I know from experience that a blown motor will get VERY hot. I tried a CD in my Revo and it unloaded so much that the motor (10XL) spun relatively unloaded. Well, that's bad and it got very hot. Next time I ran it, it had a lot less power but got blisteringly hot. Mine never cogged though. Someone else used the rotor for a 7XL motor and it ran fine, so the rotor was fine. The coils just somewhat burned up. So I wonder if the problem is not the rotor, but one of the coils?

As others have said, it could be a cold solder joint, or just a toasted motor. I would try resoldering. Hopefully it's just that...
