I've worked my way through Andy Lennon's book R/C Model Airplane Design and currently reading the classic by Martin Simons, Model Aircraft Aerodynamics. My question is what's the next book for a model aerodynamics enthusiast and hopeful designer. I've heard Abbott's book, Theory of Wing Sections is pretty informative. Simons mentions a couple of interesting sounding works by H.L. Chevalier (Challenge Engineering?) in his book's appendix but I've yet to come across them. Any other good stuff out there? (I understand calculus etc. and have an ME degree..)
