If you're talking about the airfoil that just folds the LE over, I think there's some magic about where it ends.

I'd think a KFm-6 or maybe a KFm-4 would do goof for a 1/2A wing. I've been building planes with foam AND KFm airfoils for about 8 years. Remove the paper from the inside, shipping tape over the paper on the outside like the RC guys, fold the 2 halves over a foam board spar, add power and fly. Trying something like a combat kitten but I blow up to the 30 inch wingspan. The wing profile is based on a simplified KFm airfoil design (KFm-2). Once the ruler was clamped, I held the bottom of the airfoil with my left had while I used my right hand to fold the top half over the edge of the ruler. The plane has a large accessory compartment to hold your GoPro camera, board camera, LiPO batteries up to 4000mAh, and other FPV gear.. Made from CNC cut foamboard material with printed graphics, the Observer FPV is extremely durable. Next, I needed to mark the place where the top of the airfoil would meet the bottom of the airfoil. 1.

First I laid the 30" strip along the edge of the white paper, right where I made the fold in the previous step. Download the Airplane Pattern Now! Next, I laid one of the 20" strips right on top of the 30" strip and lined it up with the inside edge of the wing (the 6" side). It has an enormous collection of over 23,000 model plans available for download.
