<Model Basic Setting Procedure>

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.

A curve setting example is shown below.
●Pitch to RUD mixing curve (Normal)

Use the hovering system and set this curve to

match take off and landing and vertical climb at a

constant speed.

●Pitch to RUD mixing (Idle up 1)

Use this curve in 540º stall turn, loop, and rolling stall

turn, and adjust it so the fuselage is facing straight

ahead when heading into the wind.

●Pitch to RUD mixing (Hold)

This function is set so that the fuselage is facing

straight ahead at straight line auto rotation. The

pitch of the tail rotor becomes nearly 0º.

9. Throttle hold setting

*If throttle hold is necessary, please refer to the THR HOLD

function, p.127.

10. Throttle cut setting

Throttle cut provides an easy way to stop the

engine, by flipping a switch with the throttle stick

at idle. The action is not functional at high throttle

to avoid accidental dead sticks. The switch’s

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 defined

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 GY601, GY502, GY520,

GY401, 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 suppress

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.

Activate the Pitch to rudder (Pit -->RUD) mixing

function from the Model Menu, and set the curve
