I have been studying several designs lately wanting to build my own plane. The flaps on planes can be flat, tapered to a point at the trailing edge, constant cord, tapered, elliptical.... Does it matter as far as flight characteristics are concerned how the flaps are built, other than rigid, or shaped. If I have a flap that is 3" at the root and 1" at the tip or a flap that is 2" at the root and 2" at the tip they have the same area. Will they fly the same? Do we shape the flaps purely for aesthetics? I really would like to know.
Thanks,
