Saab 340A issues

[Venom]

Downloaded the hotpatch this morning. Took her up for a flight. All was well until I reached 14,000ft. Then the plane started rocking left and right. Then a yaw movement was added and finally the nose started going up and down. The plane skidded to the left until the right wing was pointed at the sky. Manual flying helped nothing. The plane was uncontrollable.

Icing? I thought. Fought the plane through 13,000ft and I finally gave up. It doesnt even want to go down. The movement is so violent it shows the red screen. Nothing I try to do has any effects on what the plane does.

Help?

Probably the icing, we had similar issues before since XP11 icing model is a bit too aggresive with this plane, but for me i use this script which made icing more realistic : https://forums.x-plane.org/index.php?/files/file/48460-icing-simulator-the-complete-edition/

Just curious, did you use "real weather"-setting? If the rocking starts, set your weather manually to CAVOK and check again...
