This is just a technology demonstration aircraft that does not possess basic air combat capabilities. Its appearance is solely for the purpose of validating my newly learned static instability layout and the new flight control system. everyone can just enjoy it for entertainment.Also, don't use it to perform any strange or unconventional flight maneuvers, and don't fly it to an altitude of 10,000 meters. If you do, the aircraft might behave very strangely...Of course, please don't ask me why this airplane doesn't have control over the yaw axis QAQ... (It wasn't done well, so I deleted it.)Feel free to make other modifications to my aircraft. If you can improve my flight control system, I would be very happy!
