Without a discussion group like this, we'd probably have muddled along with approximations forever.

I just went out in the hanger and weighed a fabric wing (covered with ceconite and doped with colors to match the paint job on the metal wing) followed by a metal wing. This was done on my digital bathroom scale, after calibrating itself (caused by moving it from one location to the other). The wings are virtually the same except for the covering. Results? Fabric wing 50.0 lbs Metal covered wing 65.6 lbs Assuming the same is true for the opposite side, the total difference would be 31.2 pounds. Now, to address Greg's' comment. The roll rate would be faster with the lighter wings, due to the smaller amount of inertia to be overcome. When the same amount of aileron deflection/rate is applied to the fabric covered wings, and the metal covered wings. It has been over 33 years since I went through Navy Test Pilot school, so I have long ago forgotten the formulas to calculate the difference in the response. I am not sure that most pilots would be able to notice the difference, but trust me, there would be a difference.
