6-Axis Flight Control Instruction Manual
Thank you for purchasing the GYA460. 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. INTRODUCTION The GYA460 is a flight attitude controller and stabilizer designed exclusively for model aircraft. In addition to control by 3 axis gyro VHQVRU ÀLJKW DWWLWXGH LV FRQWUROOHG E\ D 3 axis G-sensor.
FEATURES ● Low profile, small size and light weight. ● Easy setup ● S.BUS compatible. Only one connection is necessary between the S.BUS receiver and GYA460. ● Three flight modes can be selected by 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 stalled state in which the rudder is ineffective.
SPECIFICATIONS ● Gyro sensor: MEMS vibrating structure gyro ● Operating voltage：DC4.0 ∼ 8.

PRECAUTIONS 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 adjustment stage and decide the number of flights with a margin to spare. Always check the direction of operation of the gyro. ■ Attempting to fly with the operating direction reversed is extremely dangerous.
■ 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 other applications. The GYA460 assists flight by beginners. However, this does not mean that RC model aircraft can be flown alone by a completely inexperienced flyer. Inexperienced flyers should fly safely under the guidance of an instructor.

MOUNTING to the AIRPLANE Firmly stick the gyro to the chassis with the double 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 the gyro facing forward in the fuselage. *Depending on the airframe material such as balsa, etc., the adhesive strength of the double sided tape may drop.
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 and AIL2 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 servos move.
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 flight training of beginners. ・Control is implemented by gyro sensor and acceleration sensor. ・The fuselage flight attitude angle is limited to approximately ± 80° . ・When the transmitter sticks (except the 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%.
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. ◆ When the transmitter has no 3-position switch.

2. GYRO setting The parameters can be set by GYA460 SET button. ① Turn on the GYA460 power. ② Press the GYA460 SET button for at least 2 seconds to enter the setting mode. ※ When the setting mode is entered, LED1 lights blue. ③ When the SET button is pressed, the color of LED1 changes and the setting item changes. ④ When the SET button is double clicked, the color of LED2 changes and the setting is changed. ⑤ When the SET button is pressed for at least 2 seconds, the setting mode ends.

3. Gyro Gain and Direction Aileron, elevator, and rudder gyro gain adjustment and gyro operating direction are set by flight control trimmer. The center of the scale becomes the gyro low gain position, and gyro gain adjustment and gyro operating direction setting are performed by turning the trimmers to the left or right.
PRE-FLIGHT SETTING ① Set the aileron, elevator, and rudder gyro gain trimmers to about 45̊. ② In the state in which the gyros are operative, 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.
GYRO DIRECTION CHECK Tilt the airplane to the right on the ground and check that the rudder operates to the left.
Tilt the airplane to the left on the ground 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 setting ① Turn on the power in the GYRO OFF -MODE or GYRO-MODE. ② Fly the plane in the GYRO OFF-MODE or GYRO-MODE and adjust the trimmers. ③ Land the plane and turn off the gyro power. ④ Turn on the gyro power again in the GYRO OFF-MODE or GYRO-MODE. This memorizes the trim position at the gyro. 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.
※ GYA460 mounting angle For example, if the gyro is mounted facing upward, in the beginner mode, the nose will tend to drop. In this case, adjust so that the GYA460 is mounted slightly downward.
TAILLESS WING This product is compatible with Tailless wing mixing (elevon). The setting method is described below.
① Set the transmitter in accordance with page 15. Set the transmitter model to normal tail 1 aileron. ※ Tailless wing mixing is performed at the gyro. ② Set the gyro to Tailless wing in accordance with pages 19 and 20. ③ After checking plane operation, make a flight.
