see how that helps.
Don't do the flap hinge fairings. They are very bad. They increase the
frontal area many times (pressure drag), increase the side area (skin
drag) and worst of all, they have an opening at the rear which is the
worst aerodynamic thing you can imagine. The hinges are fine as is,
leave them alone, except for the outer one (the double one), but this
one can be modified (or you could create a better fairing for it). To
give you an idea for a better "outer flap hinge fairing" look at the
attached pictures. I made a mold but never installed these fairings as I
decided later to modify the flap hinge itself.
