Way down my "to do" list is an F5U. Can't help but admire the genius of the design (hey, it actually WORKS!!)
I am going to paint mine like an "Aunt Jemimah" pancake on the cover of a pancake-mix box, with melted butter and syrup oozing down it. I may end up taking a pic of such and creating a decal or something so it looks "real". I guess it would have to be considered "desert" camo, what with the light brown/dark brown "pancake" look!
But, I would have to watch out for "seadude"s teeth-gnashing interceptors unsatisfied with merely a "PBJ" (see What-if Board for details)!!
