5.2 Connecting the Receiver

1. Power Connection: Connect the receiver to a stable power source within the specified input voltage range of 4-8.4V.
2. Signal Output: Connect the receiver to your flight controller using the appropriate signal type (PWM, I.BUS, or PPM). Refer to your flight controller's manual for specific wiring diagrams.
3. Voltage Detection: If you wish to utilize the two-way transmission for battery voltage detection, connect the voltage detection cable to the designated port on the receiver and to the battery or a voltage sensing pad on your drone. The receiver supports 1-4S voltage detection.
4. Antenna Placement: Securely attach both antennas to the receiver. For best signal reception, ensure the antennas are positioned at a 90-degree angle to each other and are clear of carbon fiber or metal obstructions.

5.3 Binding Process

To establish communication between the FS-X6B receiver and your Flysky transmitter, a binding process is required. While specific steps may vary slightly depending on your transmitter model, the general procedure is as follows:

1. Ensure both your transmitter and receiver are powered off.
2. Connect a bind plug (often included with transmitters or receivers) to the B/VCC port on the FS-X6B receiver.
3. Power on the receiver. The receiver's LED indicator should start flashing rapidly, indicating it is in binding mode.
4. While holding the bind button on your Flysky transmitter (or following its specific binding procedure), power on the transmitter.
5. The receiver's LED should turn solid, indicating a successful bind.
6. Power off both the receiver and transmitter. Remove the bind plug from the receiver.
7. Power on the transmitter first, then the receiver. The receiver's LED should immediately turn solid, confirming the bind is active.

If the binding is unsuccessful, repeat the steps. Ensure your transmitter is set to the AFHDS 2A protocol if it has multiple options.

6. Operating Instructions

Once the FS-X6B receiver is successfully bound to your Flysky transmitter and connected to your FPV racing drone, operation is straightforward:

• Power On Sequence: Always power on your transmitter first, then power on the drone (and thus the receiver). When powering off, disconnect the drone's battery first, then power off the transmitter.
• Signal Reception: The receiver will automatically establish a connection with the bound transmitter. The solid LED on the receiver indicates a stable connection.
• Control Input: The receiver translates the control signals from your transmitter into commands for the flight controller, allowing you to control your drone.
• Battery Voltage Telemetry: If the voltage detection cable is connected, your transmitter (if it supports telemetry display) will show the real-time battery voltage of your drone. Monitor this value to ensure safe flight times and prevent over-discharging.

7. Maintenance

To ensure the longevity and reliable performance of your FS-X6B receiver, consider the following maintenance tips:

• Handle with Care: The receiver is a delicate electronic component. Avoid dropping it or subjecting it to strong impacts.
• Keep Dry: Protect the receiver from moisture and water exposure, as this can cause irreparable damage to the electronics.
• Cleanliness: Keep the receiver free from dust, dirt, and debris. Use a soft, dry brush or compressed air for cleaning if necessary.
• Antenna Integrity: Regularly inspect the antennas for any signs of damage (e.g., kinks, cuts). Damaged antennas can significantly reduce signal range and reliability.
• Secure Mounting: Ensure the receiver is securely mounted within your drone to prevent vibrations or movement from damaging connections or the unit itself.

8. Troubleshooting

If you encounter issues with your FS-X6B receiver, refer to the following common problems and solutions:
