The invention discloses an oil-drive variable-pitch quad-rotor unmanned aerial vehicle which comprises a power-transmission system, a rotor-operation system and a rack system. Both the rotor-operation system and the power-transmission system are fixed to the rack system. The oil-drive variable-pitch quad-rotor unmanned aerial vehicle mainly solves the problems that a conventional electric multi-rotor vehicle is poor in wind resistance and the like, the load is small, and the flight time is short and the problems that purchasing, using and maintaining cost is high and the use and maintenance technical doorsill is high due to complexity of the mechanical structure, the structural dynamic characteristic, the flight dynamic characteristic, the aerodynamic characteristic and a flight control system of a conventional helicopter.
