Many flight mode's oil moves many rotor crafts of displacement

Many flight mode's oil moves many rotor crafts of displacement aircraft field. Expect much to the place of taking off and land for solving current fixed wing aircraft, many rotor crafts flying speed is immutable, and the poor problem of rotor craft flexibility designs. It includes the fuselage, and battery and flight controller adorn in the fuselage, and the horn is connected with the fuselage through servo steering wheel, has lift board, engine, oil tank on the horn, has screw actuating mechanism on the engine, screw mechanism includes the main shaft, and even, the rotor head is fixed on the main shaft between main shaft lower extreme and the engine power output shaft, and rotor head and rotor ally oneself with, and the displacement axle in the main shaft is fixed with displacement bearing inner race, and displacement bearing inner race is connected with the servo steering wheel of displacement control, and the servo steering wheel of displacement control is fixed on the engine, and there is the displacement shift fork in displacement crown of roll portion, and the upper end and the displacement shift fork of displacement pull rod are connected, and the lower extreme presss from both sides with the rotor to be connected. The advantage is that flight mode is adjustable, and the flying speed is adjustable, saves fuel consumption.
