The aircraft was introduced in 2003 and production ended when the company went out of business in 2005.[2]
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 30m2 parachute-style wing, single-place accommodation, tricycle landing gear and one 280NaN0 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 800NaN0 and a gross weight of 1600NaN0, giving a useful load of 800NaN0. With full fuel of the payload for pilot and baggage is 730NaN0.[1]
