Design and development

The RK-5 is derived from the Rolandas Kalinauskas RK-3 Wind. The RK-5 features a strut-braced high wing, a four-seat enclosed cabin accessed via doors, fixed tricycle landing gear and a single engine in tractor configuration. [1] [2]

The aircraft fuselage is made from welded steel tubing supplemented by wooden stringers, while the wing is of wooden structure, all covered in doped aircraft fabric. The 11 m (36.1 ft) span wing has an area of 15.2 m2 (164 sq ft) and mounts flaps. The wing is supported by a single strut on each side with a single jury strut. The standard engine employed is the 140 hp (104 kW) Avia M 332 four-cylinder, inverted, air-cooled, supercharged, inline, four-stroke powerplant. [1] [2] [3]

The aircraft has an empty weight of 450 kg (990 lb) and a gross weight of 900 kg (2,000 lb), giving a useful load of 450 kg (990 lb). It is supplied with a wide range of standard equipment, including leather seats and tinted windows. [1] [2]
