Was that 11 pound differential for the pair of wings or 11 pounds per wing? We’ve had a group member who had wings in his shop and put each on the scale. He found a 20 pound difference between the fabric covered and the metal covered. This matches the old-time handed-down wisdom. Hence, I always quote it as the possible weight difference. Others have said they got less of a weight difference. That’s great. How? Thinner aluminum?

According to my logs, metal wings empty weight increased by 11 pounds--seems about right to me. 2. You can take the metal off, or at least open it up, every 20-30 years--I just did it. 2-part self-etching epoxy primed everything. This will last a long time! Plus we now have all those inspection holes. 3. You should not leave airplanes uncovered outside, especially a 'Coupe--they leak. Ceconite recommends recover every 7-10 years for outside planes. The fabric wings will be safe from hail but the rest of the plane will be hail-damaged? 4. Piere is looking for that polished aluminum look--I say go for it! Just another view--John N2138H
