Sabfoil Red Devil 636 Red Devil 636: a legacy wing, no longer in Sabfoil's current range. 550 cm², 640 mm span, aspect ratio 7.50. The current wings that match it within ±5% area and ±8% aspect ratio, from Sabfoil's own published specifications.
Projected and flat area run 3–8% apart. A marked area is one whose brand does not state which it publishes, so a match inside the area tolerance may be comparing unlike figures.
