Stabilizer Bar Operation:
The stabilizer bar is connected into the flight system in such a manner that the inherent inertia and gyroscopic action are induced into the rotor system to provide a measure of stability for all flight conditions. If, while hovering, the helicopter's attitude is disturbed, the bar tends to remain in its present plane. The relative movement between the bar and the mast will cause the blades to feather and return the rotor to its original plane of rotation. When the rotor disc is displaced by cyclic action, initially a portion of the cyclic movement is removed, but because of pendulum action of the helicopter, the mast is displaced. Now, because of the restraining and damping action of the dampers, the bar possesses a mast-following characteristic. The time it requires the bar to follow the mast and return all the cyclic control to the rotor is determined by damper timing (5 ± 1 second). A compromise between gyroscopic action and damper timing is maintained during flight which allows the bar to provide a measure of stability, yet still affords the pilot complete control of the helicopter.

Them lil Dampers wuz critical components. they kept the pilots sweat down and his pants clean.
