There are some pics of the incidence mod [link=http://www.rcuniverse.com/forum/fb.asp?m=6743930]here[/link] from when I did it the first time.

First photo shows the slight elongation of the top of the rear wing bolt hole and the guide mark for the new wing position, and the second photo is of the little ply plate that will hold the wing bolt in its new position. It's easy to make the guide mark by installing the wings as usual in their stock configuration, laying a piece of 1/8" play flush with the fuse and then making the guide mark with a fine-tipped Sharpie. The change is so small that the front wing bolt hole is not affected.
