I have been experiencing this issue where the throttle axis arent in sync.
Lets say I have a flight, takeoff and everything is just perfect and when I disengage the autopilot for landing, throttle for engine 2 stays stationary and my input only works on engine 1. (Always throttle for engine 2)

I might add that my quadrant just works fine, this aircraft is the only one that does this, and this is not true on every flight, but 1 in 4 flights.
This is rather annoying and needs to get fixed.
