I'm learning as I go, so please bear with me.

The Uproar 60 has an aluminum wing tube that slides into a paper tube that will be glued in the ribs. The instructions do not mention the kind of glue that should be used. I have wood glue, epoxy, and CA (thin, medium, thick).

Since you have to slide it in, that rules out CA. I would opt for 30 minute epoxy, myself. Not sure the wood glue would stick to the aluminum very well.

I think I asked the question wrong. The aluminum tube gets permanently mounted in the fuselage with about 10 inches sticking out on each side. The paper tube gets glued to the ribs inside the wing. The wing panel slides onto the aluminum tube. The purpose of the paper tube seems to be to guide the wing ribs onto the aluminum tube.

I would use thin CA. Should not only glue it in. But harden it some as well. Would give it that little extra wear resistance and peace of mind.

First, the aluminum tube does not get mounted permanently in the fuse. By being able to remove it from the fuse, the plane is easier to transport.

Second, wood glue is fine to mount the cardboard tubes into the wing and the fuse.

I realized last night that the aluminum tube 'floats' in the fuselage. The plywood caps glued on the outer R3 ribs keep it centered when the wings are on. I originally thought I was supposed to epoxy the aluminum tube into the center section.

Thanks for the info. I've gotten good answers and insights every time I've asked a question here.
