It would be nice if there was an easy fix for the locked rotor. I've gone through my share of HV ESC returns for warrenty issues. This one is out of warrenty and it just up and quit working one day. I would be more open to spending some money on it if it was one of my screw ups or atleast had some fun do it. Can't hurt to take the rotor out and give the inside a cleaning. Might help. Thanks for the tip.
