I can get about 60 deg using a side slider on my hitec aurora with end points set at max +140/-140. I can get the camera straight ahead horizontal or straight down perpendicular to the ground depending on where I physically locate the tilt mech on the servo gear. obviously I dont get the option of the full 90 range. Important to note that if you have the tilt set to the limit you get no stabilization in the max'd out direction. I will probably bring down my Tx end points, that should prevent reaching the stops but it will reduce my tilt range.
