  • Single rotor model helicopter with improved stability behavior
    Patent number: 8177600
    Abstract: A single rotor model helicopter is provided, comprising a spindle, a rotor clamp disposed on the spindle, a pair of rotor blades disposed on the rotor clamp, and a pair of hybrid control rocker arms. The helicopter further includes an operating system and a balancing system. The pair of hybrid control rocker arms are disposed on both sides of the rotor clamp respectively and rotatably connected to a pitch control rocker arm through each axial hole located on a center of each hybrid control rocker arm, so as to control attack angles of the rotor blades. Each hybrid control rocker arm has two control points. A first pair of control points diagonally opposite each other in the pair of hybrid control rocker arms are controlled by a cyclic torque transmitted from the operating system, and a second pair of control points diagonally opposite each other are controlled by the balancing system.
