Ballistic question
 
Okay, I've had my Ballistic 8.5 for about a year now.. I've overheated it to above 200 before but runs fine still.. I oil the bearings often and they are as smooth as can be. However, it doesn't spin smoothly. I recently got a ballistic 10.5 and it is way faster than the 8.5. So my question is, is the stator shot?

Shot
 
The rotor is probably hurt and maybe the stator. I would take the rotor out of the 10.5 and try it in the 8.5 . I've cooked my share of novaks and when they feel what I call mushy turning the shaft the Stator is bad.

+1 check the rotor first.

When you overheat your motor, you can both damage the stator and weaken (demagnetize) the rotor.

Okay so I'll try the 10.5 rotor in the 8.5 stator and the 8.5 rotor in the 10.5 stator.. Thanks a ton everyone! I'll let you kno how it goes
