Instant DownloadPlans exclusively come in digital format and include full scale PDF drawings and a 32-page photo-illustrated PDF book with hovercraft principles of operation. Plans also include the Solidworks CAD files and a link to a free viewer.
This new release of Pegasus plans now includes the native Solidworks files. These files enable you to make changes in CAD before beginning your hovercraft project. The stock design, however, runs on power from from a 3-1/2 hp lawnmower engine. With the law mower enigine, Pegasus will lift a 125-pound payload free of the ground and navigate at about walking speed across any hard, flat surface. IA simple thrust system will significantly increase performance and speed. The craft is built using a simple framework of 1/4-inch plywood, which is skinned over with 1/8-inch plywood. For safety reasons, the engine and lift-fan are enclosed inside the plywood housing at the rear. Control is effected by shifting body weight in the desired direction of travel. A flexible vinyl skirt provides an obstacle clearance of about 8 inches.
Add a thrust system and you have much greater speed and positive directional control. Plans provide ideas on how to do it. Expect to spend about $250 – $350, depending on local materials prices and on whether you buy a used or new engine. Minimal tools and building skills are required.
Plans give an overview of hovercraft theory which you can then put to work by making modifications of your own. Pegasus is designed as a fun and educational project. It wil work over just abpout any reasonably level and hard surface.
