The RagWing RW9 Motor Bipe is a family of single seat, open-frame fuselage, open-cockpit, single engine ultralight aircraft designed by Roger Mann and sold as plans by RagWing Aircraft Designs for amateur construction.
The RW9 achieves its light weight in part due to its completely open-frame tube fuselage.
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.
[1][2][3] The same basic airframe design was also used to produce the parasol wing RagWing RW16 Aerial.
