My motor lasted only 4 minutes on a 2s lipo battery before overheating enough to melt the front plastic mounting flange. It appears that the motor is very underated or the prop size is too large - I never even got it into the air so cannot tell if the 22-121400kv motor will actually be enough to power the plane.
Another worry is that there is not enough air flow through the plane body to allow for adequte cooling.
I read somewhere in the forum that another larger motor is recommended for the Phoenix 1600 and would appreciate advice as to what motor to use. I would prefer a motor capable of powering from a 3s lipo.
I have a spare 28-36 1400kv motor available but that seems a bit oversize and heavy for the plane as a small glider.
