Yes...'Dave' luck has set in and the cowl is damaged. I can fix it so it wont be noticed, alot easier than trying to get a new one:

http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0690.jpg


The gapless hinges are perfectly installed....I'm impressed!

http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0691.jpg

The tail section gets assembled only one way, cant screw this up!

http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0693.jpg

Make sure it gets glued on square -

Then glue square to the fuse -

Notice the flat profile type wing with a bit of undercamber to provide the slow flight -

http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0698.jpg


Although the tops of the wings provide that 'ribbed' look -

I am even impressed with their solder work on the landing gear.

http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0701.jpg


I put the wings on to see how it looks. I'm still waiting on the motor and servos to show up in the mail.

Good timing with this thread, Dave, as I just picked mine up a few days ago, and hope to start assembling it this weekend. I bought the motor, esc, and battery pack at the lhs, along with the kit, so I don't have to wait for anything other than the time for this little project. I've seen on other threads that installing the rigging is a good idea, and that the wheel hubs need some inserts to strengthen them. I'm looking forward to having an indoor model, as my past experiences with trying to fly "parkflyers" indoors have been less than satisfying. No real crashes doing that, but no real fun either, as constantly banking and yanking to keep off the walls gets a bit stressful.
Brad.

BTW, the wingspan is actually 33" at the LE, and 35" at the TE, so averages 34" at the middle. That's an inch or so more than my SE5a, but the wing loading should be less than half as much.

Hello Dave. Glad to see you are doing a build thread on this one. What motor did you decide on?

I can't keep this plane out of my head! I can just picture it floating around the cul du sac that I live on. We have frequent no-wind days here, and it would be nice to get some flights in without having to load up the car. I am definately going to get one soon.

I got my motor, servos, props, and batteries in the mail today!

I'll show you the components and give you links to where I got them.

Here is the motor, it is from Heads Up RC. A 2712-12 Outrunner (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=220151710097&ssPageName=STRK:MEWN:IT&ih=012)

I already had this ESC....its an 18 amp, way overkill. I'll see if it fits in to save me a buck.

http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0715.jpg


Here is a 9 gram servo I will be using. I also got this from Heads up RC (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=220136915898&ssPageName=STRK:MEWN:IT&ih=012)

http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0713.jpg

Also...the battery from Heads Up RC (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=220158864596&ssPageName=STRK:MEWN:IT&ih=012). Its a 2 cell 20C 500 mah Lipo -

I also went to HeadsUpRC for my power setup. I decided on the 2210-21 outrunner with a 12A ESC (http://cgi.ebay.com/2210-21-Outrunner-Brushless-Motor-12-Amp-ESC_W0QQitemZ220151708758QQihZ012QQcategoryZ34056Q QtcZphotoQQcmdZViewItem). Not quite as much power as yours, but it should do nicely. I also got servos from them (the smaller 5g ones), and the same battery and prop saver as you. About the only thing I still need is an Rx. I will probably get a Berg 4 channel.

Installing the motor.

Well......first modification. I kind of knew this was going to be needed. The black carbon tube is made especially for the eflite 250 outrunner. That motor was a bit pricey so I got a little stronger motor from Heads up. I'll walk you thru the fit -

Here is a picture of the carbon tube and the rear of the outrunner I will be using, they are the same size. The tube is supposed to fit over the shaft.

http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0722.jpg


Here is the new piece that I made, its just nylon stock I found at work and drilled out to fit the shaft.


http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0723.jpg


Here is an idea of what the black tube does to hold the eflite 250 outrunner in place (if you so determine you need that motor)

http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0725.jpg


Here is a big picture of the pieces:

I noticed the back end of this motor is a little different, the carbon tube might work or you might be able to use the base mount and secure it to the motor box.

------------------------------------------------------------------
With my motor I dont think the heat will be too much of a factor. From the specs it draws 8-9 amps max and there seems to be alot of metal to help share the heat. I have a similiar motor on a 3D foamie and it barely gets warm after 10-15 min of flight. In the manual it says you do most cruising around @ 1/2 throttle....I dunno, we'll see :)

That is the same basic system that eflite uses for the recommended 250 outrunner. They said to use RTV to secure the shaft to the tube. It feels very strong & a tight fit. The plane only weighs 8 oz and the motor pushes 12 oz of thrust (a bit overpowered, no biggie :))

So....all in all its really a small plane with a small motor. RTV can withstand temps that internal combustion engines produce & make a strong bond, so I assume it should hold.

Hi Dave,
No, I don't think they are too big. most folks will like the larger photos, I think. I have had some problem getting this thread to load. But last night my computer did something strange while it and I were asleep. this morning I had to shut it down and restart it. Had a unusual screen showing that some bad stuff had happened. It seems ok now, just loads this thread weird...

After a minor doink I broke one of my stock wheels. I tried to repair them but ended up having a wobbling wheel.

I found some Guillow's 2 inch wheels at a LHS for $1.99 (4 wheels in a pack). They require gluing the wheels together and a little touch of Dremel drill to enlarge the hole.

They look like WWI stock wheels can't tell them from the Jenny stock wheels although they are all black.

They are a bit heavier than stock but more robust and worth the $1.99

Hey Dave, how's your Jenny coming together? I'm curious to see what if anything you will do to beef up the landing gear. Sounds like a potential weak point.

I got a call from my wife today telling me that a very large box had appeared on our front porch. Usually those boxes are addressed to her and are full of shoes, but not this one :D

The motor and servos, etc. arrived yesterday and the Rx is another day or two out but on the way. I will need to get some bullet connectors from the LHS as I forgot to get those with the motor, and may also look for a larger carbon fiber tube. My motor is also going to be too big to fit on the stock tube, though I will probably just end up using the included firewall mount if I can.

Can't wait to get home and have my first look at it all!

Hey I think you're supposed to buy the battery to match the plane, not the other way around!

But seriously, 11.1v would sure juice up the prop speed. It's designed for 7.4. The stock motor might not like it, but you could pick up something that could for cheaper. Maybe someone who has actually tried it will weigh in...

I'm dragging my feet :)

I decided to use a different radio system so I want to install a AR6100 reciever to use with my DX7. So.....I am waiting for it to show up in my mailbox.

One thing I discovered is that once you attach the wings and the wing rigging, you cannot take the wing off unless you want to completely destroy the wing rigging. Therefore the reciever needs to be set up 100% before the wings are attached. Bummer as I do not have my reciever yet.

I did a little bit in the meantime and I will post the pics below.

D. Payne - if you put yours together, feel free to post pics and ideas here. The more insight the better!

oh ya.....I have to compliment horizon hobby on shipping that big box...it only cost me $5 shipping! I've ordered ESC's that were shipped in envelopes that cost me twice that!

Its pretty simple, they have the slot cut out for you already and the fit is perfect-

http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0738.jpg



Just add some foam safe glue on the backs and it aint comming off. Some people have made a modification here and added a thin piece of plywood for extra strength. I havent done that (yet)

I used 9 gram servos here. The manual calls out for 6 gram servos. So basically I am using slightly larger servos and need to make a modification to the servo bay. - no biggie :)

http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0733.jpg



Next I had to drill out the control arms to fit the supplied EZ connector.


http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0747.jpg


Then I attached the control rods to the servo.


http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0748.jpg


Here is what it looks like from the other side. The servos actually sit upside down in the fuse as this pic is taken with the plane sitting upright. The cowl fits over this so it cannot be seen.

Well....these are different, thats for sure. The inner wheel (looks like a lite wheel that GWS would use) is actually made of lite ply. The outer 'hubcap' is plastic. The holes were to small so I had to drill them out so the axle would fit.

http://i158.photobucket.com/albums/t102/aviatordave1967/IMGP0754.jpg


Plan on drilling or expanding the hole on the retaining ring, it wont fit unless you make it fit.

So what do you have to do to make this thing beefier?

You can modify that battery into a 2 cell. So instead of having two 3 cell 850 mah batteries, you could have three 2 cells with a little safe modification if your capable.

I dont see a 3 cell fitting very easily, I have a 2 cell 800mah that will just fit.

Don't attach the rigging as shown in the manual. Run a thin strip of plastic(I use litter bottle) to attach. Tip I found somewhere on the net. Either run the rigging between the strip and wing or as I do, run the rigging through the strip then through the wing.
I call this my recycled jenny. I bought the plane used, the motor is salvaged from a CD drive, the batteries are from cell phones picked up at the recycling center, receiver and servos are both used from other planes. I am changing the controls to pull-pull.

Thats a good idea. I've been running ideas thru my head and havent come up with anything. I'm going to do that, thanks for sharing!

I noticed your cowl is different than the one I got, mine doesnt have a screen mesh like yours.

I didn't like the front of the cowl it had a big hole cut in it. I took it out and installed nylon screen.

A neat work bench is a sign of a sick mind.

Hey Dave,

How do you like the servo arm EZ connectors? I've always thought they looked good but I've never tried them.

Tom.... I use alot of those....On all my planes (even glow powered combat planes).....just make sure they are real tight, and check them periodically....a drop of thin CA in the screw threads really locks them in place permanently if you have any concerns of loosening.....

They work good for this application. I dont dare use them on anything big....my AP plane uses Z bends as do my glow planes (sorry for swearing)

I wouldnt use them on your warbirds, unless for a last resort.

Thanks Dave

I'm trying to figure out the best way to mount my motor. I got a nifty little outrunner from Heads Up RC, but it doesn't fit on the motor mounting stick. It is the exact same problem that Dave had, but unlike Dave I don't have the ability to fabricate a part at work.

I thought about using the motor mount that came with the motor, but then I would have to rebuild the firewall to keep the motor inside the cowling. I am tempted to just epoxy the motor right to the plywood firewall. It fits perfectly in the hole intended for the mounting stick, and it would be in the proper position within the cowling too. My only concern is the strength of such a mount. It nestles right into the hole and would probably hold just fine, but it probably wouldn't be as strong as the stick mount that Dave is using.

I think I will go to my LHS this weekend (after OSU vs. Michigan - go Buckeyes!) to see what other solutions they might offer.

11-16-2007, 03:18 PM

I'll take a picture of the motor fitted into the mount tonight. I think the back of the motor is basically the same as yours, so your solution would work for me too. I just need to find a thin light-weight piece of tubing with an inside diameter of 8mm.

Thanks Dave! I will try to figure out something over the weekend and if I can't find a good solution I will take you up on it.

Does yours fit in the cowling okay? Even with the back of the motor stuck through the firewall, mine barely does. In fact the prop saver will be on the outside of the cowling, whereas the instructions show the prop adapter on the inside with the stock setup. Don't know if I like the look of it that way so I may look for a prop adapter at the LHS.

Fly Time
11-17-2007, 04:58 AM
Here are some pictures illustrating my motor mounting dilema. As you can see, the motor fits quite nicely right onto the firewall without any mounting hardware. The barrel on the back of the motor is 8mm in diameter, exactly the same as the hole in the firewall. It is tempting to just glue it right on and be done with it.

With the motor resting in place, it extends out of the cowling more than enough. In fact, the prop saver cannot be mounted behind the cowling as it is with the stock motor. I don't care for the look of it so will try to find a prop adapter this weekend. The typical bullet-shaped prop adapter looks great on a sport plane, but maybe not so good on a Curtis Jenny. I'll see what I can find.

You are probably right about the prop saver. I have never used one and was wondering about the best way to put the prop on. This one wouldn't be so bad if the screws weren't so long. Maybe I'll just cut them to about half the length.

And I do love this little airplane! Can't wait to get it in the air. I am still waiting on a male JST connector so I can hook up the battery. Heads Up RC agreed to send me one because they mistakenly said the battery came with T-connectors installed. They actually came with JST connectors. Jeff at Heads Up was quick to make it right though, so no complaints.

I've got my Jenny all put together except for the rigging wires, which I will do today. :ws:

I found a solution for the motor mount issue hidden in a large bag of miscellaneous aluminum and brass tubes that I found at a hobby shop on the far end of town (for anyone in the Seattle area, Galaxy Hobby in Lynnwood, WA - great RC selection!). What a great find! $16 for all the tubing I will ever need in just about every size imaginable. I was able to find a piece with a perfect 8mm ID. I cut it to about 3/4 inch then slid it over the motor shaft barrel and carbon fiber tube for a snug fit. I used JB Weld to fuse it all together, being VERY careful to keep the stuff off the motor shaft. Then I widened the hole in the firewall to allow the brass tube to slide in, and shortened the end of the carbon fiber tube so it wouldn't interfere with servo installation. It all fits perfectly!

I was also able to find a length of brass tube that fits perfectly over the landing gear axle. Following the advice from other modelers, I drilled out the cheapo plastic wheels, cut the tube to the exact width of the wheel and tapped the tube into place. The wheels turn freely with no wobble and will hopefully be stronger.

The only real problem I encountered was with the soft plastic wheel collars. I could not get then over the wheel axles. I trird reaming one out just a little, but then as I was trying to tap it onto the axle it slipped out and flew somewhere onto the garage floor. I crawled around for about 10 minutes but never found it! :roll: I'm now using metal wheel collars instead.

The top wing installation makes you pre-drill a small hole on top of the struts. I just used my x-acto knife and made small pilot holes. This is where you need to take time to make sure the wing is true to the world.

Good luck on the maiden!

I thought I would share my solution for mounting my Ele 1500kv motor.
1) I removed the firewall mount from the motor.
2) I placed the kit's motor mount tube inside the Ele's firewall mount.
3) I used this assembly to center the Ele's mount on the Jenny's ply firewall.
4) I traced the outline of the Ele's mount.
5) I removed the offending part of the Jenny's firewall.
6) I then C/A'd a piece of light ply to the inside of the Jenny's firewall.
7) Finally I screwed the Ele's mount to the new ply.

This recessed the motor just enough to let the cowl fit perfectly.

I made a mess with the C/A when I reglued the new ply piece...It seems there was a lot of paint on the inside of the Jenny's firewall.

I flew the Jenny today a bunch of times. I needed a little more nose weight and I might make the bottom wings take in a bit more dihedral to soften the turns.

Nice flying Dave. That looks like fun!

I'm surprised to hear you need more nose weight given your motor upgrade. I thought that too after my first flight, but then I realized the battery was not all the way forward. I was mushing all over the place and didn't feel like I had very precise control. It flies much better now.

The WOW RC batteries that you and I use have a thin layer of foam wrapped around each end, which makes it a tight squeeze to get them all the way in there. To make it easier, I used some hot glue to afix the motor leads to the bottom of the motor mount so they are not in the way. It is still tight, but the battery now slides in nicely so that about 1/2 is visible through the opening in the bottom of the cowl. Mine balances perfectly like that.

Hey doug -

I took the foam part off the batteries to make life easier for me, it fits in real nice now. I am using 2 different WOWRC batteries, a 500 & 800 mah. The 800 works fine and balances perfect. The 500 needed more nose weight so I taped a washer to the battery and that did the trick.

What did you use to secure that brass tube to your motor with? My RTV idea didnt work out so well and the motor got a little loose.

Grasshopper turned me on to JB Weld when I was trying to dress up my P-47 landing gear with faux gear doors. I didn't get a good bond to the milk carton plastic I was using so they didn't last long, but that is what I used on my Jenny motor mount stick. It takes awhile to set (give it 24 hours), but it feels rock solid.

Not neatly. 2 cells is a snug fit, so you would need to reconstruct the battery compartment. As it is the battery slides between the plastic cowling and the bottom of the plywood motor mount box, so you would either need to re-build the ply structure or cut away some of the cowling. It might also give you some balancing issues, though I'm sure you could make it work. IMO, you would be better off buying some 2 cell batteris. They are pretty cheap compared to bigger li-pos, and provide all the power this little airplane needs.

It worked great joining steel to brass to carbon fiber. It should work fine on nylon too, but who knows? Whatever you use I would recommend roughing up all the surfaces first and then giving it plenty of time to cure.

Hey Dave, how did the motor and prop combo work for you? If I'm not mistaken, your motor is a little stronger but with lower RPM than mine, and you are turning a bigger prop. Obviously it flies great, but I'm curious about what WOT looks like and how long your flight time is.

It worked out OK. I really never went over 1/2 throttle, even on takeoff. That motor was not secured properly so I cant tell you how it performed over half throttle. I'll give it a go this weekend, the motor had pleny of umphh as it produces 12 0z of thrust for a 8 oz plane.

I'm pleased with my set up. I switched to a 7x3 prop which allows me to climb at about a 45 degree angle just above stall speed. Very cool! 1/2 throttle gives me a nice gentle cruise and 15-20 minutes of flight time. Only thing I don't care for is the sound of the motor. It has a high pitch whine that is louder than I was expecting. Not too bad though. At least I can hear what my motor is doing.

Dave,

I've got the OK from the financial department (you know, the missus LOL) to order this on Friday. I'll go with your setup, since it saves me over $60. If you can make me a mount, I would greatly appreciate it. Just let me know what I owe you and where to send it.

I am sure I will have a bunch of stupid questions......of course, I could just get a case or two of Icehouse and have it on standby if you want to come out and show me the ropes.....LOL

Hey Kev, maybe you should get one of these instead. Due out any day now. Same power setup, and probably a great slow flyer just like the Jenny.

I gotta give E-Flite credit fopr stepping out of the box a little. Whoda thunk to make a Piper Pawnee ARF? And their new T-Craft looks REALLY nice. What I would like to see: a P-61 Black Widow with about a 50" wing span.

You can get creative, but I glued at one end and glued at the other end. Foam safe CA works or 5 min epoxy.

Once you see how it goes, it is quite simple.

So, glue the thread to the hole in the strut? No knot? I am thinking like this: thread a little rigging thru, so there is a small amount on one side, and the rest out the other side; glue to hole in strut; when glue is dry, cut small end, thread thru remainder of holes, hold taut, glue to final hole in strut; when dry, cut excess. Sound about right? Do I glue each hole?

I also used CA with little squares of plastic from a water bottle to glue over the end of the threads. I got that advice from on here somewhere. Only thing I did different was to poke the thread through to the bottom of the wing (using a sewing needle) so the plastic and glue was out of sight.

Doug,

Any pics? I am not picturing this in my feeble head.

Lucky for you I am working from home today. Or at least trying. This WattFlyer stuff sure can be a productivity killer.

Anyway, as you can see from the pictures, I ran the thread through the hole in the strut (which was already there), then I pushed it through the foam right next to the strut using a sewing needle. Then I cut a small square of plastic from a beverage bottle and put a drop of foam safe CA on the concave side. I pulled the thread snug (not too tight) and gave the area a squirt of CA accelerator then pressed the plastic piece in place. Cut off the excess thread and it's done! On the top wing there was no need to push the thread through to the other side since it attaches from the bottom already, but I used the same technique other than that.

The motor/prop combo I used has plenty of power, you can feel it while you hang onto the plane and go WOT. I would have like to see how my vertical was but the dang thing was getting loose cuz of the RTV. I'm sure it will go straight up if you want it to.

Interesting product. I might have to check that out for myself. For something like the Jenny, I could probably just double the wire back through the fuselage and be okay. Then you wouldn't be able to make fun of me and my 20th century technology anymore!

I dont think its all that powerful. WOT gives plenty of up power, but I could use more. Its just my preferance, I'm a guy who thinks that there is no such thing as too much power. It fits the Jenny fine AFAIC, I'd like to see the eflite 250 in action to compare performance. Anyways, the price was 25% of Eflite, so thats good enuf for me:)

The motor gives take offs in a few feet and gets you out of trouble if needed. Throttle management gives you realistic flight.

Sounds about like mine. I have needed that extra power a few times already. My dog loves to chase my planes around the park. As soon as they are on the ground he looses interest, but when they are in the air he is going for the kill! The Jenny is a great plane to taunt him with, because I can fly it all around the field at 8-10'. He runs right along with it, and if it gets low, he will jump for it! A couple times I realized I was getting too low, and that is when I need "combat power" to avoid the jaws of airplane death! Thankfully, it jumps up pretty quickly at WOT! :D

The wind was dead calm today, so I took it up for a test flight around the cul du sac. I let it go pretty high, probably 300-400 feet, and just let it float around over my neighborhood. She's a beauty to watch!

Dave, do you have dimensions for each tube (lengths, I mean). Also, would you have the opportunity to fabricate a new tube or two sometime for me? In case this one isn't long enough......

Got my tail feathers glued on, and they look straight. Also put in my servos, got the control horns on and linked up. Did you guys have to cut down the pushrods some? Mine were too long to allow free travel in both directions.

Tomorrow I will velcro in the RX and hook up the servos, then mount the wings (minus the rigging) and LG so I have something to take to the club meeting for show and tell.

Whatever you use, let it set up part way before you join the pieces so you don't have the excess running where you don't want it. And since it is a tight fit, you won't need much. I actually think Sumo would work, but you really have to account for it expanding.

OK well I took the Jenny to the club meeting and she was a hit. One question for those of you who have already built her:

Were the main cabanes on the fuse tilted? I noticed after the CA was dry on all the struts the wings are slightly canted. I am told by some veteran pilots I should be able to counter it with some rudder trim, but still......

I can flex it with some force, but it springs back to the off-square original fit. It's like it was made that way at the factory.

Also, Dave, did you need my address again for those new mounts? If so I can send it again.

Otherwise, she was oooooohed and ahhhhhed over tonight, which made me feel good. :)

I think I understand your question......

When you look at mine head on, the cabanes supporting the upper wing from the fuselage lean slightly to the left. Or maybe right - I would have to look. It's a very slight lean, and I don't think I even noticed until I was all done. It certainly doesn't affect handling.

I was flying mine this morning and a flock of geese came over the field at about 75'. There were probably 15 or 20 in a nice V formation heading south. My Jenny was headed north, and when they passed I added some throttle and turned back to join the formation. I never got in real close to them, but I did match their speed and alititude and eased into the left side of their formation, about 20 feet out. They didn't seem to mind at all! The little yellow Jenny stayed with them for about 200 yards before I turned off.

I've got a Fly Cam One coming for Christmas....I think. Though I'm not sure the Jenny is capable of hauling much.

The place that I was flying would be a good place for that to happen again. In addition to the geese overhead, there were about 50 more camped out on the soccer field I was flying over. They probably follow the river as they fly. There were also a bunch of sea gulls that flew off as soon as the Jenny came near, but the geese did not seem threatened. And rightly so. If I hit one, I'm pretty sure the Jenny would have come down!

OK I had enough of the old nylon mount Dave fabricated for me the first time to attempt the mount again, this time using JB Weld. I used a small piece of clear tape to hold the stock mount rod onto the end of the motor shaft, then shmeared the JB on both the metal shaft and CF rod, then slid the nylon tube over the join. THE MOTOR ASSEMBLY IS NOW IN THE VICE, POSITIONED SO NOTHING CAN DRIP INTO THE MOTOR HOUSING! I can not stress that enough. LOL I will let this set for a few hours, prolly til morning, to check the strength.

Dave, the extra mounts I plan on using on the SE5a when that becomes available. I appreciate and wish to thank you for them. If EFlite comes out with some more of these parkflyer warbirds, I may indeed need a dozen. LOL

Here is an alternate way to support the hinge. I saw this on another Jenny Saturday when we flew indoors. Just a plastic flexible hinge slotted into the rudder and glued into the fuse.

[that crack is where I broke it before]

Well, I've lurked on this thread since day 1, and bought my Jenny a few weeks ago, but couldn't find the time to start the assembly until today. After about 4 hours, I have the fuselage and tail complete, radio gear tested, esc programmed, and ran up the motor. I still need to mount the wings and landing gear and add the rigging, then I'm ready to test fly.

I went with the E-Flite 250 motor and 10A esc, and a 2S 800 SMC brand lipo, intended for the Blade heli. My lhs didn't have the 6x5 prop, so I'll try it with the 7x5.

After seeing the posts here about the weak spot on the rudder, I reinforced that area with strapping tape, as well as running a strip of it along the hor. stab. in front of the hinge, top and bottom, and the same on the elevator. That mod really stiffened the somewhat floppy foam, to the point where I think it's as stiff as a balsa tail would be. We'll see how it holds up in flight.

Thanks to all the posters here for the valuable input for those of us who follow along later!

Here is my fix for the weak spot on the rudder and elevator. Also you can see some of the wing brace wires. I run the brace wires through plastic strip where the wings meet the fuselage so the wings can be removed without cutting the wires.

neat...pull-pull set up. Where did you get the wire and crimps?

I do not use wire. I use upholstery thread. The blue tubes it is running through is from cotton swab. I tie the thread at the contron horn, run it throught the tube to the sevro arm, through hole in one side of the arm then to hole on other side of the arm, then through tube to contron horn. Pull tight and tie. Now center the control and use sliver of wood to wedge the thread tight at the servo arm. After test flight and getting the controls set where you want them put drop of white glue on each knot and the wood slivers at the servo arms. On the elevators I tie a glass bead on the thread first, run the thread through the holes in the sevro arm. Put another glass bead on the other end of the thread. The glass beads are only about 2 inches from the sevro arm. Now tie thread to top elevator of control horn on one side, run thought tube, then glass bead, other tube and tie to top of contron horn on other side of elevator. Do same on bottom elevator control horns and pull tight. Center elevator and put drop of white glue on glass beads before flying. Split elevators can be used with this setup.

Nice setup, degreen60, I like the pull-pull controls. I used a large version on the D VII in my avatar, but my big old fingers might not handle that at the Jenny's scale! I went for a cheap and easy fix (I hope) on this little model. I might get some time this weekend to finish the plane, as I "think" I have all my Christmas shopping done.

Hi folks, Just wanted to introduce myself to you all. This is my first 3 channel plane and my first bi-plane. I learned on a 4 channel cessna (Art-Tech) which I believe Hobby Lobby sells in the states.

I maidened the Jenny 2 days ago in light and variable winds. 2-3 mph and changing directions all of the time. I must say I found it quite a handful. I was expecting a much less stressful flight. Having learned on Aileron planes and now flying a plane with rudder control only, I found it harder to point it where I wanted it. Ended up rather badly with a snapped off fin, rudder horn section of the rudder broke off and smashed outer hub of the rubbishy wheels that are supplied with the kit plus a few stress creases on both wings. :mad: I flew it with a 620mA Lipo. CG was as per instructions.

Tomorrow morning I will try again (if it is calm) with an 800mA battery for just a little more speed and penetration. Just the smallest amount of breeze seems to knock the poor girl around. Maybe I was flying too slowly the other day. The park I chose for the maiden is just around the corner and is quite small, so I didn't want to fly it very high (and end up messing with the trees.

Anyhow, just thought I would say g'day and will let you know how attempt number 2 goes.

Welcome Bruce. As you have already learned, the Jenny is indeed a handfull with even just a little wind. I enjoy flying it most in the calm air at dawn. As for CG, mine flies better just a little nose heavy.

I have had problems with the rudder (fixed it up by pushing a toothpick into the trailing edge of the rudder at a downward angle toward the control horn), and the wheels broke just like yours (added brass tubes through the middle and filled the cracks and hub center with hot glue - no problems since).

I've had no problems with my wings. Did you add the rigging wires? If not, you should. It does add strength.

FYI, a higher capacity battery will not give you more speed. It will add weight and give you a longer flight time, but unless you are increasing the voltage, the motor will not run any faster (I'm assuming both of your batteries are 2 cell lipos).

Good luck with your next flight!

What a difference a day makes.... Patched Jenny up last night and drove down to Sydney to fly with some park flyer friends.

It was a 7:00 am start and zero wind. The grass there was too long for rog so hand launched her. 15 minutes on the first pack and 20 minutes on the second (800mA Loong-max)

She flew like a true elegant lady and I also got to loop and spin her. Last spin was about 15 rotations and she points exactly where you want her to when you exit the spin. Now very impressed and relieved that I can fly her.
Cheers. Bruce.......:D

Well, the holiday season was just too hectic for me to get back in the shop, even for a few hours, but I finally found the time tonight to finish up the Jenny. The wing mounting was straight forward, but I found my patience getting stretched thin with the rigging! I persevered, though, and got it all strung as a single continuous line, tensioned, tied off, and secured with the foam safe CA. It certainly stiffened the whole wing assembly, and I think it was well worth the trouble. I found a nice pilot of appropriate size in my "used airframe parts supply" (crashed model chop shop), and installed him in the rear cockpit. The other mod. I made to the kit was to toss the funky ply/plastic wheels out, and replace them with Dubro 1.86" microlights (3.2g ea.), with the spokes painted yellow to match the plane. Looks good. The wheels were a little loose on the axles, so I sleeved them with 3/16' long brass tube of 3/32 OD, a perfect fit on the wire axle, and a pass of the 3/32 drill bit matched the wheels to the sleeve. They have zero wobble, and are very sturdy. I used the supplied wheel retainers, slid on the axle up to the brass sleeve, then dremelled the excess wire off, which left enough burr on the axle end to prevent the retainer from ever coming off. I'm very pleased with the model, and eagerly anticipate it's maiden, as soon as our seemingly endless rainstorms let up.
Brad.

BradT,

Sounds great. Nice work on the rigging, I could not figure out a way to make it work as one continuous line, so mine is in 2 sections.

As for the wheels, I may have to keep your mod in the back of my mind if (when) the stock wheels break. :)

BradT
01-07-2008, 03:15 AM
Kev, to do the rigging as 1 pull, I started at the lower left rear hole, strung through to the lower right rear, then diagonally up and forward to the upper right front, back across to the upper left front, straight back to the upper left rear, diagonally down to the lower left front, etc., etc. You wind up with both front and rear rigged, along with an X between the front and rear struts at both ends of the wing.

No maiden today, the forecast break in the weather didn't show. Tomorrow is supposed to be nice, but I'll be working all of the 9 hrs of daylight, so that's no help! Hopefully we'll get a decent day next weekend. Sat., Jan. 19th, there's a big indoor meet about an hour's drive from me, so I'll maiden it there, if I have too. I bought the kit for these kinds of events, as well as calm day flying, so that'll be a good test for it.

Well, I flew.....I actually let my buddy John fly first (he is a much more experienced pilot), and we found a problem with the rudder linkage. Got that sorted out, and a hard landing busted one of the wheels. Those are going byebye. John had a pair of Dubro ultalight wheels that might just look acceptable, and will be a little more robust. Then I flew her. Did a couple laps, but the gym we use is considerably smaller than the one Dave flies in. So I brought her in, and landed with no problem. Shoulda quit there.....

Took her up again, this time for video. (I will try to post this tomorrow) Turned a little too sharply, overcorrected, and headed for a backboard....whoops. Tried to go under, chopped the throttle, and she nosed right into the floor. Broke the other wheel (no biggie), broke part of the underside of the cowl, and found two cracks in the fuse, one on each side, right behind the cowl. They run almost alongside the cowl. Opened up the crack a little when I got home, and dripped a little CA into it; she is downstairs now letting that cure.

She was flying nice til the "incident". I hope to take her next week and try again. It is just a tight area for me to fly in. But, gotta practice to get it down.

Not happy she came home damaged, but we all crash, right?

They seem a little more robust than the stock POS wheels. They don't look as good, but right now I am wanting strength, not looks. I kept the stock wheels for a later day.

Also, went with the APC 10 x 3.8SF electric prop; looking to slow her down a little bit for better handling in our confined-space gym we use. For outdoor use, I plan on using the GWS 9x4.7 I had on it prior.

For the power system I am using (TowerPro 2712-12 with 12A ESC from HeadsUpRC), Jeff's tests show on 2S this particular prop pulls 6.5 amps while producing 12oz thrust and a pitch speed of 17mph. So amp-wise, I am good to go.
