==Design and development== The TST-6 was designed as a two-place touring motorglider. Production is complete and the aircraft is no longer available.<ref name="Aerocrafter" />
The TST-6 is of mixed wood and [[fibreglass]] construction. The {{convert|14.7|m|ft|1|abbr=on}} span [[forward-swept wings]] feature both top surface [[Air brake (aircraft)|air brakes]] and [[Flap (aircraft)|flaps]] and employ a Wortmann FX 61-184 [[airfoil]]. The two occupants are housed in a {{convert|107|cm|in|0|abbr=on}} wide [[cockpit]], under a single piece [[bubble canopy]] that is rear-hinged and are provided with dual controls and adjustable rudder pedals. Both the wings and [[tailplane]] are removable for transportation or storage. The [[landing gear]] is fixed [[tricycle gear]] and fits [[wheel pants]]. The standard engine provided was the custom M-215 of {{convert|37|kW|hp|0|abbr=on}}, although other similar engines of {{convert|37|to|63|kW|hp|0|abbr=on}} can be fitted, including the {{convert|48|kW|hp|0|abbr=on}} [[Rotax 582]]. The engine is nose-mounted in [[tractor configuration]] and drives a three-bladed, ground adjustable, wooden-bladed propeller.<ref name="Aerocrafter" /><ref name="Incomplete">{{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}}</ref>
The aircraft was available as plans, a standard 400 hour construction kit, a 300-hour construction "Express-Built" kit or as factory-completed and ready-to-fly. In 1998, the factory-completed aircraft, less engine, was [[US$]]18,000. In December 2000, the complete aircraft with Rotax 582 powerplant was US$29,500, the aircraft without engine was US$21,200 and plans were US$350.<ref name="Aerocrafter" /><ref name="KitplanesDec2000" /> ==Specifications (TST-6) == {{Aircraft specs |ref=Purdy<ref name="Aerocrafter" /> |prime units?=met<!-- imp or kts first for US aircraft, and UK aircraft pre-metrification, met(ric) first for all others.
