1. A vibration attenuator, comprising:
a first spinner configured for rotation about a first axis;
a first mass coupled to the first spinner for rotation therewith, the first mass being movable radially relative to the first axis between an inner position and an outer position;
an actuator coupled to the first mass for selectively controlling a radial location of the first mass relative to the first axis;
a second spinner configured for rotation about a second axis;
a second mass coupled to the second spinner for rotation therewith, the second mass being movable radially relative to the second axis between an inner position and an outer position;
an actuator coupled to the second mass for selectively controlling a radial location of the second mass relative to the second axis; and
