This isn't exactly what he had in mind but it is as close as dammit is to swearing... and it does (almost) fit in this orientation on a 20x30 foamboard sheet.

That's awesome. Thanks for making it. One thing to note is that root cord on upper half should be a little longer than 12", 12 and 1/8 to be exact. In most cases that won't affect the overall construction of the wing, but in case someone wants it to be a perfect fit, they need to compensate the length of curved surface.
When I get back from work today, I will post another version of my template, that requires simple measurements instead of protractors. It will give builders another option, since I aligned it differently.
By the way if you'd like I can attach your template to the first post and give you credit for it.
Also I am happy to report that this wing survived ~ 20 flights at this point, and 20 landings on different surfaces, some of which were far from smooth.
Also I crashed it twice because I don't like to sit home on windy days. Once during launch against concrete runway and once in a dive on a football field.
The first time servo popped off - new piece of double sided tape fixed the problem. Second time motor+gift card ripped out.
Both times I was able to get back to flying within 5 minutes.
by my Calculations Average speed is ~ 65mph
I'm planing on buying a high speed, high torque motor and downsizing the propeller and making a second wing just for those windy days at AMA field. 500-600 watt setup should bring me closer to 100-120mph.
