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.

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 {{convert|8.40|ft|1|abbr=on}} span wing has an area of {{convert|9.00|m2|sqft|abbr=on}} and is equipped with flaps. The standard recommended engine is the {{convert|85|hp|kW|0|abbr=on}} Jabiru 2200 four-stroke powerplant.
