I appreciate everyone''s input here. I made an Amazon purchase last night. I bought Wing Sections by Abbott and Theory of Flight by von Mises. I considered Elements of Airfoil and Airscrew Theory by Glauert thinking it might have a bit more discussion on prop theory but ultimately reasoned von Mises had it covered and was cheaper.

I don''t want anyone to think all I do is sit around and read books. I currently am flying a Bridi Kaos and working on a "scratch built from plans" Duelist Twin in the Kit Building forum where I am making good progress and have had some thoughtful input along the way:[link]http://www.rcuniverse.com/forum/m_7165436/tm.htm[/link]. I have begun working with Profili 2 and XFOIL. My ultimate goal is to be able to design my own aerobatic and scale r/c planes.

Balsa, foam and many composite materials are very inexpensive in commodity form and make for rapid prototypes. I''m having a ball tinkering in this hobby.

EDIT: Regarding Abbott, see my comments on post 23. I don''t recommend it as a reference for model designers.
