I am only familiar with the Zen as a 3 axis gimbal. I am sure it can be done with others it is just a question of channels, switches, sliders and dials on your TX/RX kit. My Futabas have 14 channels available, 2 sticks, 2 sliders and 2 dials, and lots of switches 2 and 3 positions. You can program them many different ways.
I actually use 2 TX/RX for a total of 28 channels, I don't use all of them, but more than 14. I can switch camera to photo mode or video mode, point straight down at the flick of a switch or switch to straight ahead mode or FPV (tilt up and down but only 45 degrees laterally with auto return when you let go of the stick) mode on the camera, trigger the shutter, switch between cameras for downlink. And a few other features as well like auto pan or POI mode automatically circle an object on the ground and keep the camera pointed at it.
And it all works well...
