The closest current wings from other brands — every one within ±5% of area and ±8% of aspect ratio, ranked closest first. The closest with a traced outline, the RRD Universal Moonfish Front Wing Y30 1900 (#2), is already drawn over it. Select a numbered wing to draw it — up to three at a time.
The APF runs 3 sizes, 1,350–1,880 cm², and changes proportion as it grows: aspect ratio runs 8.6 at one end of the range to 10.7 at the other, so its sizes differ in shape as well as in area.
Its 1,302 mm span is typical for the area: the median across the 60 current wings within 10% of its size is 1,300 mm.
Closest wings from other brands
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.
