    Hi everyone.
    I'm building my frame to have a 4DOF (pitch, roll, heve, yaw).
    So I'm adding the 5th engine (D-Box style).
    Until today I have used the 3DOF system and I managed to get the Pitch, the Roll, the Heave.
    Now how do I get the "YAW" effect on the 5th motor?

    Yaw is set as any axis would be in Axis Assignments, but with a dedicated actuator it would be 100% allocation.

    Or do you perhaps mean traction loss, which has a pivot point near the feet?

    I mean the effect of the car when it skids the rear (rotation of the rear of the car).
    I know the effect is called YAW.
    Right?
    I have to set this effect to make the 5th engine work.
    How can I do?

    Normally where a rig is constructed to simulate the rear end breaking loose traction loss is used, where it pivots near the feet: https://www.xsimulator.net/community/faq/traction-loss-in-simtools.175/

    Yes, with pin near the feet.
    So when the car loses rear grip on the track, the rear chassis rotates to the right or left.

    What is the difference between "traction loss" and "yaw"?

    Yaw pivot a round a center point, such as a helicopter, traction loss pivots near the feet, like a drift cars, they are very different axis and effects.

    Ok perfect explanation.
    I need to setup the "loss of traction" effect.
    So how do I activate the effect?
