I always liked to suspend my model planes from clear threads hanging from the ceiling.
Technology has moved forward a lot since I was a boy modelmaker, though.
Today’s invention is a quadrocopter which can support a model aircraft (say 1/72nd scale) via a few fishing lines.
This can be programmed to skim the ceiling in a preset flight pattern, bringing to life such models in a way that no static stand or display case can…especially if the model has a motor-driven propeller.
A more advanced version would involve two such ‘copters whose aircraft would chase each other overhead.
