RadioMaster ER8G 2.4GHz ELRS 8CH PWM Receiver

The RadioMaster ER8G is a slimline 2.4GHz ELRS receiver purpose-built for fixed-wing aircraft, gliders, and traditional RC models requiring direct PWM servo outputs. Designed to slide easily into tight carbon fibre fuselages, it delivers the low latency and extended range of the ExpressLRS protocol in a narrow 13.5mm profile.

Key features

• True diversity dual-antenna system maintains a robust, multi-directional signal link during banked turns.

• Eight standard PWM outputs to drive servos and ESCs directly without requiring a flight controller.

• Supports up to 100mW telemetry power for continuous data return over long distances.

• Dedicated EXTV telemetry pad directly monitors your primary flight battery voltage (up to 35V).

• Compact, glider-optimised footprint prevents wiring bottlenecks in narrow airframes.
