The RadioMaster ER Series PWM receivers are built around the innovative ExpressLRS protocol, delivering high performance, reliable signal transmission, flexible configuration, and fast response times for a wide range of R/C applications.

Designed for pilots who require a compact and slim receiver, the ER Series can drive up to 8 servos and features built-in receiver voltage telemetry and flight battery voltage telemetry, with automatic detection of the appropriate voltage input. Only one voltage input can be used at a time.

Both the ER8GV and ER8G feature a dual-antenna design and support up to 100mW telemetry power, while also supporting operation with a 1S LiPo receiver battery.

The ER8G offers the same core functionality as the ER8GV, but without the built-in vario, making it ideal for competitions where vario sensors are prohibited or for pilots who simply do not require vario functionality.
