RC quadcopter, also called a quadrotor helicopter or quadrotor, is a multirotor helicopter that is lifted and propelled by four rotors.

Quadcopters generally use two pairs of identical fixed pitched propellers: two clockwise (CW) and two counter-clockwise (CCW) in a cross-shape layout. These use independent variation of the speed of each rotor to achieve control. By changing the speed of each rotor, it is possible to specifically generate a desired total thrust and to create a desired total torque, or turning force.

Because of its inherent complexity, there has never been a large-scale commercial quadcopter in history. In recent years, thanks to the development of MEMS (micro electro mechanical system), fixed propeller quadcopter has been widely concerned, and its application prospect is considerable.

There are four well-known quadcopter aircraft company internationally, China's DJI, France Parrot, Germany AscTec and the United States 3D Robotics.
