Didn't know it at the time. I was looking for stock set up. I have several 3cell 2200 and wanted to use them. Having problems getting motor to run on 3 cell so looking to move back to around a .15 (stock set up) See lots of guys going to the bigger motor set up. I really dont need the speed. will be happy flying at 1/2 or 3/4 throttle. Have seen the stock ones fly and look OK to me. EFlite motors are a little expensive, looking for options.
PS if flys as good as the others will probably be adding flaps & retracks, looks to be addictive
Thanks for your setup ideas
Not sure what's wrong with the Eflite, but if it's bad, you could try Hobbyking for a 25 equivalent at about 1000 KV, and I'll bet she will wake right up.

Maybe: PRODUCT ID: G25-870 US warehouse about $26.

With that KV, you can prop it to run either 3S or 4S... check out ecalc on line to get prop dia and pitch dialed in just right for your desire of power/speed versus flight time.

first that is a great motor you got there. she loves a 10x7e or 10x10e on 3s don't worry she will fly can even get up to 100mph on 4s with a 9x9 or 8x8 my was clocked at 81mph with a 10x10e 3s

BTW, just to be clear, I agree - the Eflite 25 motor is considered a good one, not sure why it would not be getting the job done, unless it's under-propped.

motor runs but only on 4S. I have plenty 2200mAh 3S and is reason I bought plane. For me I don't need to fly 80+. I do have a YAK 54 and only fly it 3/4 throttle. I'll probably go with a HK 15 as suggested. I already have a EFlite 25 ESC lying around. thanks. some great ideas here but I just bought this one as a knock around plane.

I run mine with tape only at over 100mph and never had a problem. But it won't hurt things either

Thanks Kevin, it is quite old, from before I had a good camera, but for illustration purposes figured it was better than some of the new ones which are mostly just flying, not take offs or landings.

I don't use flaps on take off any more either, just landings. No need on take offs, as it's very scale looking without and with you really have to watch the elevator to keep it from popping over on the nose. The roll to take off is also REALLY short, so less scale looking.

It can happen when you don't run up to a high enough speed and then pull up at too high an angle. Stalls a wing, snaps over and in you go. This can be accentuated if you are jamming the throttle forward and pulling up early in the take off roll as now you have too little air speed AND you have a lot of torque from the motor twisting the plane to the left.

If you don't have someone around to help you with those first take offs then try slowly feeding in throttle on take off roll, use rudder to keep the nose straight. Let the TAIL come up before even trying to pull the plane off the ground. Once your tail is flying, then GENTLY pull up into a nice gradual climb out.

As you learn about the plane you will be able to shorten the take off rolls quite a bit, as there is a LOT of power in the stock setup.

Not pushing views, but if you want to see my maiden video I did a TON of take offs and landings with this plane. 2:20 gets you to the start of the series of Take offs and landings, the best example is likely at 4:50 on a running track.

Hope this helps, and good luck,

Thanks Marlin, that video was really helpful. I think I was using way to much throttle and it just torqued over. I guess flying these large warbirds just isn't the same as flying my supercub. I'm still. Going to try and get someone at the field to show me how to take off before I try and fly it again. I got it all glued back together tonight so hopefully Sunday I will have some success!

Well now I just watched a video on YouTube and the guy said if you go to slow on take off it will torque to the left. He said just go full speed ahead and it takes off nice and straight. I need to find a Rc plane school :-(

One of the things I do before I even get a new plane off the ground is do ground testing. So rather than fly it, drive it around on the ground and practice getting up to speed and then shut down as the plane gets light on the wheels. I've done this with every plane, even my scratch builds. Good to know how your plane handles on the ground. You gotta get the tailwheel straght in relation to the rudder and it will get out of adjustment. I knocked mine out last weekend doing crosswind landings since the plane 3 pointed with a good amount of right rudder....Only one one can't ground test well is the Neuiport cuz of it's tail skid....uncontrollable on asphalt....be patient and practice that and see where that get's ya!

Unfortunately I'm just a freshmen at the school of hard knocks, but I think I might make honor roll if I destroy one more plane :-)

Well it's supposed to be pretty windy here tomorrow. I was going to try and go to the field as a guest, but now I think I'm going to find some smooth asphalt and practice on the ground. So the object is to get the tail of the ground and still keep it straight with rudder I assume. That's good advice
