Before the First Flight (continued)
Moving the 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 26.
The right-hand stick controls both elevator (pitch fore/aft) and aileron (roll). Pushing the stick forward will pitch the
nose of the helicopter downward, allowing the helicopter to be flown forward. Pulling the stick backward will pitch
the tail of the helicopter downward, allowing the helicopter to be flown backward.
The elevator trim can be used to help keep the helicopter from drifting forward or backward when in hover with
no elevator stick input. For example, if the helicopter drifts forward when in hover, add back elevator trim until the
helicopter hovers as level as possible with no forward drifting.
