Design and development

The SP Mk2 features a cable-braced hang glider-style high-wing, weight-shift controls, single-place accommodation, foot-launching and landing and a single engine in pusher configuration.[1]

The aircraft uses a standard hang glider wing, made from bolted-together aluminum tubing, with its single surface wing covered in Dacron sailcloth. The wing is supported by a single tube-type kingpost and uses an "A" frame control bar. The engine is a two-stroke, single cylinder Radne Raket 120 of 15 hp (11 kW) that mounts a tuned exhaust, controlled by a foot pedal. Electric starting is provided via a 12-cell Nickel–metal hydride battery. The harness mounts the engine and the 4.6 litres (1.0 imp gal; 1.2 US gal) fuel tank. Each harness was custom made for the individual pilot to provide an exact fit and improve comfort. The harness incorporates a shaped carbon backplate, with a 10 mm (0.39 in) foam insert, neoprene shoulder inserts, an adjustable prone angle and a multi-setting rotation point. Dual retractable cable-braced skids are provided to protect the two, or optionally three-bladed propeller, during take-off and landing.[1]
