We are doing a production in which the director desires a very simple thing to fly -- a very tiny sign (about 18" square). It can hide behind a border, and fly down a short distance just to be visible for something of (apparently) great importance in a scene. Unfortunately, of course, we have no fly system. Normally we have a very old-school method of using an array of small pulleys and rope to achieve such a thing. A young person asked me, and I don't know the answer: has technology progressed to the point that there is a simple device (perhaps a tiny remote-control winch of some kind) that can do this relatively cheaply and of course safely? The sign could even be made of foam, so a rather minimal weight rating would be ok. Thanks!
