After reading this manual, store it in asafe place.
INTRODUCTION

The GYA460 is a flight attitudecontroller and stabilizer designed
exclusively for model aircraft. Inaddition to control by 3 axis gyro
VHQVRUÀLJKWDWWLWXGHLVFRQWUROOHGE\D
3 axis G-sensor.
The beginners mode assists newpilots with automatically controlled
flight attitude angle and horizontal
level return. Gyro mode and gyro offmode can also be selected.
2FEATURES● Low profile, small size and lightweight.
● Easy setup● S.BUS compatible. Only one connection is necessary between theS.BUS receiver and GYA460.
● Three ﬂight modes can be selectedby transmitter switch.
● Sensitivity adjustment can set aileron, elevator, and rudder separately by GYA460 trimmer.
● Parameters can be set by GYA460
SET button and LED.
● Tailless wing compatible.
*Attitude cannot be controlled in the stalledstate in which the rudder is ineﬀective.
*Gyro CH(1CH,2CH,4CH,5CH,6CH)F/S (failsafe setting) can't be used.
*Always use only genuine Futaba transmitters, receivers, servos and other optional
accessories.

PRECAUTIONSWARNING
Failure to follow these safety
precautions may result in severe
injury to yourself and others.
Check that there is suﬃcienttransmitter battery capacity forﬂight.
■ Determine the operating time of thereceiver, gyro, and servo battery in
the adjustment stage and decide thenumber of ﬂights with a margin to spare.

Always check the direction ofoperation of the gyro.
■ Attempting to ﬂy with the operating
direction reversed is extremely
dangerous. Always check your gyro's
direction to ensure safe ﬂights.

Do not strike the gyro with ahard object. Do not drop it onto
a concrete surface or other hardﬂoor.
6■ The sensor may become damaged
during strong impacts.

Do not use the GYA460 for
applications other than RC
electric airplanes.
■ This gyro is designed for RC electric
airplanes only. Do not use it for otherapplications.

The GYA460 assists flightby beginners. However, thisdoes not mean that RC model
aircraft can be flown alone by acompletely inexperienced flyer.
Inexperienced flyers should fly
safely under the guidance of aninstructor.
The GYA460 stabilizes the flight
attitude, but this does not meanthat any model aircraft can beflown. Use it with a model thatwas made properly and can fly
reliably.

MOUNTING to the AIRPLANE
Firmly stick the gyro to the chassis with thedouble sided tape supplied. Install the gyro
at a level place near the center of gravity
where there is little vibration. It can also be
installed at the side or rear of the chassis.
In this case, change
the chassis gyro
mounting direction
setting.
Mount thegyro facing
forward in thefuselage.
*Depending on the airframe material such as balsa, etc., the adhesivestrength of the double sided tape may
drop. In this case, prepare the mounting surface well.
*Do not use a product other than the double sided tape supplied. Vibration may result, causing
the plane to become uncontrollable.
13SETTING
1.Transmitter Setting
If using 2 aileron servos, WING TYPE
should be "2AIL".
If using 1 aileron servo, WING TYPE
should be "1AIL".

*Flaperon and air brake aileron
mixing can't be used.
*The reverse direction of AIL1 andAIL2 has to be the same.
In a case where the transmitter does
not have 2AIL in WINGTYPE:
Use in the state of 1AIL.
The respective servos are connected
to AIL1, AIL2 of GYA460.
GYA460 will make 2 aileron servosmove.

2.Transmitter Switch Setting
Assign transmitter CH5 to a 3-position
switch, and set the function to “GEAR” .
This setting enables use of the Beginner
MODE, GYRO-OFF MODE, and GYROMODE by switching a switch. When you
want to change the direction of operation of the switch, perform reverse setting at the transmitter.

Beginner-MODE＜Blue＞

・This mode is suitable for level flighttraining of beginners.
・Control is implemented by gyro sensor and acceleration sensor.
・The fuselage flight attitude angle islimited to approximately ± 80° .
・When the transmitter sticks (exceptthe throttle) are set to neutral, automatic horizontal level control returns
the airplane to the level state.
・The limit angle is linked with transmitter dual rate. For instance, if dual rate
is set to 50%, the limit is then restricted to 50%. So maximum angle would
be 40 degrees.
GYRO-OFF＜Yellow＞
・In this mode, the plane is not controlled by gyro sensor.
16

GYRO-MODE＜Red＞
・This mode is suitable for inverted
ﬂight and aerobatics.
・The plane is controlled by gyro sensor
only.
・Fuselage attitude angle limit and automatic horizontal level control are
not active.

② Press the GYA460 SET button for atleast 2 seconds to enter the settingmode.
※ When the setting mode is entered,
LED1 lights blue.
③ When the SET button is pressed,
the color of LED1 changes and thesetting item changes.
④ When the SET button is double
clicked, the color of LED2 changes
and the setting is changed.

Aileron, elevator, and rudder gyro gain
adjustment and gyro operating direction are set by flight control trimmer.
The center of the scale becomes thegyro low gain position, and gyro gain
adjustment and gyro operating direction setting are performed by turning
the trimmers to the left or right.

gyro gain trimmers to about 45˚.
② In the state in which the gyros areoperative, move the transmitter
sticks and check that each control
surface moves in the proper
direction. If a control surface moves
in the opposite direction of stick
operation, set transmitter reverse.
③ Without any transmitter input, turnthe model on the aileron, elevator,
and rudder rotating axis direction
and check if each control surface
moves in the direction opposite
the rotating direction (directionin which the plane returns). If thedirection of the steering angle
correction rudder is reversed,change the trimmer to 45˚ of theopposite side.
22

GYRO DIRECTION CHECK
Tilt the airplane to the right on theground and check that the rudder
operates to the left.

Tilt the airplane to the left on theground and check that the ailerons
operate to the right.

Tilt the airplane with its nose upward
and check that the elevator operates
downward.

FLIGHT SETTING
1. Trim setting① Turn on the power in the GYRO OFF-MODE or GYRO-MODE.
② Fly the plane in the GYRO OFF-MODEor GYRO-MODE and adjust thetrimmers.
③ Land the plane and turn off the gyropower.
④ Turn on the gyro power again in theGYRO OFF-MODE or GYRO-MODE. This
memorizes the trim position at thegyro.

2. Flight Gain setting
Adjust the gyro gain so that hunting(deﬂection of the aircraft in small increments)
does not occur in the control axis direction.
The gyro gain is different depending on
the area of the aircraft rudder (aileron/elevator), air speed, and gyro used. Initiallytry changing the gain in 5% steps. If hunting
is excessive, the aircraft may be damaged.
Hunting tends to stop when the airspeed islowered.
25

※ GYA460 mounting angle

For example, if the gyro is mounted facing
upward,in the beginner mode, the nose will tend todrop.

In this case, adjust so that the GYA460 ismounted slightly downward.

TAILLESS WING
This product is compatible with Tailless
wing mixing (elevon). The setting method isdescribed below.

① Set the transmitter in accordancewith page 15. Set the transmittermodel to normal tail 1 aileron.
※ Tailless wing mixing is performedat the gyro.
② Set the gyro to Tailless wing inaccordance with pages 19 and20.
③ After checking plane operation,
make a ﬂight.
