Radiomaster ER8 2.4GHz ELRS PWM Receiver
Introducing the RadioMaster ER8, the ultimate ExpressLRS (ELRS) receiver designed specifically for fixed-wing pilots. This receiver combines the incredible range and performance of the ELRS system with the multi-channel PWM output needed for traditional RC planes and FPV wings. Featuring 8 PWM channels, powerful 100mW telemetry, and a true diversity antenna setup, the ER8 provides a rock-solid, long-range control link for your aircraft.
The Perfect Receiver for FPV Wings & Planes
The ER8 is purpose-built for the fixed-wing enthusiast. With 8 dedicated PWM output channels, it can easily control all the components of a traditional aircraft, including throttle, ailerons, elevator, rudder, flaps, and landing gear, without needing extra converters or complex wiring. It’s the perfect way to bring the modern performance of the ELRS ecosystem to your favorite plane.
Powerful Long-Range Performance
Engineered for a robust connection, the ER8 features a true diversity antenna system with two high-sensitivity antennas. A standout feature is its powerful, adjustable 100mW telemetry output, which ensures you receive vital flight data like battery voltage and link status back at your radio, even on long-range flights. For ultimate convenience, firmware can be updated easily via WiFi.
Built-in Voltage Telemetry
This receiver simplifies your electronics setup. It has a built-in sensor to monitor your main flight battery’s voltage (up to 35V / 8S) and automatically sends this information back to your radio. This allows for critical battery monitoring without needing a full flight controller, making it ideal for simpler fixed-wing builds.
