RE: Designed a Balsa DLG
Many DLG's use a small vertical peg at the tip used to lauch so that you can wrap your fingers around the peg and avoid the punctured covering look.
Bandit, you're obviously going to need to either put the peg through the spar or tie it in to the spar somehow so the spar can take all the tensile pull during the launch. A small tube of 3/16 diameter carbon should work fine. I would not want to trust wood in this case.
