That [link=http://www.mh-aerotools.de/airfoils/index.htm]on line java calculator [/link] deserves a recognition. This is one of the few websites that I ever have visited which contains a serious approach to most airplane model topics: Prop design, pipe design, etc. Take a look at his home page and related links. Of course successfully making a CF pipe from scratch will also deserve more than a recognition.
Personally, I am not inclined to spend the time and money to try and research the right resins, methods, shapes etc. I get little flying time as it is.
