Albert, you're a sick man.............
Migs, I've seen and made numerous kits both wheels up and wheels down that I've put on a stand. With the wheels down it gives you the opportunity to depict the plane on a final approach, with flaps down. Or it can be represented in climbout or with no wheels in cruise mode. It's a good way to display most any aircraft, wheels up or down. Most of the contract builds I've done specify a stand, so Migs, you're not alone.
The old Revell 727 kit had a really funky stand with a ball and socket arrangement that would allow the plane to be shown at any attitude, clinbing or banking. It was fantastic for 1/144 scale airliners, and I made a RTV mold of the thing and make as many as I need. They still look good, and my clients love them.
Cheers, Lee Tree
