The Rans S-21 Outbound is an American STOL homebuilt aircraft that was designed by Randy Schlitter and is under development by Rans Designs of Hays, Kansas, introduced at AirVenture in 2016. The aircraft is intended to be supplied as a quick-build kit for amateur construction.[1]
Design and development
The S-21 Outbound features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cabin accessed via doors, fixed tricycle landing gear or optionally conventional landing gear and a single engine in tractor configuration.[1]
The aircraft is made from aluminum sheet, with both leading edge and trailing edge extruded spars. The sheet metal parts employ final-size matched holes to reduce builder errors and speed construction. Its 28 ft (8.5 m) span wing mounts flaps and has a wing area of 141 sq ft (13.1 m2). The standard engine used is the 180 hp (134 kW) Continental Titan X-340 powerplant. Tundra tires up to 26 in (66 cm) may be fitted.[1][2]
The aircraft has a typical empty weight of 985 lb (447 kg) and a gross weight of 1,800 lb (820 kg), giving a useful load of 815 lb (370 kg). With full fuel of 31.75 U.S. gallons (120.2 L; 26.44 imp gal) the payload for the crew/pilot, passengers and baggage is 625 lb (283 kg).[1][2]
The S-21 will compete with the CubCrafters Carbon Cub EX and the American Legend Super Legend HP in the kit aircraft market.[3]
