@LyonHaart001 I found the issue.
We used to force elevator trim to neutral position when starting a free flight in MSFS 2020. This was reported as a bug by @Flysimware : FLT [Controls.0] ElevatorTrim PCT not working - [MSFS 2020] Bug Reports / Aircraft - MSFS DevSupport.
This was fixed in MSFS 2024 and we now use the ElevatorTrim FLT parameter.
This parameter is set to “016.00” in your runway.flt, which is a percentage of the whole trim range, hence the -0.68 in the [-1;1] range.
I’ll have this reviewed since it can cause regressions on 2020 packages.
In the meantime, reviewing your FLT trim values will likely solve the problem.
Let me know if it does.
Regards,
Sylvain
