I purchased a Ronin SC Combo recently (i think it's the same as Ronin S), in used condition. But, he had a centering problem. He almost always panned to the right. After many resets and calibrations, I suspected the JOYSTICK sensors. Such sensors are composed of two potentiometers. THE SOLUTION was simple: put contact liquid, type W40, on the two sensors. Heads up!! No need to unsolder the sensors! I put the liquid superficially, while moving the joystick lever. Now it works like a charm!!  

I hope this excellent tip will be useful for this entire forum community and that it will also be useful for DJI engineers, in the way they build their equipment.
