Developed by LGAA and its partners, the RX1E could be used for pilot training, sightseeing and aerial photography.

The plane is environmentally friendly and has many advantages compared with gasoline-fueled ones. "It's pollution-free, quiet and easy to pilot," Zhao said.

It took two-and-a-half years of intense work to develop the aircraft.

According to Gu Chao, one of the designers, the core problem is how to control the weight of the plane.

Finally, the R&D team found the way by using all-composite materials and improving the motor efficiency to 94 percent, which helped increase the operation rate of the lithium battery.
