The fuel-tank is giving me a lot of headaches. It’s situated in the center-section of the top wing. The trailing edge of the top wing has a notch in it for easier access for the pilot. I have no idea how the wing profiles looked like between the fuel-tank and the trailing edge.

I have a photo showing the internal structure of the wing, but it’s really not too clear. However, it suggests a concave shape, as shown on my drawing. However, it goes against everything I have ever seen before. In any case, I am not happy with this part. I will have to revisit it again later.

The center section will be 100% sheeted.
