The top comes off on positioning pins and will have handles built under it, just like the bottom. The bottom just fits through the doors. Yeah, almost forgot about that early on, but tested it out. Plus it is upstairs... I'm more worried about the weight to carry it down... lol
Yes, it's built in 1/144.
Well, if you mean the McQuarrie Concept X-Wing, then yes... never was good with the technical ship names, lol . The litte one and the big one just getting started were from Rich/REL at Sovereign Replicas. You see them pop up from time to time. Both are very nice kits.
