Richard,
I used four 5/16 CF tubes in the wings and it only came to a total of 5.6 ozs. Did you plan on using CF tubes or rods? Since I don't have a wing without CF tubes in it I have nothing to compare my wing to. All I can say is that the completed wing is extremely stiff. Perhaps the best part about using them was the ease with which they were installed. It only took a few minutes to install each one with fast CA. The use of the tubes also allowed me to use the tubes as the alignment pins.

Bill,
I hadn't seen 5/16 CF tubes. Of course, I hadn't been looking for them.
Did you get the .312 O.D. or the .315 O.D.?
Thanks!
Richard
