I did adjust my swash plate with servos centered but when leaving point G the servos are not centered anymore.
At Setup menu point G make sure you adjust your mechanical setup while electric trimming is active (Status LED is lit up in some color)! You mustn't do any adjustment while the system shows "reference position" (Status LED off at step G). This is only for finding the servos' true center positions (i.e. for attaching the servo arms to the servos) but is not used in any other way. If your servo arms are perfectly aligned in this position check electrical trimming anyway and readjust if necessary. Only the servo positions you see in trim mode (when the Status LED is lit up in some color at Setup step G) show the center positions that are used later onwards during setup and in operation as trimming will always be added to the servo output!
Please note: using AR7210BX with firmware V5.x.x the trimming is done at SETUP POINT H. Here the option "Status LED off" will not be shown anymore when you've trimmed one or more servo. To reset the trim (i.e. when replacing the servos) push and hold the button at SETUP POINT H for at least 10 seconds and release.
