6. Setup

6.1 Physical Connection

1. Connect Servos: Plug your servos into the corresponding channel ports (CH1-CH8) on the receiver. Ensure correct polarity (signal, positive, negative).
2. Power Connection: Connect the power source (e.g., ESC's BEC, separate receiver battery) to any available channel port or the BIND/BAT port. Ensure the voltage is within the specified range of 4.0-6.5V.
3. Antenna Placement: Position the receiver antenna away from metal parts and other electronic components to maximize signal reception. The antenna should be as straight as possible.

6.2 Binding Procedure

Binding is the process of linking the receiver to your transmitter, establishing a unique communication link.

Figure 3: A standard bind plug used for initiating the binding process on Flysky receivers.

1. Ensure your transmitter is turned OFF.
2. Insert the bind plug into the BIND/BAT port on the FS-R9B receiver.
3. Connect power to the receiver. The receiver's LED should start flashing rapidly, indicating it is in binding mode.
4. Turn on your transmitter while holding down the bind button (or following your transmitter's specific binding instructions).
5. The receiver's LED should stop flashing and become solid, indicating a successful bind.
6. Release the bind button on the transmitter (if applicable) and turn off the receiver's power.
7. Remove the bind plug from the receiver.
8. Turn on the transmitter first, then power on the receiver. The receiver's LED should be solid, confirming the connection.

Note:

• Always turn on your transmitter before powering on your model, and turn off your model before turning off your transmitter.
• If the binding process fails, repeat the steps. Ensure the transmitter and receiver are within close proximity during binding.

7. Operating

Once the receiver is successfully bound to your transmitter, it will receive control signals and translate them into commands for your model's servos and other connected components. Ensure all control surfaces and functions respond correctly to your transmitter inputs before operating your model.

• Range Check: Before each flight or operation, perform a range check according to your transmitter's manual to ensure adequate signal strength.
• Fail-Safe: Configure fail-safe settings on your transmitter to ensure your model reacts predictably (e.g., throttle to idle, control surfaces neutral) in case of signal loss.

8. Maintenance

Proper maintenance ensures the longevity and reliable performance of your FS-R9B receiver.

• Keep Clean: Regularly clean the receiver and its connections, ensuring no dust, dirt, or moisture accumulates.
• Protect from Vibration: Mount the receiver using foam or double-sided tape to isolate it from excessive vibrations.
• Avoid Moisture: Protect the receiver from water and high humidity. If operating in damp conditions, consider using a waterproof enclosure.
• Inspect Connections: Periodically check all wire connections for wear, damage, or loose contacts.

9. Troubleshooting

If you encounter issues with your FS-R9B receiver, refer to the following common problems and solutions:

• No Signal / Receiver LED Not Solid:
  • Ensure the receiver is powered correctly (4.0-6.5V).
  • Verify the receiver is properly bound to the transmitter. Repeat the binding procedure if necessary.
  • Check that the transmitter is turned ON and fully charged.
  • Ensure the transmitter and receiver are compatible (refer to Section 5).
• Erratic Servo Movement:
  • Check for interference from other electronic devices.
  • Inspect servo connections for looseness or damage.
  • Ensure the receiver's power supply is stable and sufficient.
• Limited Range:
  • Check antenna placement; ensure it is not obstructed or damaged.
  • Avoid operating near large metal objects or strong RF interference sources.
  • Ensure the transmitter's antenna is fully extended and undamaged.
