The invention discloses a variable-propeller-pitch multi-rotor aircraft driven by multiple oil engines. The multi-rotor aircraft comprises an aircraft body and an aircraft rack, wherein the aircraft rack is mounted on the aircraft body; the aircraft rack comprises four aircraft arms and oil-engine power units; the aircraft rack is in a cross shape and formed by two pairs of the aircraft arms in abutting connection; each oil-engine power unit is mounted at the end part of the corresponding aircraft arm; the aircraft body comprises an upper center plate, a lower center plate, an oil tank and a control system; the upper center plate is positioned on the cross-shaped aircraft rack; the lower center plate is positioned under the cross-shaped aircraft rack; the control system is positioned on the upper center plate; the oil tank is positioned under the lower center plate. The multi-rotor aircraft disclosed by the invention has the benefits that through a structure driven by multiple oil engines, the time of endurance of the multi-rotor aircraft is prolonged, and the loading capacity of the multi-rotor aircraft is improved; throttles are regulated through steering engines and propeller-pitch regulators, so that the tensile force is changed along with propeller pitch; the multi-rotor aircraft is good in linearity, and easy to control, and solves the problem that the reaction of oil engines is slow.
