We have seen magnets come off of non-Kevlar wrapped rotors as well from too much RPM, it is never a good idea to run a motor full throttle without a load on it.

It was only 3-4 quick bursts. I didn't keep it full throttle for any good period of time. The problem was that something had happened while I had it on the track, and turned out to be a bad bearing and something a little loose inside the motor. So whatever happened was when I had load on it. I'll get it checked out and hopefully replaced.
Thanks for the replies!
