Hi Donsol...thanks for your reply and you
are spot on about AP not workig well at
or near maximum speed....
Fro further researching this topic on line,
I prepared the following...the "fix" is from
2012...I tried it on the Evictor and it and
the speed issue seemed to have helped a
"First: what is your altitude and airspeed? The autopilot will have a hard time maintaining the altitude if you are flying near-redline airspeed.
Open the X-Plane folder - don't start X-Plane itself.
Click on Expert tab at top middle.
Select Artificial Stability.
Click on Autopilot at top middle.
Tick the box at top left: use custom autopilot constants (to undo changes untick this box, close window and save).
Make the changes as I suggested.
Close window. Click on File. Choose Save. Start X-Plane and see if the autopilot works now.
In the autopilot settings for X-Plane, change the parameters for the pitch-controller: special/set autopilot constants/use custom autopilot constants. Change to this: pitch prediction: 2.4 seconds pitch error for full elevator: 28 pitch response time: 6 seconds pitch rate: 5 degrees/second."
The above categories have to
be interpreted slightly for XP 11...
I assume no responsibility if the above does not
work for anyone or causes any uninteended
Cheers, John H.
