110" Elipsoid - Aveox F-10 - 8 cells - 70 ounces AUW.
the only other electric sailplane was a wal-mart wing on a self cut fuselage. Killed it a couple weeks ago. gotta cut a new fuselage. Oh well wasn't all that happy with that one anyway.

It's a fantastic little plane, imo. Very capable, and with a good brushless setup, quite nimble and quick....but still able to be flown in small areas.

I think my buddy is flying his with a brushed motor, Endoplasma with a gearbox and performs very well.

Ifly a Greatplanes Spectra, stock motor. I purchased this after a failed attempt of converting a Spirit to Electric. It flies well, but is heavy with stock equip and standard 7 cell.

I was considering upgrading, but have decided to go with a slow/park flyer instead. I currently have a post in the park/slow flyer section looking for suggestions, if you have any info.

OK here goes. 5 years ago I impulse bought a Windstar EP glider and all the goodies to make her fly. I just assembled it last week and maidened her last Saturday. I installed the stock Mabuchi 540 brushed motor, Hitec SP-1003 cutoff, a 1400 Mah Nicad battery. I put about 5 flights on her and maybe got her to thermal for about 5 minutes. :o

I fly a Graupner Cumulus 98. She's powered by the geared Graupner Speed 480, with a Hitec Focus III guiding it. This was my first EP sailplane, and I wouldn't trade it for anything!!!

I'll add my thermal fleet. Sorry only two of them are EP at the moment but one is in consideration and the DLG is getting a EP fuselage version soon.

The red and yellow plane is my F5J comp glider which is a Poly Sergio 2.2meter with a speed 400 and comsmotech planetary gearbox running on a 8 cell Kan 1050 or GP1100 pack.

The blue and yellow plane is my 2meter Electra ARF with a Graupner speed 600 race also running on 8 cells but a Sub C pack.

The big white scale thingy is my 5 meter Nimbus. Still haven't figured out how to get that one in the air but she'll probably get a slimer on a pod or something.

Then the in flight yellow and balsa colored one is my Quickflick IID scratchbuilt discus launch glider designed by my good friend Paul Daniels in Aus. More info on this one can be gotten from me as short kits are now available for the lucky folks in the states. I am working on a Eflite park 370 outrunner powered fuselage for this one.

Other than these I fly a bunch of slope gliders mostly wings. :)

Hey Bruno the windstar was my first epower glider and my first ever 43 minute flight .Only mod was a Graupner Cam 9/5 folding prop. The prop alone made a world of difference.

ELECTRIC PARK/GLIDERS


They can do loops and simple aerobatics, but are very good at thermal
soaring. The Aerobird and the T-Hawk, which are often mentioned as first
parkflyers, glide and thermal pretty well.

Some are RTF which are fully built, include all the radio gear with everything installed. Battery and charger are included with the RTF planes. Some are ARFs where you assemble the simple package, then add your own radio equipment. Some are available either way.


Easy Star - RTF -
This is a Park Glider - can be flown as parkflyer or glider
Great keep in the car plane!

Easy Glider - This is probably too large to be considered a park flyer but the combination of great flying ability, tough Elapor construction and great
thermal or slope soaring ability makes this an excellent first electric
sailplane.

First electric sailplane(sort of): Graupner Terry - hey, it thermals!
Second: Polk Hobbies Charlotte
Third: Multiplex Easy Glider Electric( wish they came out with this sooner!)
Terry goes much better with lipos/stock motor/prop.
Charlotte needs to have wing reinforcements right out of the box. Otherwise stock setup and for 90 bucks, it flies well.
Easy Glider Electric, what more can I say. Flies great on stock setup, flies awesome on a AXi 2808/24(250 watts @26 amps), Tanic Pack 2220 mah 3s lipo, 11x7 CAM prop and spinner, and CC35. Had lots of glitching to sort out though. Vertical climbs on 3/4 throttle.:D

Planes in order of electrification -
1) Wattage THERMALAIR - flew wit strock motor and 9x6 prop - well enough to get the "bug" - Put in a hot buggy motor and 3.3 gb and 13x7 - flew like mad until it died in an irragation ditch.
2) Olly-II - power pod to begin with, flew ok but suffered in the turns. Cut the nose off and have put a wide variety of powerplants in - from 6-10 cells and now has an MP-Jet 28-20/7 outrunner (@300 watts on 10 cells - climbs VERY well)
3) APEX from Dymond - great flyer, but I'm not fond of the blow molded fuse - using the wings to make a new plane someday
4) Palio Sport - great flying plane on 250-300 watts - did I mention a GREAT flyer? Wing rod bent and replaced with an inferior substitute - I cried when it died.
5) Hong Kong V -an ebay buy for my birthday - re-maiden soon, an RX issue put it into the ground back in January.

The Spectra is a good starting point. As far as a radio goes--any good 4 channel will do nicely if it has a small receiver. You wont use 4 channels but that is the fewest channel radio that I recommend. A six channel would be better if you can afford it. I say this with an eye toward the future. My choice would be either a Hitec Optic 6 or the Futaba 6EXA. I would use mini servos such as Hitec HS81's although you could use standard servos with a weight penalty. There is enough room for them. I would go with the new ESC's from Great Planes that are LiPo compatable as well as NiCd and NiMh compatable. The 35 or 45 amp model works just fine. The stock motor is marginal but can be used with a gear box. I prefer an inline gear box like the MPI units from Hobby Lobby and others. A 3.5:1 would be ok with a matching prop. The prop size would depend on cell count. If you went brushless there are many combinations that would work.

Maybe there is too much data there but its a starting point. I'm sure others on the forum have their opinions as well. Hear them all out and choose what you feel is best for you. Advice is cheap and not always good.

Wow you guy's have a real collection:eek: .

Well mine are a little more modest but here they are:

E-Flight Ascent- Gone now but I may get another.

Cermark Dragonfly - Really small fly's OK but the Ascent was much better in thermals.

Thunder Tiger Windstar - Got it free from the garbage can, rebuilt and too about 9 oz. out of it. This actually fly's pretty good.

Ace Whisper - a small 1.5 meter speed 400 (like the Ascent) all wood glider. I lightened this one also. Fly's great.

GWS Slow Stick :rolleyes: - Well it thermals great! Stay up all day:p .

Zagi - Another one that thermals well.

Goldberg Gentle Lady - Well it has an electric radio :D .

Thinking about a warmliner like Hobby Lobby "Ion". I have an AXI 28/10 and a Jeti 40 controller begging for a home :D .

I currently fly a Hangar 9 Aspire glider that I converted to EP. Hacker B20 L15, Maxon 4:1 GB, 12x6 prop and a 3S TP2100 lipo pack. Weight RTF is 38 oz. Nice flying sailplane that can get 6-7 launches per pack.

In the shop I have a Bird of Time ARF I'm converting to EP and doing some wing work on (spoilers and a little carbon). Planning on an AF 05 geared brushless for it.

Also slowly working on a Poly Sergio 2M. Will use either a Hacker B20 L18 or L15 depending on whether a 2S or 3S lipo will balance it out.

Started with an E-Flite Ascent using a geared Hacker B20 S22. Nice little park glider... got too small, too quickly for these old eyes so I sold it.

EP gliders for sport flying take all the work out of launching. :)

Had huge amounts of fun with the two Goldberg Electras I have had. Frequently had close to hour long flights. One was with the stock motor, the other with a torque wound Mabuchi. Lower RPMs with longer props.

Another impressive plane,not a glider, but could ride thermals, was the Kyosho Cessna Cardinal.

I have what might be called an E-Flite Ascent. It is fully battle tested. I have probably crashed it at least a dozen times. So what the heck, I fix it. Finally found out why I was crashing it. One was that the internal control rods were sticking because of the manufacturer's glue had globbed at the exit points in the tube fuse. I solved that by installing them on the outside through guide tubes I created with balsa and fiberglassing. Works real good now. No binding. Other problem was that the stock prop gave very little power. I've taken it down to 6x3 and now it can fly almost like a hotliner. I guess the last problem that I solved was I don't hand launch myself anymore. I'm not quick enough back on the stick to keep it in the air. Yippie!!! I finally have flown it without crashing three times in a row. Does anyone know of a nice e-glider that I can build from plans?
"Women Fly Too" and they can crash real good:D

OK....I have many gliders and electrics....I keep flying this one. It's an older electric called an Astro Challenger. I built it around 1985 from a kit. It has an Astro 05 FAI cobalt motor geared 2.5 to 1 with silver brushes swinging a 13x7 Cam folder, Great Planes ESC (for Lipos) and a 3S1P 2100mah Kokam Lipoly pack. Minimum of 15 climbs! I can launch it while holding it out in front of me pointing straight up.....with full throttle....just open my fingers and let go! Lipoly batteries have completely changed this plane! Before I flew it on a 7 cell zapped pack. It was OK....but now it's fantastic! I highly reccomend this glider if you can find one. It thermals like a dream and inverted passes low in front of yourself is a crowd pleaser!:D

Hangar 9 Aspire is a great 2M glider. I converted one to EP back when the ARF glider version was still offered. Still one of my favorite planes.

I run a Hacker B20 L18 with 4:1 Maxon GB, 3S 2100 lipo, and a 12x6 folder. Climbs out at 60-70 and the AUW is 38oz.

Brewer - are you the pilot I sold the Estarter to on your move back to Utah?

If you don't have a gear box on the Aspire, add one and get a larger prop. You will pleased with the added climb out power.

Hi

Here's my entry into the world of thermals.
Thunder Tiger Soaring Star.

2 metre wings
4 channels (airelons - on seperate channels for spoilers when needed)
40 amp ESC from Cape Sailplanes
540 brushed motor - direct drive
2S1P 2,2 amp LiPo

Was very impressed with one of our members who stayed up for 67 minutes one Sunday. :rolleyes:
Should be ready for maiden this week-end

Let me know how it flys, My longest flight on mine is 30 minutes, although I had to leave several thermals because it was getting pretty far out there.
Hint: keep it fast near the ground on turbulent days.

Add a Cermark Easy Electro 72. A friend strained his through a pine tree and I ended up with the fuselage.
Cermark discontinued the Electro, but still had a wing in stock. Copied the tail feathers off of the Alpa 180 and put a new prop on it. Working on the radio gear now. Took a little break, don't think I'll have it ready for the AM though.

Might wait for the Berg 4L to come in, save the 555 for something else, maybe another Kadet.:D

Good luck, I use a 6 cell 2000mah nimh, I was wondering how the weight change for the battery would effect the cg. Let us know how it flew.

Hi All

The weight change was in my favour and balanced the plane out nicely. :)

Maiden on Saturday went well and my instructor stayed up with it for 12 minutes. No thermals early in the morning and left it for later.

Second flight was 13 minutes and all I can say is it flies great, still no thermals, but my other club has better potential and we'll see what happens there.

Hangar 9 Aspire is a great 2M glider. I converted one to EP back when the ARF glider version was still offered. Still one of my favorite planes.

I run a Hacker B20 L18 with 4:1 Maxon GB, 3S 2100 lipo, and a 12x6 folder. Climbs out at 60-70 and the AUW is 38oz.

Brewer - are you the pilot I sold the Estarter to on your move back to Utah?

If you don't have a gear box on the Aspire, add one and get a larger prop. You will pleased with the added climb out power.

SG sierra gold many thanks for the advice on adding a gear box to my aspire. i have done so. used a park zone p51 mustang motor and gearbox because i had one. had to add little weight to make up the differance. figured this out at my first test flight. also purchased a better nim hi battery. local hobby shop did not have a lipo. also added larger prop. you are right, i am extreemly pleased with climb power plus,flight time under power has increased ten fold.. thank you, thank you, thank you.

It's always interesting to see what others are flying. :)

My "flyers" are":

Castor 2.5 - F10LMR, 7 or 10 cell CP1700's, 14x9.5 or 13x7. Just finished.
XL3200 - 1409/2Y, 3.7:1, 14 CP1700's, 16x10
Sophisticated Lady V-tail, S400, 3.8:1, 8 to 10 cells (600AE or 1700AU), 11x8. This one will be getting a BL soon.
SOBOX Storm - 1409/2Y, 3.7:1, 10 - 2000's, 13x7

The Lady is my favorite to just go out and "fluff around" with. On a nice day she gets a 2 minute motor run climb and then I can just about put down the radio and watch for at least 15 minutes.

I'll not get into the in progress bunch. :rolleyes: Like the AVA-E fuse and the Aquila wings.

All time favorite of mine is my ancient Astro-Flight "Challenger". Still being flown with its original geared Astro 05 FAI on seven cell SANYO 1700 SCRC packs, spinning a 12X6 folder. ESC is an Astro Flight, servos are Hitec HS-101 and RX is a trusty, old FMA Fortress. Heavy? By today's standards, yes, but it still flies superbly nice when one considers it doesn't have ailerons. It does have flaps though.

Also have an Omega 1.8 powered by a direct drive long can Speed 400 motor spinning a 6X3 folder prop. A four channel affair that soars with the best.

Ground guidance is provided by a Futaba 8 "Super" TX on both.

Newest is the 100 inch span Queen Bee- see my post in Deltas- undergoing a Phasor15/4 nosejob- until I got on here tonight, that is... :D Nicknamed GLIDEZILLA!

A converted 10 foot Bird of Time with a Marathon outrunner and an 8 cell Zagi highrate NIMH pack. Elegant!

An Aspire 2 meter converted to electric with LIGHTNESS in mind- until I got annoyed with the S400 w redrive minimal climbrate. An MP Jet Speed 600 class redrive brushless will soon improve the departure angle of this graceful thermal angel.

A V-BAT converted to a rocket plane VTO! Whoa! A wee bit of hangar rash.. oops.. has it on the back burner at the mo...

A Candy with a towhook added for high-start ooomph.

and last... but definitely least...

A mere fond memory of my recently departed Ascent- eaten by a vulture laden Godzilla Thermal- But hey! Whatta way to GO! Straight up till it disapeared in a BUZZARD BOOMER! A tear and a grin all at once... Gonna miss that lil bird... but what a last flight!!! Sure felt weird with a TX in my hands and nothing left to steer in sight... :O

I feel your pain my friend.

I lost a single channel Ace High glider to one of them voracious thermals back in 1970. At first I was thrilled to have been able to manage to join in with the buzzards in the free climbing adventure of the thermal after the little .049 Cox engine had quit running.

After about ten minutes I realized the thing was climbing too fast for my taste. No amount of left or right rudder would get it out of that thermal, and away she went.

Devastated? Sure I was, but learned my lesson well. Stay away from sailplane eating thermals unless equipped with spoilers and or flaperons. :D

The Omega range looks to be the same as the Highlight range over here in the UK.

I've been flying my Highlight Unlimited 1.8 poly for a few years now, and it really is a superb performer.

It started life with a geared S400 motor and 7 cells, but now it sports a direct-drive Mega 1615/5, 9x5 prop and 8xGP1100 NiMHs.

The biggest mod was to ditch that awful foam tail and substitute a home-made item from balsa. The V-tail is removable via single screw, and folds flat for storage as the halves of the tail are joined with a hinge. Not only that, but both servos are inset into the tail surfaces themselves which gets rid of those horrible snakes and gives more room in the nose for the powertrain.

Q, this is the stuff of another thread- GETTING DOWN!!! For my first year of soaring, FINDING and staying in a thermal and controlling with enough finesse to actually climb reliably was a thrill- but THEN success turned scary in the boomers when you find it awfully high and still climbing - now what?

Suddenly, without spoilers or flaps your only alternative is to dive it at Vbsd (better slow down!!!) till it imitates a howling flapping ornithopter in METEOR MODE. I lost an E-Aspire and a Goldberg Electra to wing failures from this scenario! One fuse cored (an empty) tennis court at 70, the other fuse is still in a dense swamp near here, left for future archeologists to ponder- cause I sure can't find it!

GRAUPNER used to have a very nice "Spoiler Kit" that was designed for 2 meter and larger sailplanes. I have no clue as to whether they are still available or not. They were relatively easy to install and very effective. I had a set on a three meter affair. :)

I'll chime in! I'm just getting back into RC after a 5 year 'vacation' while building a real airplane. The big one was sold, so now I'm playing with smaller toys again. This is my first post here in WattFlyer too!

I just finished a scratch-built electric glider, as yet without a name (suggestions welcome!). The details:
The wing is attic fodder, a glass-bagged foam core from a HLG I designed and kitted years ago (Corn Dogger).
The fuselage is balsa, covered with a layer of 3.4oz glass (attached with water base polyurethane). V-tail is built up balsa.
Power is a JustGoFly 450XT on 3S1P 1300 Lipo, CoolRunning ESC. 10x8 Aeronaut blades on a BB hub. Cowling is 'lost foam' epoxy-glass.
Output: 6800 rpm at 13.5 A (145 watts)
Weight: 23 oz, so almost exactly 100 watts/lb.I haven't flown it yet, despite it being finished for almost 2 weeks! Yes, it's killin me. :eek: Hopefully I'll be able to sneak out to the field sometime tomorrow or Saturday morning and commit it to the air.

I'm also looking forward to the flight report.

JustPlaneChris
12-24-2005, 05:40 AM
Hi Jason,

The wingspan is 60". I did get a chance to fly it today, even though the wind was gusting to 30 mph! :eek:

Despite the wind, it flew well. I was actually wishing it was a bit heavier, of course. :D The little 450XT easily hauled it up at a 60-70 degree angle, and I hooked a couple of good thermals, but didn't dare take it too far downwind. The ailerons are programmed to raise as spoilerons, and they worked really well. Surprisingly, I didn't even need any elevator mix when deployed. It just assumed a nice level attitude with a tremendous sink rate. Sweet!

I guess this could be classified as a "warmliner on a budget". At 100 watts/lb it's not a screamer, but it has a brisk climb and nimble handling. And the price is hard to beat, being a recycled wing and a scratch fuselage. I can't wait to fly it in more reasonable conditions. :cool:

1. Ellipsoid 110" (Deceased) Mega 22/20/3E, CC 60 ESC, 3:1 gear drive, 16x11 CF Folding Prop, Tanic 14.8v 2480mah battery pac.
755 watts (maintainable for at least 2-3 minutes without overheating the batteries) Drawing 56 amps. Zero - 400 ft (Flying field Height limit) in under 5 seconds. look for thermals or just putt around, when she gets low again take the EXPRESS Elevator to the top again. a blast to fly.
2. GP Siren Phasor 30/3, CF 12x8 Prop, 40 amp Jeti ESC, 11.1v Tanic 2480mah battery. real fun to fly, but not like my Ellipsoid was. All in All, a great E-glider. (not really a Hot liner, more of a medium liner) flat out she goes about 70-80.

The ellipsoid did not like to go straight down with power---too fast, no controls whatso ever. Almost lost her that way.

I fly the E-Flite Ascent. But since my original stock motor went, haven't flown it for about a month. I put in a HET Typhoon 6/20 with matching 10 amp esc and hope that will motivate it. MotoCalc says it will fly with the 6x4 prop I have on it. I'm fixing the wing right now, as it has been through a ton of crashes trying to learn how to fly electrics. I'd toss it and it would go nose into the ground. Someone finally told me I had to throw hard and haven't crashed it since. :DLOL!!! Dumb me. But my dream is to build myself a scale sailplane with a piggyback motor. Any suggestions on a plan I can purchase and where I can find the piggyback drive tower that goes just behind the canopy. I've seen pics, but never've been able to find a retailer. Of course if there is something that looks scale with the nose mounted motor that would be wonderful. I fly off a dry lake bed. so there's no problem with room, just the wind.:)

This thread is getting kind of old, but what the heck...

I just picked up a Multiplex EasyGlider Electric. I just finished my second flight on it. Stock speed 400 gearbox & prop. The only battery pack I had handy for it was a little GWS 750 mAh 8 cell NiMH pack. It takes a good while to get to full height, and that battery is good for about 3 climbs.

I just finished charging up the 8 cell, 1050 mAh KAN pack, which should give a bit more pull.

Climbs take patience with this stock system, but this plane is really not about climbing performance.

I managed to get 14 minutes of flying with about 6 minutes of motor burn. I don't think that's considered very good, but I'm happy with it. (It was also about 30 F outside, with a 5-7 mph wind) I don't think there were any thermals around.

I don't want to spend a heck of a lot of money on a power system for this plane, as it seems to defeat the point of a thermal soarer to me.

This is my first glider, and it is a lot of fun to fly. It is every bit as much fun as my brushless Formosa, which is an absolute hoot. It's a completely different type of skill.

Scale Sailplanes with Self Launch Systems cost the big buck (at least the 4 meter one I had priced out at www.icare-rc.com (http://www.icare-rc.com),

These planes are out of this world beautiful, all of them are scale, for intermediate to advanced pilots.

They have pictures of them on the website of the SLS and some basic info how they work.

If you want a good penetrator for wind look at www.arthobby.com (http://www.arthobby.com) I have been talking with Andre there about the IBIS-E 3.1 meter and the Serenity-E 2.5 meter.

Just can't make up my mind. too many choices out there for gliders.

Thanks Big, Never knew about Art Hobby. They have some nice stuff. Right now I'm just building from scratch various airplanes accross the spectrum of type (sailplanes, freeflight, jets, but no smellies) I like building more than flying, but sailplanes are sedate and that matches my demeanor. Good luck on choosing your glider. I guess it must be one that you can handle with a throw which would probably eliminate anything much more than 100 inches, unless of course you have a slope to drop it off of. :-)

"E-bay Item" for about 200-220 for a glass fuze and obeche covered wings (?) or Balsa, cant remember which) you really cant go wrong. There's a long thread on RCU about this glider and 3-4 people who bought them and their thrills of building.

My goodness, I've difficulty enough with a plane of 50 inches.:D Maybe gender has something to do with it. I'm female and just don't have that ooomph to sling around a 5-7 pound plane. Do the larger winged planes hand launch better because of their wing area? I know if I don't throw my Ascent really hard, by the time I get on the stick, it is on the ground. I guess maybe that rule everyone at the flying field keeps telling me is true. Larger wing spans are easier to control and fly. I'll take a look on EBay and see what you told me about. Thanks

EDF Fanatic:

My ellipsoid jumped out of my hands, i.e. with a light toss at 50% power she will go straight ahead with a slight climb, if you throw her slightly "uphill". think back to the song of the seventies "I've got the POWER".

With the power set up I had, it was never a problem getting her aloft. It was controlling her at full throttle...

There are sveral places to go:

www.espritmodels.com (http://www.espritmodels.com)
www.hobby-lobby.com (http://www.hobby-lobby.com) (I think that's right)
If you go to Esprit, tell Zb that you want it to really go, and he will set up the power plant for you.

For batteries check your LHS for Tanic Pacs they give out 15-20C and that is lots of power.

If you get an ellipsoid, look for my earlier post for the power plant....just up upgrade your servos to something a little more powerful.

She was a wonderful thermal hunter, and with power to go to 400ft in under 5 seconds, you could conceivably fly as long as your transmitter battery lasts...

03-19-2006, 09:37 PM
Big, Thanks. I know both of the sites and have worked with both. The people at both are absolutely wonderful. Esprit helped me outfit several models I have. Right now, all I'm looking for is sedate flying. The need for speed isn't all that compelling, but occasionally I will fly a prop or edf jet. I prefer the slow turns and gentle glides more. But will have to wait for a commercially made model. That's why I was asking if anyone knew of plans that an intermediate flyer and builder could do that at least looks scale or is scale, with the exception of the motor. Again, thanks for your help.

I used to have the Ascent and it was an easy glider to launch. It should launch with just a gentle throw, double check your CG and when you launch dont throw it at to much of an up angel. Launch fairly level mayby about 10 degress up. It should glid out 50 or 60 feet easily.
Really dont know of any scale looking 1.5 or 2 meter ARF's out there.

03-21-2006, 03:19 PM
Epoxy. Believe it or not, I have only been successful with hard throws to get the airspeed up. I'm slow getting back to the stick. I need the extra speed, as by the time I'm back on the sticks it is gliding normally. I never was successful with any hand launched airplane doing it like you suggest. CG's are perfect and weights usually came in under specs. I got the Ascent because my first glider, an EFlite Odyssey just didn't fly with the power system it had. I appreciate all you guys writing and helping me. Since I build most everything nowadays, I'm still looking for a sailplane that I can build from plans that at least looks like one of the scale planes. Most of the commercial planes I've seen that are scale looking consistently have a Mabuchi 540/550 brushed motor that is just too weak for the plane they put it in. So, I'm still looking.

I thought of one other thing, on my Ascent the stock prop was junk. I changed to the black Graupner 6X3 Cam and it was like a new supercharged motor;) . If you have not tried that you will at least find it is way more efficent.

Epoxy, I actually had no folding props. so I used a APC 6x4 and it worked fairly well, for about a year. A few weeks ago the stock motor that came with it finally gave up the ghost. I guess with close to 40 flights and running higher amps, it was bound to happen. I'm now running a HET Typhoon 6/20 brushless and Tsunami-10 ESC with same prop and is drawing about 7amps at max throttle. Now if I can only get it to fly again. I tried today and it wouldn't trim out. May be the stronger motor. Put a little more right and down thrust and rechecked the controls. Will try again tomorrow. Maybe have someone trim it for me as I'm absolutely terrible at doing so. But from what I can see the present setup will fly with about the same authority as the stock setup I had

Hi,

Just decided to post my 2 meter electric sailplane too.

Its a Windex 1200C scratch build from plans. It was designed by Nick Ziroli and the plans are from Model Airplane News.

Its a balsa constructions. The fuse is planked. The power system is a small AXI motor direct drive 6x3.5 folder prop. and 3 cell lipos. Whole thing weighs 21oz. Its my first electric power glider, and I like it. The climb rate is good too, about 30-40 degree.

Just to add, yes, the motor is indeed on the fin.

Dragged aloft by a Eflite Park 400 outrunner, 10x7 eflite prop w/ prop saver (can't afford the folder yet), and Castle Creations-25 ESC. Fuse is covered in white super monokote, wings and tail feathers are transparent red and yellow monokote. First flight was yesterday. Needed lots of down trim, will change incidence angle of wing trailing edge today. The fuse is roomy (about 2in wide) and will take anything you care to install. The Park 400 is lighter than the Astroflight 05 it was designed for, so extended the nose moment by two inches to help with the balance. No additional weight needed. The elliptical wingtips were a new building experience for me, but made no changes except substituting bals for the hardwood spars. Wing trailing edge substituted 3/16in stock for 1/8in. Fuse sides are hard 1/16in balsa instead of 3/16in balsa. Flies like a Ohio Turkey Buzzard!!:p

I'm still flying an old Gruapner Electro Jr, must be nearly 20 years old by now. I've worn out 3 or 4 speed 600s in it and it just keeps on going and going and going. The Vengance (is going on 15 years), a vintage powered sail plane design kitted by Ted Davey, forrunner to the Slick. The baby in the bunch, only two, is the Mini Phoenix, a great little sailplane that will hold its own with the bigger ones, unfortunately it suffers some real quality problems in the fuselage molding - egg shell thin and just as brittle. Now discontinued.

It's nice to see there are others that feel some planes don't need brushless motors to be enjoyed. Although the larger and more performance oriented sailplanes in my hanger are brushless equipt--my more sedate models are fitted with Cobalt and good old Graupner can motors.

There are times when I prefer to actually see my planes in the air rather than a Monokoted blur as they fly past.:D

Brushless does NOT mean high power. Brushless mean 50% better utilization of the battery. Smoother operation. Longer lasting motor.

You can put a brushelss in that is no more powerful than the speed 600 can motor. YOu will just get 50% longer battery runs or you can go down in battery size, giving you a lighter plane for lighter wing loading and better thermaling.

Oh yes, and a motor that is not likely to ever wear out. That too!

Brushless is not just for hop ups!

Well all, I have just about finished my Discus 4m, converted to Electric.
I have a thread here on Wattflyer, and am part of another on RCU.
both are listed as 157" Sailplane.

I will know if this bird leaps out of my hand in two weeks. I should not have trouble getting her airborne at just over half throttle. AUW will be about 9-10lbs. When I get her done this week, I will weigh her for the final time. Only thing left to do is mount the last spoiler servo, the coverplates, switch, and ESC.

Am also trying to figure out how and where I will put cooling vents for the motor, ESC and the batteries.

Franny
05-28-2006, 07:36 PM
Hi Big,

What I did for my BOT was to hinge the back of the canopy and add a micro servo controlled by the throttle and hooked to the front. When the throttle goes up, so does the canopy and it acts like a scoop. Then, when you are soaring about, and the throttle is down, so is the canopy. It seems to work pretty well, but I haven't flown it yet. Check out my last couple of posts in my link above. Bench test seem to go well. Just a thought...

The wing platform design becames from a Hyperbolic courve, on LE and TE.

The fuse is build using 3/16sq hard balsa strips.

This model is a real floater, and a very good thermlist, and that is the real problem.

In So Paulo , where I live we have strong thermals, and I almost lost this model twice.

Recovering from a stall is essentialy the same as in hang gliding. Regain speed by getting the nose down and moving towards the stalled part of the wing. The biggest problem for us hang glider pilots is that instead of pulling back , you need to push forward. The only way that I was able to get over what had become an instinctual act was to fly on a simulator.
It only took about 3 or 4 totally destroyed plains to get me to put down the money to cure the problem.

05-23-2007, 02:35 PM
For about 3 years, I was flying a modified Stylus hand launched RC glider. Scaled the plans up from an article in RCM. Modified it slightly by adding an extra rib bay on each side of the wing, and adding a ply plate in the fuse bottom so I could use a hi-start. Also occassionaly used a Sig pylon mount with a Medallion .049. Great for winter flying, also found out it was easy to to bring around for a catch so you could re-launch without ever touching ground. Eventually dum-thumbed, even though I'm a pincher.

The old Aerotech Phoenix Rocket Powered Boost glider was also a treat to fly, at least until I went into terminal airframe flutter just before burn-out while using a composite G motor. My son once tried to capture a complete launch sequence using his EOS 35 mm camera. He caught 11 frames, with the last just howing the glider tail leaving the launcher. After that, he couldn,t swing fast enough to keep it in view. I had to stand about 40' from the launcher to follow it myself. My Estes Sweet Vee is a LOT more sedate.

Hi Violind

I also fly in real sailplane in Brazil, I have a PW5 full scale.

In models the use of ailerons depends of your flight envelope.

I do prefer no ailerons, and a good dihedral angle, just because in 1000ft hi, it's almost impossible make turns whit a correct mix, between rudder and aileron.

But... this is a matter of preference.

I have a beginner's question here: my glider's weight is 360 grams, if I install an outrunner which has a maximum thrust of 600 grams. It is in the ranges of thrust-to-weight ratio for 3D. This would be great during landing, I can suspend the glider vertically and catch the tailboom without letting the glider touching the ground. Is this possible?

AEAJR
06-11-2007, 05:51 AM
Anything is possible. You just have to see how the motor/battery weight will work in your plane. If that is a thermal glider, a motor/battery that powerful may add too much weight and raise your wign loading too high.

I used this brushless
KM0203800 for Geared Drive

bolts right onto the gear box. The pinion gear from the stock motor attaches to this one with a set screw. Motor is about 2 ounces lighter than the stock motor.

In the shop I have a Bird of Time ARF I'm converting to EP and doing some wing work on (spoilers and a little carbon). Planning on an AF 05 geared brushless for it.

Also slowly working on a Poly Sergio 2M. Will use either a Hacker B20 L18 or L15 depending on whether a 2S or 3S lipo will balance it out.

Started with an E-Flite Ascent using a geared Hacker B20 S22. Nice little park glider... got too small, too quickly for these old eyes so I sold it.

EP gliders for sport flying take all the work out of launching. :)

Do you have any specific suggestions for exactly what motors and ESC and battery combinations would work well in converting an Aspire to EP ??

I saw in your post about the Hacker B20 and Maxon gearbox but I'm not sure about the gearbox issue in the nose of a glider. Do you have any pics of the application so I can copy what you have done ??

A question here, I've heard a lot of good things said about the Skimmer line of E-gliders in other threads, and as such was considering it as a first kit-build. But here I've only seen it mentioned twice. I know the true test of a product is in it's following, so are the Skimmer fans just a small "cult"?

AEAJR
06-08-2008, 09:57 PM
The true test of a product is its following? I am not so sure I agree with that. There are many planes that have large followings that are not "best in class". In many cases distribution and access will determine which are popular and which are not.

And, as we are seeing in all aspects of the hobby, the ARFS have taken over as compared to kits. There are many today who are flyers, not builders, myself included.

However, I have always heard good things about the skimmer both as a kit and as a plane. Based on that it would probably be a very good choice.

The Skimmer, designed by Ted Davey, is a great first build powered glider. Same airfoil as his Vengeance another fine stable flyer. I think you will be real happy with it, particularly with an outrunner and LiPo pack. I got a 30 minute dead air flight this morning on my Cermark Phoenix with Graupner brushed 600 on 2S3200 LiPo. Could have gone longer but it was getting hot. Still had about 1 AH left when I put it on charge (CellPro 4s).

I fly both of these gliders with the supplied brushed motors but with a 2 cell 3200 lipo. Don't really try for long flights. Just go up with power, glide down, then go up again with power.When I get tired after about 30 mins, I land. Really relaxed flying for an old guy.

How does the 2S LIPO compare to a 6 or 7 cell NICAD. (Weighs less with more MAH but likely has less voltage than a 7 cell NICad so what is net performance.)

LiPos are much lighter than NiCads or NiMHs.

As far as voltages, NiMH and NiCad cells are 1.2 volts per cell - LiPos are 3.7 volts per cell - so, in order to have somewhat the equivalent Volts (which is what "pushes" amps through the circuit) you will need 6.16 heavy cells vs 2 lighter LiPo cells for the same amount of power if the amps are the same (P=IE)...

Performance should be better in the lighter airplane...

However - 7 cell NiCad with 8.4V will provide 28% more watts than 2S 7.4V LIPO.

So the question is whether the reduced weight of LIPO offsets power loss of lower voltage.

Test it... it has been my experience that lighter weight improves performance a lot more than a few volts extra from the Nicads. Also, the delivery of power from a Lipo pack seems to be better.

Just finished a BOT ARF conversion to electric and it's ready for shakedowns. The Watt-BOT was a scratch and dent special and needed a bit of work other than the conversion. The covering was messed up in quite a few spots on the wing and I didn't care for the original color scheme. So off it all came from the wing and horizontal stab and on went new. The servo for the flying stab was moved forward to under the wing with the rudder servo and a new pushrod and bellcrank setup installed.

Spoilers were cut into the inner wing panels before recovering and each has a micro servo for opening them. Power is a Head Up R/C 3542-10 BL outrunner with 40 amp ESC swinging a AeroNaut Cam 11 x 6 folder. Amps are supplied by a Maxamp 2100 maH 25 C LiPo. A couple test flights with this setup proved this to be plenty of power. She isn't a rocket,but don't waste any time either. The transparent yellow with red trim Mono-Kote is easy to see with the yellow almost glowing when backlit a bit. Balance was no problem requiring only 2 oz. to bring her to specs. She weighs in at 70 oz. putting her 10 oz over the stock weight,but still only has a wing loading of 8.5 oz./sq.ft.

I got an old Scorpio Condor Magic 29 at a swap meet early this year and am just now getting some parts to get it going.

It needs a motor and a servo and some slight repairs. I'm adding a wheel and some skids on the wing tips and tail. I'm also going to beef up the wing attachment points. Then I might add some paint instead of the plain white that it is.

I plan on putting an E-flite Park 480 with an 11x7 folding prop in this glider. The chart says it should fly with this.

Hope it flies good... It's a big one - 2.9 meter wingspan.

Since my last entry, I purchased a 74" span glider which I believe was kitted by Airtronics a numbr of years ago. The person I bought it from has had to get out of the sport/hobby with advanced CPD Has a Medallion .049 in the nose.

Maybe not technically a glider or sailplane, but I've started to recover my old Lanzo R/C Stick. 9' span, about 1184 square inchs area. Used to have an old Fox .59 on it, but I will be replacing the Fox with an older Saito .52. The chart says the Saito should spin a 13 -4 prop about the same RPM as the Brown Jr I believe Lanzo used back in 1936. I've seen these planes get hour+ flights with only about 5/8 ounce fuel at SAM contests.

I live near a somewhat massive soccer field, my hometown glider is none other than the Speedo 1200mm from Revolution shop, I have been wanting to do a proper review on it, however, I 've got a really good camera but I fly solo and the winds are not very forgiving at low levels... I'll do a full write up later at some point to help out other owners.. great little thing, handles wind like a champ, I'm using a Futaba 9CAP with zero speed offset (its an RG15, its going to get a little draggy for sure) however, fast fast fun...

Now if and when I end up at a bigger field, I use two more Revolution shop gliders, the passer-x, it floats, quite simply its beautiful, sleek, and zooms and loops and does all the fancy stuff...

The other one I fly is actually, thanks to the courtesy of Revolution shop, the prototype Bulero Pro Hi-Wind... its a very casual flyer, VERY capable, fun, light, and beautiful... I have landed this one during sunset, beautiful, final approach looks like a hawk coming in... this one I will recommend like crazy to anyone, its not a euro glass slipper, but oh my, delightfully ol skool yet so contermporary at the same time..

Keep in mind, none of these are dlg type launch gliders, they're easily adaptable to ol' high start however, they're pretty much enjoyable in javelin toss form...

Once again I'm terribly sorry, I fly alone, ergo no in flight pics...

I'll add my thermal fleet. Sorry only two of them are EP at the moment but one is in consideration and the DLG is getting a EP fuselage version soon.

The red and yellow plane is my F5J comp glider which is a Poly Sergio 2.2meter with a speed 400 and comsmotech planetary gearbox running on a 8 cell Kan 1050 or GP1100 pack.

The blue and yellow plane is my 2meter Electra ARF with a Graupner speed 600 race also running on 8 cells but a Sub C pack.

The big white scale thingy is my 5 meter Nimbus. Still haven't figured out how to get that one in the air but she'll probably get a slimer on a pod or something.

Then the in flight yellow and balsa colored one is my Quickflick IID scratchbuilt discus launch glider designed by my good friend Paul Daniels in Aus. More info on this one can be gotten from me as short kits are now available for the lucky folks in the states. I am working on a Eflite park 370 outrunner powered fuselage for this one.

Other than these I fly a bunch of slope gliders mostly wings. :)

Sweet gliders! Do you have any video's of them flying?

My latest sailplane is a Spirit 100 converted to electrical power. The battery will sit on a platform under the canopy and above the servos. The plan for this conversion was not to gain long duration cruise but to use the motor instead of a High Start to boost the acft to sailing height. Using a 1300 mAh lipo, the hope is to get 2 to 3 boosts/battery. Conversion's AUW added just a very few oz's to the unpowered version's. CG fell right into place with no adjustments (dead weight) needed. Still need to add cooling provisions. It has the capability of deploying crow configuration.

So here she is. I electrified her with a AXI2820/10 in the nose, swinging a Graupner 12x6 CAM, getting juice from a 3S2250 Zippy through a JES40 ESC. I also installed 2 spoilers with a micro servo each.
I added some blue stripes to the bottom of the wing, the elevator is removable for easy transportation, and both elevator and rudder servos are up front.

She flies like a dream.

Hey All

Just got an Art Hobby Colibri. Got the flat aileron style wing. Put just a tiny bit more than stock dihedral in it. I will try it as a rudder elevator ship first. If that doesn't work I will go ahead and put the ailerons on it.

Great kits, excellent workmanship, and light. THe Specs called for 4.7 oz, mine came out at 5.7 oz. I may be a heavy builder, but that's still not bad for a 40" span glider.:D

Will post in a different thread on how it flies as soon as it gets a little warmer here in Kansas.

A QUESTIONS FOR THOSE WHO HAVE THE MULTIPLEX "ELECTRIC EASY GLIDER"...

I HAVE BEEN FLYING THIS BIRD FOR A WHILE AND TODAY I DECIDED TO CHECK THE INSTRUCTIONS BECAUSE I DIDN'T REMEMBER HOW I SET THE INCLUDED "MULTICONT X-16 SPEED CONTROLLER" TO RUN WITH LIPO's...

I STILL DON'T KNOW - THE INSTRUCTION BOOK IS PRETTY VAGUE AND I'M GUESSING THAT THE ESC RECOGNIZES THE TYPE OF BATTERY AND NUMBER OF CELLS THAT YOU ARE USING... THE BOOK SHOWS THAT YOU CAN USE FROM 6-8 Ni-Cd/NIMh OR 2 Li-Poly CELLS BUT IT DOES NOT EXPLAIN HOW TO TELL THE ESC WHICH SETUP YOU HAVE.

ANYWAY, I HAVE BEEN RUNNING MINE WITH A 7.4V 2250mah BATTERY PACK WHICH FITS PERFECTLY IN THE BATTERY CAVITY... I HAVE NEVER RUN THE BATTERY DOWN ENOUGH TO CAUSE PROBLEMS BUT... I NOW GO TO A PLACE IN THE MOUNTAINS WHERE YOU CAN FLY FOR A LOOOONG TIME WITH ONE MOTOR RUN TO GET SOME ALTITUDE AND I AM GETTING CONCERNED AS TO THE LENGTH OF TIME I CAN BE UP IN THE AIR... MY RECORD SO FAR IS 1HR 48MINS AND WOULD LIKE TO BEAT THAT WHEN THE CONDITIONS ARE APPROPRIATE...

ANYWAY, ANYHELP WITH THE ESC SETUP WOULD BE GREATLY APPRECIATED.

HAPPY FLYING...

Sounds like you are trying to set the LVC, low voltage cutoff.

Also sounds like you are slope soaring.

I have a Multiplex Brushless ESC. The ESC sets low voltage cut-off based on 65% of the inital voltage. So, a 2 cell pack should be at 8.4V fully charged. That would yield a 5.5V LVC. Lower than most but not really a problem. That is 2.75 V/cell.

Multiplex X-16 works the same way according to the manual on page 18. Nothing for you to adjust.

Now, what this means is, if you fly and the pack is down to 7.9V, you disconnect and reconnect later, the LVC has been set for 65% of 7.9V

Note that if you are slope soaring without the motor, you are using VERY little power. You are only drawing on the order of 200 mah per hour. If your inital motor run is say 30 seconds, you could probably fly safely for 6 horus with Tons of reserve.

Thanks for the reply... Yes, i read page 18 and couldn't find any required adjustments and that got me concerned...

I do slope soaring and yes, it takes a very small run of the motor to get me "out there" and then just fly... Not a problem really...
I got concerned because I do fly at our field also and that requires a lot of engine runs if there are no thermals around... I guess i will have to make sure that I always start with a fully charged pack ... if not, trouble could be around the corner.
Thanks again.

Lots of neat gliders on here, all the stick built models make me want to go out and buy another Gentle Lady. Currently I'm flying a Multiplex Easy Glider and I love it, except for it seems a little heavy, mine comes in just a tad over two pounds. That's with a NiMh 8 cell battery, could probably get that down quite a bit with a LiPo, anyhow!

My real question is in regards to throw distance on Aileron servos, and linkage geometry. I always thought that you wanted to put the push-rod about mid way on the servo control horn, and then attach it closer to the control surface to get more movement, and further away for less. Obviously I missed a geometry lesson someplace, because when setting up my Easy Glider, the only way I could get the recommended control throws was to put on the longest control horn I could find onto the servo, and then set both linkages in the bottom holes. I tried all combinations, and this is the only one that'd give me the recommended 20mm up deflection and 8mm down.

Now the real problem, when landing, if a wing dips and a servo arm catches on grass, I strip a servo. My current thought is to use aileron fairings, and cover the arms, which adds a tiny bit more weight to an already heavy glider... So I've bought them, and it looks like they might work, I cut them out the other night and did a trial fit. However, I'm still annoyed that I have to have such long servo arms on the aileron servos.

Has anyone else experienced this with the EZ glider? And does anyone have some lessons they can give me in Geometry, or any ideas where a good tutorial on the matter resides.

fuzzy,
on all my belly landers i try to put the servos and control linkages on top of the wings and tail so they don't catch on the grass or ground when landing. sometimes the modification is a pain, but its worth it if you figure in the time, effort and expense of changing out stripped servos
. . .and by the way i learned to fly on a gentle lady!!!

jecchile
04-12-2009, 02:44 AM
mid way on the servo control horn, and then attach it closer to the control surface to get more movement

In order to get the most deflection on a control surface, you want to install the pushrod in the outermost hole of the servo arm and the innermost hole of the control surface horn... usually, you don't get so radical and enough throw is obtained by the outermost hole of the servo arm and then the last or next to last at the control horn...

I have never had a problem with the ailerons servos in my EasyGlider and I land on grass all the time... the servo arms are not that long... then again, I purchased the RxR Electric kit so it came with everything installed... my deflection is not even close to 20mm of up and it is pretty even up and down... I think it is less than 25mm (1 inch) combined... perhaps the total deflection is about 20mm.

Good luck...

HI! cbatters...
Thanks, it is a nice looking bird and she will maiden tomorrow (if the winds are down)...
Sorry I can't tell you the propeller size - amazing but the specs for the prop are not in the instruction booklet... each one of the blades is 4.25 inches including the mounting area so I guess that if you count the width of the spinner, which is 1.5 inches, the total width of the prop is 10 inches. I do not know the pitch since I do not have a tool to measure that. All I can say is that if I crank the motor, it really pulls so the glider should climb pretty darn fast.
I hope it flies as good as it looks.:ws:

Sounds like a 10" diameter prop which makes sense with a geared setup. Are the wings foam or built up balsa with covering? (Can't tell from the pics)

GA,
The Garnet is my first DLG so I've got nothing to compare it to but it looks like it launches pretty well to me but dont ask me to estimate launch height as I'd probably be miles out.. The weak link if anything would be my launching rather than the glider. Average time with no obvious lift were coming in about 1.5 to 2 minutes. I had one or two around a minute when I either duffed the launch or hit strong sink. Best flight was about 5 minutes.

The model handles real well never showing any sign of dropping a wing even when severely provoked. I'm very pleased with it.

HI!... the wings are built up balsa with the root ribs made out of plywood... the covering is very nice with only a few light wrinkles that ironed out fine.

Well, I flew it today... after the initial flight for trimming (it required some right rudder) I landed it in order to adjust clevises (I like to do that instead of leaving the trims set in the transmitter - old timer I guess)... then I had 3 other flights - the longest was about 25 minutes - very hard to find thermals today... all in all I am very happy with it and other people at the field liked it too... one guy wants to buy it already.
The motor almost pulls it straight up - too much motor if you ask me - I flew it at about 3/4 throttle to get to altitude. For $69.95 it is a real good deal.

Well, I flew it today... after the initial flight for trimming (it required some right rudder) I landed it in order to adjust clevises (I like to do that instead of leaving the trims set in the transmitter - old timer I guess)... then I had 3 other flights - the longest was about 25 minutes - very hard to find thermals today... all in all I am very happy with it and other people at the field liked it too... one guy wants to buy it already.
The motor almost pulls it straight up - too much motor if you ask me - I flew it at about 3/4 throttle to get to altitude. For $69.95 it is a real good deal.

Sold! Thanks for the info.

Is this what yours actually looks like?

Oh yeah, these Discus Launched gliders require severe strength abilities

if you look at some of the famous "expensive" gliders you'll see as they are composed of carbon fiber, kevlar and fiber glass amazing stuff!
with full flapperons, camber programs etc...

DLGs don't require strength. Height is acheived by technique more than strength.

Oh i was talking Strength as in structure, its why they are all made of composite, i have experienced lots of exploding planes, especially the weak pods, i have only started getting into fiberglassing. fun stuff!

yeah i agree on the technique, and release speed too

i cant make up my mind on what to build, its like the DLG's need lots of strength(structure) so it requires lots of fiberglassing, (cloth) im trying to find alternatives as usually you have to order the different weight cloths, like for the wings you glass all of the wing(top and bottom) with cloth around 2/3oz/sq yd. and then the joints and other hardy glass areas use the 2oz stuff or more

but once you get high like boomers, your plane becomes small! i've lost my radian a few times, had to gun the engine to find her! but i would also like a 100in bird like this sailplane i really like the looks off.(i'll find a picture)

jecchile - Please post pics of your Sky Walker setup when you get a chance. Thinking about ordering one this week.

(No matter what I do to my old 2M, it is never going to get down to 21 ounces so this would be a welcomed addition to my hangar.)

Welcome aboard WattFlyer. I found a pic of a Thermix XXL to share with the group. Very big plane.

Close to buying one of these but wondered if you ever found a similar ARF model with poly fuse instead of balsa? (Field where I fly is rough on the fuse of airplanes.) 63" wingspan with AUW of 21 oz is very interesting.

HI! cbatters...
I have had a couple of gliders that had a "plastic" fuse but they were 2M gliders and a lot heavier than the Sky Walker. Didn't like them very well.

In order to protect the fuse, put clear packing tape on the bottom of the plane... this protects the covering material and it does not show... works great. I do land on grass but our runways are not like a golf course if you know what I mean.

Get one, you'll have fun with it.

I do not have any pictures to post... maybe later will take some.

Have fun.

Thanks for the nudge. I will order mine next week. (I am going to splurge and spend the extra $10 for this one.)

Nice colors - i'm sure that you will enjoy it. Let me know how it flies... Btw - i just checked and they all cost $79.99 now... I guess i got a bargain.
Have fun.

Do you fly the Siren as a thermal ship or are you flying aerobatics.

Have never seen an e-hawk fly. Does it thermal well?
