There is an open Issue about this where you can track progress, but it’s not currently something we’re working on.
Are your joystick axes still configured like in this image? And is that how they were configured by default, or did you set them that way?
In the image the Z axis is set as -1 to 1 values, when it should be 0 to 1000. You also don’t have the R axis configured (it should be -1000 to 1000), without which you won’t have yaw (turning) control over your vehicle.
If that doesn’t resolve your issues then it makes more sense to continue the discussion in this thread.
