Sonex Aircraft SubSonex


The SubSonex is an experimental, single-place, amateur-built jet from Sonex Aircraft's "Hornet's Nest" development division. The aircraft is often referred to in the industry as a "microjet".

Design and development

The JSX-1 is a single place, single engine, jet aircraft similar in design to an Onex, with a Waiex style Y tail. It was introduced at AirVenture 2009. It is powered by a Czech-built PBS TJ-100 turbojet engine mounted above the aft fuselage, with the exhaust exiting between the Y-tail. The SubSonex achieved first engine test runs in December 2009. The engine produces 1100 N 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.
The production model of the SubSonex is the JSX-2. The landing gear was changed to a tricycle configuration with a manually retractable nosewheel. It was flight tested by Jet-sailplane performer Bob Carlton in August 2011.
At AirVenture 2013 the company began taking US$10,000 deposits on production kits. The projected price of the kit was US$125,000 in 2013 and US$135,000 in 2014.
The first JSX-2 kit was shipped to a customer in February 2015 and was completed and flown in October 2015.
