## Design and development

The Trident was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 450 kg (992 lb). The Trident features a strut-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit with a rigid boat hull, retractable tricycle landing gear and a single engine in pusher configuration.[1]

The aircraft is made from bolted-together aluminum tubing, with its double surface wing covered in Dacron sailcloth and its boat hull made from either fibreglass or carbon fibre and Kevlar. Its 10.5 m (34.4 ft) span Hazard wing has struts and uses an "A" frame weight-shift control bar. The powerplant is a twin cylinder, liquid-cooled, two-stroke, dual-ignition 64 hp (48 kW) Rotax 582 engine or a four-cylinder, air and liquid-cooled, four-stroke, dual-ignition 80 hp (60 kW) Rotax 912UL engine or a 78 hp (58 kW) converted Smart Car four stroke turbocharged engine. All engines are fitted with a clutch that stops the propeller from turning when the engine is at idle to permit water handling. The boat hull features a water rudder.[1]

Starting in 2005 the frame and wing portion of the aircraft was taken from the Skyrider Sonic ultralight trike, built by Skyrider Flugschule.[1]
