Having problems calibrating an airfile

Having problems calibrating an airfile with a new Gmax model in FS2004.

The aircraft.cfg has been set up with the correct contact points, fuel tank locations, root chord etc. However, after modifying the aircraft.cfg file so that the airfile and visual model work together -the aircraft now oscillates in yaw when in AP HDG HOLD, or at high speed.
Might this have something to do with Wing_Apex, or Wing_Sweep, which have been altered to gain a correct CG?

I'd be very grateful for any response.

Thanks in advance

It is my understanding that the visual GMAX model has nothing to due with the flight dynamics while in flight. Your problem has to be in the *.air file or the aircraft.cfg file.

Just my thoughts...am I wrong?
