A three axis control system employing four flaps is disclosed. The flaps are of uniform design, which decreases machining and manufacturing costs. The flaps are positioned on a vehicle orthogonally, but offset from a vehicle centerline. The system provides not only pitch and yaw control, but also bi-directional roll control with a minimum number of parts and minimal infringement of packaging envelope. The system provides quick response and increased capability for difficult maneuvers and is useable for hypersonic/supersonic applications.
