The aircraft is supplied as a kit for amateur construction.

[1][2] The Superstol is a development of the Just Highlander and differs by the addition of automatic leading edge slats, a long stroke air shock robust landing gear with 29 in (74 cm) tundra tires, Fowler flaps and a newly designed tailplane.

The resulting design features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cockpit accessed by doors, fixed conventional landing gear and a single engine in tractor configuration.

[3][4] The aircraft fuselage is made from welded 4130 steel tubing, while the wing uses an aluminum spar and aluminum ribs, all covered in doped aircraft fabric.

The wings are supported by "V" struts with jury struts and can be folded for ground transportation or storage without the need for disconnecting fuel lines or control connections.
