Zusammenfassung:The invention is related to a control system 10 for controlling at least collective pitch of rotor blades 1b, 1c of a multi-blade rotor la with a rotor shaft le in a rotary-wing aircraft 1, said control system 10 comprising a non-rotating sliding sleeve 13 that is mountable to the rotor shaft le such that the non-rotating sliding sleeve 13 is axially displaceable coaxially to an associated rotor axis 1f on the rotor shaft 1e, at least one actuator arm 20b that is pivotally mounted to the non-rotating sliding sleeve 13 and adapted for axially displacing the non-rotating sliding sleeve 13 that is mounted to the rotor shaft 1e upon activation, and at least one hinge support 21 that is adapted for a hinged support of the at least one actuator arm 20b.
