Setup and Binding
Installation
- Mount the FS-BS6 receiver securely in your RC car or boat model, ensuring it is protected from vibrations and moisture.
- Position the antenna away from metal parts and other electronic components to maximize signal reception. Ensure the antenna is extended as much as possible.
- Connect your servos, ESC, and other components to the corresponding channels (CH1-CH6) on the receiver. Refer to your model's specific wiring diagram.
- Connect the power source (4.0-8.4V DC) to the receiver. Ensure correct polarity.
Binding Procedure (AFHDS2A System)
The FS-BS6 receiver is compatible with FlySky FS-GT5 and FS-IT4S transmitters using the AFHDS2A system. Follow these steps to bind the receiver to your transmitter:
- Ensure your transmitter is turned off.
- Connect a bind plug (not included, typically comes with the transmitter or sold separately) to the 'BIND' port on the FS-BS6 receiver.
- Apply power to the receiver (4.0-8.4V DC). The receiver's LED should start flashing rapidly, indicating it is in binding mode.
- While holding the BIND button on your FlySky transmitter (e.g., FS-GT5 or FS-IT4S), turn on the transmitter.
- Release the BIND button on the transmitter once the transmitter's screen indicates binding is in progress or successful.
- The receiver's LED should stop flashing and remain solid, indicating a successful bind.
- Turn off the receiver, then turn off the transmitter.
- Remove the bind plug from the receiver.
- Turn on the transmitter first, then power on the receiver. The receiver should now be linked and ready for operation.
- Test all channels to ensure proper function before operating your model.
Operating the Gyroscope Function
The FS-BS6 receiver features a built-in gyroscope designed to assist with stability and automatic recovery from unexpected offsets, particularly useful in RC car and boat applications. The gyroscope helps maintain directional stability by counteracting unwanted movements.
Gyroscope Calibration and Adjustment
- Initial Calibration: After binding and powering on the receiver, place your model on a flat, stable surface. The gyroscope will typically self-calibrate upon power-up. Avoid moving the model during this initial phase.
- Sensitivity Adjustment: The gyroscope sensitivity can usually be adjusted via a dedicated channel on your compatible FlySky transmitter (e.g., FS-GT5 or FS-IT4S). Refer to your transmitter's manual for specific instructions on how to assign and adjust gyroscope sensitivity.
- Directional Correction: If the gyroscope corrects in the wrong direction (e.g., steering left when the model drifts right), you may need to reverse the gyroscope direction setting on your transmitter. Consult your transmitter's manual for this adjustment.
Experiment with different sensitivity settings in a safe area to find the optimal balance between stability assistance and natural control feel for your specific model and driving conditions.
Maintenance
- Keep the receiver clean and free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning.
- Regularly inspect all wiring and connections for signs of wear or damage. Replace any damaged components immediately.
- Ensure the antenna is not kinked or damaged, as this can affect signal range and reliability.
- Store the receiver in a dry, cool environment when not in use.
Troubleshooting
- Receiver not binding:
- Ensure the bind plug is correctly inserted. Verify the transmitter is in binding mode and compatible (AFHDS2A system). Check receiver power supply (4.0-8.4V DC).
- Loss of signal or short range:
- Check antenna placement and ensure it is not obstructed or damaged. Avoid operating near large metal objects or other 2.4GHz interference sources. Ensure transmitter batteries are fully charged.
- Gyroscope not functioning correctly:
- Ensure the model is stationary during power-up for initial calibration. Check gyroscope sensitivity and direction settings on your transmitter. Refer to your transmitter's manual for detailed gyroscope setup.
- Intermittent control:
- Inspect all servo and ESC connections to the receiver. Check for loose wires or damaged pins. Ensure the power supply to the receiver is stable and within the specified voltage range.
