Anyone ever hear of this guy H. L. Chevalier or his publications:Model Airplane Design and Performance, Model Airplane Propellers Selection and Performance?

DaRock, I hear ya about Stick and Rudder. I think it was meant as a "practical guide book" for seat-of-the-pants pilots back in the '40s/'50s when civil aviation was exploding after the war and far more accessible financially than today. My own flying instructor in the early '90s went on about the book to such an extent I picked up a copy. I just now found it in my aviation section with a marker at page 97 so I guess I only made it a quarter way through before tiring of it. Most of his discussion is on obvious concepts like visual perspective, relative motion, etc. It has some just plain silly topics like diving on girls houses. A classic? My '90s copy was part of the 55th printing(!) so somebody's still buying it.
