After not receiving any suggestions as to why my CS 727’s are bouncing and jumping all over the place I did double check to see that I  had the very latest versions of the base pack and expansion packs, and I do have version 2.7 installed.

I also systematically tried reducing the Mesh complexity down to the lower levels and the problem still exists.

I have not edited any of the aircraft.cfg either other than add additional user textures.

My simulator version is FSX Accelorator running on a Windows 7 64 bit operating system with an i7 processor.

Some help with this problem would really be appreciated.

Kind Regards
