Throttle jitter on Turnigy 9X


Junior Member
Hi guys!
I've encountered a problem, and it's getting really annoying.
I have a Turnigy 9X V2 transmitter with stock modules, and er9x firmware. After several months of use the throttle stick signal started to jitter, and jump up and down. It's quite random when and where it does this, but it's frequent enough that I can't fly with it.
It seems like a broken pot, but I've replaced it multiple times, and tried to repair the original, but it's still the same.
I also desoldered the wires from the frontal pot, and switched the signal wires (maybe it had a problem with the analog input port). It worked, but only for a week.
Now It's doing it again, and I ran out of ideas. Any Suggestions?
In this graph I sampled the receiver for 3 seconds. The stick was all the way down.
