Design and development

edit

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.[1]

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.[1]

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).[1]

The Sonic's trike structure is also incorporated in the Ramphos Trident amphibious trike.[1]
