Yes Ron, it’s a bit of an issue when you start doubling up on all your hanging models, makes for a problem when you want the other one.
Racking them up is the only way to go.
That way you still have room for the boats !!
and the cars
Unfortunately some cars & boats still have to be stored elsewhere
Admittedly I have significantly downsized both the boat fleet ( only 13 now) & the plane collection (only 17 now) but now at least it’s easy to get to whatever model you want.
