So i recently got Accu-Feel and i had it running with a few light planes and the PMDG 1900D and it worked perfectly. So then i moved up to the Pmdg 737 ngx and when i first went to take off the plane started to more or less (Woful) side to side. I had trouble keeping it on the center line and even when i landed, the plane did the same thing again and it was really hard to keep it even on the runway.When i turned accu-feel of it didn't do it so i'm positive it's to do with Accu-feel. Has anyone else had this problem? and is it maybe to do with the Accu-Feel settings?

I had this (or similar) problem, but only with first builds of Accu-Feel, after few updates everything started to work as it should.
