Abstract
A pitch control system for blades on a rotor of an aircraft has a gimballing rotor hub () and a plurality of step-over arms () connected to the hub and capable of pivoting relative to the hub about a pivot axis. Each of a plurality of pitch links () connects one of the step-over arms () to a flight control system for pivoting the connected step-over arm () about the pivot axis and relative to the hub in response to inputs from the control system. Each of a plurality of step-over links () connects one of the step-over arms () to one of the blades for rotating the associated blade about the pitch axis in response to pivoting of the associated step-over arm.
