I don't actually know if this is a bug or not, but I've been told I should be able to tap directly on the selected input between the selector arrows and open a window to enter a custom input such as Pitch + Roll. This isn't the case. The other guys in the main Discord whom I was asking for help in setting just that input and where to do so said they could do so easily right there in the properties menu, but it doesn't work for me. Is this a mobile/PC difference maybe? If so I'd like to know how to achieve the goal of a single rotator to gimbal my jets. Two rotators stacked does t hold up to the weight, you see. I'm on version 1.1.109.
