The JSX-1 is a single place, single engine jet aircraft similar in design to an Onex, with a Waiex style Y tail, fixed main landing gear and a retractable nosewheel. Introduced at AirVenture 2009, it is powered by a Czech-built PBS TJ100 turbojet engine mounted above the aft fuselage, with the exhaust exiting between the Y-tail. It achieved first engine test runs in December 2009. The engine produces 1100 N (240 lb) of thrust. Originally developed with only a central mono pod wheel, tail wheel and small wing tip outriggers, the prototype exhibited directional controllability problems during taxi tests.[citation needed] It was flight tested by jet-sailplane performer Bob Carlton in August 2011.[1][2]
The production model of the SubSonex is the JSX-2. The landing gear was changed to a fully retractable, pneumatically-operated tricycle configuration.[3][4][5][6]
At AirVenture 2013 the company began taking US$10,000 deposits on production kits. The kit's projected price was US$125,000 in 2013 and US$135,000 in 2014.[2][7]
The first JSX-2 kit was shipped to a customer in February 2015,[8][9] and completed and flown in October 2015.[10]
Second version with a BRS parachute, wider fuselage, more streamlined nose, and fully retractable undercarriage.[18] Bob Carlton performed the first test flight with the prototype JSX-2 on 10 July 2014 from Wittman Field.[19] Entered production as an amateur-built kit in the fall of 2014.[20][21]
JSX-2T
Two-seats in side-by-side configuration version announced in July 2019. It will use the same PBS TJ-100 turbojet engine with the PBS TJ-150 as an option. The design is projected to offer a cruise speed of over 174 kn (322 km/h) and an estimated useful load of 970 lb (440 kg).[22] The aircraft was expected to be first publicly displayed at Airventure in July 2020, but the event was cancelled due to the COVID-19 pandemic.[23][24]
