The aircraft is supplied as a complete ready-to-fly-aircraft.<ref name="WDLA11">Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 206. WDLA UK, Lancaster UK, 2011. ISSN 1368-485X</ref>

==Design and development== The aircraft was designed to comply with the US [[FAR 103 Ultralight Vehicles]] rules, including the category's maximum empty weight of {{convert|115|kg|lb|0|abbr=on}}. It is German DULV certified and can be flown with any suitable [[Flying wires|cable-braced]] [[hang glider]] [[high-wing]]. The aircraft features weight-shift controls, a single-seat open cockpit, [[tricycle landing gear]] and a single engine in [[pusher configuration]]. The hang glider wing can be replaced with a [[paraglider]] wing and requires ten minutes to convert.<ref name="WDLA11" />

The aircraft is intended to be quickly folded into a package small enough to fit into a car for ground transport.<ref name="WDLA11" />

The aircraft is made from bolted-together [[aluminum]] tubing, with its single or double surface wing covered in [[Dacron]] sailcloth. A number of different hang glider and paraglider wings can be fitted to the basic carriage. A typical hang gider wing used would have a {{convert|9.5|m|ft|1|abbr=on}} span and would be supported by a single tube-type [[kingpost]] and use an "A" frame weight-shift control bar. The carriage front wheel is adjustable to allow for different pilot leg lengths.<ref name="WDLA11" />

The powerplant is a single cylinder, air-cooled, [[two-stroke]], {{convert|28|hp|kW|0|abbr=on}} [[Simonini Mini 2]] engine. Without the wing, the aircraft has an empty weight of {{convert|32|kg|lb|0|abbr=on}} and a gross weight of {{convert|200|kg|lb|0|abbr=on}}. The fuel tank holds {{convert|10|L}}.<ref name="WDLA11" />

An [[Electric aircraft|electric version]] was under development in 2011.<ref name="WDLA11" />
