They just did an article on this in Fly RC magazine (July 2009 issue). They said to start out using a roll of reflectix, and some duct tape. They state to cut the reflectix to the size of the wing x 2 and tape them together with the tape, leaving an opening to slide the wings in. You can make it a top load or an end load for the main wings. I am sure you could come up with something for the tail/empenage also. I am not sure if this is professional quality enough, but it sure is affordable.
