1 = Proportional power steer
Proportional power steer applies rudder in proportion to
joystick movement – the further the joystick is held over,
the greater the applied rudder.
2 = Bang-bang power steer
Bang-bang power steer applies continuous rudder in the
direction of the lever movement – to improve control, the
speed of rudder movement changes with the angle of the
lever. For maximum speed, push the lever hardover. If you
return the lever to the center position, the rudder will
remain in its current position.
