Here is the fix…
Go to your folder for the Packages->Official->Steam->asobo-aircraft-longitude->SimObjects->Airplanes->Asobo_Longitude
(If you use Steam like I do, similar paths for Microsoft install)
open and edit the file ai.cfg with the following changes.
under…
[STICKANDRUDDER]
change the line for nav_ex1PID to the following…
" nav_ex1PID = 2.6, 0.01, 2.4, 0.45, 50.0 "
I went through and tuned the PID loop for a better response. No more swaying.
Hope this makes your flight more enjoyable.
