Id be a little concerned about putting magnets that powerful that close to the magnets in the motor. Who knows... Maybe they would cancel each other out and you would loose power in the motor.:005:

Seriously though. I think that magnets would weigh an awful lot. Remember, adding weight to the pinion has a MUCH larger effect on the total rotational mass than adding weight on say the wheels.

A crazy Idea I had was wanting to design a slipper clutch that worked like the keyless chuck on a power drill (but smaller obviously). Having numbers around the outside and you just hold the spur and rotated the slipper to dial in your desired tention. That way when you found the tention that worked, you could always go right back to it without guessing.


BTW: So when are you going to start working on the prototype of this slipper idea???:p
