Hello,
I had exactly the same problem.
I changed the file ESDG_CitationX.ini ( in folder .../AppData/Roaming/ESDG/CitationX ).
I changed the section FADEC to this:
[FADEC]
LeftFadec=1
RightFadec=1
Throttles=0
FSUIPC=1
I believe the line I changed was the line Throttles=0
This solved the problem for me.
Greetings.
