Ray,

many thanks, that is helpful.

Would you be able to provide me with the height of the ribs at the TE as well as the height of the root and tip ribs at the LE? Also, could you provide the length of the root and tip ribs along a rib centerline? If its easier to get more accurate readings using metric, go ahead and measure in mm.

That should allow us to loft the wing anew in CAD.

Here's the adjusted root rib with sheeting, LE, TE and aileron drawn. The aileron is 1.25" wide and 3/8" in height at the hinge line. The TE and LE are each 1/4" thick.

David.
