The closest current wings from other brands — every one within ±5% of area and ±8% of aspect ratio, ranked closest first. The closest, the GONG Ypra Slalom V3 Atmo S, is already drawn over it. Select a numbered wing to draw it — up to three at a time.
The Free Series runs 4 sizes, 540–900 cm², and changes proportion as it grows: aspect ratio runs 8.4 at one end of the range to 13.3 at the other, so its sizes differ in shape as well as in area.
Its 770 mm span is typical for the area: the median across the 102 current wings within 10% of its size is 780 mm.
Projected and flat area run 3–8% apart. A marked area is one whose brand does not state which it publishes, so a comparison inside the area tolerance may be comparing unlike figures.
