I am looking at adding the reinforcing tubes to the trailing edge of the wings in my S7 SS. Aircraft Spruce has the 3/8 tubing in 2024T3 and 5052-0 aluminum. The 2024T3 is 4 times the cost but stronger. What have others used for this? I have heard of builders using carbon fiber arrow shafts but I have also heard that carbon fiber has a strong corrosive affect on aluminum. Thoughts?
Thanks,
Greg
