Default 12x rudder centering issue



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 Ichanged flight modes. Imade sure Ihade 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 rudderrate switch. The problem persistedin everycase. I then checkedanother plane I had been flying alllast 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?

At this point, I would open a new model and do a reset, then start programming manually in what I wanted. I had the elevators miss-porgrammed once and the trim only affected one side. After some head scratching, ... A reset and restart from scratch helped me stumble on the fix.

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

Itried everything, the problem persists. I contacted Tony Stillman at Radio South, who tells me this is a calibration issue. It has probab;y been present all along, as Iwould never have noticed it in flight, only switching to different rates for snaps and spins.
