Comes with 4 mounts, enough to hang 2 small planes.  Or possibly up to 4 planes, if they are hung from the prop or landing gear.  (up to an approx. 24~28" Wing Span) 

I have succesfully hung a 32" 3D Profile Plane (6.5oz. w/o battery) and a 18" EDF Jet (8.9oz. w/o battery), using only one mount and a piece of bent coat hanger.  (see other pictures)  Although this way of mounting the 3D plane is not very good for the wings, It is just possible.

**These are the lite Version. I removed  some excess material to make it a little cheaper**

I designed them to use #6 Drywall Screws to attach a piece of "coat hanger" or "music wire" to the wall or ceiling.  (The wire should be bent into an "L" shape from one side and a "U" from the other.  Place the short end of the "L" on the wall {pointing down} and secure with screws.  After securing both "short end L" sections, you can now place your plane's wings on the long ends of the "L's".  Now your plane is up and out of the way.)
