• Compatible with Futaba FASST 2.4GHz systems, including ground systems such as 3PK and 4PK.
• Can be used in parallel with other TFR8/TFR8-S receivers to achieve 14-channel FASST compatibility.
• Firmware upgradable for future enhancements and compatibility.
• Supports all FrSky 2.4GHz systems, including ground systems and FrSky TF Modules (TF-8M, TF-14M).
• Features SB (S.BUS) and RSSI (Received Signal Strength Indication) capabilities.

3. Setup

3.1. Compatibility

The FrSky TFR8-S receiver is designed for compatibility with Futaba FASST 2.4GHz air systems and ground systems (e.g., 3PK, 4PK). It also works with all FrSky 2.4GHz systems, including FrSky TF Modules (TF-8M, TF-14M).

3.2. Binding Procedure

To establish a connection between your receiver and transmitter, follow the binding instructions specific to your Futaba FASST or FrSky 2.4GHz transmitter module. Generally, this involves:

1. Powering on your transmitter in binding mode.
2. Powering on the receiver while holding its F/S (Fail-Safe) button.
3. Observing the LED indicator on the receiver for successful binding confirmation (refer to your transmitter's manual for specific LED patterns).
4. Once bound, power cycle both the transmitter and receiver to confirm the connection.

3.3. Channel Expansion (14-Channel Mode)

For applications requiring more than 8 channels, the TFR8-S can be used in parallel with another TFR8 or TFR8-S receiver to achieve 14-channel FASST compatibility. Consult advanced setup guides for detailed wiring and configuration for this mode.

4. Operating Instructions

Once successfully bound, the receiver will provide an 8-channel output. Ensure all connections to servos, ESCs, and other components are secure and correctly oriented before powering your model.

• Power Supply: The receiver operates within a voltage range of 4.0V to 10.0V. Ensure your power source (e.g., BEC, dedicated receiver battery) provides stable voltage within this range.
• Latency: The receiver offers low latency performance: 14ms in FS (Full Speed) mode and 7ms in HS (High Speed) mode, providing responsive control.
• S.BUS: Utilize the S.BUS port for simplified wiring with S.BUS compatible servos and devices, reducing cable clutter.
• RSSI: The RSSI output provides real-time information on the received signal strength, which can be used with compatible flight controllers or OSDs for telemetry.

5. Maintenance

• Keep the receiver clean and free from dust, dirt, and moisture.
• Avoid exposing the receiver to extreme temperatures or direct sunlight for prolonged periods.
• Regularly inspect antenna wires for damage and ensure they are properly positioned for optimal signal reception.
• Ensure all connections are secure before each use.
• Store the receiver in a dry, cool place when not in use.

6. Troubleshooting

• No Signal/Loss of Control:
  • Verify the receiver is correctly bound to the transmitter.
  • Check power supply to the receiver and ensure it's within the operating voltage range.
  • Inspect antenna connections and ensure they are not damaged or obstructed.
  • Ensure the transmitter battery is charged.
• Intermittent Signal:
  • Check for sources of interference (e.g., other 2.4GHz devices, carbon fiber structures, metal objects).
  • Reposition antennas for better line-of-sight to the transmitter.
  • Ensure the receiver is not mounted too close to high-current components (ESCs, motors).
• Servos Not Responding:
  • Confirm servos are correctly plugged into the receiver's channel ports.
  • Check servo power supply.
  • Test servos individually to rule out faulty components.
