Connection

S.BUS 3-axes Connection Example

S.BUS Connection

Mounting to the Chassis

Name and Function of Each Part

S.BUS connection makes the wiring extremely simple.

The GYA430 and GYA431 can be connected by one

3-way hub. The aileron, elevator, and rudder servos

are output from the gyro. Servos other than S.BUS ser-

vos can also be used. When an R6303SB is used the CH

switching mode is set to group 7. The normal group 7

CH outputs are CH3, CH11, and CH12. CH3 is the throt-

tle channel and CH11 and CH12 are spare channels.

The transmitter function settings are shown below. A

total of 9 channels are used with three axes gyro con-

trol.

● Dedicated airplane setting

Stabilizes ight, even with hard-to-control scale models.

● Compatible with aileron or elevator control

The GYA431 can be used even with airplanes with one servo each at the left

and right wings.(S.BUS only)

● Remote gain function

The remote gain function allows the sensitivity of the gyro to be adjusted from the

transmitter and the mode switching function allows AVCS/NORMAL gyro mode

switching. Also the gain can be adjusted by the trimmer on the GYA431.

● Integrated type, compact size and light weight

High-density mounting technology makes the GYA431 compact (20.5 x 20.5 x

11 mm) and lightweight (3.5 g).

● Easy setup

Basic settings let you be ight-ready in an instant.

● Supporting the S.BUS/S.BUS2 connection

Only one wire connection to the receiver can operate the GYA431.

Before using your new gyro, please read this manual thoroughly

store it in a safe place.

Thank you for purchasing the GYA431 airplane gyro. Compact and

lightweight, the GYA431 is designed to control the ailerons (roll axis) or

elevators (pitch axis). Features include simple set-up and S.BUS/S.BUS2

connectivity.

The gyro is very sensitive to vibration. Securely mount it with the included double-sided sponge tape at a position where vibration is

minimal and the gyro is perpendicular to the axis to be controlled. Since double-sided tape will not stick to balsa, make a smooth sur-

face by cementing a smooth plastic sheet. to the frame and securely attach the gyro with double-sided tape. Provide a surplus in the

wiring and bundle the wiring with the included magic strap so that it will not interfere with the rod.

Servo Operation on the Ground

Link the servo in accordance with the kit instruction manual.

Adjust the linkage rod so that the trim amount is as small as pos-

sible.

Digital/Analog servo selection

Selection of an analog and digital servo is performed in a limit

trimmer's setting position.

A limit trimmer's motion is as follows.

Digital servo → A trimmer is adjusted by the Right rotation from

the middle point.

Analog servo → A trimmer is adjusted by the Left rotation from

the middle point.

The amount of limits -- the halfway point -- the minimum -- it will

become the maximum quantity if it is made to rotate to Max, re-

spectively. The check of operational mode is discriminable in the

display color of LED. The stability of digital-servo mode of a ight

increases in order to perform a high-speed control action.

Setup before a ight [ Remote gain use ]

Adjust the gyro sensitivity at the transmitter.

At S.BUS connection or when gyro port 2 and the gyro sensitivity CH

of the receiver are connected

Use the aileron/elevator selector switch to select aileron or

Turn on your transmitter's power. Set the gyro sensitivity to about

50% at the normal side (minus rate side) in accordance with the

transmitter instruction manual. 50% of normal sensitivity will be -70%

at the rate of the sensitivity CH so that a next graph may be seen and

understood.

Turn on the receiver power. When the gyro starts the LED ashes

performs reciprocating operation to the left and right. This places the

Adjust the transmitter and gyro while repeatedly taking o󰮏 and

landing and with the aircraft on the ground.

Transmitter adjustments must not be made while ying

because it is dangerous.

1Fly the aircraft and trim it by turning o󰮏 the gyro at 0% sensitivity

or in the NORMAL mode. After trimming, switch the gain switch

between 0% sensitivity (or NORMAL mode) and the AVCS mode three

times at an interval of within one second and then set the gain switch

to the AVCS mode position. This memorizes the AVCS mode neutral

trim position at the gyro. In the AVCS mode, do not perform trimming

during ight.

2Adjust the gyro sensitivity so that hunting (deflection of the

aircraft in small increments) does not occur in the control axis

direction. The gyro sensitivity is different depending on the area of

the aircraft rudder, air speed, and gyro used. Initially try changing

the sensitivity in 5% steps. If hunting is excessive, the aircraft may be

damaged. Hunting tends to stop when the airspeed is lowered.

The gyro has two operation modes: NORMAL mode and AVCS

mode. In the AVCS mode, angle control is performed at the same

time as NORMAL mode rate (rotating speed) control. In the AVCS

mode, the neutral keeping force is stronger than the NORMAL

mode and the flight attitude of the aircraft is forcefully main-

tained. During knife-edge flying, idiosyncrasies of the aircraft

when climbing will be compensated automatically. On the other

hand since the rudder follows when the aircraft stalls, pay spe-

cial attention to the elevator axis. To be safe, switching to the

NORMAL mode when taking o󰮏 and landing is recommended.

If the stick is moved when the airplane is on the ground, the ser-

vo will move to the limit position. In the AVCS mode, the servo

will not return to the neutral position even if the stick is set to

the neutral position, but this is normal.

If the stick is moved fully to the left or right three or more times

within one second, the servo will temporarily return to the neu-

tral position.

When the remote gain function is used normally and AVCS

mode switching is performed in accordance with the direction

of operation of the transmitter’ s remote gain channel. At the +

rate side, the AVCS mode is selected and at the – rate side, the

NORMAL mode is selected. The sensitivity is changed by adjust-

ing the end point rate. If the transmitter has a gyro sensitivity

setting mixing function, the sensitivity setting is performed di-

rectly.

When the remote gain function is not used, the clockwise di-

rection from the center of the sensitivity setting trimmer is the

AVCS mode (not used) and the counterclockwise direction is the

NORMAL mode. At the center position, the sensitivity becomes

zero. When the trimmer is turned fully to the left or right, the

sensitivity becomes 100%.

The sensitivity setting criteria by end point is shown in the

gure below. The sensitivity becomes zero between end point

-40% to +40% and becomes 100% at end point 100%.

Refer to the transmitter instruction manual and set the end

point. When AVCS is used, setting the 3-positions switch to the

sensitivity CH (there are types which cannot be set by transmit-

ter) and setting it as shown above is recommended. In the case

of a 2-positions switch, inhibiting the gyro at 0% sensitivity such

as NORMAL mode and sensitivity 0% and AVCS mode and 0%

sensitivity is safe.
