Building my 7 Time Machine........
I have all my Rudder stiffeners trimmed and ready to go but they have a bow in them like a rib would and don't sit flat on the skin. I see some build sites that have no flutes and some that have flutes on both flanges. I'm paranoid that the thin rudder skin will take the shape of the bowed stiffeners. In my mind I wouldn't want to put a flute (kink) in the vertical rib (no holes) used to stiffen the skin. Maybe after dimples and rivets everything will be flat? What say the masses?
I did search on Rudder stiffeners but didn't see much on this particular subject.
