Product name:Radiomaster ER8-G/ER8-GV 2.4GHz 8CH ExpressLRS ELRS RX 100mW PWM Receiver Support Voltage Telemetry for FPV RC Drone Airplane Glider Precise details: The RadioMaster ER series of PWM receivers are based on the revolutionary ExpressLRS system. It offers high performance, high reliability, flexible configuration, quick response speed and ultra-long range bringing you brand new experience with your hobby. The ER8G & ER8GV receiver have been specially designed for glider 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.
