When I throw it by hand it directly stall. I'm using a FS-I6 with FS-I6a and everything is correctly set upCan you elaborate? When you say "it doesn't fly" what exactly do you mean? What radio are you using? Have you set the RXs up correctly? Have you set the throws? Etc.
Do you think a 1000kv with a 10x6 prop will work ?I'd say you are under powered. FT recommends 2212, 1050kv and 9x4.5 prop for the Cub. I'm running a 2212 1000kv and 9x4.5 on mine. While I cannot say it flies great(my lack of skill and stick time), it definitely does not stall on launch. The plane design does tend to tip stall at low speed.
I don't have a landing I used to have a 3D printed one but I don't use it anymore because it was to hard to take-off on the groundHave you tried taking off from the ground? Sometimes its hard to get enough speed on a hand throw, particularly when trying to do it by yourself. That can be even worse if the plane is under powered, though i dont think yours should be unflyably under powered with that setup.
A bit tail heavy. I used to have a 2200 kv with 6x3.5 on my tiny trainer and it was perfect but the tiny trainer and the simple cub are two different planeIve got an 1808 2400 that runs a 6x4 just fine on a tiny trainer. Id think you should be able to get in the air with that setup. Hows the CG?
@Aslansmonkey I beg to differ. I do agree that the motor is not ideal but it should not be 100% unflyable. I really dont think thats the problem hes having IMHO.
As far as motor recommendations, you pretty much have to check the specs on the motor.
These 2212s for example will make even less power with 930kv and 10x6 prop, although it would be very efficient. According to this sheet, that motors sweet spot is 1400 and 9x5 prop at 910 grams of thrust but that is still only 180 grams of thrust more than he has now, about 25%. A 25% decrease in power is not enough to be unflyable.

Just dont want to send the poor fella to get another motor if that is not 100% the problem...
the motor that is being used is ppc the tiny trainer would be really nose heavy. i think a storch would be betterThe Simple Cub, I'll add, isn't the best flyer. I've had several and it was the plane I had my first successful flights on, but there are easier birds to fly. If cost is the factor, he might be better off building the Mini Trainer, which will fly fine on the motor he's using, and you can still google and find the plans. Two sheets of dollar tree foam board is cheaper than a new motor OR a 9" prop.
