Moving the left-hand stick to the left will turn (yaw) the nose of the helicopter to the left about the axis of the main
shaft. This is accomplished by increasing the speed of the lower main rotor blade while decreasing the speed of the
upper main rotor blade.
Moving the stick to the right will turn (yaw) the nose of the helicopter to the to the right about the axis of the main
shaft. This is accomplished by increasing the speed of the upper main rotor blade while decreasing the speed of
the lower main rotor blade.
The rudder trim can be used to help keep the nose of the helicopter from rotating to the left or right when in hover
with no rudder stick input. For example, if the nose of the helicopter drifts to the right when in hover, add left rudder
trim until the nose stays as close to straight as possible. Also note that further adjustments to the rudder trim can
be made using the Main Motor Proportional Mix Trimmer Pot as outlined on page 32–33.
