TRACKED VEHICLES TO BE ASSEMBLED

Ten models to build, including belt-driven off-road vehicles and machinery. You can build a dune racer with tank tread for rough terrain, a four-wheel drive ATV with belt drive and high-grip tires, a stair walking machine, a fun conveyor belt, a belt sander, a saw belt and a snow scooter with a three-speed tread. Plus, a snowplow and a futuristic truck. The models are powered by a battery-operated motor box. A 44-page manual guides you to model construction and experiments with step-by-step instructions.
