Rudder Pedals are hard to optimize because one good setting is unlikely to perform equivalently well on all types of aircrafts. In association with the setting shown below,
I normally will reduce the rudder_effectiveness by 50% of a specific aircraft, of course when necessary, so as to enhance its taxi quality while not sacrificing overall realism.
The parameter is located under the [flight_tuning] section of the aircraft.cfg file.
As shown, there are other flight control parameters one might possibly explore to realize an optimally tuned aircraft.

I know this is off topic but I could not login . Would you please send me the link to your FIP gages? Thank you

Just sent, James.
Have fun, Tom.

Tom I have no [flight_tuning] in my CFG do you mean copy everything in the post above and paste it as a whole new section in my CFG?

Hi, what aircraft are you referring to? Try opening the default C172 to see if the section is there.

Thanks Tom, for the hint, I’ll definitely try this. I’ve used numerous rudder settings in FSX as well as Prepar3d with mixed results, often leading to wiggly lines on ground.

Hope this helps. I had similar experience before using this tweak.

By using FSUIPC4 I can set up control parameters for every different aircraft.

True. What if someone who doesn’t have FSUIPC?
Also, this tweak is aimed to tune an individual aircraft someone wants to adjust in a quick and simple way.
