The SAS works in conjunction with trim. Unlike in the Huey, you have two sets of trim in the Mi-8. Im not too familiar with the autopilot, but I do know that the SAS controls the pitch, roll, and yaw of the aircraft. You have the basic trim button, and you have a trim hat that does the finer trim adjustments. The difference is that in the Huey, you have to hold your stick in order to keep a stable hover, while you can fine tune the Mi-8 so well, all you need to do is keep your feet on the anti torque pedals to keep heading. I have my hat switch for the SAS trim functions. Keep in mind that the rotary knobs on the pedestal only turn left and right, so you have to do some trial and error to get it right if you want to map it to your stick. Mine works just as it should in an aircraft - up for nose down, down for nose up, left for left wing down, right for right wing down.
