For anyone getting started in scratch building, your in luck. A few months ago I discovered a guy on youtube who has a bunch of videos about building scratch built foam board planes. The thing that makes him special, besides his informative videos, is his technique. I had never seen anything like it, and since I found him I haven't built a plane without using some of his ideas.
Anyone who already knows this guy probably agrees with me on this one.
Just thought I should share.
