32% in the boxWhat does this mean?
HBjet They 18,22,25 etc are they amounts of overdrive in the v-drive box. The goal is to run a certain amount of overdrive with the prop and turn the maximum rpm that your motor will pull. To much gear and the motor won't be running at its full potential. Kinda like running to large of an impeller and your motor won't turn it. Same concept just a different application.
