Design and development edit
The TST-3 was produced in many forms, including as plans and kits or various levels of completion for amateur construction and also as a factory completed aircraft. 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]
Two were reported to have been completed by December 2000. In December 1998 the glider version was US$13,000. In December 2000 the kit was US$10,000, complete aircraft US$23,300 and the plans US$350. In 2004 the complete aircraft was €22,880.[1][2][3]
