Slingshot PFH 657 657: a legacy wing, no longer in Slingshot's current range. 743 cm², 657 mm span, aspect ratio 5.81. The current wings that match it within ±5% area and ±8% aspect ratio, from Slingshot'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.
