Apparently the sleeve bearing at the end of the motor with the brushes had become severely worn and the rotor was dragging on the stator magnets. The shooter wheel was mounted directly on the min-CIM shaft.

Thanks.

No we're aren't but we haven't had any problems with the Versaplantary gearboxes or bearings. If that becomes a problem we might have to modify our design to avoid cantilevered shafts but so far so good. These gearboxes seem to be be built very well as far as I can tell. Hopefully we can get through multiple competitions with out any problems.
