Hey so I have a Q X7 transmitter and am thinking of replacing one of the gimbals with a set of firing buttons. Has anyone done this to an X7? If so, are there any particulars associated with doing this to an X7 that are different from other transmitters? Does anyone have pics of the backs of their button sets showing what they did to wire in their firing buttons? Schematics only go so far for me, but if I can see what it actually looks like, I can duplicate it.
