What better way to store bulky RC planes than to make them look like they're flying near the ceiling?  I've found that these brackets can support roughly 15 lbs together which covers most RC planes of this size.  Inside dimension of the bracket holds a 187 mm or 7.4" max wing.  Use the larger holes to insert a drill extension for easier installation.  If you're using these in a garage, outdoors, or want a more rigid set up, use PETG, ASA, or a fiber infused filament.
