The flybar acts as a "damper" on the rotorblades, and reduces the rate of
response to something that human reactions can cope with.

Without some kind of "rate reducer", the response rate of the rotor disc
is
so fast that it would have re-acted to your control inputs and crashed
before you even realised what had happened!

By mechanically linking the rotor disk to the flybar, the whole assembly
can
only move at the rate of the slowest reacting component - in this case the
flybar (be it Bell, Hiller or a combination of the two).

It is often referred to as a gyroscopic stabiliser, but this isn't
strictly
correct. A system doesn't have to be stable to be flyable, provided it
only
diverges slowly enough for a human pilot to react.

The gyro on the tail rotor performs a similar function.
