Czech motorglider

TST-6 Duo General information Type Motor glider National origin Czech Republic Manufacturer TeST Status Production completed Number built 6 (1998)

The **TeST TST-6 Duo** is a [Czech](/source/Czech_Republic) [shoulder-wing](/source/Shoulder-wing), two-seats in [side-by-side configuration](/source/Side-by-side_configuration) [motor glider](/source/Motor_glider) that was designed and produced by [TeST](/source/TeST) of [Brno](/source/Brno).[1][2][3]

## Design and development

The TST-6 was designed as a two-place touring motorglider. Production is complete and the aircraft is no longer available.[1]

The TST-6 is of mixed wood and [fibreglass](/source/Fibreglass) construction. The 14.7 m (48.2 ft) span [forward-swept wings](/source/Forward-swept_wings) feature both top surface [air brakes](/source/Air_brake_(aircraft)) and [flaps](/source/Flap_(aircraft)) and employ a Wortmann FX 61-184 [airfoil](/source/Airfoil). The two occupants are housed in a 107 cm (42 in) wide [cockpit](/source/Cockpit), under a single piece [bubble canopy](/source/Bubble_canopy) that is rear-hinged and are provided with dual controls and adjustable rudder pedals. Both the wings and [tailplane](/source/Tailplane) are removable for transportation or storage. The [landing gear](/source/Landing_gear) is fixed [tricycle gear](/source/Tricycle_gear) and fits [wheel pants](/source/Wheel_pants). The standard engine provided was the custom M-215 of 37 kW (50 hp), although other similar engines of 37 to 63 kW (50 to 84 hp) can be fitted, including the 48 kW (64 hp) [Rotax 582](/source/Rotax_582). The engine is nose-mounted in [tractor configuration](/source/Tractor_configuration) and drives a three-bladed, ground adjustable, wooden-bladed propeller.[1][4]

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$](/source/US%24)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.[1][3]
