S.BUS Connection

Mounting to the Chassis

Name and Function of Each Part

S.BUS connectivity minimizes wiring. The GYA440

and GYA441 can be connected by one 3-way hub. The

aileron, elevator, and rudder servos are output from

the gyro. Standards servos 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 throttle channel and CH11/CH12 are

spare channels.

The transmitter function settings are shown below. A

total of 9 channels are used with 3-axes gyro control.

Do not strike the gyro with a hard object. Do not drop it onto a con-

crete 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

Do not use the GYA440 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.).

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.
