I did buy these carbon fibre tube suggested. Diameter too large! Maybe 0.1mm! Maybe the squared tube in wing are smaller on earlier versions of the plane?
11.5mm would have fit.

I doubt the manufacturer made any changes there. Maybe the crash put a slight kink in your square tubes.

For only 0.1mm interference, you might try expanding the square tube with your aluminum pipe or a similar size piece of tubing, by making it slightly out of round on the end, adding some lubricant, and running it inside the square tube, while carefully rotating the pipe. The square pipe is very thin and easy to bend, so it shouldn't be hard to enlarge.

I measured my aluminum pipe to be 11.5mm, while the carbon tube I bought measures 12.0mm. The square wing tube opening measure about 11.8-12.0mm I.D. near the corners. Hope that helps.
