Learn about belt drives, wheels, and tank treads while constructing a dune racer, a four-wheel-drive A.T.V. with a belt drive and high-grip tires, or even a scrambling stair-walking machine. Set up either a fun conveyer belt and make models of a belt sander or a snow scooter with a three-gear tread. The possibilities are endless when the 28-page manual guides your motor-powered vehicle building and experiments with step-by-step illustrated instructions!
