My 6' bomarc at 40 oz is a great glider on g25s, I thought about rolled tubes but was worried about landing damage, I originally had bt101 tubes for the ramjets but they wound up adding 4 oz rear of the cg.
I just removed them and went with profiles reinforced for landing.
Its amazing how just a bit of cardboard can weigh. I did make some rolled slip on depron tubes to go on the ramjets with chrome monokote on the bottom but they kept getting landing rash.
I'm sure it would be doable at that scale you just give up some wing loading advantage with the rounded fuse and need a soft grass field.
