The airframe is constructed entirely from wood and covered with aircraft fabric. The landing gear is of conventional configuration with bungee suspension. The cabin is internally 42 in (107 cm) wide and drooped STOL style wingtips are optional. The aircraft's installed power range is 52 to 100 hp (39 to 75 kW) and the standard engine is the 52 hp (39 kW) Rotax 503, although the 70 hp (52 kW) 2si 690 and 73 hp (54 kW) Subaru EA-81 engines have also been used.[1][2][3]
The RW11 is only offered as plans and the designer estimates it will take 500 hours to complete the aircraft.[1][2][3][4]
