Universal Hovercraft 13PT


The UH-13PT twin trainer is our simplest 2-passenger  hovercraft featuring direct drive engines for simplicity and a virtually  unsinkable foam core hull. The UH-13PT hovercraft makes an excellent  father/son, high school or university learning project. The 13PT is perfect for  beginners with little building experience and veterans looking to add a fun  machine to their collection. Builders will learn composites, mechanics,  aerodynamics, fiberglass and wood working. No welding required.
     This is a twin engine hovercraft; it uses a 10 to 15 hp (Tecumseh, Briggs,  Kohler, Honda or Robin) horizontal shaft thrust engine to turn a 36 inch  2-blade propeller and a 5 to 7 hp vertical shaft lift engine turning a 24 inch  4-blade lift fan. Both engines are direct drive.
     The pointed design produces less planing drag and less high speed drag than a  craft of equal size with a square front end. This translates into a higher  payload capacity, low-power cruising, and a higher top speed. A single joystick  controls two flexible rudders and thrust engine throttle. Lift throttle is  mounted on the dashboard.
     An entry level racing class has been formed for beginner to intermediate  competitors by the Hoverclub of America. This class is based around the 13PT  design. 15 hp is the maximum allowed horsepower (lift engine + thrust engine).  See Hoverclub of  America racing for more information.
