A motor overload should be caused only by a bad propeller (as in: the pitch completely off), a seized bearing (damaged motor, did you have a crash?) or a motor blocked by something (touching the arm plastic or a screw too long cutting into the wires). It's not hard for an ESC to measure the current draw, if so designed. Or a bad battery that drops the voltage and creates a condition similar to an overloaded motor
A prop hard to screw on doesn't make any difference
Can you motor spin freely? Does one of the motor feel different when you spin it by hand? Did you add propeller or motor protectors that could have caused a long screw to damage the motor?
It's not that it's hard to screw the thread does not seem to catch properly.
Never had a crash touch wood.
