I am familiar with symmetrical, semi symmetrical and flat bottom wing airfoils. Has anyone tried a wing with the top and bottom of the wing parallel (like a plank), possibly about one inch thick.
I am thinking of a wing about 48" long and maybe a 9" chord. If anyone has tried this type of wing, I would be pleased to know how well it works. I know that some flying wings have an airfoil of this type and they seem to work well. Any responses would be much appreciated.
