4. Setup
4.1. Binding Procedure (Transmitter and Receiver)
The FLYSKY transmitter and receiver are typically pre-bound before delivery. If you are using another transmitter or receiver, or if binding is lost, follow these steps:
- Connect the supplied bind cable to the B/VCC port on the receiver.
- Insert power into any other port on the receiver.
- Hold the "BIND KEY" on the transmitter while powering it on to enter bind mode.
- Once binding is successful, remove the power and bind cable from the receiver.
- Then, connect the power cable to the B/VCC port for normal operation.
- Check the servos' operation. If anything does not work as expected, restart this procedure from the beginning.

4.2. Powering the Transmitter
The FS-i6 Transmitter requires 6V power, typically supplied by 4 AA batteries (not included). Ensure batteries are inserted with correct polarity.
5. Operating Instructions
The FS-i6 system utilizes a 2.4GHz AFHDS 2A (Automatic Frequency Hopping Digital System 2A) and AFHDS system, providing reliable communication with low power consumption.
- Channels: 6 CH for various control functions.
- RF Range: 2.40-2.48GHz with 500KHz bandwidth.
- RF Power: Less than 20dBm.
- Code Type: GFSK (Gaussian Frequency Shift Keying).
- Sensitivity: 1024.
- Display: Transflective STN positive type, 128*64 dot matrix VA73*39mm, with white backlight for clear visibility.
- On-line Update: The system supports online firmware updates.
- Control Range: Up to 500m under optimal conditions.
5.1. Unique ID and Interference Immunity
Each transmitter has a unique ID. When binding with a receiver, the receiver saves that unique ID and will only accept data from that specific transmitter. This feature significantly reduces the risk of interference from other transmitters and enhances operational safety.
5.2. Antenna System
The radio system incorporates a high-gain, high-quality multi-directional antenna that covers the entire frequency band. Coupled with a high-sensitivity receiver, this ensures a jamming-free and long-range radio transmission.

6. Maintenance
- Keep the transmitter and receiver clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Store the unit in a cool, dry place away from direct sunlight and extreme temperatures.
- Remove batteries from the transmitter if it will not be used for an extended period to prevent leakage.
- Avoid exposing the components to moisture or corrosive substances.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Servos not responding or erratic behavior after power-on. | Binding issue between transmitter and receiver. | Re-perform the binding procedure as described in Section 4.1. Ensure all steps are followed correctly. Refer to Video 4.1 for a visual guide. |
| Transmitter not powering on or low power warning. | Low battery voltage or incorrect battery installation. | Check battery polarity and replace with fresh 4 AA batteries if voltage is below 4.2V (low voltage warning threshold). |
| Limited control range or signal loss. | Environmental interference or antenna obstruction. | Ensure clear line of sight between transmitter and receiver. Avoid operating near large metal objects or other 2.4GHz devices. Check receiver antenna placement. |
