Gerald,

We have found that with the drill or CIM motor you will have a drive system that runs reliably if the following conditions are met:

1. Use chains or spur gears, do not use the right angle gearbox.
2. Final rpm of the wheel, calculated from the free speed of the motor, should be approximately 200-250 rpm for an 8" wheel. Example-bosch motor and gearbox had an output speed of 450 rpm in low, a 2:1 sprocket/chain reduction to the 8" wheel equals 225 rpm at the wheel. If you use a different size wheel than change the sprocket ratio (3:1 for 12" wheel).

We have used the skyway wheels every year. Wheelchair, 3x8 and 2x8 foam and the pneumatic. Your goal for this coming year should be simple and reliable.
