Design and development

The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear and a single engine in tractor configuration.[1][2]

The aircraft is made from sheet aluminum with its windshield made from a single piece of flat plastic to save money on construction costs. Access to the cockpit is via gull-winged doors. Its 8.40 ft (2.6 m) span wing has an area of 9.00 m² (96.9 sq ft) and is equipped with flaps. The standard recommended engine is the 85 hp (63 kW) Jabiru 2200 four-stroke powerplant.[1][2]
