Model too big for spraybooth

Revell's Focke Wulf Ta-154 in 1/48 scale is somewhat too big for the standard Badger spray booth, the one that looks like a white micowave oven with a clear window on top. As I manipulate the model inside the booth the wingtips strike the booth and a couple times I had to polish and overspray the chipped paint that occured as a result. Manipulating the model in the booth is hard enough requiring a two day process. First you airbrush the fuselage while holding onto the wings with a (gloved) hand. The next day you airbrush the wings while holding onto the fuselage. Spraying the model in one step is not practical.

I wonder how people manage to airbrush really big models like those 1/32 and 1/24 jumbo kits from Trumpeter. I'm especially interested in learning how the model is held (or secured) and manipulated during the paint application. Obviously you have to spray the really big ones outdoors because a spray booth large enough to accomodate them would cost like $3,000.
