Looking through some forums there are many questions being asked covering all aspects of a build from the structure to the turning mechanism. By the looks of it people prefer to have an automated system and not have stage crew turn the revolve.

I understand that for smaller sets a automated stage would work well since of the smaller weights involved but as soon as the stage is bigger and the set is on top it becomes much harder to move as the weight soon build up. Multiple motors would be needed. Its certainly not impossible but the risk of something going wrong goes up dramatically, as well as the price or course.
