Design and development

The Fregat-Hydro was designed to comply with the Fédération Aéronautique Internationale microlight category. It features a cable-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit, twin inflatable floats and a single engine in pusher configuration.[1]

The Fregat-Hydro is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth. Its 9.28 m (30.4 ft) span wing is supported by a single tube-type kingpost and uses an "A" frame weight-shift control bar. On the more recent models the powerplant is a modified liquid-cooled, four-stroke, 80 hp (60 kW) Suzuki automotive engine. The aircraft has an empty weight of 230 kg (507 lb) and a gross weight of 500 kg (1,102 lb), giving a useful load of 270 kg (595 lb). With full fuel of 33 litres (7.3 imp gal; 8.7 US gal) the payload is 246 kg (542 lb).[1]
