• S.Bus/GAIN: Port for S.Bus receiver connection or master gain adjustment.
• MODE: Input for flight mode channel from receiver.
• RUD, ELE, AIL: Input channels for Rudder, Elevator, and Aileron from receiver.
• GAIN1 (Normal Gain): Adjusts gain for Normal mode.
• GAIN2 (Auto-balance Gain): Adjusts gain for Auto-balance mode.
• GAIN3 (Auto-hover Gain): Adjusts gain for Auto-hover mode.

Setup and Installation

Mounting the Controller

The A3 V2 series can be attached flat or upright to maximize space utilization within your aircraft. Use the provided double-sided adhesive pads for secure mounting.

Wiring Connections

The A3 V2 series provides 5-channel inputs and 3-channel outputs. You need to connect the receiver and servos to the corresponding pins on the side of the controller.

Standard Receiver Wiring:

1. Connect Rudder Servo to OUT3.
2. Connect Elevator Servo to OUT2.
3. Connect Aileron Servo to OUT1.
4. Connect receiver channels to AIL, ELE, RUD, MODE, and GAIN inputs on the A3 V2.
5. Connect the throttle channel from the receiver directly to the ESC/Throttle Servo.

Futaba S.Bus Wiring:

1. Connect the S.Bus output from your receiver to the S.Bus/GAIN port on the A3 V2.
2. The A3 V2 will then output to OUT1 (Aileron), OUT2 (Elevator), OUT3 (Rudder).
3. Connect the throttle channel from the receiver directly to the ESC/Throttle Servo.

Note: Futaba S.Bus and S.Bus 2 are supported by the new A3 series.

Automatic Stick Centering

The controller supports automatic stick centering. Ensure your transmitter sticks are centered before initial power-up or calibration.

Operation

Flight Modes

The A3 V2 offers four distinct flight modes:

• Normal Mode: Standard stabilization, providing assistance without overriding pilot input.
• Auto-balance Mode: Designed for beginners or FPV applications, the controller automatically helps the plane achieve and maintain level flight. It can also assist in recovering the plane from unusual attitudes and aid in stable takeoffs and landings.
• Auto-hover Mode: A new flight mode where the self-balance ability is applied to both elevator and rudder. The plane can hold its hover attitude without any control except the throttle. This mode simplifies hover practice.
• Gyro Off Mode: Disables the gyroscope stabilization, allowing for direct control without assistance.

One-click Hover and Auto-hover

When operating in Auto-hover mode, the plane can maintain its hover attitude with minimal input. You only need to control the throttle to maintain sufficient thrust.

Auto-balance Level Flight

This mode is particularly useful for beginners. The controller actively stabilizes the aircraft to maintain a level flight attitude, simplifying control and recovery.

Gain Adjustment

The knobs on the controller (GAIN1, GAIN2, GAIN3) are used to adjust the gain for each flight mode. Turn clockwise to increase gain and counter-clockwise to decrease gain. Adjusting gain fine-tunes the sensitivity of the stabilization system.

A3 V2 Settings Menu

The A3 V2 offers various settings configurable via the SET button and LED indicators. Refer to the table below for a summary of settings.

Maintenance

The A3 V2 Flight Stabilizer is designed for durability and reliability. Minimal maintenance is required:

• Keep the unit clean and free from dust and debris.
• Ensure all connections are secure before each flight.
• Avoid exposing the unit to extreme temperatures or moisture.
• Regularly check the adhesive mounting for secure attachment.

Troubleshooting

If you encounter issues with your A3 V2 Flight Stabilizer, consider the following:

• No power/LEDs off: Check input voltage (5-7.4V) and wiring connections.
• Unstable flight: Adjust gain settings. Ensure the unit is securely mounted and correctly oriented. Perform Level and Vertical Calibration if necessary.
• Incorrect servo response: Verify servo direction settings (Normal/Reversed) in the A3 V2 settings menu. Check receiver type and servo frequency settings.
• No response from controls: Ensure all receiver channels are correctly connected to the A3 V2 inputs. Check transmitter and receiver functionality.
