Okay, so 12, maybe 13¢ per hub with S&H. I had tried rolled tissue hubs, but never without gluing it to a 1/16 balsa backup which anchored the tang of the propshaft. When you bang an A-6 into a wall, the tube needs the support of the strip of balsa behind it or it will fold at the center. A thinwall Poly tube is lighter than a tissue tube of equivalent toughness, and requires no backup.
 

 Rolf Svensson bought some thinwall .070 for A-6 wingposts. We'll have to weigh a couple against the 1/16 square tissue tubes I use.
