A quadcopter, also called quadrocopter, or quadrotor[1] is a type of helicopter or multicopter that has four rotors.[2]
Although quadrotor helicopters and convertiplanes have long been flown experimentally, the configuration remained a curiosity until the arrival of the modern unmanned aerial vehicle or drone. The small size and low inertia of drones allows use of a particularly simple flight control system, which has greatly increased the practicality of the small quadrotor in this application.
