25.4. Add flybar weights

You can slide a shaft collar onto both sides of the flybar. The shaft collars can be slid in or out from the head to adjust the cyclic sensitivity.

As the shaft collars are slid away from the head, this increases the inertia of the flybar and makes the cyclic less sensitive. Make sure the shaft collars are at the same distance from the center of the head to avoid unbalancing the flybar.
