My storage is mostly 3/4 PVC pipe covered with foam insulation. The type of hanger depends on the wing style or fuselage size. Planes with fixed wings get a simple inverted "Y" hanger. Those with detachable wings that will fit in the eves are hung on spaced racks & the wings on wall racks. Bigger planes are mounted individually along the wall. Large biplanes with wing wire are hung from the ceiling by hooks & wide velcro straps. Probably have less then $30 invested in the whole thing.
