Autopilot vertical modes still wobbly

[flykorni]

Having tested the latest versin 1.02, with the plane spawned on the runway in ready for t/o config, I still see the AP struggling with the vertical modes. IAS hold seems to work, but as soon as I change to VS or ALT hold, the wobble starts. Also, when in VS mode and retracting the flaps, the nose pitches down and the plane starts a temporary decent. 

Please fix the AP asap, as this current state makes the Tristar unflyable for me and I guess many others, too.

Best regards, Wolfgang
