The Radiolink R8FM is an 8-channel 2.4GHz micro RC receiver designed for mini FPV racing drones, quads, and aircraft. It features SBUS/PPM signal output and utilizes frequency hopping spread spectrum (FHSS) pseudo-random algorithm for strong anti-interference capabilities. Its compact size and lightweight design make it ideal for small-scale models.
- Strong Anti-interference: Employs FHSS technology for reliable signal reception.
- 8 Iziteshi: Provides standard SBUS/PPM signal output with a high resolution ratio of 4096 for fast response.
- Ukulawulwa Kwebanga Elide: Offers stable remote control distance up to 1.2 miles in the air (actual distance may vary with environment).
- I-Super Mini size: Weighs only 0.09oz (2.5 grams) and measures 0.78*0.59*0.2 inches, suitable for drones like 130, 120, 110.
- Easy to Bind and Safe Protection: Binds in approximately 1 second to T8S/T8FB transmitters. Includes voltage protection software.

2.3 Inqubo Yokubopha
Follow these steps to bind your R8FM receiver to a compatible Radiolink transmitter:
- Ensure your transmitter is powered on and in binding mode (refer to your transmitter's manual for specific instructions).
- Connect the R8FM receiver to a power source (typically +5V from your flight controller or an external BEC).
- Cindezela bese ubamba i I-ID SET button on the R8FM receiver.
- While holding the button, power on the receiver. The LED on the receiver should start flashing rapidly, indicating it is in binding mode.
- Dedela inkinobho ye-ID SET.
- Once the binding is successful, the LED on the receiver will turn solid blue (for SBUS) or solid red (for PPM), indicating a stable connection.
The binding process typically takes about 1 second.
3. Operating Modes and Signal Output
3.1 SBUS/PPM Signal Switching
The R8FM receiver supports both SBUS and PPM signal outputs. You can switch between these modes by quickly pressing the I-ID SET button twice after the receiver has successfully bound.
- I-LED Ebomvu: Indicates PPM signal output (8 Channels Working).
- I-LED Ensomi: Indicates SBUS signal output (8 Channels Working).

3.2 Integration with Flight Controllers
The R8FM receiver needs to be equipped with a flight controller that supports SBUS or PPM input. Ensure your flight controller is configured correctly for the chosen signal type.

4. Isondlo
To ensure the longevity and optimal performance of your Radiolink R8FM receiver, follow these general maintenance guidelines:
- Gcina Komile: Avoid exposing the receiver to moisture or humidity, as this can damage internal electronic components.
- Hlanza ngobumnene: If cleaning is necessary, use a soft, dry cloth. Do not use liquid cleaners or solvents.
- Vikela Kumthelela: While durable, avoid dropping the receiver or subjecting it to strong impacts.
- Isitoreji Esifanelekile: Store the receiver in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Ukunakekelwa kwe-Antenna: Ensure the antenna is not bent sharply or damaged, as this can affect signal reception range.
5. Ukuxazulula izinkinga
If you encounter issues with your R8FM receiver, consider the following common problems and solutions:
| Inkinga | Imbangela Engenzeka | Isixazululo |
|---|---|---|
| Receiver LED not lighting up. | No power or incorrect power connection. | Check power supply (+5V) and ensure correct polarity. |
| Receiver LED flashing rapidly, not binding. | Transmitter not in binding mode or too far away. | Ensure transmitter is in binding mode and bring receiver closer to transmitter. Re-attempt binding. |
| No control response after binding. | Incorrect signal output (SBUS/PPM) or flight controller configuration. | Double-check receiver LED color (Red for PPM, Purple for SBUS) and ensure flight controller is set to match. Verify wiring to flight controller. |
| Reduced range or intermittent signal. | Antenna damage or interference. | Inspect antenna for damage. Ensure antenna is not shielded by carbon fiber or metal. Avoid operating near strong interference sources. |
