User manual

Futaba GYA441 is a compact and lightweight integrated rate gyro designed for airplanes. It supports S.BUS/S.BUS2 connection, making wiring extremely simple. The GYA441 has three ports: Port 1 for S.BUS input/aileron and elevator input, Port 2 for 2nd aileron or 2nd elevator/gyro sensitivity input, and Port 3 for aileron/elevator servo output. It is compatible with both digital and analog servos and features a remote gain function that allows you to adjust the gyro gain from your transmitter. The GYA441 also has a built-in LED monitor for easy setup and operation status monitoring.

Here are some of the key features and capabilities of the Futaba GYA441:

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-
PHQWVWDJHDQGGHFLGHWKHQXPEHURIÀLJKWVZLWKDPDUJLQWRVSDUH
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 GYA441 (When shared with the re-
ceiver).
• GYA441 initialization and neutral position reading. The GYA441 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 (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 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 GYA441 for applications other than RC airplanes.
•This gyro is designed for RC airplanes only. Do not use it for other applications.
Do not place gyro near heating equipment (engine, motor, ESC,
battery, servo, etc.).
• Always allow the gyro to adjust to the surrounding environmental temperature be-

tional 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.
