Design and development
The aircraft features a cantilever low-wing, a two-seats in tandem enclosed cockpit under a bubble canopy, fixed or retractable conventional landing gear and a single engine in tractor configuration. The light-sport version for the US market will have fixed landing gear as that category requires.
The aircraft is made from carbon fibre. Its 7.900 m (25.9 ft) span wing mounts flaps. The acceptable power range is 100 to 115 hp (75 to 86 kW) and the standard engines used are the 100 hp (75 kW) Rotax 912S or 912iS and the turbocharged 115 hp (86 kW) Rotax 914 powerplant. The Mustang features electro-hydraulic retractable landing gear, hydraulic disc brakes on the main wheels, dual controls and electrically-operated flaps. The manufacturer has made the aircraft as similar to the original as possible, down to the simulated metal finish, rivets and other details. The SW51 also includes a sound system that provides a Rolls-Royce Merlin engine sound and a smoke generator for start-up smoke simulation.
The aircraft has a typical empty weight of 288 kg (635 lb) and a gross weight of 472.5 kg (1,042 lb), giving a useful load of 184.5 kg (407 lb). With full fuel of 115 litres (25 imp gal; 30 US gal) the payload for pilot, passenger and baggage is 102 kg (225 lb).
