Unifoil Vyper 190 Vyper 190: a legacy wing, no longer in Unifoil's current range. 1,226 cm², 865 mm span, aspect ratio 6.10. The current wings that match it within ±5% area and ±8% aspect ratio, from Unifoil'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.
