The jet started as a pet project of Sonex founder John Monett who’s always wanted a personal jet. This thing is tiny, with a wingspan of just 18 feet and a maximum weight of 900 pounds. The itty-bitty jet engine produces 257 pounds of thrust.
Sonex is offering the SubSonex JSX-2 as a “ultra-quick build kit” with many major assemblies already completed. To comply with a Federal Aviation Administration rule requiring the owner to build at least 51 percent of a homebuilt airplane, the buyer will install the engine, fuel system, retractable landing gear, avionics and interior.
