6. A system to prevent or limit resonance in a rotocraft, the system comprising:
an airframe including an attachment fitting with a slot formed therein and having a longitudinal axis;
a rotor system having a natural frequency and including a rotor and a mast, the rotor system and the airframe operable to move relative to each other as the rotor system begins to oscillate; and
an attachment mechanism connecting the airframe and the rotor system, being operable to prevent or limit resonance in the rotocraft, and including a shuttle having a first end and a second, opposing end connected to the mast with the shuttle being received in the slot of the attachment fitting such that the shuttle is operable to move generally along the longitudinal axis of the slot.
