Just recently, on the 757 when I take off and make a banking (within limits), the aircraft turns using the the ailerons but then the a/c employs the rudder thus causing it to turn and yaw at the same time - excessively. All this happens while the a/c is on autopilot.

The yaw dampers are engaged.

There is a null zone via FSUIPC

The aircraft operates normally otherwise.

AIIR#5 (video pls)
AIIR#6

Any camera add-ons?
