From a storage perspective, I’d say it’s dependent on your shop and space. I have a larger shop, but after assembly including hardware, I took it all apart. The components were hung high on the walls out of harms way, but suitable for show-and-tell. On a practical basis, when the fuselage gets married to the empennage, tail fins would be in the way, and if you use a rotisserie (as I did), you need the rear surface where the vertical stab mounts for mounting. It was over 2 years before the VS & HS got reassembled again as part of final assembly.
