to a tractor-tail rotor configuration as this configuration has increased yaw authority from the upwards advancing tail rotor blades into the downwash. The increase of the airspeed flowing over the rotor blades increases overall tail rotor effectiveness and yaw authority, whereas with the 'Pusher' tail rotor configuration the advancing rotor blade moves downwards. This decreases the airspeed across the rotor blade, reducing its overall effective yaw authority.
