I took some pics of the top center section and the tube does go through the third rib and hits the stop ring on the aft side of the rib.. It sure was a pain in the butt to get the bottom wings on, very tight.. I actually had to put the left wing on and slide theCF tube in, I will work on this to make it an easier task. The tube slides in the panel fine, so it's an alignment problem.. I also have to tweak the top wing holes at the center section a little, not a big issue..


I do see what you mean about the 12 screws that attach the top wing and the cabanes, this was a task in the comforts of my shop, I can only imagine what itis like at the field in 90 degree heat!! Mine are a cheap philip's head with the built in washer with a 5.5mill lock nut on the back, this is being changed for sure.. I think I will make a ply piece on the the nut side and have the nuts locked into the ply and then change to a good allen cap screw...
