There is one really outstanding book, written so that the every-day person can read and understand, that focuses on flying, not RC but flying aircraft. It has a lot of information that gives insight on how airplanes work, what the fuctions of each control is and how they work, and other topics.
The name of the book is "Stick and Rudder". GBoulton, an avid pilot an RC'er, often posts here and highly recommends this book. I bought it based on his recommendation and found it to be an excellent reference source. Everything that applies to full scale applies to model aircraft. The only difference is the perspective of the pilot.. full scale the pilot is in the aircraft, where with RC, the pilot is standing on the ground looking up at his/her aircraft. Everything else applies.
Take a look at it at your local library, they just might have it, and if you like it, well, it's not expensive at Amazon.com. Get yourself a copy.
And, of course, Gettingairborn.com is another great source @
