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 flight, 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 flight-ready in an instant.
● Supporting the S.BUS/S.BUS2 connection
Only one wire connection to the receiver can operate the GYA430.

WARNING
Failure to follow these safety precautions may result in severe injury
to yourself and others.
Check that there is sufficient transmitter battery capacity
for flight.
• Determine the operating time of the receiver, gyro, and servo battery in the adjust-
ment stage and decide the number of flights with a margin to spare.
Analog servos cannot be used while in "digital servo"
mode.
• Analog servos may break down if "digital servo" mode is selected.
Do not operate the airplane and transmitter sticks for about
3-5 seconds after turning on the GYA430 (When shared
with the receiver).
• GYA430 initialization and neutral position reading. The GYA430 is initialized when
the power is turned on. In the AVCS mode, the neutral position is also read at the
same time. If initialization ends normally, the operator is informed by two repetitive
movements of the servo to the left and right.
Always check the direction of operation of the gyro.
• Attempting to fly with the operating direction reversed is extremely dangerous. Al-
ways check your gyro's direction to ensure safe flights.
Do not strike the gyro with a hard object. Do not drop it
onto a concrete surface or other hard floor.
• The sensor may become damaged during strong impacts.
Do not use trims or mixing in AVCS mode.
• In the AVCS mode all corrections are made by the gyro. Therefore, if trimming and
mixing, are turned on, operation will be the same as deviating from the neutral po-
sition.
Do not use the GYA430 for applications other than RC air-
planes.
•This gyro is designed for RC airplanes only. Do not use it for other applications.

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.

Thank you for purchasing the GYA430 airplane gyro. Compact
and lightweight, the GYA430 is designed to control the elevators
(pitch axis) or rudder (yaw axis). Features include simple set-up
and S.BUS/S.BUS2 connectivity.
Before using your new gyro, please read this manual thoroughly
and use the gyro properly and safely. After reading this manual,
store it in a safe place.
