It was produced as a motor glider with a retractable engine and also as a pure glider. Production is complete and the type is no longer available.^[1]

The TST-3 is of mixed construction, using fibreglass, wood and aircraft fabric covering. The 13.4 m (44.0 ft) span wing is equipped with winglets and a Wortmann FX 61-184 airfoil. The tractor configuration Hirth F-33 16 kW (21 hp) motor is mounted on a strut that retracts aft into a bay behind the cockpit and is enclosed by two doors. A Rotax 503 of 37 kW (50 hp) was optional. The landing gear is retractable monowheel gear.^[1][3][4]
