Pans, are limited only by cable length for the tilt motor. With the current cable length you can “wind it up” and get about 3 turns (1080 degrees), but you may get dizzy.
From horizontal, the range of tilt motion is 85 degrees one way and about 75 degrees the other. We don’t say up or down because you can mount you your camera in either direction. So we can’t hit vertical or straight down.
