I guess I'm the only one who did'nt trust that method. I threaded and epoxied a 1/4 by 20 stud into the wing root rib and used a plastic wing nut to hold the wings SNUG againest the fuselage.. I totally abandoned the bolt thru the wing tube. And also for the tail sections, I epoxied the tubes into place in the fuselage and into the stabs....I figured I would never take the stabs off anyway, plus they had some play with just the bolt thru the tube....Andrew
