Well it is kind of like a T-Bird @120% with carbon tube wings, stab, and tailboom. Oh and it also uses 148 watts of power via an Axi 2212-12, a Starlink timer, and a Polyquest 2 cell 1200 mah battery. But it is still kinda like a T-Bird. 😉
Hey Jim, It looks like a T Bird that won’t break at the fuselage /pylon connection.
120% of what size TBird?
What gas equivalent would the power system translate to?The model is scaled up 120% from a 1/2 A T-Bird. It is funny that you mention the fuse breaking. Originally it had a wood fuse, broke behind the pylon and had to be replaced. The carbon tailboom is lighter so I am looking for a way to reduce the weight in the nose. I also have a 1/2 A T-Bird that was built right off the plans with electric power that is awsome. With a little help it will do 2 min. on a 5 sec. motor run. I can see how Larry Davidson got hooked. I do not know how to answer your question on power comparison. I have never had a gas model. Scott is a power flyer and has seen this model he could chime in with an opinion. Speaking of power I am commited to making an attempt this year. I made a deal with a power flyer and he has already put an electric model in the air. What do you think about the GRS 1cc motor?
Well, T Birds break at that point. They need cf reinforcing to stay intact.
Be sure to key that stab, it has little bitty fins.
If the GRS is a Fora ( black ) , it will do you nicely. The AstroStar F1P would be a good match. I assume you are looking at F1P. Joe Wagner had kits for a F1P Maverick, also a good choice.I am interested in a E36 motor. I went thru last years E36 ramblings. The online sources all showed OOS on the recommended setup. I’ve never flown electric, have no charger, no knowledge. You might call me a plug and play type. If you have something to sell and will recommend prop/battery setup, I’d buy.
Did you ever decide on a plane for the BIG setup? I know we talked about the 725 Marval. Its a good plane.

Dan, Pm me with your address and contact info and I will get you set up with a E-36 power system. Thanks for the gas info. After our conversation at Lawrenceville I ordered a set of Marval plans. I scaled them down a couple different ways then shelved them for a Maverick. I built a 1/2 A Maverick last year for electric power and it was the best fling model that I have ever built. I am working with a friend that kits RC models for a living on a Maverick knock-off @120%. The kit will be laser cut with a updated spar and a built up vertical stab. Most everything else is Maverick. At 120% it will meet the requirments for F1P, Classic Gas and “A” gas. I hope to have the first prototype next week. I know how much you like the Marval. I have it scaled down to a 36″ wing if you want to build it for E-36 I will send you the plans.
The 120% Maverick sounds like Joe’s size. A Maverick is a force to be dealt with.
Marval at 36″ would be a tiny wing. Whats the area? 270 squares is 52″ span. By the way, watch for it in Model Aviation. Maybe June.
My impression of E36 is that spectacular performance isn’t gonna happen. That won’t keep me from trying. I’m looking at scaling the Tail Firster and using the fin mounted motor. Doug joyce would appreciate it, I think.
Is young Jim going to fly F1P ?
Dan, I’ll offer my humble opinion even though you didn’t ask:
E-36 is the most difficult of all the electric classes. Reason: the rules result in heavy models with limited power. Even with the new battery allowance, it is hard to make the max. Also, E-36’s are very tough to fly in windy weather.
My suggestion: Start with a big model that can be flown both in AMA Electric B and FAI class F1Q with no changes in model configuration. Use a lipo battery and a brushless outrunner motor. Try something as simple as a Sloworm 432 or use one of Jim’s gas model conversions. You will have a lot more fun.
DickI know its a limited performance event. Taking up the bigger class would mean needing a boatload of maxes to stay with you and Frank. I’ve thought about doing the bigger plane. I’m not certain if I’m ready to take the plunge into another event needing 8-12 maxes to place.
Can you recommend a motor equivalent to 21 glow? I don’t know any reference material to check. I know a little about glow engines and appropriate prop/rpm tables. That’s where my knowledge ends. Embarking into new technology is daunting and could get a bit pricey.
And when its done, the electrics aren’t noisy!Dick
as with Luddite dan I would be interested in a motor/prop/battery combo for a starting point for 400-450 Squares model that’s not too wild.
When I look at catalogs the arry of outrunner motors is bewildering.
Roger
I agree..help all us newbies and share your wealth of
information ..we may be interested in getting into the
larger electrics.Thanks
With reference to Jims comparison to a gas powered T-Bird. I’ve watched Larry D’s T-Birds fly on the 2004,5, & 6 Nats videos and Jim’s 1/2 A T-Bird with the brushless outrunner system he as on it will out climb any gas engine that plane could handel except the cyclons and it’s clones, including TEE DEE’s. It’s vertical climb takes place in about a 40 ft circle. 😯 If Jim used the fully alloted 25 second motor run this 1/2 A size T-bird would be almost out of site. When we where flying it Jim was only using a 15 second motor run and a 2 minute max’s would have been extremely easy, I would guess the flight time would more have been on the 3-4 minute range without any thermal activity. I probably got a little wordy with this response but it was the most impressive show of electric pwr. potential I’ve seen.
Scott
Portland, TNThe 1/2 A T-Bird that Scott mentioned is powered by an AXI 2204-54 turning a 7X5 prop. The power is delivered through a Jeti mini 8 amp controller and a Starlink timer from a Polyquest 400ma 3 cell battery. The model is a stock T-Bird with the exception of a peice of basswood on the bottom of the fuse.
On the “A” size model and my F1Q I use the AXI 2212-12 turning a 9X6 prop through a Jeti 30 amp controller and the Starlink timer from a Polyquest 1200 mah 2 cell battery. You could use a 3 cell and a smaller prop but it is too scary for me.
OK Dick it’s your turn…………………..
Frank, I know you are out there…………………..Ok..another question:
Where do you order all the necessary parts ?
And how much investment(cost) are we talk about?thanks
