Design and development
The Sky Walker II is very different from the company's Sky Walker I and 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|400|kg|lb|0|abbr=on}}. It features a {{convert|50|m2|sqft|abbr=on}} parachute-style wing, two-seats-in-side-by-side configuration, tricycle landing gear and a single {{convert|60|hp|kW|0|abbr=on}} Bilsam TNA 625 four stroke engine in pusher configuration.
The aircraft carriage is built from a combination of composite material and steel tubing. In flight steering is accomplished via foot pedals that actuate the canopy brakes, creating roll and yaw. Unusually for this class of aircraft, the Sky Walker II has an enclosed cockpit. A variety of wings can be fitted.
The aircraft has an empty weight of {{convert|155|kg|lb|0|abbr=on}} and a gross weight of {{convert|400|kg|lb|0|abbr=on}}, giving a useful load of {{convert|245|kg|lb|0|abbr=on}}. With full fuel of {{convert|40|L}} the payload for crew and baggage is {{convert|216|kg|lb|0|abbr=on}}.
