Design and development
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.
The TST-3 is of mixed construction, using fibreglass, wood and aircraft fabric covering. The {{convert|13.4|m|ft|1|abbr=on}} span wing is equipped with winglets and a Wortmann FX 61-184 airfoil. The tractor configuration Hirth F-33 {{convert|16|kW|0|abbr=on}} 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 {{convert|37|kW|0|abbr=on}} was optional. The landing gear is retractable monowheel gear.{{Cite web|url = http://www.ae.illinois.edu/m-selig/ads/aircraft.html|title = The Incomplete Guide to Airfoil Usage|accessdate = 9 September 2011|last = Lednicer|first = David|authorlink = |year = 2010|archive-date = 20 April 2010|archive-url = https://web.archive.org/web/20100420012244/http://www.ae.illinois.edu/m-selig/ads/aircraft.html|url-status = dead}}
