To those of you that have already flown this plane did you do anything different than what the plans call for on the wing tubes?

I’ve never done a wing tube before and my background tells me that the materials and mechanisms are ok. Assuming no flaws. I normally look for a 20G wing (+&-) and not knowing how the mechanism is put together inside the wing makes me think I should do something extra. For the tail assembly I’m leaning towards installing a dowel in the rod, I’ll probably PFM, or R6000 it in which will hold to aluminum better than epoxy. For the main wing I’m toying with making an I beam inside the tube then expanded bead foaming it in place for the main spar tube. The other option and one I know will work is to peal the bottom covering back on the wing and put a 3-4inch wide strip of glass over the center section.

Having had a GP Stuka that the wings folded on I’m leaning towards being really cautious. So I’m probably going to foam the tubes and glass the wing.

What have you guy’s seen does your wing flex if you do the nee at center section and hands at tips test is the most flex at the center section?

How has the covering held up on the wing? Is it a one or two summer cover job? Or did it hold up well this summer?
