slehman,

I think that the best approach for you depends on your background and how much effort you are willing to put in. One book that I think is really good is "Model Aircraft Aerodynamics", by Martin Simons. There is a web page called "Practical R/C Model Design", which is very light on theory, but gives some ranges for dimensions & proportions. The URL is www.uoguelph.ca/~antoon/hobby/pmdesign.htm. There are lots of web sites that have pretty good stuff on aerodynamics, but you may find that they are better suited for finding answers to specific questions than giving an overall understanding. You may want to do a bunch of Google searches. I have found lots of good sites that way.

Good luck,
