Development and design
The TST-14J is a Desert Aerospace, LLC modification of the TST-14 motorglider with the addition of a retractable jet engine used for self launching. It has a high T-tail. It is a mid wing design with straight tapered wings. The wing tips carry winglets and there are outboard ailerons, two position flaps and upper surface spoilers.{{cite web|title=Desert Aerospace|url=http://www.desertaerospace.com/bonusjet/bonus_info.html|accessdate=13 August 2011}}
The fuselage of the TST-14J is built from two half shells which incorporate the straight tapered fin. The fuselage tapers rearwards, producing an arched shape below. The tailplane carries a single piece elevator. The cockpit has a forward hinged, single piece canopy, and a side hinged passenger canopy. The TST-14J has a tailwheel undercarriage, with spatted mainwheels on fuselage-mounted, sprung, cantilever legs.
The 45 lb PBS TJ-100 turbine engine {{Cite web|title=TST-14J BonusJet|url=http://www.switched.com/2010/08/10/tst-14j-bonusjet-comes-with-retractable-jet-engine/|accessdate=13 August 2011}} requires a two-minute cooldown before retracting into the fuselage. The prototype was tested by Bob Carlton, an experienced jet powered glider pilot who flies an aerobatic routine in a Super Salto jet powered glider with the same engine.{{cite web|title=Jet Powered glider tested|url=http://www.aopa.org/aircraft/articles/2010/100607desertaerospace.html|accessdate=13 August 2011}} Sonex Aircraft also uses the same engine, and hired Carlton to test its SubSonex jet-powered homebuilt aircraft.
