Backcountry Super Cubs Mackey SQ2

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.

Design and development
The Mackey SQ2 features a strut-braced high-wing, a two-seats-in-tandem enclosed cockpit that is 30 in wide, fixed conventional landing gear and a single engine in tractor configuration.

The aircraft fuselage is made from welded steel tubing, with the wings constructed of aluminum sheet, all covered in doped aircraft fabric. Its 36.9 ft span wing has an area of 170 sqft, 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 180 to 240 hp and standard engines used include the 180 hp 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.
