The invention provides a vertical take-off and landing fixed-wing unmanned aerial vehicle propeller drag reduction device and a control method thereof. The device is characterized in that the device comprises a vertical take-off and landing propeller, a linear Hall motor position sensing unit, a motor driving unit, an operation processing unit and a wind speed sensor unit; the operation processing unit outputs an adjustment instruction obtained after calculation and analysis to the linear Hall motor position sensing unit according to the received sensing result value, and finally the rotor resistance generated in the flight of the vertical take-off and landing fixed-wing unmanned aerial vehicle is reduced. According to the invention, the minimization of the wind resistance of the rotor wings in the cruise state in all time periods can be realized, so the energy consumption is greatly reduced, and the overall endurance time of the unmanned aerial vehicle is prolonged; the calculation method is simple and convenient, the structural design is scientific and reasonable, PID control is very easy to realize, and the overall structural complexity of the unmanned aerial vehicle is reduced; and the PID scheme is timely in response, so that later maintenance and management are facilitated.
