The Ugears Rescue Hovercraft is a 1:24 scale wooden model of a sleek, twin-propeller all-terrain hovercraft. This DIY wooden model is driven by a spring motor, with a windup ratchet key located on the craft's undercarriage. A Start/Stop switch allows you to wind the engine by giving ten clockwise turns, then engage the motor as the twin thrust propellers spin and the boat executes graceful, preprogrammed left and right turns over a distance of 3 meters, imitating the gentle swaying motion of real hovercraft. With 383 parts and a "Medium" difficulty level, the Rescue Hovercraft model boat promises __ hours or more of enjoyable assembly time as you dream of the rescues your boat will make.
