Bug HLG

John - I added one rib to each side for the Lil' Bugger and used the stock dihedral angle. To double check I just measured to the first rib in from the tip instead. It flies great and I was still able to get in at 3.5 ounces. For LB2 I'm going even wider (possibly 44") and using a thinner, narrower chord AG 30 seiries airfoil. I hope to have it finished to fly this weekend.
