I'm trying to decide on launch rod size for my 43" wingspan RCRG, and 3/8" seems about right. The only difficulty is I can't find 3/8" paper tube anywhere.
The way my glider works, the launch lug is mostly internal, so I need about 34" of 3/8" tube. I like the looks of ACME conformal lugs, but they are just too short for what I need.
I appreciate any pointers to vendors who might carry 3/8" tube.
