The pitch→rudder mixing function controls
the pitch of the tail rotor to suppress the reaction
torque (force that attempts to swing the helicopter
in the direction opposite the direction of rotation
of the main rotor) generated by the main rotor
pitch and speed. It is adjusted so that the pitch of
the tail rotor is also changed when the main rotor
pitch changes and reaction torque appears and so
that the nose does not swing to the left and right.
However, when the AVCS mode is used with a GY
Series gyro, pitch→rudder mixing is unnecessary.
●The normal (NOR) idle up 1/2 (IDL1,2), and idle up 3
(IDL3) rates can be set.
●The high side and low side rates can be adjusted.
●For a clockwise rotation rotor, the operating
direction is set so that the rudder is mixed in the
right direction when the pitch becomes plus. For
a counterclockwise rotation rotor, the setting is
opposite. The operating direction setting reverses
the rate polarity.
CW rotation: Low side (LOW) -105, high side (HIGH)
+10%
CCW rotation: Low side (LOW) +10%, high side
(HIGH) -10%

The above values are the initial values. Replace
them with the actual setting values.
Adjustment procedure
First, trim at hovering and then adjust the neutral position.

● Throttle low side (slow while hovering) adjustment
Repeatedly hover from take off and land from hovering at a constant rate matched to your own rhythm, and
adjust pitch
→
rudder mixing so that the nose does not deflect when the throttle is raised and lowered.
If the nose points to the left when landing from hovering or points to the right when taking off, when hovering
stabilizes and the stick moves to the neutral position, low side mixing rate is probably too large and when
the nose points in the opposite direction, low side rate is probably too small. However, when landing, the
direction of the nose may not stabilize depending on the state on the ground. The direction of the nose may
also become unstable when rotation of the rotor does not rise.
● Throttle high (up to climbing from hovering and diving hovering) adjustment
Repeat up to climbing from hovering and diving hovering matched to your own rhythm and adjust
pitch → rudder mixing so that the nose does not deflect to the left and right when the throttle is raised and
lowered. If the nose points to the right when climbing from hovering, the high side mixing rate is too large and
if the nose points to the right, the mixing rate is too small. Repeat climbing and diving and make adjustment
while taking the balance.

This mixing sets the mixing rate so that the rudder direction is straight forward at high speed flight.
