, you may have a balance problem or you are applying too much up elevator causing a stall. Or you may be trying to turn too sharply, applying too much rudder and putting the plane into a stall or spin.

I think you are lifting too soon, not giving the plane time to gain speed, then applying too much up elevator. That would be the usual for a new pilot. Think full scale plane and give it a longer run on the ground.

AEAJR
04-27-2006, 10:30 PM
I mentioned stall in my previous post. If you are new to flying you may not know about stall. This is excerpted from an article I wrote for RCEzine.

"Every plane has a minimum air speed it must maintain in order to stay in the air. Below that speed the wing does not generate enough lift to hold the plane. We say the wing has stalled. Stall speed can be affected by the shape of the wing, the weight of the plane and other factors. However here we are going to look at it in terms of air speed and the angle of attach of the wing, particularly at the time of landing."


This is just as critical on take off where you have to reach a certain speed in order for the plane to lift and for the wings to carry it into the air.



"Since we don’t have an airspeed indicator on most of our model planes we have to judge if the plane’s air speed is great enough through experience and judgment. We watch how it behaves and we respond accordingly. Over time we can predict when the wing will stall. In a landing situation, we can use this to our advantage, or we can be caught by surprise and pick up the pieces as payment for our inattention.

What makes this even more “interesting” is that the stall speed varies according to the angle of the wings as they meet the approaching air. This angle is called the angle of attack. The steeper the angle of attack the higher the stall speed.


A second effect of increasing the angle of attack of the wing is that it increases drag, or resistance to the forward motion of the wing. In part that is how we turn the plane, by selectively inducing drag. Drag from the tail will yaw the plane left or right. Drag from the elevator will pitch the nose up or down. Drag from the ailerons will roll the plane left or right.


If we increase the drag on the plane it will slow down for a given power setting. So angle of attack has two effects in relation to stall. We find that the greater the angle, the higher the stall speed, and the greater the angle the greater the drag. The effect of this increased drag is to make it harder for the plane to stay above the stall speed."



So, as you prepare for take-off from the ground, if your plane has not reached a high enough speed and you pull hard on the elevator, you increase the angle of attack, increasing drag, slowing the plane down and causing the wing to stall. Many planes will fall to one side or the other when they stall. So your "falling to the left" may be a result of you stalling the wing.

If you are hand launching, then visit this thread for help with hand launhcing:

Well I finally got a nice still morning the other day so I took the Skyfly down to the local soccer/ballfield to have at it again .... I checked her out and everything looked good so I set her down on the baseball diamond and throttled up ! A nice clean ROG but it took pretty much the whole infield to get clear of the ground !! From home plate to second base and the wheels just grazed the grass of the outfield as I was lifting clear ! I'll bet Caseyheer's problem is probably just the landing gear... mine taxied nice and straight (and left the coolest tricycle wheel tracks in the stonedust) ... I had to tweak my nosewheel after the last deep grass landing .... a nice lazy banking climb to the left but when I let the stick center she wanted to go right (badly) so I brought her back in and made a little adjustment to the rudder knob then sent her back up .... same climb, and better straight flight, but she seemed to want some "up" elevator so I brought her back for another tune-up .... I think my little adjusting knobs slip ? Anyone having this problem ? Maybe a couple of the little rubber bands from my daughter's braces will solve this problem ... :rolleyes: .... So, another pretty ROG (3 for 3 !) and I'm flying pretty sweet around the field .... 3rd lap around and she starts to head out towards the trees at the far side !:eek: (I wonder if my adjustments might have slipped ?) So I cut the power to keep her as low as possible when she goes in .... glides in slow and pretty about 8 feet up and tumbles to the ground ....No sweat !! I do my "walk of shame" out to pick her up and when I get out there I discover there's a small creek running along that edge of the field that's about 4 inches wider than my wingspan and 2 inches deeper than my cockpit and I'm floating right up to the wings dead center in it !! I fished her out and turned off the juice and poured her out before I took her back to the truck ..... would have been the end of my day except I had my trusty AeroAce with me, too !! Flew the battery out on that and headed home to try to dry out the Skyfly .... I just left her on the bench with the cockpit open till the next day before I tried hooking the battery back up .... everything seems to function just fine on the bench !! I was afraid I might have done the electronics some hurt because they were alive (throttle was off and right stick was centered, but still alive !) when they went in the drink .... but it looks like I may have lucked out !!:)
My neighbor got his Skyfly together and into the air the other day, too ! He did a couple of hand launches in a big pasture up the road a bit and got her trimmed and flying .... says he did about 2-3 laps each flight .... and then the day before my Skfly went amphibian he decided to fly right here across the street. He says he did about 7 laps around the cowfield across the street before he got a little too high and a breeze caught him .... pushed him out into the trees at the far side of the field and that's where the poor thing is still hanging about 30 feet up !!:eek: We'll get her back though .... he says he did his first ROG that flight and it was flying beautifully (and he's a newbie, too) right up till the tree reached out and grabbed him !!
He has a Kyosho electric heli too and I managed to get that put back together for him the other night (apparently he hasn't been very successful at flying that one yet !:p ) and I'm pretty sure it's ready to go ... I played with it a little and trimmed it out .... I had it about 1/2 inch off the ground without it wandering all over the place so I think it's close, but I don't want to be the one to try that one out !! Helis glide like rocks and the parts are dear !! I'll happily stand (behind him) and watch him try to fly it and I'll even keep putting it back together for him, but I don't think I want to be the guy that tries to land it sideways !!
So now it's back to work for a couple of days .... 12 hour shifts mean no time to fly :mad: but I'll be back out there as soon as I can ..... and I'll have some kind of a fix for that control line slipping problem in place, too !!

Key item. Rinse out your electroncis with clean water. Use distilled water for the last wash. That stream water probably has natural mineral content and could have left a ton of ti on the board which could eventually eat up the circuts.

I then rinse it all with 90% isopropyl alcohol, rubbing alcohol, as this tends to draw out water, then you set a hair dryer on cool and let it blow through the plane for a while. Then air dry it, as you did.

Watch teh battery for any signs of corrosion. on my one dip in the salt water of the ocean, after doing what I outlined here, I had to replace the battery as I got all kinds of corrosion on the connection between the cells.

The other electroncis came up fine. It wan't a sky fly, but iit was salt water.

RANGE:

Has anyone tried to measure the actual range of the radio. Hobbico says 500 feet but I would really appreciate someone doing a ground check to see how far they can walk away from the plane, with the antenna up, and still maintain control.

You will need help for this.

Have freind put plane on ground with the SIDE of the plane facing you. Sitting on a wood table would be even better. Anything metal will affect the signal. You friend can hold it but this will effect the signal somewhat.

Now, with the anteana up and all powered up, walk away and count your paces. 20 steps/paces should be about 40-60 feet. Close enough. So 200 steps, should be 400-600 feet.

Step off 100 and check control. It is best if your friend doesn't holdind the plane, just have them watch it on teh ground . Use cell phones to talk.

See if you can get to 200 steps and still maintain control. Can you go further? Try in 50 step increments.

Hold the antenna up, don't point it at the plane as that will kill the signal.

Let us know how far you can walk from it.

Well ..... I haven't done any kind of a test to find the ACTUAL limit, but I know that my neighbor's plane was at least 500' out and using a football field's length as a "guesstimator" I'd say it was pretty damn close to 600' out and he says he still had control of it before the tree grabbed it .... he managed to get it turned around and headed back towards our side of the road but he thought he was on our side of the tree when he did .... I'll try to pace it off later in the week when I'm done with "the work thing" .... and if I can get together with him we'll try to do an actual limit test ....

SKYFLY REVIEW

This was my 1st electric after years of NITRO flying. Here's my thoughts and eventual "UPGRADES".

1st flight: Hand launched by my "co-pilot". Tried a 30% angle into a light breeze (>5mph). Light elevator and a little right rudder and the SKYFLY was up and climbing. Hard to judge altitude but the plane gets small rather quickly (thank god for laser eye surgery). Not really sure of Tx/Rx range but 500ft was a comfortable "line-of-sight". Did some figure 8's to get a feel for it's flight characteristics. Responds well to rudder and elevation input. Worried about run time on the fresh batteries I made a final approach, cut the throttle to 1/2 began my decent. During my test flight I found that the Skyfly looses quite a bit of altitude in steep banking turns. I used this to decrease altitude as I turned into the wind on final approach. Dam thing wants to fly at 1/2 throttle so I had to use the elevator to tease it down. Soft landing. I was even able to use the rudder to "steer" the skyfly on the ground (not recomended)

SKYFLY RANGE TEST...Results:

Location: VA, USA
Site: Fallow corn field approximately 500acres flat as can be!!!
Test Set-up:
Plane strapped to 6ft tall PVC platform using no metal fasterners that could alter the test. This is to help cancel ground effects on the Rx/Tx.

Using a borrowed laser transit/level & step ladder to ensure a level line of site between Rx & Tx the range is tested at 100ft intervals until failure.

Intitial interferance began around 900ft. "Twitchy" on the rudder & elevator is how my spotter described the planes reactions. At 950 ft the motor would on/off like crazy and rudder & elevator control was "humming" and did not respond to input.

The "twitch" was lost at around 850ft. Which I would call the SKYFLYS "MAX" . I should note however at that range the SKYFLY is almost impossible to see and I have 20/15 vision!!!

AEAJR
05-29-2006, 02:55 AM
Great report, so we can say that the 500 feet advised by Hobbico is conservative, based on your report. We have another at 700 feet with no problems.

So we will see what else comes in but I am starting to feel better about the range on the plane. If we say 750 feet as safe range, that is a LOT better than 500.

Thanks for the great report.

BTW, the plane lands beautiful in a full glide with no power at all. I usually kill it at 100 feet and just pattern in.

Spare battery is $18 for 7 cell 900 mah NiMh.
Spare tail is $5 and spare wing is $9. So if you get 2 batteries and a spare wing and tail you are up to $120. Great package if it is good stuff.

Sky Fly - $100
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKLV7&P=C
Also looks like a good value. Same spare battery and similar price for spare parts.
These are both 3 channel electrics that come with AC and DC chargers.
I had to download the video first in order to get it to work.
Look like great value packages, but how do they fly and do the fall apart after the first hard landing?
Anyone tried them?

I have the Redhawk and have not been particularly impressed with it from a quality control standpoint.

It was supposed to be ready to fly, but the manual instructs you to make balance adjustments if necessary. Believe me, if they are all like mine, it is necessary. Mine was nose heavy to the point of having to put two weights on the tail to balance it enough to be able to hand launch it without it falling like a rock.

The windshield (battery cover) was also attached so far off center that it would barely close and I had to remove the double stick tape and fix that. On top of that a wire broke off the motor arm switch and I now have to re-solder that as well.

Once all this is taken care of it should be an o.k. little plane, and it is nice that it comes with both a DC and AC charger, and a decent sized battery.
From the posts here it sounds like the Sky Fly might be the better option unless you know how to and are willing to make a few repairs / adjustments to the Redhawk.

Got mine and crashed it into a tree the same day.

With that said, I'd never buy one again -- and not because my first ever piloting skills are poor :P

Quality was an issue for me. There is a red "enable motor" button on the side that has itsy-bitsy thin wires. One was not connected. I had to disassemble the switch (simple) and solder it together so that the engine would run. Also, the AC charger light was supposed to go out when the battery pack was fully charged --- it didn't.

I have nothing to compare it to, but my first couple flights were ok -- with some rough landings. It moved a heck of a lot faster than I thought it would! I expected (probably incorrectly) for things to be more responsive than they were, but my best bet is that the V-tail/elevon is supposed to limit responsiveness.

Unfortunatly, its demise was met when the plane crested the treeline in our park, and the wind became stronger. The wind grabbed it and made turning virtually impossible. Hey, the instructions say "don't fly in wind". So, it's mostly my fault.

Instead of putting it into the ground (near a crowd of people... a LONG ways away from me :P) I let it fly over into the trees, where it's big bright redness still lives.

But hey, at 70 bucks --- maybe I'll find a new use for the transmitter :P

What about the rudervators ( rudder/elevator) do you find that you need to get used to as opposed to a standard tail?

I have limited flying experience with a friends planes which do not use the V-tail design. He is the one who encouraged me to by the V-tail, because that is what he trained on. I'm not sure which model he started with, but now he is flying an F-16 with a mini turbo fan jet engine. The main difference is while turning, you need to be careful with the up elevator while in a turn, or you will be heading nose down quickly. Also if you only use the "rudder imput" the turn is very awkward and appears unstable. To make a turn you really have to be nose up, else you will be going down rapidly.

I've flown or have seen flown most of the RTFs like the Red Hawk (haven't seen it yet, though).
In my experience, the Wing Dragon is the best of the darn lot! It's very docile, extremely stable, and can roll like a demon and loop from level flight when you're ready.
Not bad for a rudder-elevator foamie, and much better performance than many much more expensive aircraft.

Just bought a Red Hawk, I was looking for something to entertain my 3 1/2 year old son. I gave him one of my old radios so "we can both fly it". How can you go too wrong for ~70 bucks? BTW, I have never flown anything before, I had some nice RC cars about 18 years ago and that's the extent of my RC experience. So, I took it down to the local park on Saturday, I thought it was a little windy (8-10 mph), told my son I it was too windy. What a look of disappointment in his eyes, so I decided it was worth the risk. I made sure all the control surfaces were level and tossed it into the wind under full throttle. It took off like a rocket, up at about a 45 degree angle and at about 50 feet before I could get my right hand back on the stick. I turned it out of the wind and it immediately got pushed sideways down the field. Circled back into the wind with the with the elevator/rudder all the south to try and get it down before it got carried any farther way. It came down pretty hard, caught the left wing and tumbled. My heart was pounding as I ran over to inspect the damage. To my surprise, it was fine, only a light crease in the left wing about 6 inches from the end where it had flexed and returned to its original position. We picked it up and went home.

Today, no wind, so we gave it another try. What a differance no wind makes. Full throttle, took it up nice and smooth. Turns were very predicable. Reduced throttle to about 30% and it just hummed along. I circled the field several times, did some figure 8s. I was up for about 15 minutes and got concerned about the battery life. I simply turned off the motor and glided it to the ground. I had the stock landing gear installed because the balance was perfect out of the box and didn't want to mess it up. The landing gear, of coarse, caught the grass on landing and it flipped over, but ever so softly. No problem. I ran the throttle up again (same battery charge) on the ground, it sounded pretty strong, so up it went again. About 10 minutes more flying before I brought it down. Another soft landing.

I have never flown before, however here a few observations. This plane does not turn very sharp at all. Full throttle provides alot of lift and it will stall easily. You also really have to try to make this plane come down, easiest is to just cut the throttle. It flys slow and very predictable. I think it is a great plane for beginners as long a you have the patience to wait for a calm day.

Got a Sky Fly and flew it today for the first time in 15+ mph winds... not a good idea. Got it up off the runway twice, hit a telephone pole the first time and crashed next to the river (inches from water) on rocks the second flight. Smashed my wing to heck, dented my horizontal stab pretty bad and crushed part of the fuse... Repair time until the wind goes down. Just didn't hold it's own at all in the wind, I guess that's why they say calm winds...

Thanks Ed. I'm pretty much the guy who has to try it himself anyways even though he knows it's stupid.

I tried to fly it again today in calm. Crashed immediately, as soon as it took off it tilted to the side and did a nose dive, I had no control whatsoever. I figure that some of yesterday's damage was more extensive than I thought. So now, with a parts order over $50 for a >$100 plane, I have to replace the wing, hor. stab., fuse and landing gears.

Has anybody replaced the fuse on the Sky Fly yet? Is it difficult to transfer the motor, electronics and control wires (through the tail boom)? I'd appreciate any advice.

If you have a digital camera, send me photos.

Turn on the radio - trims centered and give me as many photos as you can. I want shots of surface aligments, the allignment of the tail boom to the body.

Shoot from nose to tail. Shoot from tail to nose. Side shots.

Give me a shot of a right stick, left stick, stick forward and stick back and be sure you tell me which photo is which.

Very often the damage is minimal but the flyer does not know how to adjust.

I was just out with a newbie Saturday. Tried to fly his T-Hawk. Crash Crash Crash.

It turned out he had the elevator adjusted for a dive and the rudder for a right turn. We fixed that and I took it up in a 16 mph wind with no problems. Tossed all around but I made 3 flights with good landings.

Then I corrected his hand launches. He was throwing the plane up instead of level. Throwing up will usually result in no control, a drop to the side and a crash.

So, if you want my help, send me some photos.

If you are in the NYC/Northern NJ/LI area, come on out to our field and bring your plane. :) I love to have some of the forums people visit our field.

comments on photos: Note that I can only go by the angles you took in the photo. I asked that the plane be powered on and all trims centered so I will assume you did that or the shots are worthless.

Front to back - tail seems out of allignment with body.

back to front - Boom seems to be dislodged where it enters the body which would cause above problem. That can be fixed.

Elevator does not look broken, just down due to sagging boom.

Fuse from side - I see a wrinkle just behind the rear gear, about where the boom mounts into the fuse.

Fuse from other side. Mounter mount apperas to be undamaged

Full view from side - here I can really see how bad the boom is down.

Wing Tip Damage - Wing does not look damaged but tape along tip is loose causing a lot of loss of lift. Could cause a crash or tip stall. Get that off of there, or set it smooth and tight. You are killing your plane with that.

Under Wing Crease - you can't fly with that, it will fold for sure! I can tell you how ot repair it but get a new wing!

Overall, the damage to the fuse is not too bad. The nose is bent - We fix that with a hair dryer.

The Boom apperas to be be dislodged. That is probably easy to fix too.

All your surfaces are way out of adjustment. If the boom were straight,then all you would need to do is adjust the tail,but with the boom down like that, it won't matter.

I have fixed MUCH WORSE than this.

I can't tell if the electroncis board is solidly mounted or if it is loose. If it is loose you have to remount it with screws or glue.

FIXING WINGS AND TAILS

Repairing a creased or folded wing with packing tape alone doesn't really
work very well. It works better on the tail because it encounters different
forces, but what I am about to explain works MUCH better on both the wing
and tail and
is easy to do. It should also apply to the Xtreme, Sky Fly, the Firebirds,
and all similar planes that use a foam core wing.

A creased taped wing might fly, but at the first real stress, its going to
fold and you are going to crash. Tape alone has no body or stiffness of its
own to resist a fold since the wing's internal foam is compressed. Net Net,
there
is nothing to resist the next fold. You need to stiffen and support the
wing. Here are things I have used for wings and the V tail with pretty good
results.

Take a hobby knife or razor blade and open the vinyl covering at the crease
or stressed area. Get the wing set in the proper position, even bend it
slightly the other way to open up the gap.

Basic repair

Fill the folded area with Elmer's white glue or titebond yellow glue. The
white and yellow glues will seep into the foam and bond with it and stiffen
it.

It is best if you let it dry overnight, but give it at least 3 hours to seep
into the foam. Now, fill it again. The second coat will fill the gap. Let
it dry 24 hours then check it. If it is fully dried, apply a little clear
packing tape to help it resist pulling open.

Stronger repair approaches

If your repair is in the center area of the wing, say within 6 inches of
where the rubber bands cross, or if you tend to fly hard, do lots of loops,
fly in wind and the like, then you probably want to take this next step.

For a wing, I add thin but somewhat stiff strip of 1/32 ply, to the top of
the wing to bridge and support the area. Typically this is 8-16 inches
long and 1/2-1 inch wide. Regardless of where the repair is, you always
center this wood strip on the wing so that the wing is balanced and the
impact on the air foil is uniform. This will resist flexing in both
directions but is not so stiff that it encourages the wing to fold at the
end of the ply. Also 1/32 ply is light and flexible so it will shape to the
curve of the wing so as to minimize the extra drag the repair will cause.
To get it to more closely align with the wing I use thin double sided carpet
tape on the strip. Try to get the ply in complete contact with the wing.
It is stiff enough to resist the next fold, but will still flex with the
wing. When it is set, cover it with clear packing tape. Don't tuck it in
tight around the ply, stretch it out so that it forms a smooth air flow
surface.

Another method to support a deep fold or a break is to slit the vinyl along
the length of the wing and embed a spar, a piece of wood or wood dowel, that
will act as a support. If you look at the T-Hawk, or the Aerobird Xtreme,
you will see an embedded dowel that provides some stiffness to the wing.
Again, glue this in using the procedure above, then close the gap with
packing tape.

If you are fixing a tail, use the same process, but use 1/64 ply or a
thinner towel to keep it light. Be sure to do the left and right the same
to keep the tail balanced. Now cover it with clear packing tape stretched
so that it forms a smooth finish with no sharp edges so the air can flow
nicely over the wing. The repair does effect the shape of the wing so it
does impact how the plane flies, but not enough to matter if you fly under
power most of the time. If you like to glide and thermal, I find these
wings are not as good as a new wing but they are very useable.

When repairing the tail, any added weight on the tail will make the plane
tail heavy. If you are flying with the 6 cell battery and tend to leave the
landing gear off, this could tend to make the plane a bit "twitchy" or
sensitive. Some people like this because it becomes very responsive.
However if you like your plane stable, you might have to add a dime to the
battery area to rebalance it. Fly it and see what you need.

I have never had one of these fold.

While Epoxy is strong, it doesn't move with the foam the way Elmer's or
Titebond will. I have seen a tendency for epoxy to pull away from the foam
as the wing flexes. However give it a try and let us know your experience.
.

Reinforcing new wings

If you look at the T-Hawk or the Aerobird Xtreme, they have a support rod
embedded into it when you buy it. This gives you a stiffer wing which will
resist bending under pressure of aerobatics. You can follow the procedure
outlined above for repairs, but you can do this when you get he wing new.

This is a Recommended wing reinforcement posted by by mdp17681 for the Sky
Fly. Might work well on the aerobird too.

Don't Depend on Tape

Give it a try. The key message here is don't depend on tape to keep the
crease from folding again. Tape is good for closing up damage on the front
or
rear edges of the wing and for reinforcement of a new wing by the prop area,
but it can't keep a creased wing from folding up again.

I have an Aerobird Challenger that has been through hell, high winds, slope
soaring, thermaling, crashes, trees and more than a few smooth flights and
good landings. I would guess 250+ flights easy!!

But over time the poor bird has degraded in the quality of its flight. It
lives in my car in the original box. In the heat of the summer and the cold of
the NY winter it sits in the car, ever ready to take to the sky. It rarely
gets the kind of "tune up" that my other planes get. Tonight it got a good
going over. I share my work as it might be helpful to you.

Good old Polyethylene!

The body is polyethylene, a plastic that can be molded when it is hot. This is
the body or the pod of the plane. If your body/fuselage had become dented,
twisted and somewhat out of true, try some heat!

The nose of mine was slightly offset to the right.

I also noticed that on the last few flights I needed more and more up trim to
keep the plane flying.

It also had a dented or bashed in nose, from a hard hit.

To check the tail allignment I laid the fuse and boom on a flat board in such
a way that the two orange screws on the tail could hang off the board. I
discovered that the rear of the fuselage, where the boom comes into the body,
was slightly drooped. The boom was mounted solidly so that was not the
problem. The body was bent. What to do?

Find the heat gun!

I heated the fuselage area all around the boom, going forward half way and up
half way. I got it hot to the touch but did not melt it. The plastic becomes
more pliable when it is hot. After I heated it, I clamped the boom to the
board so that it, and the body, were flat, V tail in normal flying position,
and let the fuselage cool. Much of the bend was gone. I did it again. This
time, after the fuse cooled, all the "bow" was gone. The boom now projected
directly out from the back of the plane. The structure feels strong so I think
it will hold. I am sure it will fly better now.

The nose was dented from a hard knock. It looked bad and the indented nose
messes up the aerodynamics. I removed the nose foam and again heated the
plastic. When it was hot I took a sharpie marker and pushed the nose dent out
from the inside till the nose was smooth again. Use something rounded to do
this, not a sharp item or you might push right through.

Two problems fixed. I used some double sided tape to reset the nose foam.

Looking from nose to tail I could see that the body twisted to one side. Heat
gun again to both sides of the body. Got it hot, then twisted the body in the
opposite direction slightly past straight and held it for about a minute as
the plastic cooled. Twist was almost gone. So I repeated. Now the body is
straight and true.

So, if your Aerobird Challenger, Xtreme, Firebird whatever, T-Hawk or any of
the other polyethylene pod and boom planes, is a bit twisted, or banged in,
try a heat gun or a hair dryer. As the plastic gets hot it is more flexible
and you can undent it, or take a sag out or twist it back to true then hold it
while it cools.


Give it a try!!!

The boom between the pod an the tail - is it solidly anchored or can you
move it around inside the plane. If it moves, it has broken loose. This must
be
fixed. It will either sag causing the nose to go down or it is twisted
causing
the plane to turn right or left.

Check the tail, especially by the rigid plastic near the boom. Are there
any creases? I had a problem with my Aerobird that caused it to turn to the
right so badly that it crashed because it would go into a spiral. I tried
everything. Turned out there was a crease in the tail that caused the tail
to
flex under pressure. On launch, this could take you into the ground.


USE THE HEAT GUN to take the bend/wrinkle out of the area behind the landing gear. Then reset the boom if it is loose.

Check to see that the boom is solidly attached at the body. If this comes
loose, it can move around while the plane is flying causing all kinds of
problems. It can also twist so that the tail is no longer aligned.

If you look at where the boom is attached inside there is a pinched area. I
drilled a small hole through the top of that area and through the boom. Then
I put a 4" nylon tie through to help secure the boom. I also put packing
tape
around the boom and the back of the body where the boom exits. Between the
two, the boom is well secured.

Thanks for all the info, I hadn't noticed the tail was twisted until I read what you wrote and checked it. You're right it's twisted really bad, it is because of the wrinkle just behind the landing gear, a mounting screw popped out and the boom isn't stable.
You probably can't see in the pics but the elevator on the tail is broken. I can set it but as soon as I move it with the stick it pops out again.

Thanks alot for your help.

Clear packing tape makes a great elevator hinge.

Glad to hear my posts have helped you.

Once someone points things out to you it starts to make sense. The plane has to be straight. If you hit it hard enough to break things loose, naturally it won't fly correctly.

I wasn't born knowing these things. I joined a club and walked over to the other guys and said, how come ..... Now I pass on what 2000+ flights and the guidance of a club has taught me.

Take a shot at fixing it. Take your time and test it over high grass. Look at all the surfaces and think about what they are doing. Airplanes are all about air flow. If the air is flowing over a missaligned structure,the structure can't fly right.

Go ahead and order a new fuselage if you like, but while you are waiting, see if you can fiix this one.

good luck and let us know of your progress.

Sounds like the Red Hawk. It has very gradual controls. I saw a post on here a few weeks ago from someone who I think was exploring the possibility of drilling new holes on the control horns on the elevons to give it more throw. I doubt changing to a rod would help much as the throw would probably be about the same.

BTW, always check the little screws that hold the lines to the elevons and make sure they are tight...mine work loose often and if one ever gets loose enough during flight it will cause major problems.

Great Tip!

BTW the Red Hawk is a V tail. The surfaces are called ruddervators meaning rudder elevator.

Elevons =elevator ailerons - different type of control that is typically seen on flying wings.

If it has the little screw, like the Aerobird, you must make sure that is tight!

Is the sky Fly, I have been in RC for three years, Today I flew glow and electric planes, from a small eplane speedster pylon racer to fast sirius Hotliner, so I thing Im not an experience pilot but maybe I know a little of this, the problem is that I bought the plane for my 9 year child and my first impression was that he needs more trow, the rudder although I adjust moves a little bit, and to make a circle in the sky he needs to much time, to much right stick and it is difficult to land.

Have you considered an Airhogs AeroAce for your young pilot's first flights ?

It is small, slow, practically indestructable and capable of flying in extremely limited spaces so he can possibly get more practice in.

Yes, it is sold as a "toy" but it really is a great little plane for $30, and a great confidence builder as well. Do a google search for these and you will turn up thousands of forum posts from enthusiastic flyers. All Airhogs planes are not created equal, btw...make sure it's the AeroAce as it has a lot more control and better flight performance than some of their other models. There are a ton of simple modifications on the boards as well to make these perform even better.

When he gets bored with that I would move to something like the one of the smaller or mid size Aerobirds from HobbyZone or one of the other reputable brands. I would not suggest the Aerobird Freedom by the way...I started out with one of these and it is too much plane / speed for a beginner IMO unless he has help and a nice big place to fly it. I stuck mine in a tree at the local soccer complex on it's first flight and took a week to locate it and get it down.

One of the companies makes a plane like this that can be taken apart for parts replacement / upgrades (can't think of the brand right now) and it comes spare wing / prop / etc. This might be a better investment for a few more bucks than some of the more "disposable" ones.
A few of these also have standard Rudder / Elevator setups as opposed to the Ruddervator mentioned earlier, so they may be a little better training for a more advanced planes to follow.

Another little plane that has been a big help to me "teaching myself" to fly has been one of the little YellowBees that are sold by Harbor Freight.
These are basically twin engine pusher type thrust controlled planes, but the turn thrust and speed has several speeds...not just on/off - right / left controls. This gives much more control on turns.

I would not suggest this as a first plane though, as it can go pretty fast / high for it's size with throttle full on. It really flies best throttled down about 1/2 way once you get it up to a good altitude. This plane also has enough power to get you some elevation if you get in trouble, and has extremely long flight times with it's 4 cell AAA NIMH pack. People generally either love or hate these, so don't just take my word for it...do a little googling / reading before you buy one.

Quality control of these types of planes can be an issue, so if you get one, check it out well and return it if anything doesn't work properly. Mine flies perfectly, but I have heard of others who didn't get so lucky...if you get one of these with a defect like mis-matched motor speeds, defective turn thrust, etc. it will be practically impossible to fly.

This is just my opinion, and a lot also depends on the person learning, his natural ability & enthusiam level I suppose.

Thanks for the correction on the "Ruddervator", btw...couldn't think of what to call that thing.

Hey

I flew my Sky Fly for the first time yesterday afternoon at our local baseball park. I must say, I am very dissapointed by the response of the plane. When it's in a turn, I really have to over-control the stick to the opposite direction for seconds, before the plane respond. Does anyone else have this problem?

I also have to set the elevator by default up, else the thing just nose-dive. My first attempt to do a take-off from the ground (fine dirt, baseball pitch) - was without luck. But that was before I set the elevator up. The only problem is that now it a much more prune to stall than with a straight elevator.

Any ideas, any suggestions or experiences from anyone is welcome.

In my opinion, it is not a bad plane, but the response is just killing me. I think it would be better too if it can be upgraded with standard servo's, RX, etc.

Thanks

I think Bert we could change the nylon push rod with this thin metal pushord from the 1/2 A planes or a kind of flexible pushrod, I noticed a good movement of the servos but the transfer of the force to the Tail doesn't arrive well,,,,

Sorry, but I do not think I understand you clearly. You mention a "1/2 A planes" - what are you referring too?
And remember, (I do not know if you have seen or own a SkyFly) it does not have a servo that pushes, it only pulls the nylon string. The rubber does the work of the stiffer 'push-rod'...Please explain how you want to convert that?

Hi Bert, yes I own a skyfly, but don't know the name of this kind of servo-receptor so I called just servo, I'm studying how we could but the only thing I know is that the problem with this plane is the ineffective rudder elevator response,,,

Just a couple of quick notes from a Red Hawk owner: I bought one a few days ago to teach my 3 sons to fly (my EasyStar was starting to take a beating). The first night we put it together and found we only had one operational servo. Debated taking it back but I was pretty sure the LHS didn't have another in stock. A little investigation showed that with care you could remove the nylon plugs that hold the foam battery retainer and get into that narrow fuselage. There were the servos, the receiver, and - what's that shiny metal where the wire enters the servo connector that's plugged into the receiver? Sure enough one of the molded-in tubular metal contacts had pushed partway out of the plastic connector body. I could just get a mini screwdriver in there and lever the contact back into the connector body and over the receiver pin. Pried all 6 wires to be sure, and found another the same way though not as bad. Tried it again and all controls worked!!

We waited several days for the wind to die down. Finally got tired of waiting and took it out anyway. Winds 5-12 mph and gusty - stupid but we convinced ourselves it would be OK. Note that this is me and 3 sons age 15-20, two of them with 3 (!) flights each on the EasyStar and one complete novice, and me as the instructor with maybe a dozen flights under my belt.

The Red Hawk is a tough, decent-flying little plane. We started with hand launches into the wind, get up to 15 ft., cut the throttle and glide straight in to a landing. Then move on to an S-turn, turn back into the wind and land. It definitely got tossed around in the wind and some of the landings were pretty hard. Apart from a nick in the wing (the prop took a chunk out of it when one landing knocked it crooked) it was unharmed. After just 4 flights each the boys already wanted more control authority so we re-looped the fishing line back under the little spools. Found the same problem noted earlier on this thread: with more throw, the ruddervators can pop over center to full down and can't get back, so we put the fishing line back in its original position. Always do a complete control check after every modification, right? Then our novice's last flight went straight into a bush at speed and tore the right wing half off, so that ended the day. He was so focused on regaining control in the wind and near the ground, he never saw the bush coming! There was a light pole just beyond the bush so we were lucky really.

I fixed the wing with a brace of 3 x 1/16 x 20" balsa epoxied to the underside and wrapped with packing tape at the ends. I plan to glue some little down-travel stops to the bottom of the V-tail so we can increase the control throw again. Love the nylon bolt and ring setup posted earlier though - if my stops don't work I'll try that.

The Red Hawk seems to have some QC glitches but for $70 it's a very good buy, flies well and is tough & easy to repair. The battery gives decent flight times, too.

Just a little background: I've been (back) in this hobby for 6 weeks - something I've wanted to do after building 2 planes and flying just three times, 23 years ago. A growing family and lack of success in getting glow motors to run right put the hobby on the shelf. Then I saw a couple of guys from the neighborhood flying park flyers at the high school ballfield and figured the time had come. Now I'm flying an EasyStar - already well patched after 2 major crashes but has about a dozen flights since then. Looped it for the first time this morning before work. Pitch stability is very sensitive to both power and speed, but get used to that and it's a very nice airplane. It's a little big for the ballfield so I modded the rudder so it can turn a little tighter and fly more comfortably in limited space.

I've learned a lot from WattFlyer already, researching how to get started. Thanks guys for being out there.

Response and Control Concerns

This Sky Fly and the Red Hawk are intended to be a beginner planes being flown by people with no experience, often self training. By design they will not be very responsive as most beginners over control the plane.

I have heard this, weak response, in relation to most of the three channel parkflyers from many experienced glow and gas pilots who are accostumed to 4 channel aileron planes. They want to have the plane very responsive compared to what it is. That is not the design of the plane.

Remember you have no ailerons, so you are banking by yaw/roll coupling based on wing dihedral. VERY different from flying a plane with ailerons. By design, the plane will want to return to level flight. It will not hold a bank.

To get more throw, move the control lines down to the bottom hole, just as you would with control rods. Unthread them from the spool, feed them thorugh the bottom hole, and then rethread them. You will get more throw.

Don't be afraid to move the stick as much as is required. Who cares how much you move it as long as it moves the plane?

Do you have it on beginner or advanced setting?

arck;82616, clearly you fly very fast responsive planes. Of course you feel the plane is not responsive.

Since you want fast response, I assume you have him applying some up elevator on the turns to get faster, tighter turns. And, of course, low throttle settings will produce less air over the control surfaces giving softer response. In addition to flying parkflyers I fly gliders. Two channel R/E gliders use the same approach to yaw/roll coupled turns.

When you glide the plane, you will need more stick movement and more time to bank/turn the plane. This is normal and consistent with how all planes fly.

arck;82616, I assume you know all these things. This is more for other people who are reading this thread. However if my comments help you that is great!

I finally got some decent flying out of my poor Redhawk, but noticed that when I got it out to the outer edge of my flying area, I started to get some drop out of radio control. I know range of this plane is only 500' but I don't think it was that far away. I'm going to try it today with a fully charged set of NIMH cells instead of the alkalines and see if it is better / worse or the same. I may actually have a problem as I noticed that with the antenna down I couldn't get very much distance away at all before it started to act up. I was pretty critical of this plane when I first got it, then I over compensated by putting too much weight on the tail which really screwed things up. I have discovered that this plane just is a bit slow when hand launching it...it will fall a couple of feet but with some up elevator it climbs off and really flies quite well once it is airborne. Maybe I judged it too harshly to begin with. I will say this, it is a very tough little plane. Mine has seen several hard landings and has a couple of wing repairs and still flys well. I have a new wing for it, but was waiting to put it on until I get the bugs out and get used to the plane.

We had two Sky Flys at our field today, mine and my Nephew's. Decided to test the range. I can say we were easily out 800 feet and perhaps 1000 feet at times with no problems with reception and no noticeable glitching.

These planes were purchase 2 months apart an in different states. Based on this experience, I would say the radios have a good 1000 foot range, despite Hobbico's very conservitive 500 foot advisory.

I got a Red Hawk a couple of weeks ago, and have had a blast. $90.00 (Canadian) for everything except Tx batteries was a pretty good deal I thought.

I built some models a long time ago, but just never had time, money, or space to fly (back then it was all glow engines or sailplanes). No real experience flying to speak of. The included DVD was a nice touch I thought. I fly it over a big empty space behind the house where there is eventually going to be some church or similar larger building, but which right now is hard dirt and low weeds.

Mine balanced out of the box just where it was supposed to. I crashed it a couple of times near the beginning (which I expected). The second one was due to losing it in the sun in a turn, with the prop taking a bite out of the wing which was pushed into it. I put some tape over the cracks and had no problems since then (was actually my last crash I think).

From what I've found it really needs calm conditions to do it's best. The manual says 5mph or less to start, and it's pretty dead on. In those conditions it's perfect for me. I can control it in gusty conditions now, but it gets pushed a long ways downwind when turning if the wind comes up.

I've tried to stall it and have a difficult time doing it - it just noses over into a gentle dive. Full power puts a lot of up attitude into it, which was disconcerting, but as I fly it more I'm learning how to adjust and get it higher and higher without it being a series of ever higher stalls. I find I can do sorta wingovers if I dive, climb it with full up and then push it sideways just as it stalls. For tight turns I push it over and pull back as much as I can and it goes pretty tight. Launching is easy, just a push at full throttle into the wind and it's off.

The controls do need checking for every flight; I imagine the elastic that is countering the servo line will loosen over time, as would the screw holding the line tension, and I always check to be sure everything is level, with minor adjustments before each flight a common thing.

I haven't tested full range yet, but will try that soon. It's been a wonderful buy. Extremely tough and easy to fly. It's amazing to me how quickly everything happens when it's up, even though it seems to be going so slow.

My quibbles are that mine seems a bit underpowered. Full power will climb it, but if I reduce it beneath that it will not climb. It glides wonderfully, and I love doing slow passes overhead. Last time I 'landed' I actually caught it out of the air on the boom as I did a very slow pass. Not recommended I know but it was so slow I did it on a whim.

Now I want something with a bit more pep - a fireman near where I fly has a homemade F18 electric pusher that he flies over the same empty space when he's on - what a great plane to watch!

Just take it one step at a time Gumby.

Stick with the beginner setting until you are truly familiar with the model and flying it becomes second nature. Once you reach that stage you can move to the expert setting. :)

It's easier to fly it in breezier conditons while on expert as it affords you more control over the plane. :D Expert also makes it more responsive and less forgiving. :eek: This is where fatal mistakes "usually" happen. :p

Did you actually observe any difference in "Expert Mode" besides the lack of auto-up elevator during turns??

I assumed from all the reviews/description that "Expert" mode would have enhanced control surface throw but at least on my plane , the servo / surface movement is the same as "Beginner" mode.

My current theory is that they have artificially limited the control movement on the servos (using firmware in the transmitter) because a larger throw in Expert mode would fold the un-reinforced wings.

I also think that their advertising is misleading. Even in "expert" mode the plane is not very aerobatic.

HOBBICO RED HAWK

I finally had the opportunity to fly the RED HAWK
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKLV8&P=ML (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKLV8&P=ML)

The plane looks very similar to the HobbyZone Aerobird Challenger. It uses
the same fishing line controls and V tail system. It may even be using
similar components. I will make comparisons to the Challenger throughout my
comments.

FLYING

We were flying in a 4-6 mph wind. The Red Hawk climbed out very nicely
from a hand launch. Response was predictable but many would find the
response sluggish. However, for new pilots it is not bad as beginners tend
to over control the plane.

It is intended to be flown in under 5 mph winds and in those conditions it
should be fine. With appropriate use of up elevator in the turns you can
get good but not crisp response. This is not a "hot" aerobatic plane. It is
a low wind easy flyer that is good for self training and for cruising
around.

Overall the plane flew very well and I will be able to recommend it as a low
cost package. It is a better value, at the price, than many of the two
channel planes
typically seen at this price. Even with its mile response, the addition of
the elevator will give the plane better wind tolerance, once the pilot has
learned to control it in calm conditions.

The Aerobird Challenger has a sport mode and an expert mode. The Red Hawk's
controls operate in a manner similar to the Challenger's expert mode all the
time.
In this mode both surfaces move when given rudder commands. However I feel
the Challenger gives you more responsive handling in expert mode than the
Red Hawk. This was just a first impression, I did not fly them in sequence
to check however this seems to be reflected in posts I have read by people
who have flown both.

The plane has an excellent glide and I would expect it to thermal well. It
glides into a landing beautifully. Naturally, with the motor off the
control response is slower but that is normal.

I don't have a runway so I could not check the rise off ground take off
ability but I would expect them to be similar to the Challenger. The plane
has plenty of power but the ground control is likely to be weak so look for
a large, smooth, hard area, like a blacktop basketball court surface, for
take off. It will be challenging to take off from any kind of grass.

CONTROL SURFACES

I did not measure them but the moveable surfaces looked smaller than those
on the Challenger. A common mod on the Challenger is to extend these
surfaces to make the plane more responsive once you have mastered it. The
Challenger's servos handle this fine, but it is not clear if the Red Hawks
servos will respond with enough strength to handle this.

The pictures in the manual do not show holes below the adjustment wheel on
the control horn. On the Challenger, if you want to make the plane more
responsive you move the line to the lower hole. The Challenger manual
points this out and advises the pilot to move the lines down for stronger
response. The Challenger's servos can handle this load easily.

Since there are no lower holes on the Red Hawk, you would have to remove the
adjustment wheel and remount it in the top hole, then run the control line
through the bottom hole. This would give more throw but I can't say how
much. One of the links below shows how one owner modified the plane for
even more throw. Just be cautious about over stressing the servos. Watch
for delayed response or response that takes too long to kick in. The servos
could be working at their limit.

It is very likely that the Aerobird Challenger tail will fit the Red Hawk.

RADIO

The 27 MHz radio has a single stick that seemed to work well. The throttle
control is a lever on the back. I like the front slide on the HobbyZone
radios better as you can see the throttle position. However the rear lever
works fine once you get used to it. I have a similar control on one of my
Hitec radios.

No range recommendation is give for the radio system. I consider this a
SERIOUS flaw in the documentation. The pilot does not know what to expect
which could lead to loss of control. I would assume 500 feet and try to
keep it within that range. Over time you can try pushing out to see what
the safe range might be.

I found a similar deficiency in the Hobbico Sky Fly documentation. I own a
Sky Fly and have had it out to about 1000 feet with solid control. I have
tried this with two different Sky Flies with the same results. This may
also be the case with the Red Hawk. Just be careful.

I suggest EVERYONE send a note to productsupport@hobbico.com (productsupport@hobbico.com) and ask
about the range. If enough people hammer them on this, maybe they will fix
this documentation problem.


BATTERY and CHARGERS

I like the two chargers even though they seem to be a bit slow in the charge
rate. The Challenger charger is about 30% faster and the packs seem to
handle this higher charge rate just fine. However Hobbico spare packs are
priced about 20% lower than the HZ packs and appear to be identical to the
HZ packs. So you can afford an extra pack or two. The HZ charger, for $20,
should work with these packs and will charge them faster. The HZ charger
also works fine in the car while the engine is running. The connector is
the same.

The Hobbico manual strongly cautions against using the DC charger with the
car running. I find this a very odd and troubling note. I normally charge
packs while I
am driving. Hobbico recommends against this. This suggests a poor quality
charger, but you are paying a lot less for it too. You have to decide how
to proceed, but I dislike this restriction.

Hobbico does not offer a 7 cell option. It is possible that the speed
control can not handle 7 cells, but some brave sole may wish to give it a
try. The 7 cell HZ packs should fit.

MANUAL

Looking over the manual I find that they incorrectly refer to the surfaces
of the tail as elevons, which means elevator/ailerons. The surfaces on this
plane are ruddervators which means rudder/elevator. Other than that, the
manual seems to do a pretty good job of informing you how to assemble the
plane and fly it correctly. They do advise joining the AMA and provide
adequate caution on channel conflict.

PACKAGING

The Aerobird Challenger comes with the tail mounted, straight from the box,
which is convenient. It can also go back into the box with the tail
mounted. I like
this, but it means the Challenger box is larger. The Red Hawk requires you
to mount the tail and you have to remove it if you want to put it back in
the box. Personally I like the Aerobird Challenger approach better, but
this is a matter of personal preference.

SUMMARY

Overall, my flight impression was good, in the context of a low cost, low
wind beginner plane. I will add it to my recommended list. I dislike the
lack of a stated range and the caution about charging with the car running.
But overall I find the value of the package to be very good for the price.

There have been reports of quality control problems. Servos that don't work
and wires disconnected. Just check EVERYTHING before you fly it. If
anything seems a miss, exchange it before you crash it. Most places will
exchange a clean plane but may not be so accommodating of a dented, banged
up plane.


At 30% less than the Challenger it offers a level of value at a price. It
is less responsive than the Challenger and does not accept any of the any of
the X-port options that the Challenger offers. Take this into account when
you consider this or other RTF packages.

Nice review AEA.

Well, I don't know about all of them, but the range on mine is less than 500'.
Last time I flew it it went out of range at maybe 200 - 300 feet and wound up in a tree. I have not flown it since. I have been considering extending the antenna and trying it again.

I did the mod of moving the control adjuster as you mentioned and it does give it much better response, which is greatly needed. I got it up one afternoon in some wind and almost didn't have enough control to get it back down before doing that mod.

I also have an Aerobird Challenger, and even though it has some design weaknesses itself, I really feel it is worth the extra $40 compared to the Red Hawk. I guess the exception to that might be someone who is completely new and wants the lowest cost entry level equipment. Even in that case I'm not sure one of the 2 channel aerobirds might not be a better choice, considering it would be somewhat easier for an absolute beginner to fly without help.

I really think the redhawk has some potential for the money. Mine flew very well after the control mod, and would be an ok plane if it had decent control range. In this day and age when you can buy planes for $30 with over 1500' range, 500 ' is just unacceptable for this size plane, IMO. I agree that folks need to make the mfr. aware of this. If they would get the range up to at least 1000' they would probably have a winner in this plane.

What kind of range do you get on the RedHawk with the antenna retracted? Also, what channel is it on? (Wondering if the problem is higher probability of interference on some of the channels which might explain the variations in reported range / problems. Could also be a problem with receiver damage following a hard landing that drastically reduces the range.)

(Planning to do some range testing on my SkyFly tomorrow AM before I do any more flying to avoid a crash / fly-away. Conflicting reports on whether the range is ~500 or ~1000'.)

Jimw1956,

If the range is so short, take it back to the store. The plane is defective.

Page 10 tells you to always perform a range check before flying. This is one of the things I try to impress on the people I teach. Before the first flight of the day, perform a range check. After any serious crash, perform a range check.

If the Red Hawk won't reach 100 feet with the antenna down, it is bad. Did you perform a range check? Does it pass?

After flying the Red Hawk and the Challenger, I agree with you that the Challenger is a better flyer. I like the Challenger charger much better and I LOVE the X-port options. At $40 more, you get what you pay for.

I look at the $70 Red Hawk compared to the HobbyZone Firebird Scout, The Hobbico Sky Zap, Metgatech X-EC, Fire Fly, Sky Vector, Cosmic, and other planes in this $50-$80 price range. The Red Hawk would be my preferred plane over these or just about any 2 channel plane.

The Firebird Commander flies very well, but only has an AC charger and is only 2 channels. It does have hte X-port so you can run bomb drops and fly air to air combat with it. But as a flyer, I would rather have the Red Hawk, even if they were the same price.

BTW, you can fly the Red Hawk as a 2 channel T/R plane. It has the same angled motor design as the HZ planes so it can be flown that way.

I think the Challenger, T-Hawk, Easy Star, Easy Glider electric are better planes at higher prices.

It is all cost/benefit, and for $69, this plane is hard to beat.

How do you rate the Hobbico SkyFly versus the Challenger.

My score card after flying both:

Challenger
++ Positive control surface movement (returns to neutral)
++ Good radio range published by manufacturer (2500')
++ XPORT options (great for kids)
+ Beginner / expert radio settings (small negative is that you can't change in-flight)
-- lousy ground handling (working on adding a steerable micro tailwheel)

SkyFly
++ Great landing gear / ground control
++ Lower cost parts including bare fuse for $12.99
++ Great looking radio transmitter - good feel - standard two stick design
+ Beginner / expert radio settings (although Expert has same control throw as beginner)
-- Mushy / limited controls requiring mods
-- Inferior radio / limited radio distance
....o no distance listed in specs / manual
....o 500' limit in email from Hobbico tech support
....o conflicting field reports on control distance

Edit: OMT


The Hobbico manual strongly cautions against using the DC charger with the
car running. I find this a very odd and troubling note. I normally charge
packs while I am driving. Hobbico recommends against this. This suggests a poor quality charger, but you are paying a lot less for it too. You have to decide how
to proceed, but I dislike this restriction.


I think the limitation about charging the battery from a running car is if you are going to attempt a set and forget timer which is a bad idea. the battery will charge a bit faster with the engine running due to the higher voltage - just keep checking temperature and stop charging when it starts getting warm indicating the battery it is fully charged. (Always a good idea periodically check battery temperature with any charger.)

At $100 for the package it is a great value. And, you get the same battery packs that come tihe the Aerobird, but they are half the price.

The plane comes with a 6 cell pack. With that pack it balances perfectly. We purchased two additional 900 mah nimh packs for $12 each. Great price.

A spare wing was only $7 compared to the Aerobird's wing which is typically $12-$14. And the tail was about $5 instead of $10 for the Aerobird tail.

Hi all,

Great forum and lots of great advice here for newbies like me.

I am the proud owner of a new Sky Fly and just figured out after the first taxiing practice that I need extra power packs.

Do you have a source for these amazingly priced battery packs? Lowest I could find on the net was 16.99. :confused:

Thanks,

12-31-2006, 02:07 PM
Typically you buy them the same place you buy the plane. 16.99 is a good price as they are exactly the same packs that are used in the Aerobird, but the aerobird packsa are $22.

You can check e-bay or other sources and look for Sky Fly, Red Hawk, or 6 cell Firebird Commander, or Aerobird packs. They should be 900-1000 MAh, 2/3 A size packs.

I would tend to agree. In beginner mode the transmitter adds a lot of up elevator even in gentle turns that can cause the plane to stall. (I found myself adding down elevator in turns to keep the plane level.)

If you change the control lines to thicker fishing line, it responds much better in Beginner and Expert modes. (The fishing lines they are using is very stretchy and produces a very mushy control response.)

Very nice looking/flying plane.

The sky fly is better for gound handling and for takeoff from the ground. It may be a bit more rugged in the body as well, but that is a matter of speculation.

Both fly well if you take the time to make sure they are properly trimmed and you wait for calm air to do your first flights.

If you go for the Red Hawk, use the $30 to get a second battery and a spare wing. ;)

If you get the Sky Fly, do the same!

cbatters
01-03-2007, 02:45 PM
I would agree.

Skyfly has a more substantial body, MUCH better landing gear, high quality transmitter with beginner/expert modes and includes both DC and AC battery chargers. I have flown both and the SkyFly would get my vote. (although Red Hawk flies very well.)

Suggested mods:

SkyFly - Replace stretchy control lines with thicker fishing line for more positive control

RedHawk - Replace tiny control horns with either SkyFly or Challenger control horns to get more positive control surface movement.

Challenger - One other option would be to go with the HobbyZone Challenger which has a beginner mode to make it as easy to fly as either the SkyFly or the RedHawk (just keep the throttle down to ~50%.) In expert mode it is much more acrobatic than either the SkyFly or the RedHawk.

Challenger requires no mods out of the box, is very rugged and supports XPORT accessories (which can be a lot of fun.)

Really stupid question maybe, but I assume there is a wheel on the tail of the Red Hawk?

As for my decision, I am leaning towards the Red Hawk simply beacuse my gut tells me that I will want a Supercub or maybe something else in the near future, after I get over the learning curve. So low cost entry in the Red Hawk and a future trainer for a couple friends, and the second plane comes later. Make sense to you guys?

Challenger is still a better plane as per earlier post and reviews from others on this site. (see my earlier post)
For about the same price as a Red hawk, the Challenger is a much better plane.

Hey, I have never flown an RC plane before but bought a Sky Fly this weekend. Other than having to go to Home Depot to buy a ladder to retrieve it from somebody's house and crashing it hard about 5-6 times (each giving a new chip into the primary wing but otherwise it's fine as long as I re-trim the fin and stabilizer after some of the crashes), I've had it in the air for a couple of minutes at a time.

First impressions are good. HOWEVER, this thing out of the box is banking hard to the left, which I am sure is a key reason I cannot keep it well airborne. Any ideas to fix this? The reason is that with the wing braced to the fuselage, its right tip is above the left when I look at it from the back of the plane with the stablizer as a horizontal reference (so it's twisted, kind of). I've used some paper towel to wedge on the left side on top of the fuselage and bring everything into alignment, but it's not a perfect solution, though it does help. Any other ideas?

Otherwise, I think this is a good plane. The fact its propeller is on the back is superb. I surely would have destroyed it by now otherwise. Its transmitter felt sturdy and I feel like the plane would not be overly hard to use for a beginner as long as its wings are properly level in relation to the stabilizer and fin at the back.

This and a picco z (or one of the knock-offs; I couldn't find a picco z but have used two knock-offs now and they fly very nicely) are a good intro into rc flight, I feel. If only I could convince my wife to let me get a proper beginner's kit for a 6 channel helicopter :)

I was flying in 5mph+ winds, btw. The instructions say don't do this unless you're experienced but if it was well-trimmed and in the hands of a good pilot I think it would realistically handle 10 mph without a major problem, but do know what you're doing first or else it will smash into somebody's roof :D

four thoughts;

1. Wind will make it harder to fly and each crash may necessitate repairs causing the planes perfomrnace to decline

2. Does the plane fly straight when you are not trying to turn (can you get it to fly straight using the rudder trim on the transmitter0

3. Does the rudder move the same amount left/right when you use the rudder stick on the transmitter

4. Pics of wings and rudder with transmitter trims centered would be helpful (obviously with battery in plane so transmitter causes surfaces to move)

The best way to describe this is imagine holding the fuselage in your left hand, palm down, and the tail in right hand, palm down. Now twist the left hand with the wrist going toward the ground, the end result being that the fuselage is not aligned with the rear of the plane, so when its wing is strapped on top, the right wing tip is high and then the plane continually banks to the left.

I managed to get it pretty well aligned on one of my flights--the one I flew for a few min, then I got confident and hit the gas a bit more and earned a new chip in the wing!

Wondering if the horizontal stabilizer is not sitting flush with the tail mount. (has been a problem in the past and required a little plastic to be trimmed)

When you get a chance, post a pic looking head on to the plane so we can see the alignment of the tail and the wing relative to the fuse.

Would not bother flying until you get this sorted out because the plane will not be stable if the wings/stabilizer are not perfectly aligned. (3-4 degrees is enough to cause horrific stability problems)

Also a good idea of hand tossing and trimming before even thinking about using the motor. If it won't glide straight ahead at low speed from a hand toss it will be a real PITA when it is flying faster with the motor.

Hey, I have to wait until the weekend to fly unfortunately because it gets dark at like noon these days. Is it possible to get cheap and minimal LED lights that can be put on a plane to fly it "safely" at night? I'd need enough so that I could fully get my bearing on its orientation in the sky obviously. I don't know if that's a stupid plan. I would not try it until i can at least fly without crashing, but after that I think it would be fun.

Night flying can be tough even for experienced pilots. Master the plane in no wind / daylight before taking on more challenges.

I own a Flyzone Red Hawk. First flight I crashed, second flight I crashed, third flight I crashed really really bad. Then I noticed the tail wing mount was not straight, making the tail wing crooked in relation to the front of the plane. I also tried to follow the instruction manual and make the tail boom parallel to the ground by gluing pennies to the tail...I was wondering why my plane wanted to porpoise in circles!!

Flyzone was nice enough to send me a new plane due to the tail wing mount being glued on crooked. First flight with my new plane was great. The wind was definitely too gusty and about 12 mph, still had fun.

I'm thinking about getting a HZ Super Cub as well....

Unusual to cause serious damage to a light plane from a hand toss without power. Very easy to destroy a plane if you get it flying faster/higher with the motor and then lose control.

OK I got the sky fly properly balanced and, I think unrelated, started hooking the wing on properly (I'd had the cockpit end go under instead of over the wing and the bands were weird the way I had the first two support bands).

In any case, I burned through a couple of charges yesterday which means that I was flying it. I can now maintain its flight indefinitely and got a loop out of it (though first I was too low at start of the loop and rammed the ground hard). The plane really does stand up to abuse well and flys quite well, too. It was gusting yesterday up to 10 mph but I had waited all week so flew it anyway and it really does handle that amount of wind quite alright. I generally fly at half throttle, which is enough for good maneuverability. The thing doesn't go more than 10 min on a charge.

So I'm very pleased that I've finally got this sorted out.

When the battery gets worn, the propeller will just stop spinning out of the blue, though one still has power on the fin and stabilizer. That is ok but I wish I could just have the prop get weaker because if it dies during a turn or above some trees or when I'm about to hit a house I can see losing the ability to do much, since power is needed for optimal control. In the future, I'd probably just be really careful if it's been out for 7+ min and not fly near houses as much. It would be good if maybe the prop would just cut off once or twice to give indication of a weak battery instead of failing, but I don't know how other planes work.

All in all, $99 very well spent. I would like to continue to master flight on this and then move up to something with ailerons.

I snapped 2/3 off the end of the antenna and still had full range within the 3-4 acre field I fly in.

Glad to hear that you had some successful flights.

1. Wing mounted on top of canopy would raise the leading edge of the wing and cause excessive lift/stalling. Might have been part of the original problem.

2. You may not get full capacity from the batteries until you run 4-5 charge/discharge cycles

3. Before the battery cuts out, you should be able to detect a reduction in power and bring it down before the motor cuts out. (Some people use a timer so they get a warning before motor cutout.) In no wind, dead stick landing is pretty easy. In higher wind, it is trickier especially if you let the model get downwind.

4. In many cases, you can get a little more motor time for landing by returning the throttle to off for a few seconds and then applying partial throttle.

5. In all cases, altitude is your friend. If the plane is high enough you have all kinds of options.

Good idea to pick up a replacement antenna to reduce the risk of crashing/losing your plane. Range will be reduced with the broken antenna and you won 't know how badly the range is reduced until you lose control.

(Now is a good time to put your Name / Phone number on the plane just in case.)

ClintYep, I will likely buy a spare one this week and possibly some more fins/wings. They're pretty badly nicked though I have to say it's still flying quite well even though one of the wings has half of its front quite chewed up and I think its being chewed up is going to continue to be partially responsible for the mild tilting-to-the-left that the plane continues to do because the right picks up more than the left.

You're right that a few seconds off allows the propeller to turn again and I think I will try and remember that next time so that if it fails I can possibly regain its use just before landing. I've yet to do a successful landing, though I've not really tried that much yet.

You would be surprised how well you can repair a wing with a few scraps of foam and some packing tape.

If you get a chance, please post a head on picture of the plane with the wing mounted so we can check the alignement of the wing and tail.

You should be able to trim the plane to fly straight with the rudder trims. If not something is wrong.

Edit: If wing / tail are not perfectly aligned, it will never be stable because correct trim will change with airspeed. As little as 2-3 degrees can make a HUGE difference.

LANDING
Great way to perfect takeoff / landing is to fly 2 or 3 circuits around the field and then bring it in for a landing. That way you get 4-5x more practice takeoff/landing per battery. The most important thing about landing is to plan the right altitude and approach for landing before you even launch the plane.

I rather enjoy the thrust vector planes. I got back into the sport when I bought a 2 channel thrust vector plane similar to the Oriole.

If you are comfortable launching the Oriole and flying it at 75-100 feet, you are ready for the Red Hawk. You will be much more successful with the Red Hawk or any plane if you get it up high enough that you can make a mistake without crashing.

1. No wind
2. Firm hand launch with no motor - trim plane for level / straight flight
3. First flights straight ahead, keep the nose down, cut power, land
4. Then launch and power up to 100' - reduce power to 50% and then gentle turns.
5. Keep speed up, nose down and stay above 50' until you are ready to land

I have to admit, my biggest challenge has been trying to land. Don't get me wrong, I do get the plane back on the ground. But, most likely its not the way you get your planes back on the ground.
I've been learning a lot from your advice that you've already given me in other threads. Trimming my planes without power has been working out really well. See whats wrong before I apply power. So, I am a little nervous about the new 3 channel planes that I'm starting to add to my hanger. I don't want to break them right off the bat.

Airhead, I own a Red Hawk and have about 3 successful flights under my belt. It's not a difficult plane to fly. Be sure to take the advice posted, and definitely keep the plane up high during flight. I crashed the first 3 flights, then I learned. Also remember, after hand launch with full throttle, and after the plane climbs up to desirable height, pull the throttle to about 50%. I forgot to do this my first flight and it kept climbing and climbing and climbing. I was freaking out!! I bet it went up 300' to 400'!!

Have fun and let us know how the first flight goes...

Six Keys to Success
http://www.wattflyer.com/forums/showthread.php?t=18

Most of the better starter RTF planes, like the Easy Star ( best of the bunch ), Red Hawk, Aerobird Challenger, T-hawk, HZ Super Cub, Sky Fly, are planes that have excellent glides. In fact I fly my Challenger with the motor off about 50% of the time and when I teach I teach gliding skills as one of the first things new pilots need to know. I do this at 100 feet. This way when you run too long and lose the motor, you won't care.

As Clint says, when you are flying, get up to about 100 feet when you are flying and stay there. Not only does it give you more room for mistakes but it gets you away from turbulance caused by air blowing over and through the trees. Once you get down to tree top height you are flying in turbulant air, which is much harder to manage.

Landing can be a glide on all of these planes. When I teach people to fly these planes I always have them land in a glide.

When you are ready to land, reduce throttle to about 1/4 or low enough that the plane willl lose altitude and circle the field. Plan your circle so that you will be able to point the nose of the plane into the wind for landing and give yourself plenty of room.

Each plane is different but this will work for all of these planes:

At 1/4 throttle, get the plane down to about 20 feet altitude

Work your circle so you are downwind about 100 feet when you hit 20 feet altitude.

Gentle turn into the wind

Level the wings and turn the motor off.

Now, all you want to do is keep the wings level and let it glide in. Just before it touches, about 1 foot off the ground, give it a tiny bit of back elevator, up, so it doesn't bump the nose.

If your plane won't glide in like this, you are out of trim.

I have thousands of flights on these kinds of planes and this is how I land all of them. How far down wind you make your final turn, and how high will be a matter of personal taste, but if you follow that procedure you can tune it over time till the plane touches right in front of you.

ClintYeah, flying low is one of the reasons i"ve crashed so much. I also found I was playing with throttle too much and it was easier when I just got the plane in the air, found its cruising speed, and basically didn't touch throttle again.

In any case, if the red hawk is as robust as the sky fly, and it probably is, it can take a few crashes!

I'll defer to Ed who I'm sure is a much better judge of actual air speed of various models.

My guess is that the SkyFly can reach 20 MPH in level flight - considerably faster in a dive. (Challenger is more like 25-30 MPH due to less drag.)

More importantly - why do you ask?

It's not big but keeps me on my toes. I'm sure a stryker could fly there but maybe not to its full potential.

A correctly trimmed 2/3/4 plane will fly itself until you tell it otherwise. 2 channel thrust vector planes will bank and lose altitude if you keep applying let/right turn for more than a second or two.

01-28-2007, 01:53 PM
The question everyone has on their minds! How much weight can a sky fly carry?

Well, the stock plane is is 474 grams including everything (battery is 120 grams of that). It's got a 7.2, 900 pack. I wanted more power. Instead of doing the "smart" thing and buying 1400-1500 2/3 A cells and getting a proper pack that way, I decided to make a pack out of AA batteries rated at 2000. Lots of juice, sure, but lots of weight! After putting the pack together, the four batteries went in the front compartment and the other two as ballast in the middle. The plane's weight was kept well balanced but it topped the scales at 550 grams.

At full throttle (which of course drains a lot of power), the plane can get airborne but is tricky to fly. Sharp turns are a no-no, so that requires a lot of space, which I don't have. A better pilot could make it work, though, but it was definitely tricky. Having two bats external also affected aerodynamics.

Picture quality is bad because I used my digicam batteries on the plane, so this is cellphone.

http://skoorbs.com/images/internal.jpg

http://skoorbs.com/images/external.jpg

BTW, 6 AAA bats rated at 900-1000 would shave about 20 grams off the stock pack but would require a little weight at the front to balance it.

On the plus, I just got the stock pack back in there and did two landings, the second of which would definitely have been a perfect landing if not for the nose-dive in the snow (it's not hard-packed), but I could see the three wheel skim marks on the snow. I'll probably turn off the beginner mode on the TX soon because I think the way it plays with the elevator may not be helping me anymore.

Airhead Don't feel too bad about the crashes. Yesterday I flew my plane through a small tree and the wing decided it didn't want to join the fuselage for the trip. The wing was in bad shape anyway, but this won't glue back together...

http://skoorbs.com/images/crash.jpg

Though I'm getting much better I also realize I need to get a lot lot better before I entertain real thoughts of flying a stryker or something similar in the small space I have, although I can tell that something that cuts the air better would work (since it's always mildly windy behind my house) and something with ailerons (if one knew how to use them properly) would probably handle the wind better. I feel like I'm getting somewhat manhandled by the wind, though it doesn't really decrease enjoyment at all. This has been a great starter plane. If it got stuck in a tree tomorrow, I'd already have gotten my money's worth.

Interested to find out what kind of run time / voltage you actually get from ordinary AA NIMH batteries. They have high MAH ratings but are not designed for 8-10A output required by a 400 class motor. (High current NIMH batteries have much lower internal resistance.) My guess is that you will get less voltage and less run time from your AA pack than you get from a stock 6/7 cell pack.

What brand AA cells were you using?

Quick check would be to measure the voltage across the motor at full throttle.

ClintI was using Rayovac IC3 "15 minute" batteries, but since the thing only ran for 15 seconds or so, I have no idea. I didn't know much about internal resistance of high-current batteries, so that's helpful. I assumed that RC batteries were just different shapes and things and not just different internal configurations.

I had no way to check voltage or watts or anything while plugged in. It would be nice to have a meter like that, though.

Hey, had my first sucessful takeoff. The road on the top of that pic served as a runway. No problems, but my Lord it's windy out there, so maybe no more flights today. Another tip: Fly upwind. I flew down and have never had the plane so far away, it probably was reaching the end of its range, and definitely the end of my eye sight. I got it to land in my backyard, though, so no worries :)

I was using Rayovac IC3 "15 minute" batteries, but since the thing only ran for 15 seconds or so, I have no idea. I didn't know much about internal resistance of high-current batteries, so that's helpful. I assumed that RC batteries were just different shapes and things and not just different internal configurations.

I had no way to check voltage or watts or anything while plugged in. It would be nice to have a meter like that, though.

You can buy a DVM (digital volt meter) for under $20 at Radio Shack or Sears. Best $20 you can spend if you are flying electics.

Glad you didn't lose it. Time to put your name on your plane if you haven't already...

Landings! Not only did I use the street (grass has 1+ feet of snow everywhere) to take off on but landed several times in a row all without issue and in one or two cases with enough leeway on either side of the plane to take off again where it landed. The first landing was actually right in front of my house and I got it on film :)

Had to abort one landing because of a minivan coming down the street. THe plane glides very well now and is perfectly balanced now that I've got a small strip of duct tape padding up the left between the wing and fuselage.

It feels good to land on the wheels and not on the wings. It was at a fairly steady 5 mph which I found helped because it made the forward speed fairly low landing into it.

Bought myself a red hawk to ease myself back into the hobby. Have flown anything from 1/2A to giant gas planes. Assy. but not yet flown the red hawk. I was hopeing to fly at a parking area near my home. Are the controls realy that slow?

As compared to the typical 1/2 A glow plane, you will find the plane slow and sluggish. No ailerons!

Having said that, the goal of the plane is to be flown by someone with no flying experience. You are not that person. To someone who has no experience it is just right.

It will not take much wind, so under 5 mph to start.

You can increase the throws by moving the control line down the control horn. I think there is one hole.

Consider this a powered glider as compared to what you have flown in the past.

Very mushy compared to Challenger - in part from smaller control surface and tiny control horns. I would suggest removing the stock control horns and replacing them with either SkyFly or Challenger control horns to provide better down control response.

If you haven't assembled/flown it yet you may want to consider a Chalenger - especially given your flying experience. Challenger can be flown as tame as the Red Hawk but is much more aerobatic.

AEAJR- Thanks for the reply. Due to illness that caused nerve damage I have had learn to learn to walk all over again. It has messed with my hands also, that's the reason for the fire hawk. Have also assysembled a GWS Slow Stick. Any advice on it?

Slow Stick is a wonderful plane, but again a slow flyer. Inital flights should be under 3 mph. This plane is so slow you can fly it indoors in a small gym.

Just follow the directions.

I am new to all this posting and stuff, but I did manage to find threads on the Slow Stick. Sounds more like what I'm looking for. New to elec. setups, going to need info on all this BEC and ESC stuff.

Going to threads on the Slow Stick for help. New to elec. planes, don't understand all this ESC and BEC stuff.

I flew one that a flying buddy has last fall when they first came out. They fly like the first version only they are a little faster and more responsive. They now have push rods for the rudder and elevator instead of the nylon line and rubber band setup on the old one.

Skyfly 2 2.4ghz Maiden!!

i finally rigged up a charger and got my battery mostly charged...couldnt wait for it to get completely charged but i still got about 10 minutes in with it at 90% most of the time.

I throttled it up and gave it a toss, needed some up elevator so i trimed it and flew around for about 2 minutes, came in for a nice landing in some rough grass, nosed over but no biggie. throttled it up again and off i was flying... alittle touch and go on take off though as i didn't toss it quite hard enough...lesson learned. came in for a little rough landing after a few more minutes and again slight nose over but sideways? lost a wheel in the grass, me and the wife looked for a few minutes but i just gave it a toss and flew around again for abit longer and had my 4th landing(missed a landing i guess) and well with the wheel missing it didn't really move on the ground much but no problems, i'm deffinately making the elevator larger, rudder response was actually pretty good, coulnd't get it too loop but i didn't try until 5 minutes in, had some ok stall turns though! hope everyone else with this plane does well, oh and by the end most of my thumb screws were loose! so make sure they are tight and of course check them after each landing(i didn't oops!!)

the only other thing that would have been great is a second battery. but it woulnd't have helped today since i just rigged the charger this morning

now to get more planes!!!!!!!!!!!!

had a couple more flights, today i got it way up above the trees finally, i had been keeping it in close and lower.

thing loves to soar!! had 10mph winds i'm guessing and i throttled it up a couple hundred feet and then cut the power to 50% and just floated around up there on the wind!! after about 10-15 minutes i came back to lower flight and the wind near the treetops (at the edge of the field) were making some interesting currents, so after about 2-3 minutes of that i brought it in. tossed it up 2 more times for short little flights to eat the battery and practice landing... worked great. my home made wheel is lacking however and some howe the carbon boom is now loose and rotates 15 or so degrees odd. i also cut the elevator out to the tips, much better response, rudder still seems ok though on the edge of too small

keep em flying!!
