Sonex Aircraft hopes to launch the first flight of its SubSonex single-engine jet as soon as acceptable weather breaks in Oshkosh, Wisconsin (the company’s home base). Its Czech-built PBS TJ-100 engine was first run on Dec. 23, 2009, and was able to hit 100 percent power — about 240 pounds of thrust. It’s larger than the radio-control-aircraft turbine that visitors saw mounted on the SubSonex during AirVenture this summer. For video of the engine runup, click here.
