Need a little help with my voltage sensor setup. I have it reading the total voltage of my motor battery, a 4 cell. I would also like to read the lowest cell of the battery so I can determine when to land. I set this up in Special Functions as a Play Val of the Cels using a switch. This gives me the total Voltage only. From what I've read, there should be a "CEL" selection I could use that has the value of the lowest cell. The selection I have to choose from are: Cels, Cels+ and Cels-. None of them give me the value of the lowest cell. My radio is the QX7 and is my first FrSky radio. Receiver is X8R and X6R.
