Coupers: Your wishes have been answered. 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.
