It's a German style fictional aircraft, and I've probably released the last version of it - it used a dangerous, unreliable, uncontrollable rocket engine. Now that's changed. I've built two controllable, safe, and efficient rocket engines - of course, the me695 light fighter uses a new moon 1 rocket engine (that is my code name,,,) when you press 1 to start the engine, there will be two rings of exhaust gas on the surface of the engine, which is safe and normal. You just need to push the throttle valve You can fly the plane safely in any condition, which is different from some controllable rocket engines which can only run in high physics or medium physics. Have a pleasant time
