I have a 500mx that was in a crash and my battery cought fire and my esc let out the magic smoke and I dont know if the esc sent power to the motor while it was not spinning or the heat of the fire through the wires caused it to get very very hot. The motor does run still but is rough and just doesnt sound right and I was wondering if I change the shaft and bearings to get it smooth will it be good to go or is there other stuff that can burn out or go bad from the heat and how would I tell so I can look for stuff when I have it apart. I dont want to buy the shaft if I just have to buy a new motor.

and the blonde said "RECTUM, Hell damn near killed em!!"

It should only be the bearing. But, check that the enameling is not burnt of the windings.

Just finished pitting it back together, the small rear bearing was really ratty so I replaced it and will test as soon as I can.

I suspect it will be fine, My MX is a powerhouse, but is alreay on its 3rd set of bearings in 150 flights, still better than the Scorpion!

Yeah, Align motors are so much better than Scorpion. That is if you want to do some cooking between flights.

The 500mx is definately more powerful than the scorpion 1600 and operating temps are much lower, flight times not as good as the scorpion though.
