WARNING
Failure to follow these safety precautions may result in severe injury to
yourself and others.
Check that there is sufficient battery capacity.
Do not operate the model and transmitter steering wheel
for about 3-5 seconds after turning on the GYD470 (When
shared with the receiver).
• GYD470 initialization and neutral position reading. The GYD470 is initialized when the
power is turned on. 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 (a little).
Always check the direction of operation of the gyro.
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.
• 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 position.
Do not use the GYD470 for applications other than RC cars.
•This gyro is designed for RC cars only. Do not use it for other applications.
Analog servos cannot be used.
•The use of analog servos may cause servo trouble.
Do not place gyro near heating equipment (engine, motor,
ESC, battery, servo, etc.).
• Always allow the gyro to adjust to the surrounding environmental temperature before
flight. A large temperature change during use will cause drift and other operational
issues.

sion.
• The contents of this manual are subject to change without prior notice.
• Futaba is not liable for any potential damage (accidental or otherwise) that
may occur after installation.
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.
● Dedicated RC Drift car setting
Vehicle straight-line and cornering performance can be increased without
taking into account the effect of the road surface, etc.
● Remote gain function and mode switching function
You can adjust gain from the transmitter (3 or more CH) by using the
remote gain function. Gain can also be adjusted with the trimmer on the
GYD470. The mode switching function allows AVCS/NORMAL gyro mode
switching.

Thank you for purchasing the
GYD470 RC cars gyro. Compact
and lightweight, the GYD470 is
designed to control steering for RC
Drift cars. If the transmitter has 3
or more channels (capable of 3CH
adjustment) the gyro sensitivity can
be adjusted from the transmitter.
Features include simple set-up and
S.BUS/S.BUS2 connectivity.

that it will not interfere with the rod.
Link the servo in accordance with the kit instruction man-
ual. Adjust the linkage rod so that the trim amount is as
small as possible.
When using S.BUS servo, initialize a parameter.
Make the servo operating range as wide as possible.
Make the numerical value of EPA (ATV) equally in left and
right.

It is possible when using the S.BUS setting compatible
transmitter to change the servo to "SR Mode" and improve
the servo response. If the servo can't be changed to SR
mode, do not set the TX to SR mode.
