<Receiver and Servo Installation>
Activate the Pitch to rudder (Pit -->RUD) mixing
function from the Model Menu, and set the curve
for each condition. (At initial setting, this function
is in the "INH" state. To use it, set it to the "ON"
state.)
<Setting example>
Activate the mixing curve of each condition with
the condition select switch.

9. Throttle hold setting
*If throttle hold is necessary, please refer to the THR HOLD
function.
10. Throttle cut setting
Throttle cut provides an easy way to stop the
engine, by ipping a switch with the throttle stick
at idle. The action is not functional at high throttle
to avoid accidental dead sticks. Switch location and
direction must be chosen, as it defaults to NULL.
*With throttle stick at idle, adjust the cut position until the
engine consistently shuts off, but throttle linkage is not
binding.
11. Swash Mix corrects aileron, elevator, and
pitch interaction
The swash mix function is used to correct the
swash plate in the aileron (Left/Right Cyclic)
and elevator (Forward/Aft Cyclic) direction
corresponding to each operation of each condition.
6. D/R function
D/R function is used to adjust the throw and
operation curve of aileron, elevator and rudder for
each condition.
*For throttle and pitch curve settings, refer to the afore-
mentioned "Throttle/Pitch curve setting"
This is normally used after End Point has dened
the maximum throw directions.
7. Gyro sensitivity and mode switching
The gyro sensitivity and mode switching
function is utilized to adjust the gyro mixing of the
model, and can be set for each condition.
● Normalcondition(hovering):Gyrosensitivity
maximum
● Idleup1/Idleup2/Throttlehold:Gyro
sensitivityminimum
● However,duringautorotationswithatail-
drivenhelicopter,thisfunctionmaynothave
anyeffectonthehighgyrosensitivity.
8. Pitch to RUD mixing setting
Note: When using a Futaba GY Gyro, or other
heading hold gyro, this Pitch to RUD mixing
should not be used. The reaction torque is
corrected by the gyro. When operating the
gyro in the AVCS mode, the mixed signal will
cause neutral deviation symptoms and the
gyro will not operate normally.
Use this function when you want to suppush the
torque generated by the changes in the pitch and
speed of the main rotor during pitch operation.
Adjust it so that the nose does not swing in the
rudder direction. However, when using a heading
hold gyro like those shown above, do not use Pitch
to rudder mixing.
