No, the scope of RCAdvisor.com is any calculation that involves flying models. I needed the airfoil calculations for the propeller editor. I decided to expose its functionality since it is useful in its own right.
If you know (or can take a good guess at) the airfoil of a given model airplane, by studying the behavior of the airfoil in the virtual wind tunnel you can learn a lot about the flying behavior of the overall model.
