Re: Gearbox/reduction for CIM,RS550,RS540

The guys up the road from us on 612 didn't actually use transmissions for their drive system this year, check them out in Atlanta if you get the chance. They simply used a small pulley on each CIM and a large pulley (almost the same diameter as the lunacy wheels) bolted directly to the corresponding lunacy wheel.
