[Excellent Anti-interference]: With 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 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 , Mini Pix, TURBO PiX, , F4, F7 etc; Combined with the image transmission camera and FPV display screen/ FPV goggles, to realize long-distance interesting driving.
