I might be making a mistake! What I decided to do when building the wings to make the wing profile come out like it says on the plan. Does this make sense?

Also included time lapse recording of building out the lower wing. Starts at 5:45

There are lots of interesting videos in my Sopwith Camel playlist:

Not just my videos, I've also included some great videos of restored Sopwith Camels in the air, an interview with Sir Thomas Sopwith, and some of the other videos that have inspired me during the build.
