 Because the vertical fin was only slightly shorter than the length of each wing and nearly as aerodynamically effective, it could act as a wing-on-rudder application, rolling the aircraft in the opposite direction of rudder input.To offset this effect, the wings were canted downward at a 10° negative-dihedral (anhedral) angle.This downward canting also had the effect of improving roll control during high-g maneuvers commonly used in air-to-air combat.
