Do you mean roll and pitch get to some set angle everytime the controller is started?
I would like also to know how it's done, if it could be done to begin with.
I've seen offset for follow mode, but although the manual seem to point that it has some similar effect to that I'm searching, it really doesn't seem to have any effect at all.
I think for 8-bit, the initial angle is a combination of offset values and accelerometer/roll calibration... That's how pitch restarts at 0 degree, and roll, and yaw can achieve the desired angle. Is this correct?
