What CP and JD said. This is the method sailplane builders use and those guys are fanatics when it comes to accurate air foils. Look up ''feather cut system'' There are free plans to make it as a home built and a calculator to use to get tapered wings hands off.
Hey, you're talking about me, no offense, I am a glider fanatic.
If you go to
www.TailwindGliders.com on the "Articles/Files" page you'll find an article I wrote for RCSD on how to build an automated foam wing cutter like the Feather Cut. You'll also find an MS Excel file on how to determine the hookup points on the swing arm, it's a simple calculator if you will. And lastly, there is an instructional DVD called "A Beginner's Guide to Cutting and Bagging Foam Wings". Everything is free except for the DVD.
