The present invention provides a drone comprising: a drone body; main rotors generating a driving force; sub-rotors generating a driving force instead of the main rotor above and below the main rotor, respectively; connection frames connecting the sub-rotors to the drone body above and below the main rotor, respectively; a detector detecting failure of the main rotors; and a controller controlling the sub-rotors to generate a driving force when detecting failure of the main rotor, wherein the connection frame is rotatably connected to the drone body, rotates, and moves the sub-rotor; wherein each connection frame comprises a rotation frame protruded upward or downward from the drone body and rotatably connected to the drone body; a horizontal frame horizontally connecting the sub-rotor to the rotation frame, and a balance weight protruded from the rotation frame in an opposite direction to the horizontal frame.
