I think you need to consider if the fuselage has a soft bottom or not. If it will not deform (C'ARF, or maybe molded balsa sandwich stuff), then you can hang, or put the fuselages on a rack of sorts. If the fuse is soft like the bottom of my Passport (2009 model, fiberglass, flat on bottom with ridge), then you want to keep it on the landing gear. So you need a wider shelf or hang it by the prop I guess.

When I hang pattern planes from the ceiling, I fasion a yoke to hang them from the wing tube. The rope around the tale stabilizes it and supports almost no weight.
