The world's first helicopter that can fly backward at 20 kilometers per hour has appeared at the ongoing China International Import Expo (CIIE).
Developed by German company RotorSchmiede, the helicopter features dual coaxial main rotors that make it quieter, safer and more flexible.
The company is making its debut at the CIIE. Apart from the engines, the other parts of its helicopters are manufactured fully in China.
