This is the inflatable racecourse that allows you to conduct your own races using two remote controlled speedboats. Each 8" long boat is controlled with a separate remote (two included) that provides individual control of each boat¿s dual-propeller system, allowing forward, backward, left and right movement--even spins. When fully inflated and filled with water, the 67" long oval racecourse requires boats to navigate hairpin turns, narrow chicanes, and long straight-aways in order to complete a full lap. The racecourse is constructed of the same durable polyethylene used in commercial water slides, so it will resist tears and punctures, even during the most competitive races. Races can last up to three minutes from a 45-second charge for each boat. Each remote requires a battery. For indoor or outdoor play. 67" L x 39 1/4" W x 6" H. (2 lbs.)
