The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 4500NaN0.

The aircraft has an empty weight of 1550NaN0 and a gross weight of 4050NaN0, giving a useful load of 2500NaN0. With full fuel of the payload is 2140NaN0.
