Claim 13:
14. A cyclic pitch angle adjustment apparatus for a rotor with a rotor head and rotor blades that rotate around a rotor axis in a rotor plane, the cyclic pitch angle adjustment apparatus comprising:
a base point;
a bearing located in a central point positioned outside the rotor plane;
a first lever connected to a first rotor blade of the rotor blades to rotate the first rotor blade around a first pitch axis;
a second lever connected to a second rotor blade of the rotor blades to rotate the second rotor blade around a second pitch axis;
first and second rods mechanically linking the first and second levers with the bearing in the central point such that the first and second rods are movable relative to the central point, the first and second rods integrally formed as a single rod;
a connection connecting the first lever, the second lever, and the single rod with each other in a first location; and
a central rod disposed along a central rod axis that is parallel with the rotor axis, the central rod connecting the bearing with the base point and movable from along the central rod axis from a first position to a different second position and the central rod adapted to adjust the cyclic pitch angle of the first rotor blade and second rotor blade when the central rod is positioned in the first position to a first pitch angle and when the central rod is positioned in the second position to a second pitch angle that is different from the first pitch angle.
