I don't think the plans call for 7076 anywhere. Most places it's 6061-T6 or equivalent aluminum. > I need to make the hinges for the control surfaces and was at Swellendam yesterday and while looking at a Rans S7 I saw all the hinges are made of about .9mm stainless plate bent into "U" shapes. I asked if this worked and the Rans has 1700 hours on with not a single snag. Can I go this route also? It depends on the stainless. For example, 304 is not much better than 6061-T6, but there are other stainless steels that are much better.
