a easy adjustable rack for planes is to go to home depot or other hardware store get some adjustable shelf standards the kind with the slots in them they come in 4'-6'-8' lengths get the # of shelf brackets you need screw then to the wall and use foam plumbing pipe insulation for padding they are allot like NCIS's wing rack but you then can adjust for wing and fuse sizes as they change a 4' tall unit will hold as many as 4 planes jammed in but I have 3 in mine fitting loose and out of the way without any trouble installs with a screw gun/screw driver in a pinch and some scissors to cut the padding
