In case you were wondering, as I was. The same rib jig will work for all Eagles, per my Email from Leonard today. This came up for me when I was offered a LE-XL rib jig, but started to think maybe I really wanted to build a Double Eagle or Cabin Eagle (folding wings!). The two place airplanes have wider forward spars, so the aft rib gets shorter, but same airfoil profile, overall chord, thickness.
