Thanks to both Lou and Hat Trick! I have seen very little RC combat and never seen any SSC., so all I can do right now is guess that inside loops and inside banked turns are the maneuvers that are most common, therefore you need a lifting airfoil like the E203, but is it neccesary to have the under cambered portion of the E203 if I'm going to build a flying wing instead of an aileron/ elevator ship? The undercambered part of the airfoil would probably be hard to monokote.
