if you're blowing the fuses on the CIMs by stopping it with your hand, then it's not geared down enough, end of story. That isn't a problem with friction in your drivetrain. You have 2 options:

1. Change your drive train to gear the CIMs down more. You could accomplish this by putting the 10 tooth sprockets on the output of the gears, and the 45 tooth sprocket on the wheels, and then run the chain between them.

2. Go back to your drills and try to figure out what's wrong with them.
