Design and development

The Trio-Twister 103 was designed to comply with the Fédération Aéronautique Internationale microlight category and the U.S. FAR 103 Ultralight Vehicles rules, hence its designation. It carries a German DULV certification. It features a 30 m2 (320 sq ft) parachute-style wing, single-place accommodation, tricycle landing gear and one 28 hp (21 kW) single cylinder, two-stroke, air-cooled Hirth F-33 aircraft engine mounted in pusher configuration.[1]

The aircraft carriage is a simple frame design with a central canopy attachment, built from bolted aluminium tubing. In flight steering is accomplished via foot pedals that actuate the canopy brakes, creating roll and yaw. On the ground the aircraft has nosewheel steering. The main landing gear incorporates spring rod suspension. The design employs a tilting seat to allow the pilot to see up and backwards to ensure that canopy inflates correctly.[1]

The aircraft has an empty weight of 80 kg (176 lb) and a gross weight of 160 kg (353 lb), giving a useful load of 80 kg (176 lb). With full fuel of 10 litres (2.2 imp gal; 2.6 US gal) the payload for pilot and baggage is 73 kg (161 lb).[1]
