Stick Shake

Stick shake can indicate an imbalance in the rotor blades, the hub bar to the teeter tower or a worn teeter bolt.  

As the blades spin, the centre of gravity of the rotor disc does not pass through or close to the axis of rotation.

Any variations in weight and distribution of that weight across the blades would have been eliminated at the factory.
