I'm wondering why there isn't the option to map the tilt or pan onto something else on the controller, there's only the 3 x GPI options in the TX config which seems useless unless there's something out there which can be plugged in (I can't find anything except wheels - be great if there was a simple little thumb wheel unit or something). I'd love to assign tilt function to the small rocker dial on the left side of the controller (or the focus or iris dial) and leave the joystick dedicated to panning only. Anyone know of anything or perhaps I'm missing something? Anyone else like to have the option of mapping tilt or pan away from the joystick?
