Futaba GYA553 Gyro 3 Axis Airplane Instruction Manual

Futaba GYA553 Gyro 3-Axis Airplane

Product Information

The product is a GYA553 gyro system for remote-controlled aircraft. It features gyro operation mode, sensitivity control, and displays battery voltage. It also allows for setting different wing and tail types and servo types for optimal performance.

Product Usage Instructions

1. Make sure the GYA553 is connected to the receiver battery.
2. On the home screen, you can view basic information such as gyro operation mode, sensitivity, and battery voltage.
3. To set the gyro operation mode and gain for the aileron, elevator, and rudder axes, navigate to the corresponding menu options.
4. To view the software version of the connected GYA553, check the GYA553 Software Version menu.
5. To check the battery voltage of the receiver battery connected to GYA, go to the Battery Voltage menu.
6. To set the wing type and tail type, select the appropriate options in the Wing Type/Tail Type menu.
7. To select the servo type according to the servo being used, navigate to the Servo Type menu.
8. For dual aileron, dual elevator, and dual rudder aircraft, make sure to check the operating direction of each second aileron/elevator/rudder in the Dual Aileron/Elevator/Rudder Aircraft menu.
9. To set the direction of the gyro, go to the Gyro Direction Setting menu. Be cautious as reversing the direction can cause crashes.
10. To set the neutral position for each servo, use the Neutral Position Setting menu.

By installing the latest software on the T16IZ/T16IZ SUPER, you can set the airplane gyro GYA553 on the T16IZ/T16IZ SUPER.

Connection T16IZ/T16IZ SUPER and GYA553

CAUTION

• Be sure to connect and disconnect the GYA553 and Transmitter connection cable with the power off.

SETTING

1. Select “Gyro setting” on the last page of the Airplane Model Menu
2. The home screen is displayed

When copying data from Gyro A to Gyro B

• Connect the gyro A to the transmitter and press [Start]. (Enter the data of A into the transmitter)
• Connect Gyro B to the transmitter and press [GY Settings Transfer]. (Put data on A into gyro B)

Home  screen

On the home screen, basic information such as gyro operation mode, sensitivity, and battery voltage are displayed.

Basic menu

Config

Config 1/7Gyro set mounting direction

Set the mounting direction of GYA. Set mounting direction with reference to the figure below.

Config　1/7　WING/TAIL

• Set with the wing type/tail type of GYA553. The wing type/tail type of the transmitter is not used and is normal.
• Turn off the elevon/V-tail mixing on the transmitter side.
• Do not use transmitter sub-trim. Adjust using the gyro neutral offset.
• When using the S.BUS servo, you can also use the neutral offset function of the S.BUS servo setting parameters.

Config 1/7 Servo type

• Select the servo type according to the servo to be used.
• Digital servo → DG: 285 Hz
• Analog servo → AN : 70 Hz
  The stability of the digital-servo mode of a flight increases in order to perform a high-speed control action.

Config　1/7　SB/R2 OUT

Config　2/7 Gyro direction

It is the direction settting of the gyro. Be careful as it will crash if the direction is reversed. For dual aileron, dual elevator, and dual rudder aircraft, check the operating direction of each second aileron/elevator/rudder .

Config　3/7　Neutral offset

Config　4/7　5/7　Servo limit

• This is the limit setting for each servo. The position of the maximum operation is read into the gyro in the first setting.
• If the SB/R2 port output is set to “S.BUS(HS)” or “S.BUS(STD)”, the setting menu will display
• AIL3 and AIL4 setting items.
• AIL3 and AIL4 settings cannot be set with the button settings on the GYA553 main unit.

Aileron example

Config　6/7　Holding Power

• It is a function to adjust the posture-holding force of the aircraft in AVCS mode.
• Decreasing the value weakens the holding power and makes the operation feel closer to the normal mode.
• The current rate numbers C1 to C5 are displayed by operating the channel of the transmitter.
• Like the flight condition function of the transmitter, you can set up to 5 different data for the attitude holding force rate of the aircraft in AVCS mode by operating the switch from the transmitter and switching between them. You can set the holding power rate selector switch to the channel with the AFR function of the transmitter, and set the point for each rate on the AFR point curve to switch. It is also possible to use the flight condition function to work with the flight condition switch.

Config　7/7　Reset

• Reset each Config item. It returns to the initial value.

SBUS Basic menu

Set the CH for each function according to the transmitter to be used. Any unused functions should be set to INH (Inhibited).

WARNING

• Always verify that the S.BUS function assignments match your transmitterʼ’s function (in the FUNCTION menu) assignments.
• If any changes are made within the transmitter function assignments, then it will also be necessary to make the changes within the S.BUS function assignments. To change the channel, GYA553, and T16IZ must be connected.
• CH setting items for AIL3 and AIL4 are displayed on the final screen of the S.BUS basic setting screen. By setting the operation CH of AIL3 and AIL4, the gyro-controlled signal is output to the corresponding CH of the S.BUS output.
• Match the operation CH and CH settings on the function setting screen on the transmitter side.
• When the AIL3 and AIL4 CH settings are INH, the gyro control is not performed and the data sent from the transmitter is output as is.
