The invention provides a super-miniature fuel oil unmanned helicopter. A propeller connecting structure of the helicopter, particularly a main rotor and a tail rotor, can be innovated, an engine power transfer structure of the fuel oil unmanned helicopter is innovated and improved, a clutch type power output technology and a reduction and differential power transfer structure are introduced, the transmission ratio can be dynamically adjusted according to the rotating speed of an engine, and the power transfer process of the unmanned helicopter is stabilized to the greatest degree. Meanwhile, the structure of the turbo charger of an engine is improved, power of the unmanned helicopter is guaranteed, the power transfer of the engine and the rotating process of a propeller are stabilized under the condition that the engine output power is improved, and conditions are created for reducing the size of the fuel oil unmanned helicopter, so that the super-miniature fuel oil unmanned helicopter of which the body length is 1m or below is innovated at the first time, and the unmanned helicopter has wide market application prospects.
