Here is an article for a simple holder for painting Airliner fuselages if you like to attach the wings after they are painted. The required materials are some 60 thousanths sheet styrene, a large and a small paper clip. I cut a strip of styrene wide enough to fit through the fuselage where the wing locating tabs
go and then cut two small strips from that same strip and glue them top and
bottom of the strip to act as a stopper, on the end opposite the stopper I drill
a hole. The strip goes through the fuselage and the small paper clip goes on
the other side of it to hold the model in place. The large Paper Clip is bent
to provide a hook on both ends with one end to go through the strip, this is
to hang the model when the paint dries. Of course you could just look at the
pictures and it's pretty straightforward....it works for me! Good Luck!
