Design and development
The TST-1 was the first motor glider in a long line of aircraft produced by the company. The design goals included that it should be economical to build and operate as well as easy to fly, with outstanding soaring capabilities with the engine shut down.
The aircraft has a wooden structure, with some
fibreglass parts. The span wing employs a Wortmann FX 61-184
airfoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine.

Hirth F-23 and
Rotax 447. The engine is mounted in pusher configuration in a
faired pod on a short non-retractable
strut, above and behind the cockpit. The landing gear is a rigidly-mounted
monowheel gear.
When it was available the aircraft was available as plans, a standard 600 hour build-time kit, an "express-built" kit or as a complete ready-to-fly aircraft. Prices in 1998 were US$325 for the plans, US$9,840 for the standard kit and US$15,250 for the completed aircraft. In 1998 22 were reportedly flying.
