Ive got 2 motors that I believe the bells are bent. Looking at them they look fine. I had a hard crash into asphault and the # 3 & #4 motors sound like gears grinding when I try to spin them up. I tried to take one of the bells off and stripped the allen bolt out…. Any ideas on how to get the bolt out without drilling it out. motors are Emax LS2207 1600kv if that makes any differenc. Any advise or help would be appreciated
If you have a dremel tool and cutoff wheel you can cut a slot for a flat blade screwdriver. That will help you remove the screw much easier
