Sim racing pedals as rudder without additional software? L/R rudder axes: how do they work?

When MSFS first came out it only offered support for a single analogue rudder axis. So to use my sim racing pedals, which unlike proper rudder pedals have a separate axis for each pedal, I followed this super helpful guide that explains how you can use vJoy and UCR to combine two axes into one:

That all works quite nicely, but it is a little tedious to have to fire up UCR each time.

Having just built a new PC and reinstalled Windows from scratch, I noticed that MSFS now offers the ability to configure separate left and right rudder axes, which on the face of it sounded exactly like what I was originally looking for!

Unfortunately they don’t seem to work the way I was expecting them to. A moderate pressure on one pedal will result in full rudder deflection in that direction and a small push on the other pedal will result in full rudder in the opposite direction. Releasing both pedals, doesn’t re-centre the rudder.

I guess I’m a little confused as to what signals MSFS is expecting on each channel when using two rudder axes. Can anyone shed any light on this and what the expected use case is for this new functionality? I presume it would be of use for analogue shoulder triggers on a controller, but wouldn’t they act the same as racing pedals?

As I am eagerly waiting for Honeycomb Charlies, but also awaiting a racing wheel+pedals in the mail today - I am also curious as to how to set this up for as long as the Charlies aren’t available. Good to read that at least the setup in the video works, even though it requires some workarounds. Seems to me that it makes sense to use both the gas + clutch pedal as that has hardly any resistance. Hope that is possible :slight_smile:

A rudder pedal works different than a brake, clutch and gas pedalen because of the potentiometers. On the rudder the left and right are one and they use one potentiometer (10Kohm), while the left and right toebrakes, uses 2 potentiometers (10Kohm), one on left and one on the right toebrake.
So the left and the right rudder share one potentiometer 0% > 100% or -16383 to +16383, 0 is the center from there it is deflect to the right is + and left is -.

Do it is possibble to configure youre racingpedals to rudder it is not very comfortable to work with. How?
You have to calibrate the gaspedal. Then press it half way set to zero. From there you have to go to release and set axis -100 to 0.
Then press it half way set to zero. From there you have to go to press all the way up and set axis 0 to +100. The clutch and brake pedals can be configured to toebrakes.

To control this is not very well to handel. Because if release your foot from the gaspedal youre plane will yank to the left. While with rudderpedals it stayed in the center.

Hope this help to contribute to explain the difference. Feel free to experiment with this on youre racing pedals.

I have found a way to set this using vJoystick and UCR, you can set the clutch and gas pedal as a merged axis in UCR, and then set it so doing nothing with both pedals is 50% on the rudder axis. If you press the gas pedal it goes to 100% (thus right) and if you press the clutch pedal it goes to 0% (thus left). If you press both at once they cancel out and it is 50% again (same as letting go of both pedals).

The brake I set to brake axis left + right. It works perfectly, except for having no toe brake. I can now finally disable rudder takeoff assist and use the rudder to counter crosswinds.

I have only to pedals and I added another merged axis in ucr with the setting greatest and added this axis to brake left and right axis. If I press both pedals at the same time it breaks. If I only press one pedal it steers with the rudder. Crazy, but it works.

I use software for it to work

Msfs2020 should allow sim racing pedals though to save us all the trouble !

The problem is that they often have different axes. In the Logitech driver software you have the option to combine axis. Then it works out of the box in msfs

Came here to find a solution for using racing pedals as rudder pedals. I’ve got a Thrustmaster T500RS wheel+pedals.
Then I could make it work this way without any software and with Separate axis: “Rudder Axis Left” - assinged to Clutch pedal, and “Rudder Axis Right” assinged to Throttle pedal. Then go to “Sensitivity” tab in Controls for those two axises. The main settings here are: “Neutral” and “Deadzone”. They are able to limit axis at half point.
Works with Aerosoft CRJ now for example.

That works!! Thanks so much for sharing that solution, it’s been bugging me for months.

Thanks for pointing me here @TrowserOwner
I think ive now sorted mine, after removing all the vjoy stuff.
These are my settings, think they need a little tweaking still

And it was a bit of guess work on what axes to set in the sensitivity

Right now I have the MFG Crosswind ( v2 )
I’d like to buy some racing pedals but I have no more space
Can I use the racing pedals for the MSFS 2020?
Do they work okay with the flight simulator?

Yes you can, mine work fine. Read Hornette27’s post above. Study the post, you need to really understand the terms they are using and how they work in the sim. Starting with that, and some tweaking that I don’t exactly recall, my Logitech G27 racing pedals (clutch and accelerator) work as left and right rudder. But no toe brakes (so no differential braking), you’ll need to bind a switch somewhere to activate the brakes. In my particular instance, I have the Logitech pedals connected to a Thrustmaster wheel, and so the wheel needs to be nearby and plugged in to electricity and to a USB port, for the pedals to function. Annoying, but doable. Did not need any of the extra software that others mention, such as vJoy and UCR. Sounds like MSFS updated their capability so that those are no longer needed.

Can you share your settings for the G27 please? I have a G25 ever since i setup the pedals as the rudder, the plane veers to the left on take off


Here are my screens. I forget why the unusual names for the axis. The key is the sensitivity for those 2 axis’s.

I’ll give these a try. Thank you!
