This is a brand new flapping wing aircraft. It is unique that he flies in the air by shaking his wings. But that means he also has some design flaws. He was completely unable to adapt to high-speed flight, and needed to be put at a high altitude.If you want to use it conveniently, I'd like to ask you to save a birth point in the air at a speed of about 200 and drop the plane. In general, its maximum flight speed is 110. The gyroscope will let it increase its height automatically. If you want to accelerate, you need to dive.I don't know why this plane will fail in low speed mode, and may crash in the worst case. I try to keep the structure of the plane as simple as possible so that it can adapt to both low and high physical modes.If you think the plane is doing well, I hope you will give me your support. If you have any other questions during the use, you can ask me in the comment area.
