Design and development
The TST-7 Junior was a development of the
TST-1 Alpine self-launching sailplane, with a design goal of producing an aircraft more suited for use as a touring motor glider with docile handling.
The TST-7 is built from wood, with some
fibreglass parts. The span, shoulder-mounted, slightly

A forward-swept wing is an aircraft wing configuration in which the quarter-chord line of the wing has a forward sweep. Typically, the leading edge also sweeps forward.
Characteristics
The forward-swept configuration has a number of character ...

The aircraft was supplied as a ''standard kit'' rated at 400 hours for completion and that did not include the powerplant. An ''Express-Build'' kit was also available that could be completed in 250 hours. The factory also built some TST-7s as ready-to-fly models that were
