According to the company, "Following a series of initial high-speed taxi tests, the Sonex Aircraft Hornets' Nest Research and Development team determined that a review and modification of the aircraft design was necessary to achieve acceptable handling qualities for the average pilot. Due to the increased power offered by the new PBS TJ-100 engine selected for the SubSonex, it was determined that a tricycle gear configuration would be needed to increase yaw stability on the ground in the transition phase approaching takeoff speeds."
The single-seat jet has a 750-pound maximum gross weight, is said to weigh 330 pounds empty. The engine has up to 200 pounds of thrust. It has 60 square feet of wing.
