PIT to RUD Mixing (Revolution Mixing)

Use this mixing when you want to suppress the

reaction torque generated by main rotor pitch and

speed changes at pitch operation. Adjust so that the

nose does not move in the rudder direction.

An acceleration function which temporarily

increases the correction rate at throttle stick

acceleration/deceleration operation can be set. The

mixing rate at acceleration/deceleration can be set.

However, when a GY Series or other heading

hold gyro is used, since correction is performed by

● Return to Model Menu

● Touch the [PIT to RUD] button in the Model

Menu to call the setup screen shown below.

Setting method

● When using this function, touch the [INH] button

and display [ON] or [OFF].

● When you want to set the same settings to other

conditions, select the group mode (Gr.). When

you want to add settings to the selected condition

only, select the single mode (Sngl)

● A mixing curve is set.

<Normal condition mixing curve>

The mixing curve rate starts from a small

value.

For a rotor with a clockwise operation

direction (polarity), when pitch was

operated at the plus side, set so that mixing

is in the clockwise direction. First, trim at

hovering and then adjust the neutral

position.

1. Adjustment between slow and hovering
Repeatedly hover from take off and land

from hovering at a constant rate matched

to your own rhythm, and adjust the pitch so

the nose does not deflect when the throttle

is raised and lowered.

2. Throttle high side (up to climbing from

hovering and diving hovering)

*Repeat climbing and diving from hovering at a constant

rate matched to your own rhythm and adjust the pitch so

that the nose does not deflect when the throttle is raised

and lowered.

● Normally, use [Line] type.

the gyro, this mixing is not used. If this function is

used when the gyro operation mode is the AVCS

mode, the neutral position will change.

<Idle up condition mixing curve>

Set the mixing rate so that the rudder direction at

high-speed flight is straight ahead. Adjust for each

condition used.

<Acceleration function setting>

● An acceleration function can be set. This is

used when the mixture is either too rich or

too lean, which can be caused by sudden

operation of the throttle stick.

● Acceleration rate setting (Rate)
● The return time after operation (Dump) can

be set for both settings (Acceleration (High)

and (Deceleration (Low).

● An Operation Point during acceleration and

deceleration can be set independently.

When this point is exceeded, acceleration

operation is performed.
