I have an idea to fly a piece of scenery but can't quite engineer the desired result in my mind. I'd appreciate any suggestions. The goal is to have a standard wall flat wall, 8'x8' that ends up at about a 30 degree angle on the US/DS axis. What I'd like to do is have the wall rotate to be parallel to the batten and flown in and out, and then when landed rotate into its correct position, then after the scene rotate and fly back out. This, by no means needs to be automated. My first thought was to mount a pipe to the top of the flat and use a swivel cheesbourough to accomplish the rotation. However, I can't come up with a simple way to lock it in the "flat" position for flying in and out. Suggestions? Is this clear at all?
