The nice thing about 1/700 is that it's small enough that you can suggest details that you'd otherwise have to model in a larger scale. In my
Essex, for example, I'm going to have planes, of course, and some side details on the outer walls, such as ducting under the island, aircraft parts, like spare wings, triced (ie, hung) on the sides. My photo references show medium gray walls and dark deck, so the aircraft will stand out against that. But I'm also going to position them closer to the openings, and the model itself is going on a molded sea base. So someone looking at the model won't be able to see too far in.
Regarding the Trumpeter aircraft and folding wings, I'll have to doublecheck (I haven't had them out in a while :
I'm not far enough along in the build ;D ). But I do think they're molded in the extended position. I'm leaving most of mine as they are, because I'm building her recovering a strike. The kit's aircraft will provide the parts. The Trumpy kits do consist of separate pieces for each aircraft, with the fuselage and wings molded in one piece, the prop as another, and the landing gear as yet more parts. Some PE aftermarket sets include props and landing gear, which can give you more of an accurate look in scale. The nicest thing about the clear aircraft--I apologize if I'm repeating myself from an earlier post--is that you can paint the chromate green (or aluminum, for yellow wings aircraft), then paint the exterior, and the clear canopy does give a little bit of depth and you can see the color.
One detail I have learned from my research materials is that the USN had developed a method of tracking which aircraft was where in the hangar deck, using a tabletop map and profile cutouts of the aircraft, with their wings folded. The cutouts may have been plywood or fiber board, and they were between 1/48 and 1/32 in scale dimensions, to give you an idea of what I'm talking about. Seeing a photo of an enlisted man, with headphones and throat mike, working with that map, gave me an idea of how to lay out the planes in the hangar.
