Flybar
From RC Helicopter Wiki
A component of the helicopter's main rotor system that acts to stabilize that system and make it more controllable. Used on two-bladed main rotors only, the flybar is a metal rod that is mounted perpendicular to the main blades, and either above or below them, with a short airfoil (or paddle) on each end. The flybar passes through the mast-mounted "seesaw" and through the linkages attached to it, is responsible for the pitch changes imparted to the main rotor blades. It does this by converting aerodynamic forces from the spinning airfoils into angular forces which act on the main rotor blade grips. The flybar also employs both angular momentum and aerodynamic force to help stabilize the main rotor blades. Newer electronic stabilization systems which allow the elimination of the flybar are becoming more affordable.
