The rotor seems ok. No torque means NO torque. I can put 100% throttle and hold it with my hands.
The problems should be within ESC software. I don't think I have rotor failure + software problem at the same time ;) Hasn't anyone had the situation where you can't change any MODE settings?
Can you hear the motor spinning? if so, rotor is dead.
or is it completely dead?
I would try factory reset with motor disconnected. my little tekin rs pro is able to go to some dead end and if I unplug motor (I guess you have to de-solder it) than I am able to get it back running.
