The RadioMaster ER series of PWM receivers is built on the innovative ExpressLRS protocol. It provides high performance, dependable signal, versatile configuration, and quick response time, offering a new experience for your projects and applications.

The ER8G & ER8GV receiver have been specially designed for pilots who require a compact and slim receiver. It can drive up to 8 servos and has built-in receiver voltage telemetry and flight battery telemetry with the ability to automatically detect which voltage input to use (only one voltage input can be used at the any given time). Both ER8G & ER8GV feature a dual-antenna with telemetry power up to 100mw and can be used with a 1S Lipo receiver battery.

The ER8G Receiver has the same functionality as the ER8GV only without a built in Vario for competitions that prohibit the use of Vario or simply for users who do not need a vario on their receiver.
