2. After manual takeoff i activate LNAV, VNAV and press CMD (L). The plane banks voilently and starts swinging right and left with bank-angles easily exceeding 40deg. That happens no matter what i set the bank limit selector to or which command button i choose. The only way to stop the rocking is disconnect the AP. ... Other things: The weather radar is just stuck with the test picture. A manual can not be found using the link in the manual. .... The swinging is mostly found on the FSX forum of the 757. I could not find a reference to the mentioned problems here using the search function. So hopefully somebody can help me with some suggestions?? Are you using FSUIPC and if yes which version? Thanks!

Hey everyone.

I had exactly the same problems. and no usefull answer in any forum...
i tried edit aircraft.cfg, recalibrate joystick in FSUIPC.... nothing.

Then after further 6 hours i read in an other forum about FSUIPC overwrite from the CS 757 setup.

And i looked in my folder an yes, it was downgraded to 3.9.0. but the actually version is 3.9.8. Reinstalled FSUIPC and IT WORKS !!
Autopilot and weather radar.... no problems :)

i hope this could help others with same problems...
