Notice in this photo above I have two marks the top mark is the"zero" mark and then I removed the 3/32" balsa scrap from below my height gauge and I have a new mark that is 3/32" below when lined up with the TE centerline the wing is at the 0.5deg positive incidence. This mark I show as lower in the photo. I marked it with a dot to show myself which one to use for the 0.5 deg line
