I totally agree with Hogflyer and NCIS. I have a lot of my planes like this also. The way I usually hang them is to use an eye hook and bungee cord to hang it with. I will screw the eye hook into the wall (preferably in a wall stud so it doesn't pull out), then open up the eye hook enough to put the bungee cord in it, close the eye hook loop, and then hook the landing gear of the plane with the hooks on the bungee cord. This keeps the fuselage flat against the wall and since the landing gear is what's hooked you don't need to worry about any "hanger rash".

Hope this helps
