Details

RadioLink R8FGH 8-channel dual antenna receiver delivers a 3ms response time and real-time telemetry for up to 14S (60V) battery voltage. It supports 3-12V input, works with high-voltage servos, and offers Blue/Purple-S.BUS+PWM protocols. Waterproof (IPX4) and certified with CE, FCC, and RoHS, this receiver ensures reliable performance for diverse remote control applications. Made in China.

The FHSS system features advanced anti-interference technology and 67 frequency channels. This ensures reliable communication for multiplayer gaming, preventing interference from fuel-powered model cars' engine sparks and guaranteeing a safe playing experience.

RadioLink R8FGH 8CH Receiver offers 3ms response speed. Select servo speed (14ms, 4ms, 3ms) based on connection type. Update RC8X firmware to V1.1.5 for FHSS V2 protocol compatibility.


Customizable gyro sensitivity enhances stability through software filters and PID algorithms. Adaptable to various models and applications, it delivers professional performance, even with drift cars. Sensitivity adjustments via the PS3 switch optimize functionality. Demonstrations show improved control and smoother operation, both in straight paths and circular tracks, compared to systems without gyro integration.

Real-time telemetry tracks model battery voltage and RSSI data. Connect wires to ESC, battery, and receiver Telemetry port for display. Supports up to 14S (6V) batteries without extra modules.

PWM and SBUS Signal-supported. PWM mode: Green LED indicates 8-channel signal output. PWM+SBUS mode: Blue LED for combined signals. CH1-CH7 PWM, CH8 SBUS. Personalize for FPV model fun.

RadioLink R8FGH 8CH Receiver, waterproof (IPX4), with nano-coating technology. Supports Blue/Purple/IBUS/PWM, 3.0-12V/DC. Made in China. Features CE and RoHS compliance.
