Trio-Twister 103

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.

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.
