RadioMaster ER8GV 2.4GHz ELRS 8CH PWM Receiver with Vario

The RadioMaster ER8GV is a 2.4GHz ExpressLRS PWM receiver with eight servo outputs and a built-in barometric vario, aimed at glider and fixed-wing pilots who want climb-rate and altitude telemetry on the radio. It works with every 2.4GHz ELRS transmitter and module and can run from a 1S LiPo receiver pack.

Key features

• Eight PWM channels on 2.54 mm headers, plus a reserved 4-pin CRSF port and CRSF/SBUS serial output for a flight controller or stabiliser

• High-precision air-pressure sensor sends vario and altitude data to the radio

• Dual-antenna diversity receiver with a standard 20 cm high-sensitivity antenna

• Automatic voltage telemetry from either the receiver supply or an external flight pack, sensing 4.0–35 V; one input is read at a time

• Telemetry output up to 100 mW, set from the radio's Lua script

• Wi-Fi firmware updates and WebUI configuration

If your competition rules ban a vario, the ER8G is the same receiver without the pressure sensor. Match the ELRS major version and binding phrase to your transmitter before the first flight.
