Has anyone tried making a n aircraft with actual variable geometry/swing wing action? I want both wings to swing at the same angle, meshed internally, but I don't know if it's been done before. I've seen photos of a 1/72 model of a MiG-23 with that action. I'm thinking of using 1/120. The mechanism I have in mind is a pair of hard cardboard circles but placing (and designing the wings) is a problem. What do you suggest?
