For tank turning since the other workshop ones weren't what I was looking for
pretty basic,
switch mode switches between the on the move turning by varying the clutch, and the on the spot turning by reversing one track
Make sure you have a main clutch for you engine as this doesnt control that.
Some engine are not powerful enough for on the spot turning and start to lose rps, idk build a bigger engine or somthing
a/d input is your steering throttle or the steering from your seat (2nd one reccomended)
