RE: electronic wind channel
I believe that you're after more of a full CFD or Computational Flow Dynamics simulator with analyzer built in. The sort of package that produces the funky color coded pressure distribution maping for a graphic body. As for where to get one I can't help you since it's well beyond anything that I'd do or pay for as a simple hobby. Some of the guys "in the industry" have posted stuff like this before so hopefuly one or more of them will chime in.
