The MXS is a single-seat aerobatic aircraft made of carbon fiber and built by MX Aircraft Company, a manufacturer located at Jandakot Airport in Perth, Western Australia. The MXS-R is a race variant flown by several pilots in the Red Bull Air Race World Championship. The planes are all-composite in construction, piston-powered, low-wing monoplanes. They are produced both in kit form for amateur construction, and completed ready to fly at the factory.
