This butterfly ornithopter material is made of imported high-strength and impact-resistant materials. After repeated tests, the durability is much better than that of carbon fiber. After years of exploration, we finally developed a mature product, and the accessories on the whole machine were upgraded to aviation aluminum. The structural parts of the fuselage were designed to make the products more wear-resistant. This butterfly ornithopter is very stable and easy to operate in flight and has high safety. Apply some lubricant to the ball head on the rocker before flying.
