John ,
It does appear that you have been relegated to the basement for your modeling aircraft hobby
I've never taken it for granted my good fortune at having an entire upstairs living area to work and display my model Helicopters/ Fighter jets . I do wish lot's more hobbiest had the same amount of space I have .
I do like the fact some of your Helo's are hanging up in flight mode , I just feel a little sad that they have negotiate all that pipe and plumbing work . It must be a big job keeping them dust free .
Again that's a great collection of Helicopters
Kind regards John
