This is an EDF model of NASA’s X-31 Enhanced Fighter Maneuverability Demonstrator, which flew in the early 1990’s. The X-31 had a thrust vectoring system that provided greatly improved post-stall and high alpha maneuvers. This model also features a thrust vectoring system, though I used vanes instead of paddles in the exhaust flow since they work better at model scale and are easier to build and set up. The X-31 park jet features simple foam construction similar to my other pusher prop park jets, and is very quick to build. In flight this model is very quick on the controls, but generally handles well and is fun to fly.
