Product overview
The RadioLink R8XM is an eight-channel receiver for integration into FPV drones and other radio-controlled aircraft. Its compact architecture combines control reception with built-in telemetry for RSSI, receiver voltage and model voltage. Measuring 22 × 17 mm and weighing 3 g, it occupies little installation space. Simultaneous SBUS and PPM outputs provide connections to flight controllers including PIX6, PIXHAWK, the CrossFlight series, Mini Pix, APM, F4 and F7. Its radio link uses FHSS spread spectrum with 67-channel pseudo-random frequency hopping.
The supplied configuration contains one R8XM receiver, one engine voltage telemetry connection cable and one packing bag. Battery voltage monitoring requires connecting the battery balance plug to the receiver port and supports 2S–6S (7.4–25.2 V) batteries, without an additional telemetry module. Control distance is specified as 4000 meters*, with telemetry reaching up to the same distance. With T8FB/T8S Bluetooth transmitters, alarm thresholds can be configured through phone and PC apps; distinct audible patterns identify low transmitter, receiver or model voltage and low RSSI.
