Thom,

Much appreciate your detailed description of your construction. I'll probably steal some ideas for my next build.

As it turned out, the sheeting for the left and right wing panels was equal (before filling and sanding). I expect to be able to rough check the CG and lateral balance fairly soon (assuming that glassing and painting will produce only a minimal change in the ratios). At least it will give me an idea of where the battery should go.

A couple days ago, while carefully hand-fitting the servo hatches, I realized that I should have made the hatches equal, and then cut the sheeting *after* it had been sanded. You've confirmed that, and I'll do it on the next wing that I'll build for my Simla. (Parts are being cut as we speak. Thank you, Jeff!) The present wing is, in my opinion, a disaster, but I'm completing it to further my education. The replacement wing will be perfect. (Okay, how about much improved?)

Cheers,
Richard
