Our own Cafeenman has a site with some good material on it.
ORIGINAL: CafeenMan
This is an article I've been working on over the past several months. It is simply my approach to model aircraft design. Others may do things differently and end up with as good or better results.
The one thing I keep seeing in this forum and in my e-mail is people asking how big a plane to build for any given engine. Personally I think that is the wrong question to be asking.
The "right" question is given an engine, how do you design an airplane that performs like you want it to? My answer is to choose an overall weight and a wing loading which allows you to figure out a wing area. From there you select other parameters for the wing such as airfoil, aspect ratio, etc.
Anyway, I don't want to rewrite the entire article, but I would like to get feedback from those who read it.
