Jester, these wings are quite thin. The toot thickness is only 1 3/16". It becomes a case of not enough juice for the squeeze. I may at best be able to save 10 grams and then the wings would be too delicate IMO. They would handle flight loads just fine but would have to be handled with a light touch and the honeycomb pattern would be visible on the outter skin. I had one airplane a few years ago with honeycombed wings and hated it. The lower wing panel I just sheeted come out at 4.9 oz. Quite happy with that.
