Uh, you might want these scanned. They're the originals...inked. Apparently, I can't remember chit! On the drawing, Bob says 590-odd sq. inches (the plans are in the truck to go scan tomorrow). It has dihederal! The LG could be done with a CF molding that would save a bunch of weight over wire. Beautiful plane!
Has Bob Emmett been asked??? He wrote that his had a G.21 .46 and that it flew quite well. Bob also wrote that he thought a .46LA would work well, but had "Saito .56??" written into the engine bay. Too heavy, I'd say. It has 1" longer inboard wing, according to another note on the plan.
So, I'm planning on getting them scanned onto a CD tomorrow, and I'll see if I can email it to you, Bob.
