Ensuring correct alignment
CAUTION: Take care to ensure correct rudder sensor alignment. If the sensor
is not correctly aligned, the autopilot system will not perform accurately.

Vertical alignment

When viewed from the front (as shown in the illustration below), the connecting rod should
be as level as possible, so the ball-joints at each end are level. It should also remain parallel to
the tiller arm's plane of rotation at all times.
If misalignment exceeds +/-5 the ball-joints will bind or fail.
