Abstract

The invention relates to a control rod for the adjusting of a helicopter rotor blade, wherein the control rod can be adjusted in longitudinal direction, comprising: at least one contact area element, at least one limit stop element, which is designed to limit the adjustability of the control rod in longitudinal direction to a specifiable adjusting range in interrelation with the at least one contact area element, wherein the limit stop element can be transferred from a first position to a second position, wherein the at least one stop element limits the adjustability of the control rod in the first position and enables the adjustability of the control rod beyond the specifiable adjusting range in the second position.
