Phill : I recommend you find another place to save weight. It's important to build the structure according to the plans. The KRs have a good reputation for being structurally robust, so good that many builders routinely fly them overweight. You are to be commended for wanting to save weight, just don't try to save weight on structure. Willard

What is lighter, the sheathing plywood used on the fuse, or thin foam covered in BID? I've seen some guys fill the gaps between structural members and cover with glass. Anyone have experience with this technique? What's the weight diff?
