The RW9 was designed as an FAR 103 Ultralight Vehicles compliant biplane that would have an empty weight within that category's 254 lb (115 kg) empty weight limit. The RW9 achieves its light weight in part due to its completely open-frame tube fuselage.[1][2][3]
The RW9's wings are constructed entirely from wood and covered with aircraft fabric. The landing gear is of conventional configuration. The aircraft's installed power range is 22 to 52 hp (16 to 39 kW) and the standard engine is the 38 hp (28 kW) Kawasaki 440A installed in tractor configuration. The 35 hp (26 kW) 2si 460 has also been used.[1][2][3]
The RW9 is available only as plans and reported construction time is 150-175 hours.[1][2][3]
The same basic airframe design was also used to produce the parasol wing RagWing RW16 Aerial.[5]
