The LSA STOL King is of conventional tube and fabric design, approximately the size of a Cub, with a full glass enclosure and a tall stance for very rough field operation. Slow flights of 16 mph can be achieved and stall speeds of 15 mph let you land in some of the most remote areas of the world.
The Preceptor STOL King is an American STOL amateur-built aircraft that was designed and produced by Preceptor Aircraft, of Rutherfordton, North Carolina. When it was available the aircraft was supplied as plans or as a kit for amateur construction.
Design and development
The STOL King features a strut-braced high-wing, a two-seats-in-tandem enclosed cockpit that is 32.5 in (83 cm) wide, fixed conventional landing gear, and a single-engine in tractor configuration.
The aircraft fuselage is made from welded steel tubing, with the wings of aluminum structure, with its flying surfaces covered in doped aircraft fabric. Its 31.5 ft (9.6 m) span wing has an area of 158.2 sq ft (14.70 m2) and is fitted with flaps and leading-edge slots. The wing is supported by “V”-struts and jury struts and can be folded for ground transportation or storage. Acceptable installed power is 75 to 150 hp (56 to 112 kW). Engines used include the 75 hp (56 kW) Volkswagen air-cooled engine, the 108 to 116 hp (81 to 87 kW) Lycoming O-235, and the 150 hp (112 kW) Lycoming O-320 four-stroke powerplants.
The aircraft has a stall speed of 15 mph (24 km/h).
Six examples had been completed and flown by December 2011.
