Convert Logitech G29 Pedals into Rudder Pedals

Are you a flight simmer and a simracer? Are you contemplating to buy rudders or a whole set of wheels and pedals? Do you have a spare wheel lying around? With this tutorial you can Convert Logitech G29 Pedals into Rudder Pedals!

Disclaimer

This tutorial uses a 3rd party software (Joystick Gremlin), so any errors caused by the software is not in my jurisdiction. However, it’s been stable so far.

Pros :

New rudder pedal
Build quality is quite OK (compared to 3d printing)
Can definitely handle your foot

Cons:

Differential braking requires another step
Both pedals braking requires lifting your foot off one pedal
The G29 stays connected (you can use an adapter to USB for this though)

Step 1 : Download Joystick Gremlin

and of course, install it.

Step 2 : Merge Axis

2.1. Press on Tools -> Merge Axis. The window below will appear.

2.2. Press New Axis

2.3. For G29, the Y axis is the Gas Pedal, and the Slider is the Clutch Pedal. Then merge axis into a vJoy device, and select the axis too. When finished, close the window.

Step 3 : Assign Brake Axis

3.1. Assign the Brake Pedal (Z Rotation) to any axis to your choosing.

The result after assigning the Brake Pedal. Note that merged axis is not shown here, only in the merge axis window.

3.2. Press the button with the gamepad icon at the top left to start delivering input to vJoy, or proceed to step 4 for Differential Braking

Step 4 : Assigning Differential Braking (Optional)

We will be reusing the Gas / Clutch pedal for Differential braking, but they will be actuated together with rudders (merged axis). You may do 4.2. (Gas Pedal) first, but here we’ll walk through the Clutch pedal first.

Here we will limit the left/right brakes actuation in sim when another button is pressed. I’m using the button 24 (mode) of my Saitek X52, as it is a toggle. Or you can set it to a momentary button, so that it acts like the NWS HI function of an F-18.

4.1. Assign the Clutch (Slider) pedal to X Rotation of VJoy 2. Then, add a condition for it to turn on only when the button is pressed.

4.2. With 4.1. finished, Assign the Clutch (Y Axis) pedal to Y Rotation of VJoy 2. Then, add a condition for it to turn on only when the button is pressed. You may assign the VJoy axis as you want.

4.3. Press the button with the gamepad icon at the top left to start delivering input to vJoy

Step 5 : Simulator Config

5.1. Make sure that the setup matches your Gremlin setup. Rudder for the merged axis (step 2), wheel brake for the brake pedal, and wheel brake Left / Right as setup in step 4.
