Advantages and disadvantages of quadcopter

1. High flexibility, easy to maneuver

2. Almost no requirements for take-off and landing sites

3. Simple maintenance, not easy to be damaged, low cost

Disadvantages:

The flight control system is complex, unlike fixed-wing airplanes, which can be controlled by RC with rudders and receivers, quadcopters need to be tuned to the flight control, or to write the program, and the flight control electronics are more complex.
