None of these variables are really good for what you want. P Factor is something different then torque forces. And the other two have more to do with general inertia, meaning with fast force changes.
The torque on roll comes from mainly two variables -
“torque_on_roll” - what a surprise^^,
and with the modern prop model enabled also
“prop_mod_moment_scalar_roll” from the engines.cfg
Setting the latter to 0 - should disable any torque on roll you experience.
But the left banking shouldn´t be that high in the TBM850. Do you have the latest Version of the TBM? Or do you have only a slight roll to the left and it just bothers you (which is ok, btw.) Just want to be sure, you are not having bugs.
Kind Regards
