I have just needed the rotor from this motor due to my 500KV motor's rotor was bent after one crush and I needed replacement. Quite nice quality. I don't know about this version but 500KV is very powerful and good performing motors but not available anymore in here.

Good motor. Propeller adapter too bad - has big run-out, provides big vibration! The threaded end of the shaft is bend on several motors.
