Books by Michael C. Niu are a good resource for this kind of info. So are Roskam's series of aircraft design books. Amazon has them all, I expect, but they're cheaper if you can find them used. Try also looking up DARCorp (Roskam's company) on the internet. They have quite a library avaialble to them, too.
