Pitch and roll centering in "Spring center" works perfectly. But a pitch offset -100 is not forward, but 6 o'clock! "Constant force" left and right seems to be the opposit direction (90 deg = left, 180 deg = right, but 0 deg = 12 o'clock and 180 = 6 o'clock). In "Grooves" the spacing has no effect. "Friction" feels a little bumpy, it means, not really constant. And "Damping" is ok.
I hope, this helps
