The above photo shows how I store my models using slat board and slat board hooks with a short length of PVC conduit. This works good for models under 10 lb. and 48 inches in wing span.
For the bigger airplanes I modified some retractable garage storage systems (http://www.sears.com/shopzeus-racor-ceiling-storage-lift-heavy-lift-overhead/p-SPM5140622501?prdNo=32&blockNo=32&blockType=G32) and mounted them to the rafters. I use a drill with a length of rod that has a hook on the end to raise and lower the airplane. This works really well because I can use this as a lift while working on the electronics or airframe. Makes it easy to get underneath and fix gear issues etc.. I hope this is helpful info. See you at the field.
