The Backcountry Super Cubs Mackey SQ2 is an American STOL amateur-built aircraft, designed and produced by Backcountry Super Cubs of Douglas, Wyoming. The aircraft is based upon the design of the Piper PA-18 Super Cub and is supplied as a kit for amateur construction.[1] Design and developmentThe Mackey SQ2 features a strut-braced high-wing, a two-seats-in-tandem enclosed cockpit that is {{convert|30|in|cm|0|abbr=on}} wide, fixed conventional landing gear and a single engine in tractor configuration.[1] The aircraft fuselage is made from welded steel tubing, with the wings constructed of aluminum sheet, all covered in doped aircraft fabric. Its {{convert|36.9|ft|m|1|abbr=on}} span wing has an area of {{convert|170|sqft|m2|abbr=on}}, is supported by "V" struts with jury struts and mounts flaps as well as leading edge slats. The aircraft's recommended engine power range is {{convert|180|to|240|hp|kW|0|abbr=on}} and standard engines used include the {{convert|180|hp|kW|0|abbr=on}} Lycoming O-360 four-stroke powerplant. The aircraft can be fitted with tundra tires for operations on soft or rough surfaces. Construction time from the supplied kit is 1200 hours.[1] Operational historyBy December 2011 seven examples had been reported as completed and flown.[1] Specifications (Mackey SQ2) {{Aircraft specs
