[1][2][3] The TST-14 motor glider was designed for private owner and flying school use and as such features wing tip wheels that allow independent taxiing and take-off.

The TST-14 is constructed of composite materials, mainly epoxy resin and fiberglass with a sandwich structure and transverse ribs.They are also present with a few parts in wood, carbon fiber and aluminium.

Therefore, like all two-seaters, the pilot must sit in the front seat and weigh between 75 and 100 kg.If he exceeds these weights, it will be necessary to add or remove ballast, which is placed at the tip of the glider on two special plates.

The motor glider version is powered by a retractable 50 hp (37 kW) Rotax 503UL two-stroke engine and a 120cm wooden propeller.The engine is equipped with cylinder head temperature (CHT) sensors, and despite being installed in an upside down position, the temperature never causes concern during take-offs with maximum and prolonged power.

Landing, if necessary, can take place in approximately 150 m The aircraft was type certified to the Joint Aviation Authorities JAR 22 standard for gliders on 10 Dec 2001.
