Radiolink R8XM 2.4GHz 8CH FHSS SBUS/PPM Mini Receiver Built-in Telemetry 4000M Control Distance for RC Airplane Car Boat -R8XM Specifications: Brand: RadioLink Model: R8XM Channel:8 Size: 22*17mm Weight: 4g Signal Output: SBUS/PPM Operating Voltage: 3-6V DC Operating Current: 40mA±5mA@5V Model Telemetry Voltage: 2S-6S LiPo battery Control Distance: 4000 meters (2.49Miles) in air (Maximum range tested in unobstructed areas free of interference and may vary depending on local regulations). Telemetry Distance:The same with control distance Adaptable Models: Racing Drone/Rotary Wing/ Fixed Wing/ Glider/ Multicopter/ Car/ Boat/ Robot (must work with flight controller). Output Frequency: 2.4GHz ISM band（2400MHz~2483.5MHz） Spread Spectrum: FHSS, 67 channels pseudo-random frequency hopping -Features: --Excellent Anti-interference: With pseudo random FHSS algorithm, R8XM has excellent anti-interference ability, highly constant, and stable transmission signal present on all 8 channels. --Long Range Control: The maximum tested control distance up to 4000 meters in the air in an unobstructed area free of interference. --Real-time Telemetry: Support telemetry real-time vital information like vehicle's battery voltage(2S-6S LiPo battery), RSSI signal and receiver voltage to the radio screen, avoiding the battery over-discharge and damage. --Compatible with Multiple Models: The mini size and lightweight make it perfect for mini racing drone and glider. It’s also compatible with rotary wing, fixed wing, multi-rotor, car, boat and robot when working with flight controller. --Work Well with FPV Device: Compatible with flight controllers such as P1XHAWK, Mini P1x, TURBO P1X, APM, F4, F7 etc; Combined with the image transmission camera and FPV display screen/ FPV goggles, to realize long-distance interesting driving. -Package Included: 1x R8XM receiver 1x Telemetry cable Please don't put the R8XM receiver at closer distance with radio, otherwise it will hard to complete the binding and it is easy to cause signal loss.
