# Skyrider Sonic

The Skyrider Sonic is a German ultralight trike, designed and produced by Skyrider Flugschule. The aircraft is supplied as a complete ready-to-fly-aircraft.

## Design and development

The Sonic was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). The aircraft has a maximum gross weight of 450 kg (992 lb). It features a strut-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit, tricycle landing gear and a single engine in pusher configuration.

The aircraft is made from square welded stainless steel tubing, with its double surface wing covered in Dacron sailcloth. Its 9.8 m (32.2 ft) span Hazard 12 wing is supported by struts and uses an "A" frame weight-shift control bar. The powerplant is a four stroke turbocharged 85 hp (63 kW) Smart Car automotive conversion engine or, optionally, a twin cylinder, liquid-cooled, two-stroke, dual-ignition 64 hp (48 kW) Rotax 582 aircraft engine.

With the Smart car engine the Sonic has an empty weight of 165 kg (364 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 285 kg (628 lb). With full fuel of 60 litres (13 imp gal; 16 US gal) the payload is 221 kg (487 lb).

The Sonic's trike structure is also incorporated in the Ramphos Trident amphibious trike.
