RadioMaster ER8G / ER8GV 2.4GHz ExpressLRS PWM 8CH Receiver
Slim, high-performance ELRS receivers for gliders and fixed-wing aircraft – two variants tailored for your needs
The RadioMaster ER8G / ER8GV receivers are designed specifically for gliders and narrow-fuselage aircraft that require a compact 8-channel PWM layout with full telemetry and excellent ExpressLRS link quality. Both variants deliver dual-antenna diversity, automatic voltage detection (receiver or flight battery), support for up to 100 mW telemetry, and fast, low-latency signal response.
The difference between the two models is essential: ER8G is the competition-friendly version without vario, while ER8GV includes a built-in high-precision barometric sensor for detailed climb/sink rate measurement. Choose the version that fits your flying style and competition requirements.
