Small Scale Military Headquarters

Hey guys. A while ago I purchased one of the BBI Hellcats that came delivered minus the under-the-fuselage/wing-root segment. I purchased it with the intention of building one of my own and since I was just gonna glue the wings onto it (doesn't need to do the hinge/bend stuff) I figured I could go-it alone. Problem is I just don't wanna do it. If there is an already-made solution then I figure I'll look there first.

Any help and/or suggestions are appreciated.

John
