Family Fusion X-Series Chord 140 mm Brand’s category All-round / freeride Disciplines wing, kite, prone carbon (prepreg, PMI core) · 2025
No current wing from another brand is within the tolerances; the nearest are drawn instead, ranked closest first. The Axis Spitfire 670 (#1) is already over it. Select a numbered wing to draw it — up to three at a time.
The Fusion X-Series MkII runs 5 sizes, 700–2,100 cm²; aspect ratio moves 5.8–6.2 across the range.
Its 640 mm span is 21% narrower than typical for the area — the median across the 114 current wings within 10% of its size is 812 mm.
No current wing from another brand is within ±5% of area and ±8% of aspect ratio of this one.
None of these is within the tolerances above — each misses on area, on aspect ratio, or on both, by up to 1.4× the tolerance.
