The closest current wings from other brands — every one within ±5% of area and ±8% of aspect ratio, ranked closest first. The closest, the Takoon Flare Front Wing 650, is already drawn over it. Select a numbered wing to draw it — up to three at a time.
The Razor Blackbird runs 4 sizes, 648–1,069 cm², and changes proportion as it grows: aspect ratio runs 8.4 at one end of the range to 11.0 at the other, so its sizes differ in shape as well as in area.
Its 737 mm span is 6% narrower than typical for the area — the median across the 98 current wings within 10% of its size is 780 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.
