Captain Sim -

If you are still reading this thread...

I modified the autopilot .xml to make it behave more like the real 727 Sperry in terms of pitch control...I also finally got the 'elevator master' switch to properly indicate its status when in other than manual mode.

I sent you a link to the updated gauge via the trouble ticket system; I'd recommend you try it out and see if it works better than the old one.
