As for the wing tube I measured it with digital caliper. It looks like it is pure metric size as OD is exactly 22.00mm and length is 650 mm. I just sent an e-mail to pbgcomposites with question what can I do about it.
So far no luck with the wing tube. Whoever I turn to responds "We'rs sory, wo don't carry such odd size". Someone told me to use thinner tube and wrap it in masking tape to fit 22mm hole. I don't like it at all.[

I checked all parts again and I can say it is beautyfull plane

Very nice design and well built. All parts fit very well.
I finished both wings. This is the easiest ARF I ever worked with. Goes together like a Lego. Of course if you use supplied hardware. I gave myself a littel more work as I used different horns and pushrods.
The rcommended throw on ailerons is 12.5degree that is abut 3/4 inch My setup is 1-1/4 inch on low rates and 2 inches on high rates (about 35 degree). HS-5645 works great here.
Wings are mounted to the fuse by four plastic screws. All holes fit with 1/10 mm tollerances.
The tail goes as easy as it could be. The stab and the fin went into slots the the fuse without slop at all. Again very nice fit and all square out of the box. To keep joints strong but flexible (I expect gas motor will be shaky) I used Elmer glue. It dries much longer than 20 minutes epoxy but I can wait
