Another way to ‘fix’ this issue might be the pax load.
If there’s only a pilot in the left seat, placing another one in the right seat might fix this problem as well, although that’s not realistic, but due to the exaggerated MSFS moment arm simulation.
@EnoughBard39362 I don’t remember using rudder trim in the real one either, but since the yaw axis simulation of the JF Arrow is at least questionable, this might be a contributing factor as well.
(Missing) engine cant could also be a reason (if there’s any on the real one)
