Design and development

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.[1] It is designed for operation on rough airfields.[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. Standard engines available include the 80 hp (60 kW) Rotax 912UL, the 100 hp (75 kW) Rotax 912ULS or Rotax 912iS, the 115 hp (86 kW) Rotax 914, 85 hp (63 kW) Jabiru 2200, the 120 hp (89 kW) Jabiru 3300 and the 80 hp (60 kW) Volkswagen air-cooled engine, four-stroke powerplants. The aircraft can take-off and land in under 150 ft (46 m)[1][4][5]
