The Agusta 109SP has a very nice 4-axis autopilot which is equipped with a "Wingslevel" button in the collective.
Press "Wingslevel" and the AP takes the ship in a wings level (obviously) and 6 degrees nose up attitude.
Without the SAS (stabilization) which is always active as AP has to be ON in Flight, the 109SP gets very nervous and shaky to fly.
