Hey, here's an idea, go to the AMA website, and to the archives. You can type in Bill Evans in the author search, or simitar, or whatever and you will get a list of the simitars that Model Aviation has published. You can read or print the articles, including the miniature plan in the magazine, I just print them to a file. I've only built the bugs ear, the .020 size and it flies good with an .049, but I've designed some similar planes of my own just using symmetrical airfoils, and they fly just as good, and I can make the airfoils in the 7 to 10% thickness range for speed. And hand launch so you can remove the landing gear for less drag still.
