PROBLEM TO BE SOLVED: To provide a simple and inexpensive solution for automatically stabilizing a helicopter. SOLUTION: A main rotor 4 has a rotor shaft 8 and propeller blades 12. An auxiliary rotor 5 has an oscillating shaft arranged orthogonal to the rotor shaft 8 and vanes 28 oscillating around the oscillating shaft 30. A mechanical link links the main rotor 4 to the auxiliary rotor 5 so that the oscillation of the auxiliary rotor 5 controls the angle of incidence of the blades 12 of the main rotor 4. A tail rotor 6 has a swing 22 oscillated around a swing shaft 21 extending in the longitudinal direction of a fuselage 2, a second rotor shaft 17 supported by the swing 22, and blades driven by the second rotor shaft 17.
