longitudinal instability at speed under AP

asked Apr 30 by aupif (18 points)
On all my Xplane 11 aircraft, when in flight and APengaged, I experience sudden activations, up and down, of the trim or the elevator resulting in strong pitch oscillations around the set altitude. I use Saitek X52 yoke and throttle.

Any advice will be appreciated.

Thanks in advance.
