I discovered a very strange issue with my 12x. Setting up a new pattern plane, I discovered the servo centering on the rudder servo changed slightly as I changed flight modes. I made sure I hade no mixing active and the flight mode enable had trim common between modes. I changes switch assignments and even turned off the flight modes and used only the rudder rate switch. The problem persisted in every case. I then checked another plane I had been flying all last season, and sure enough, it experienced the same issue. 

If both rates are set the same, there is no shift in center, only when there is a difference in throw and the larger the difference, then more the center shift.

If this is some programming issue, I don't know where it is?

Is there a sub-trim programmed in on the rudder?
