Hi steamroller. Thanks for the extra pics. One more question, is the underside of the wing concave or convex. Difficult to see from the pics. Only asking as I am in the process of making my own GL style ply wing ;D

Convex and concave from pics I've seen.  Look at the H 105 wing profile. or the NACA 63-412 or NACA 64a210(130% increase in thickness).  While I can not be sure since I have not held any of these wings, this is only my best guess.  I am currently using the H 105 hydroplane profile designed by Tom Speers specifically for lower speed sailing dingies. We will see.  Maybe a couple weeks before it is finished.

Looking forward to getting an update ;)
