Anyway want copy parameters model other super ship out wont have too great negative impact GNP US will certainty have fun doing Just think will design Airfoit month Since have used NACA 64A208 section Vixen will section choice 64A208 really thinned 64A210 section thinned lower its profile drag allow model have better penetration against wind downside thinning section low-speed maneuverability suffered somewhat maximum coefficient lift C1 diminished somewhat Nonetheless thinner section does have wider speed range thick section wasnt needed strength wing since model didnt have long wingspan 64A208 also pretty good choice inverted flight however rather old section andas suchisnt very much used other hand since can carry good load ballast quite forgiving may overlooked airfoil As airfoil should attempt build section accurately possible wants perform its intended design applications 64A208 Ive used wings skinned plywood sanded accurately possible Probably good vacuum-bagging job would
