Re: Bad MiniCIMs... failing to consistently start?

I am guessing your set up is slowly but surely causing your motors to fail. I agree with others that brushes seem to be at least part of the failure mode.

Pictures would help too.

Best of luck!

The team we were with in 2013 damaged a Frisbee shooter motor by doing exactly what the OP was doing, though without the adapters. The side loads from only 3-4 shots, with high compression (and high side load), was all it took to damage the sleeve bearings at the "bottom" end of the motor.
