A cyclic pitch angle adjustment apparatus for a rotor or propeller and to a rotorcraft with such a rotor. The cyclic pitch angle adjustment apparatus may include levers that rotate rotor blades around associated pitch axes rods that mechanically link the levers with a bearing such that the rods are movable relative to the central point, the bearing being attached to a central rod that is movable and adapted for adjusting the cyclic pitch angle of the rotor blades from one pitch angle in one position to another pitch angle in another position.
