==Design and development== The aircraft was designed to comply with the [[Fédération Aéronautique Internationale]] [[microlight]] category, including the category's maximum gross weight of {{convert|450|kg|lb|0|abbr=on}}. The aircraft has a maximum gross weight of {{convert|361|kg|lb|0|abbr=on}}. It features a [[Flying wires|cable-braced]] [[hang glider]]-style [[high-wing]], weight-shift controls, a two-seats-in-[[tandem]] open cockpit with a [[cockpit fairing]], [[tricycle landing gear]] with [[wheel pants]] and a single engine in [[pusher configuration]].<ref name="Aerocrafter" />

The aircraft is made from bolted-together [[aluminum]] tubing, with a [[fibreglass]] cockpit fairing and its double surface wing covered in [[Dacron]] sailcloth. Its {{convert|10.6|m|ft|1|abbr=on}} span wing is supported by a single tube-type [[kingpost]], uses an "A" frame weight-shift control bar and has a wing area of {{convert|13.8|m2|sqft|abbr=on}}. The standard powerplant used is a twin cylinder, liquid-cooled, [[two-stroke]], [[dual-ignition]] {{convert|64|hp|kW|0|abbr=on}} [[Rotax 582]] engine. The aircraft has an empty weight of {{convert|160|kg|lb|0|abbr=on}} and a gross weight of {{convert|361|kg|lb|0|abbr=on}}, giving a useful load of {{convert|201|kg|lb|0|abbr=on}}. With full fuel of {{convert|42|L}} the payload is {{convert|171|kg|lb|0|abbr=on}}.<ref name="Aerocrafter" />
