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.[1][2][3]

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.[1][2][3]

The aircraft has a stall speed of 15 mph (24 km/h).[1][2][3]
