Design and development

The RW1 was designed as an FAR 103 Ultralight Vehicles compliant aircraft that would have an empty weight within that category's 254 lb (115 kg) empty weight limit. The RW1 was designed as a 3/4 scale ultralight version of the classic 1920s vintage Pietenpol Air Camper.^[1][3][7][8]

The airframe is constructed entirely from wood and covered with aircraft fabric. The landing gear is of conventional configuration and the wings are detachable. The aircraft's installed power range is 24 to 48 hp (18 to 36 kW) and the standard engine was originally the 38 hp (28 kW) Kawasaki 440. The Volkswagen air-cooled engine has been used, as well as the 35 hp (26 kW) Half VW and 35 hp (26 kW) 2si 460.^{[1][2][3][4][7][8]}

Partial kits and construction kits were available in the late 1990s, but today the series are only offered as plans. Reported construction time is 300–500 hours.^[1][3]

The same basic airframe design was also used to produce the RW5 which is a replica of the Heath Parasol and the RW6 Rag-A-Muffin.^[1]
