I have a few wing racks as described above and a couple ladder racks from home depot that are screwed to the wall.
The wing racks are simple to make from 3/4" dowel, 3/4 pipe insulation and some 1x2 pine or poplar. I prefer poplar because it drills nicely and is more durable.
About the only special tool your need is a 3/4" spade or forstner bit.. I prefer forstners for the clean flat bottom holes they make.
Everything else can be done with hobby tools. I cut my last 2 sets with a Zona razor saw and miter box. I was to lazy to haul out the table saw

I'll take some pictures tonight

The ladder racks work great for fuselage storage. The are about $5 at Home Depot
