Features of GYD470 Features of GYD470
● 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.
● Integrated, compact, and light weight
Compact size（20.7x20.7x11mm）and light weight（3.7g）realized by
high density mounting technology.
● Easy setup
The GYD470 can be used immediately with minimum setup.
● Supporting the S.BUS/S.BUS2 connection
Only one wire connection to the receiver can operate the GYD470.
● Only for Futaba digital servo

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.

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
issues.
When using an S-FHSS receiver, a transmitter that can switch
between "Digital servo mode" and "Analog servo mode" must
be used in analog servo mode. The servo that connects to the
gyro uses a digital servo.
• It may not work in S-FHSS receiver + Digital servo mode.

Use the included double-sided sponge tape to firmly at-
tach the gyro perpendicular to the control axis, at a posi-
tion where there is as little vibration as possible. Make the
Gyro mounting position
The direction of rotation fixed by the gyro can be any
direction within 360° relative to the steering axis controlled
by the gyro.
Steering servo Steering servo
Link the servo in accordance with the kit instruction
manual. Adjust the linkage rod so that the trim amount is
as small as possible. Adjust the linkage so that the left and
right movement angles are equal. EPA (ATV) should be
100%. When using S.BUS servo, initialize a parameter.
Make the servo operating range as wide as possible.

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.
