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.

First, trim at hovering and then adjust the neutral position.

  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.
