Product overview
The RadioLink R8FGH is an eight-channel receiver for remotely controlled model cars and boats, including FPV applications. Its dual-antenna architecture combines radio reception, a gyro and built-in voltage telemetry. Communication uses FHSS spread spectrum with 67-channel pseudo-random frequency hopping, and ground control distance is specified as up to 600 meters. The supplied package contains the receiver, an engine voltage telemetry connection cable and a packaging bag. The gyro incorporates software filtering and a PID algorithm, with sensitivity adjustable through the PS3 switch.
Electrical integration uses a 3-12V supply, with support for high-voltage servos and protection against reversed power polarity. PWM mode provides eight PWM channels and is identified by a steady green LED or steady green and red LEDs. In combined PWM+SBUS mode, channels 1 through 7 carry PWM and channel 8 carries SBUS, with a steady blue indicator. Nano-coating on the circuit board and pins provides IPX4 splash protection. A subsidiary ID function supports selecting among multiple bound receivers for car or boat rescue and towing applications.
When paired with RC8X, the receiver offers 14ms, 4ms and 3ms servo response settings; displaying this option requires RC8X firmware V1.1.5 or above and selection of FHSS V2. Other transmitters default to 14ms. The recommended setting is 14ms for analog servos and 4ms or 3ms for digital servos. RSSI and receiver voltage display after binding. Model battery voltage monitoring supports a maximum 14S (60V) battery and requires a wire connection to the ESC, battery and receiver telemetry port, without an additional telemetry module.
