When switching on AttitudeControl on the workbench and moving the heli by hand the servos sometimes make some jerky movements

This is absolutely normal behavior as the system doesn't simply apply full aileron, elevator or pitch input. The control input works in a much more sophisticated way. There are different curves and algorithm in the software which apply control input in a very special manner so the heli will be turned and leveled without loosing height and without moving to much around as good as possible. When turning the helicopter on the workbench this can cause some oscillations or bigger steps in servo movement (servo jumping) as the helicopter does not turn the same as it would do in reality.
