Robert Bushby acquired the rights to the Long Midget Mustang in 1959 and four years later began development of a two-seat, side-by-side version. This eventually flew in 1966 and plans were made available soon thereafter. Rights to both the Midget Mustang and the Mustang II were sold to Mustang Aeronautics in 1992. A single engine in tractor configuration airplane, the Mustang II features cantilever low-wing, two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed conventional landing gear, or, optionally, tricycle landing gear. The aircraft is made from riveted sheet aluminum with a rounded turtle deck and flat sides and bottom skins. Its 24.2 ft (7.4 m) span wing employs a NACA 64A212 airfoil at the wing root, transitioning to a NACA 64A210 at the wingtip. Standard engines used include the 150 to 160 hp (112 to 119 kW) Lycoming O-320, the 180 hp (134 kW) Lycoming O-360 and the fuel-injected 200 hp (149 kW) Lycoming IO-360 four-stroke powerplants. Standard fuel capacity is 25 US gallons, but optional wet wings increase the fuel capacity to 61 US gallons. Several other fuel tank options are available. A folding wing option may be installed.
