For anyone needing less involved display options for these, wheeled 6' restaurant racks work great and you can sometimes score them at Ollie's and Sam's Club has them complete with plastic rack pads for $79 all day long. The levels are adjustable to height.
I have three Sky Strikers, an X-19, two Conquest X-30's, a Mamba, a Stellar Stiletto, RotF Jetfire (1:72 Blackbird),a Dragonfly, a crap load of 1:72 diecasts, Masterpiece Skywarp (1:48 F-15C),a Night Raven Sp3, a 1:18 JSI Tomcat on one of those eBay stands (my landing gear held up fine but the damn rear door, the simple out-opener, broke) A BBI Hawk-with blades, a 21st Cobra with blades, a 1:48 diecast Zulu Cobra, and a vintage Tomahawk w/o blades, all on one rack.
