If you want to make it easy on yourself, put 2 screw eyes in the ceiling and make a loop of nylon string in each one. Loop 1 over the tail and the other over the nose and you're done. That's how the hobby shop near me hangs planes that are on consignment. That, of course, is dependent on what kind of ceiling you have. A couple of anchors in a sheetrock ceiling shouldn't have any trouble holding a 10 pound plane or putting them on a stud will handle anything, but if it's a drop ceiling with panels you'll have to attach the loops to the steel structure.
