I built mine using the rubbermaid track system. This allows me to adjust the holders as I add to my hanger. Heres how I did it. I got the main track hung that up, then bought the shelf hanger and shelf angles. Took pipe insulations and put it on top of the shelf irons. Then set my fuselage on them. For my wings I did the same. This is all over my workbench on the wall so the planes are out of the way till I need them.
