Don't forget to put some sites in that structure for some flying wires. These flat-stabs do need them, I lost a real nice GP Extra due to stab flutter, it was real nice and well built, but that one thing did it in. The one I have right now is a clone, except for c/f built into the span of rear-stab, and flying wires. I wrench that plane around too, no prob, except for a broken flying wire one time.

Also, someone did say the .40size is nearly as big as the .60...I can attest to that fact. At 15ft apart you can't tell the size diff at all. In the air I'd say it impossible, although once you see the subtle differences they are easily ID'd, but for the most part, there is no drastic difference at all. I'd have to think I'd put a YS120 in the .60 size. At least a YS.91
