Are you tempted to do a gear-up diorama?
That's a very interesting question. Short answer is yes.
I've amassed a pretty decent collection of unbuilt RCAF/RCN aircraft in 72 and 144. The intent has always been to have them on display, and I find aircraft generally look better gear up & canopy down. To that end, I've acquired dozens of feet of clear plexiglass rod. I think a nut epoxied on the inside of the fuselage, and if I run a die with matching threads on the rod, I can have a simple and secure mount. Bases could be simple wooden squares or circles with a nameplate.
Gear up is sometimes more difficult than gear down though!
Part of me is tempted to paint the canopy interior black and forgo cockpit detailing completely - these are models for "me" and not for contests or articles. Apart from decals, almost entirely OOTB. Almost like wooden desktop models.
I'd like to pair a 707 gassing up some CF116, an Airbus with some CF18, and the CC330 with some CF35 although I'm not sure if 144 F35's exist. I also have a CC141 I'd like to do the same with a CB-52
In fact, there's a host of 72nd kits I have that I'm considering replacing with 144th; pretty much all the 4 prop jobs, and a few of the 2 props (Albatross, Dash 8, Twotter, Caribou)
