Product Overview
The RadioLink R7EH is a compact and reliable 7-channel 2.4GHz receiver designed for use with RadioLink T6EAP, T6EHP, and T7F series transmitters. It utilizes advanced 2.4GHz technology to provide stable and interference-free control for various RC models.
Key Features:
- 7-Channel output for comprehensive control.
- 2.4GHz frequency hopping spread spectrum (FHSS) technology.
- Compact and lightweight design.
- Compatible with specific RadioLink transmitters.
Setup Instructions
1. Binding the Receiver to the Transmitter:
- Ensure both your transmitter (T6EAP, T6EHP, or T7F) and receiver are powered off.
- Connect a bind plug (not included, typically comes with the transmitter or flight controller) to the BIND/VCC port on the R7EH receiver.
- Power on the receiver. The LED indicator on the receiver should start flashing rapidly, indicating it's in binding mode.
- While holding down the bind button on your transmitter (refer to your transmitter's manual for exact location), power on the transmitter.
- The LED on the receiver should turn solid, indicating a successful bind.
- Release the bind button on the transmitter and power off both the receiver and transmitter.
- Remove the bind plug from the receiver.
- Power on the transmitter first, then the receiver. The receiver's LED should be solid, confirming the connection.
2. Connecting Servos and ESC:
Connect your servos, Electronic Speed Controller (ESC), and other components to the corresponding channels on the receiver. Pay close attention to the polarity markings on the receiver ports.
Figure 2: Receiver port details showing polarity (Л+-) for correct connection.
- Signal (S): Typically the top pin, usually white or yellow wire.
- Positive (+): Middle pin, usually red wire.
- Negative (-): Bottom pin, usually black or brown wire.
Incorrect polarity can damage the receiver or connected components.
Operating Instructions
- Always power on your transmitter first, then your receiver.
- After powering on the receiver, ensure the LED indicator is solid, confirming a stable connection to the transmitter.
- Test all control surfaces and functions before operating your RC model.
- Always power off your receiver first, then your transmitter, to prevent accidental movements or loss of control.
Range and Interference:
The 2.4GHz system offers excellent range and interference resistance. However, always perform a range check before flying, especially in new environments. Avoid operating near large metal objects, power lines, or other strong radio frequency sources that could interfere with the signal.
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 all wiring and connections for signs of wear or damage.
- Ensure the antenna is not cut, bent sharply, or obstructed, as this can significantly reduce range.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Receiver LED not solid after binding/power-on | Not bound, out of range, or interference. | Re-perform binding procedure. Ensure transmitter is on and close to receiver. Check for strong interference sources. |
| No response from servos/ESC | Incorrect wiring, power issue, or faulty component. | Check all connections for correct polarity and secure fit. Verify power supply to receiver and components. Test components individually if possible. |
| Reduced range or intermittent signal | Damaged antenna, interference, or low transmitter/receiver battery. | Inspect receiver antenna for damage. Avoid operating near known interference sources. Ensure batteries are fully charged. |

User Tips
- Antenna Placement: For optimal signal reception, ensure the receiver antenna is positioned away from carbon fiber, metal parts, and other electronics. Try to orient the antenna at a 90-degree angle to the other antenna (if applicable) or away from large conductive surfaces.
- Power Source: Always use a stable and appropriate power source for your receiver, typically provided by the ESC's BEC or a dedicated UBEC. Verify the voltage is within the receiver's operating range.
- Pre-Flight Checks: Before each use, perform a thorough pre-flight check, including range testing and verifying all control surfaces respond correctly and in the right direction.
