My plans (1990 version) show plywood sheeting on both sides of the lower wing butt ribs and the innermost ribs on the upper wing. I've seen photos of wings with only the inboard side sheeted. I already built one of them sheeting on both sides and it's really heavy. So, I'm wondering if it's ok to sheet just the inboard sides. Any thoughts?
Also I'm wondering what kind of changes have been made in the plans and if it would be worth it to buy a new set.
