[WWI] 1/144 scale WWI aircraft

[Jim Landon]

<<While trying to imagine how something may sag up ...>>
 
We need to stop using the word "sag". The curvature of the fabric has nothing to do with sagging from gravity. The fabric is drawn into a curved shape by the shrinking of the fabric caused by the dope. Turn the plane upside down and the fabric on the underside of the wing holds the same shape.
 
Build a balsa and tissue scale model airplane and you'll see.
