Hi guys,I've been following the forum for ages but have not yet said hello or needed to post a problem. Recently i have been flying the NGX and noticed that shortly after take off and set up on LNAV the aircraft starts to sway left, then over compensates to the right and so on........the rocking gets bigger and bigger until i give up and shut down FSX. Does anyone know why this could be ? I have the latest NGX update and everything else is running well. I also have a licensed FSUIPC.Thank you in advance guys.Andrew Blake

Might be weather-related - any weather add-ons, wind smoothing, turbulence effects turned off, etc?Also, why shut down FSX? Just use heading-select or fly manually for a couple of seconds until things have calmed down again.

Thank you Christoph for your reply. I forgot to mention it does it on heading select once it has started.....BUT i do have REX active and remember something about turning some weather effects off. I'll try now. Thanks again.

S-Turns...Tick the "suppress turbulence" box in FSUIPC.Simple as that.
