If you have an aileron gyro, it will reduce the roll effect , secondary effect of the yaw, very noticeable with swept wings , when you squeeze in some rudder to align the aircraft with the runway just before touchdown.
If you have a rudder gyro, it will damp the tendency of the machine to swing its nose into the crosswind during roll out !
