Just to revisit this -- the mystery of why the CWS and autopilot works so well on Mark's system and not for me is spelled a-c-c-e-l-e-r-a-t-i-o-n. On a plain FSX SP2 system the CWS is broken and the autopilot will not hold a VOR/GPS track until the ALT HOLD switch is engaged in the alt hold mode. On Acceleration, they all work as they are supposed to. Just wanted to clear up this mystery that has been puzzling me. Dutch

Hi Dutch, thanks so much for figuring that out! i had exactly the same problems with pitch control as you did. I saw your post so I decided to try it.  I uninstalled SP2 installed Acceleration, and now the autopilot works exactly as it is supposed to.

This is my first post here, so I just want to add that I really love this bird, it is a joy to hand fly, but it's even better now that I have CWS working well.
