I was flying my e-Flite Corsair from Horizon Hobby and decided to play with the flaps.
I was going too slow as I turned the flaps off, and this resulted in a wing-tip stall that I was not able to recover from. - She came down hard and broke apart. - it will be repaired and she will fly again, since she is my 2nd favorite plane I have.
Lesson learned the hard way - Regain your airspeed before turning off the flaps. - (But only if you like your plane and want to keep it in one piece!) :-)
