The only thing weird about the f117's all moving rudder is that the joint is placed halfway the rudder surface instead of the very root, and that's because the twin tails are placed too close to one another to allow any movement from the root like in the a-5 here, the axis of rotation is still perpendicular to the airflow like in a wright flier. The xb-70 put it in an oblique angle because apparently that would work better at supersonic speeds.
