The invention discloses an odd rotor wing unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles. The odd rotor wing unmanned aerial vehicle comprises a flight controlsystem, a frame, a battery, a motor, an electronic speed controller, a paddle, a remote controller, a universal rotor wing and even number balance rotor wing sets; the flight control system realizesmovement in all directions and at different speeds through control over the universal rotor wing set; motor sets of the even number balance rotor wing sets in the same plane are adjusted in rotating speed under the effect of the flight control system, and therefore the whole unmanned aerial vehicle is kept balanced; the remote controller controls the rotating direction and the rotating speed of the universal rotor wing set, and does not control the rotating speed of the motor sets of the balance rotor wing sets. The cruising ability and flexibility of the unmanned aerial vehicle are improved,and the practicability and convenience of the unmanned aerial vehicle are improved.
