The UH-13P Sportsman one of the best performing 2 passenger hover craft we have to offer. It's constructed of foam & plywood making a composite structure which is easy to build and is unsinkable. A single vertical shaft lawnmower engine powers both the thrust propeller and lift fan and enabling the craft to achieve a top speed of 55 mph quietly and efficiently. The 13P also meets the World Hovercraft Federation and Hoverclub of America Formula 25 racing requirements. See Hoverclub of America for more information.
A single engine powers both the thrust propeller and lift fan through a belt drive system. The belt drive allows us to use a reduction drive system to turn the blades. Reducing the rpm of the propeller and fan through a reduction drive lowers blade tip speed enabling extremely quiet operation. The 13P is one of the quietest hovercrafts available today.
In addition to being quiet, the single engine design makes operating the craft easy. Just squeeze the throttle and off you go. We have engineered the drive system to supply the correct amount of power to both the lift fan and thrust propeller at every throttle setting.
