S.BUS Connection

Mounting to the Chassis

Name and Function of Each Part

S.BUS connectivity minimizes wiring. The GYA430

and GYA431 can be connected by one 3-way hub. The

aileron, elevator, and rudder servos are output from

the gyro. Standards servos 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 throttle channel and CH11/CH12 are

spare channels.

The transmitter function settings are shown below. A

total of 9 channels are used with 3-axes gyro control.

● Dedicated airplane setting

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

● Compatible with elevator or rudder control

The GYA430 can choose and use an elevators or a rudder.

● 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 GYA430.

● Integrated type, compact size and light weight

High-density mounting technology makes the GYA430 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 GYA430.

S.BUS Receiver

This is a three axes

connection example. The

aileron uses a GYA431 and

the receiver is an R6303SB.

＜ GYA430 elevator mounting ＞

The turning direction which xes the

gyro can be any direction up to 360°

relative to the pitch axis.

Mode

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.
