The RagWing RW1 Ultra-Piet is a family of single seat, parasol wing, single engine ultralight aircraft designed by Roger Mann and sold as plans by RagWing Aircraft Designs for amateur construction.
The RW1 was designed as an FAR 103 Ultralight Vehicles compliant aircraft that would have an empty weight within that category's empty weight limit. The RW1 was designed as a 3/4 scale ultralight version of the classic 1920s vintage Pietenpol Air Camper.
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 and the standard engine was originally the Kawasaki 440. The Volkswagen air-cooled engine has been used, as well as the Half VW and 2si 460.
Partial kits and construction kits were available in the late 1990s, but today the series are only offered as plans. Reported construction time is 300âÂÂ500 hours.
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.
