Get Compufoil. This program will take the root, tip airfoils selected and produce all the airfoils in between. You specify spacing etc. At the size of our little airplanes, any symmetric airfoil will do just fine. Just stick with the chord and thickness of the original. In my design work I typically use NACA 00xx airfoils with about 12 to 13 Percent at the Root and 10% thick at the tip. Then, I set the max thickness to about 35% of the chord. All this can be done in Compufoil. [link=http://www.compufoil.com]Compufoil Web Site[/link]

I've looked at Compufoil and while it looks like a nice program I have to question just how much I would use it. I don't plan on scratch building that much but then at $40 it might be worth the investment to save on future frustration???? I'm on a pretty tight budget at the moment and any money I have needs to go towards building supplies. Thanks for the tip though.
