TBS Quadcopter

A quadcopter, sometimes known as a quadrotor, is a helicopter with four rotors. Despite the fact that quadrotor helicopters and convertiplanes have been flown in the past, the arrangement remained a mystery until the modern UAV or drone arrived. Drones' tiny size and low inertia allow for a very simple flight control system, considerably increasing the usefulness of the small quadrotor in this application.
