well, ive just stripped the motors down and quite simply the windings on arm have burnt up. Well one of the sets of 3 have burnt on each motor.
The magnets are coated in the burnt epoxy i presume.
I cant see what the problem could be besides the ESC?
But could it be a ESC problem? What could go wrong with an ESC that would cause it to overload the motor?
p.s. I checked my pinion position and the cans of the motors and there is no worn cans suggesting the pinion being too close to the can.
