Did you run the 2200 installed in a Rc or just holding it in your hand?
Does your electric drill run okay or does it get hot and smoke?
You can take the 2200 apart pretty easy to take a look around inside. Take the front end bell off and install a pinion(for grip and to hold bushing on shaft) then slowly and strongly pull the rotor out. Note the number of bushing on the shaft on both sides of magnets. It should have some clay on the end of the rotor where it was balancing.

It was in my hand!
Runs ok, no heat or smoke!
Took it apart, only one bushing on the front and another on the back. Bearings look ok.
Anything else?
Maybe too much axial play?
Maybe the brass bushing size is wrong?
