27.3. Shorter flybar increases cyclic response

Imagine a flybar so short the paddles touch the head. With this length flybar, the paddles will be traveling in a small circle and have very little airspeed, so they will not exert much force to change the main rotor blade pitch.

Also, since the flybar is so short, the paddles will also have less leverage against the main rotor blades and will exert even less force to change the main rotor blade pitch.

Therefore, a longer flybar increases the cyclic response, not a shorter flybar.
