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 GYC441 (When
shared with the receiver).
• The GYC441 is activated when the power is turned on. The neutral position is also
read at the same time. If initialization is successful, you will see the servo move left
and right slightly.
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 driving from the neutral position.
Do not use the GYC441 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 damage.
Do not place gyro near heating equipment (engine, motor,
ESC, battery, servo, etc.).
• Always allow the gyro to adjust to the outside temeprature before driving. A large tem-
perature change during use will cause drift and other operational issues.

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
Boosts vehicle straightness and cornering ability, regardless of surface type.
● 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
GYC441. The mode switching function allows AVCS/NORMAL gyro mode
switching.
● Integrated, compact, and lightweight
High density mounting technology makes the GYC441 compact (20.5 x
20.5 x 11 mm) and lightweight (3.7 g).
● Easy setup
The GYC441 can be used immediately with minimal setup.
● S.BUS/S.BUS2 support
Only one wire-receiver connection is needed to operate the GYC441 with
S.BUS/S.BUS2.
● Only for Futaba digital servos

Thank you for purchasing the
GYC441 RC car gyro. Compact
and lightweight, the GYC441 is
designed to control steering in your
RC car. If the transmitter has 3 or
more channels (capable of 3CH
adjustment), gyro sensitivity can
be adjusted from the transmitter.
Features include simple set-up and S.BUS/S.BUS2
connectivity.

When using SR mode, connect as shown on the left.
* When using SR mode, SBUS connection is not possible.
wiring loose and bundle it with the included nylon strap so
that it will not interfere with the rod.
Link the servo according to the kit instruction manual. Ad-
just 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.
Equalize EPA (ATV) left and right.
It is possible when using the T7PX 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.
