Joe,
After measuring the cargo area in my Chevy Traverse i discovered that i could potentially haul the entire plane minus the wingtips in one piece. I may amend my decision to make the wing one piece and just mount the tubes permanent in the wing tips and as you did, mount the center section and nacelles permanent . That way i only have a couple of aileron/flap servo wires to connect at the field and a couple of through bolts to secure the wingtips. Forums are a wonderful thing.
