T-Rudder with 2 Virtual Brake Axes (no brake button)

[coreyo]

This is a bit of a new spin on an old question. I currently have a gladiator mk II, and I've hooked my T-rudder pedals directly into the gladiator, removing the little blackbox altogether. I was able to get the A2B set up to achieve on/off braking on each wheel via the pedal axis. I would like more fine tuned control, however. My current goals are as follows:

1. create 2 virtual axes: left brake and right brake.
2. When I press the right pedal on my T-rudder, the right brake axis should increase. When I press the left pedal on my T-rudder, the left brake axis should increase. Both should remain at 0 when the T-rudder axis is centered.
3. My joystick does not have a brake trigger, and I do not want to have to press a button for the axes to register. Having the rudders and brakes activate at the same time is what I want.
4. I don't want to have to use any extra software layer to make the axes work.

I have attempted to follow other people's profiles. I set 2 unused axes to 'Combine: BrakeV3' (one with + and one with -), bind the #Axis to 7 on both (my current T-Rudder axis), but so far, when I test the axes, I see no movement when I use the brakes. Any help is appreciated.

Whoops, I accidentally posted this message on the wrong thread. Re-posting it here:

I did manage to figure it out today. Apparently you don't need to use the Combine parameters at all. Here are the basic steps:

1. Identify the physical axis that you want to use as the input. In this case it's My T-Rudder pedals on AxID 7 (Rot Y)
2. Find two axes that are unused. In this case it's AxID 6 (Rot Z) and AxID 8 (Slider)
3. Set the AxID of the two unused axes to the same AxID as the physical input axis (in this case, AxID 7)
4. Make sure that the physical axis has the "Cn" (Axis With Center) box checked. It should NOT be checked for either of the virtual axes.
5. Check the "R" (Physical Data Inversion) checkbox on only one of the virtual axes

That's it. In the bottom "Physical Axes" section, I set the 'Input' value to "Virtual" for both of the virtual axes. I'm not sure if this is necessary at all.

Voila, that's all that's required. One of the virtual axes will be triggered when the physical axis moves to the left. The other will be triggered when the physical axis moves to the right. For me, this is ideal. I can bind the rudders and left/right wheel brakes to the same pedals axis without having to worry holding a button down. For the purposes of maneuvering on the ground, this suits me just fine.

Here's how my setup looks:

And here are 2 images showing that each of the virtual axes are bound to the left and right pedals respectively

2. When I press the right pedal on my T-rudder, the right brake axis should increase. When I press the left pedal on my T-rudder, the left brake axis should increase. Both should remain at 0 when the T-rudder axis is centered.
3. My joystick does not have a brake trigger, and I do not want to have to press a button for the axes to register. Having the rudders and brakes activate at the same time is what I want.

This configuration will result funny if one use in DCS Warbirds (P-51, Bf 109, Fw 190...), because in take-off run is need use rudder, and applying side brake at same time will have nasty effects.

@Sokol1 , I have considered that. It's not really a problem at all for the C-101. In the case that it does become a problem in other planes, I can bind the axis + modifier/switch in DCS World itself for the toe brakes. In that case, it will ignore the toe brakes when the modifier button is not held.

Before the release of T-Link I have tried "axis2button" and "axis2axes" options, but testing in DCS Bf 109 and Fw 190 I give up of the idea fast.

To set up separate brakes on the left and right pedals from VKB-Sim T-Rudder MkIV will result funny because in take-off run, we need to use rudder, and applying side brake at same time will have nasty effects.
Is this correct?

I set up my T Rudder for differential braking.
Works beautifully

How do you do that?

I'll post some screen shots in the morning.

You can set the brakes to come on at a set percentage of axis travel. So only uses rudder/nws for first 20% of axis, after 20% the brakes come into effect.

I am new to this and don't know the procedures step by step. I have the VKB-Sim T-Rudder MkIV plugged directly to the VKB Gladiator Pro MKII base without Blackbox. I don't want to use the blackbox too many wires (lol).

This is how I set up differential braking for my game in Aces High 3.
I used Axis 1 & 2 as a copy of Axis 7 (Default Axis).

Open VKB Config
Click VKB Sim T-Rudder in your top window
Select Your Profile Tab and use two axis' that are not in use (in my case 7 is the main axis, so I used 1 & 2)

1. Tick Enable Axis (EN)
2. Tick Visible in HID(Vs)
3. I set Precision same as Original Axis (in this case Axis 7)
4. Set Combine to Average.
5. Set Sign to Axis 1 Positive & Axis 2 Negative.
6. (IMPORTANT) Set #Axis to 7 (Your default Axis Number that you are copying)
7. Set Percentage to whatever you want (this is the point of axis movement where braking starts to take effect), in my case 10% of axis travel, am going to increase is though.
8. Press SET to load to your pedals.
9. Go to Test Tab (see images below)

Once set up, go to your game and bind the new axis' to your Left & Right Brakes.

Original Default Setting

T Rudder Default Setting

Modified Setting

T Rudder with Diff Braking Setup

Your Test Tab will like like this on start

T Rudder Default Test Tab

And should look like this after modification

T Rudder Modified Test Tab

Pressing Left Rudder (Axis RotX) Increases Axis X

Pressing Right Rudder (Axis RotX) Increases Axis Y

Additionally, I set a button on my stick as a park brake.

Hope this helps
Dont forget to save a back up file just in case

I found discrepancies between Pressing Left Rudder and Pressing Right Rudder pictures.
Did you notice that? Is that the way to go?

[NikonGuy]

What discrepancies did you find?

The X and Y axis used for the brakes does not use centering whereas the ROTX Axis (Rudder Axis) does use centering at 32,767
When you press the left rudder to 0, the X Axis (Left Brake) will go from 0 to 65,565 (no centering on this axis).
Equally the right rudder moving from 32,767 to 65,565 will move the Y Axis (Right Brake) from 0 to 65,565).

This setup works perfectly for me in my gaming
I use an axis on the stick for both brakes together and also works as a park brake.
