I dunno. You might post that question in the Giant Scale Forum to see.

I am now scratch building a 1:7 C-47 with a 9.5' fuselage and 4' stab, and I will not separate for a couple of reasons. One, it will break up the scale appearance (unless done perfectly), and two, it will add weight. I'd rather live with the incremental transportation issues.

Actually, another idea comes to mind. Big planes, including my current project use carbon fiber/fiberglass/phenolic tubes to join wing pieces. This might be a start for the fuselage, although you will have the added element of tension. So, the bolts may be better overall anyway. Just rambling here- again, see what they say in GS forum.
