The invention discloses a remote control device of a novel four-rotor unmanned aerial vehicle. For solving the problems that a traditional remote control device is large in control difficulty coefficient such as a US hand and a Japanese hand, a gyroscope and a magnetometer are added in a remote control device, the orientations of the orientation of the remote control device and the orientation ofthe vehicle head of the four-rotor unmanned aerial vehicle in the remote control device are synchronized, so that simple controlling of the flight direction and speed of the unmanned aerial vehicle through the inclined remote control device by an operator is realized, and the orientation of the vehicle head of the unmanned aerial vehicle does not need to be considered. The invention further discloses a using method of the remote control device, a hover switching button is designed, the possibility of misoperation of the remote control device is greatly reduced, and the safety performance is improved.
