when the aircraft rudder moves left, and right
when the aircraft rudder moves right.

by tightening or loosening the 4-40 socket
head screw on the rudder shaft. The water
rudder should be able to deflect up if it hits an
obstruction in the water.

provided in the manual included with your
particular aircraft.
