If your plane veers off the runway in the slightest crosswind and won’t turn back even with full rudder, this fix may work for you.
It’s a formula for reducing the crosswind effect and increasing the rudder authority on any aircraft.
I’ve tested the formula on all the standard edition aircraft and can take off, fly a circuit, land and taxi them all in a 20 knot crosswind.
This fix requires a few edits of the flight_model.cfg file with Windows 10 Notepad and Calculator, that’s all:
Open your chosen aircraft’s flight_model.cfg file with Notepad and scroll down to the [AERODYNAMICS] section.
Look for the side_force group of entries, there will be four in total:
side_force_slip_angle = -2.12726
side_force_roll_rate = 0.25450
side_force_yaw_rate = 3.09566
side_force_delta_rudder = -1.79189
Copy the value for the first entry, e.g. -2.12726, and paste it into Calculator. Now divide by 4. Copy the result and paste it back into your flight_model.cfg like so:
side_force_slip_angle = -0.531815 ; -2.12726
The ; between the two values is there to retain the original value while making it inactive.
Repeat this process for the other three values.
Now look for the yaw_moment group of entries, there will be eight in total but we’re only editing two of them:
yaw_moment_yaw_damping = -16.27597
yaw_moment_delta_rudder = 0.64763
Copy and paste the yaw_damping value into Calculator and divide by 2:
yaw_moment_yaw_damping = -8.137985 ; -16.27597
Copy and paste the delta_rudder value into Calculator and multiply by 2:
yaw_moment_delta_rudder = 1.29526 ; 0.64763
Save the flight_model.cfg file and enjoy the improved ground handling!
