Hartmut, Thanks for bringing up the discussion. I'd like to see a good analysis. If anyone out there has a metal wing and a fabric wing off the plane and can weigh it, that'd be pretty good, too.

I just wrote this out of memory and I will find out the actual weight of one square foot 0.020 aluminum and put that into calculation - also rivets. 40 pounds more than a ragwing is just way too much in my eys. I think they come even - ragwing or metal wing.
