I have one of the FW 190 D9s. Now I'm trying to find a place to put it. LOL

I've got 3 Corsairs. At least their wings fold! :)

You lucky pup, you. LOL

Allowing for the 'each to their own' factor, I really do not see the point of such large models. To me the whole idea of modelmaking is to be able to appreciate aspects of 3D design - but in the case of large subjects like shops or aircraft, they are surely better fitting within a 'handle-able' cube of space.
How far back do you need to stand to get an overall impression of a 1/16 model aircraft? From across the room? I'd rather be able to hold it in my hand and check the light-lines and facets instantly, than be running back and forth trying to do the same thing.
I appreciate the detail 'from the box' is better than the 'standard' scales, but even so it's not 'that' great. I've made better detailed 1/48 models, and in the interests of domestic harmony I think I'll concentrate on better detailing of small models. I'd rather have small, well-detailed models than humungous averagely detailed ones. A collection? Maybe if you have a house as big as the average public library ;) Sorry manufacturers, but for me, size isn't everything. Detail is.

I buy them because they are great to hang from the ceiling in the garage. Let em get dusty, who cares. Strong enough to take an occasional bump and they look great with casual viewing. I got a whole airforce hanging up there.

I've got the 1/18 scale Corsair, P-40, P38, FW190D, Spitfire, and Stuka all hanging from my hobbyroom ceiling. It's like a grown-up version of childhood bedroom ceiling. It always makes me smile when I look up there. My granddaughter loves it when I lift her up so she can spin the props. Something I never let her do on my 1/48 scale planes. :)
