ptulmer,
Funny you should mention that, I've got a 60 size original design profile on the boards right now! I agree, the 60 sized motor seems to be an orphan engine these days. I think the 3D numbers game has done that, needing the right power to weight ratio with a light enough wing loading. My ship will have, I can't remember exactly but its in my design book, around 880 sq in of wing area. Span is going to be 42". I like to keep the span short and the chord large to keep the center of lift close to the fuselage. That helps keep wing rock out of harriers. My numbers aren't far off from what is found in many "40" sized machines. What I will do is play around with moments to get the right CG without needint weight in the tail. That's one of the nice things about scratch building. Best of luck with your project. Don't cave. Stay with it and build your own!
