Great sleuthing there DirtyPool...
First let me say that I didn't put a caliper to the tube so I can't be 100% on the exact size... but I laid the round over a rule and it's definitely bigger than .5" and less than .635"...
It's right at .5625 or 9/16"... it's POSSIBLE is could be as big as .588 and that last tube you mentioned would work... Calipers please....
I asked Max abot it and he said that the plans specified a 1/2" tube, but that the manufacturer may have substituted for what they could source easily. Then I mentioned how advantageous it would be if was 1/2" so CF stab tubes could save an oz in the tail and 4-5 in the nose...
he said he'd check to see what the shpeil is...

I found some 9/16 inch CF tubes, but they are the I/D measurement, not O/D.
TUR-09 Carbon Tubes / Roll Wrapped .5625"(9/16")ID x .033"WT x 29.5" $24.00
They do have this one though:
TUR-08 Carbon Tubes / Roll Wrapped .555 ID x .033" WT x 28.5" $25.00 So, what would the O/D be if the ID was .555" plus .033 wall thickness?
Found them from ACP Composites.
