Name and Function of Each P ar t
S.BUS connection makes the wiring extremely simple.
T h e G YA440 a n d G YA441 c a n b e connected by one
3-way hub. The aileron, elevator, and rudder servos
are output from the gyro. Servos other than S.BUS ser-
vos 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 throt-
tle channel and CH11 and CH12 are spare channels.
The transmitter function settings are shown below. A
total of 9 channels are used with three axes gyro con-
trol.

rudder uses a GYA440 and
the receiver is an R6303SB.

Failure to follo w these safety precautions may result in severe injury
to yourself and other s.
Check that there is sufficient transmitter battery capacity for
flight.
• Determine the operating time of the receiver , gyro, and servo battery in the adjust-

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 GY A441 (When shared with the re-
ceiver).
• GY A441 initialization and neutral position reading. The GY A441 is initialized when
the power is turned on. In the A VCS 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 c heck 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 A VCS mode.
• In the A VCS 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 GY A441 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-

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.
