O.K. thanx.....what would I have to do to increase the torque of the 11 tooth motor? I know that the magnets would change it, but they also decrease speed though. I want the most torque gain wiht less speed loss. I've heard of people using the crest spinbrush motor and saying it was a pretty good motor, and that the magnets in it would give you more torque. Would just switching the magnets with the ones form the spinbrush increase the torque any?
