In its neutral or undeflected position each arm extends radially inward from the respective pivot and the control surface it carries, which is generally in the form of a circular arc centered on the pivot, lies retracted wholly within the housing. Angular movement of each arm about its pivot in one direction or the other causes one or the other half of the respective control surface to project from the housing. Different combinations of movement of the several control surfaces give rise to moments in roll, pitch or yaw. | |
