During WWII, semi-tailless aircraft were studied by engineers in the U. S. and UK after the Luftwaffe deployed the Me-163. Post-war, Northrop built and tested the X-4 to assess its performance at near-supersonic speeds. The NACA took over the X-4 program from Northrop in 1950. High-speed instability led to the conclusion that semi-tailless aircraft were unsuitable for transonic flight. The X-4 on now display in the National Museum of the USAF in Dayton OH (which I’ve been to many times).

  Takeoff should be achieved at 50% throttle. But rudder left slightly to keep you on course. You can use the gyroscope to help you takeoff and land.
