Mast Rock is caused by low rotor RPM and rotor head dampening.  This visible shaking or rocking motion is visible arount the rotor mast as rotor RPM is lowered.  This natural rocking motion is caused by the rotor head dampeners not providing sufficent dampening at given main rotor RPM. If the dampeners are soft, then the effect will occur at a lower RPM.  If the dampeners are hard (such as 3D), then the rocking motion will occurr at a much higher RPM.  You can avoid this motion by simply raising the main rotor RPM.
