Status: offline 		Thanks Dave. I was starting to wonder if I had to go back and look again..

Let's see if I have this right.. 66% of a 9.875" chord = 6.5175" and 66% of a 9.75" chord = 6.435" so there is a difference of .0825" in the placement of the thickest part of the airfoil.. That doesn't seem like enough to mess up the incidence +1 degree does it?

When I built my Twins plane using Randy's wing and a HurriKane fuse I had to raise the LE a little over a degree, and then when I swapped back to one of Danny's wings, I had to do the opposite.

Status: offline 		Lee, the difference in the high point is only part of what's causing the incidence change. The LE of the wing is still basically in the same place, but the TE is raised due to the shape of the airfoil. You wouldn't have an issue if it were a flat bottom wing. Take the Lyle wing you made the saddle with, and just sit it .125" farther back on the saddle (so the TE is in the same place as the R200 wing), and see how far off the incidence is. It probably farther off than the R200 wing.
