English: A quadrotor yaws in the anticlockwise direction by applying more thrust to the two clockwise rotors than the two anticlockwise rotors. A conservation of angular momentum causes the quadrotor to rotate as desired. In this diagram, the thickness of the arrows indicate the relative amount of thrust applied.

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.
Linkages (silver) to the rotor blade In aeronautics , a swashplate is a mechanical device that translates input via the helicopter flight controls into motion of the main rotor blades . Because the main rotor blades are spinning, the swashplate is used to transmit three of the pilot's commands from the non-rotating fuselage to the rotating ...

For a given weight, a helicopter with shorter rotors will have higher disk loading, and will require more engine power to hover. A low disk loading improves autorotation performance in rotorcraft. [5] [6] Typically, an autogyro (or gyroplane) has a lower rotor disk loading than a helicopter, which provides a slower rate of descent in ...
It was not a free flight, as four men were used to steady the structure. It was neither controllable nor steerable, but it was the first time that a rotary-wing device had lifted itself and a pilot into the air. [1] It later flew up to 1.52 m (4.99 ft) above the ground. The design was improved and the Gyroplane No.II appeared the following year ...
One rotor. Powered rotors require compensation for the torque reaction causing yaw, except in the case of tipjet drive. One rotor rotorcraft are typically called monocopters. Two rotors. These typically rotate in opposite directions cancelling the torque reaction so that no tail rotor or other yaw stabiliser is needed. These rotors can be laid ...
