No, no, no, Mr Torque;
The moths in a helicopter pilot's wallet lighten the load and make it easier to fly!
The design of rotor heads other than the 47/204/205 is such that they don't need stabilisation. Sure, the R22 is twitchy, but twitchy=responsive. Stable = slow response to inputs. Fighter planes are twitchy, Cessnas and upwards are stable.
