I was flying with AP on at the time - CH yoke and pedals, registered FSUIPC. I was adjusting pitch at the time so perhaps that is the issue - will try it again when I get a chance - unfortunately SP2 for the A300 has just been released so I'll be flying that for the next few days :)

The 707-300 does NOT use FSUIPC. So FSUIPC cannot be the cause of any problems with the 707-300.

From Support KB#5937:
Q: I have problems with using FSUIPC and your 707 Captain.

A: 707 Captain does not use FSUIPC so we do not support any issues with FSUIPC.

I'll probably be taking the A300 up for a few flights because of the SP2 update as well. :o
