Description

The RadioMaster ER8G leverages the ExpressLRS open-source protocol to provide a high-performance, long-range control link optimized for fixed-wing aircraft and gliders. Its design prioritizes a minimal footprint and weight while maintaining full telemetry and configuration capabilities.

Engineered for reliability, the receiver features an optimized PCB layout and high-quality 2.54mm connectors. It supports telemetry power output adjustable up to 100mW via LUA scripts, allowing pilots to balance range against power consumption based on their specific flight profile and environment.

Key Features

  • Based on the open-source ExpressLRS 2.4GHz system for low-latency, long-range control.
  • Dedicated 8-channel PWM output for direct connection to servos and other actuators.
  • Automatic detection and telemetry for receiver voltage (3.5-8.4V) or external battery voltage (4-35V).
  • Integrated Wi-Fi hotspot enables firmware updates and receiver configuration via a standard web browser.
  • Reserved 4-pin CRSF input port for future expansion or alternative control methods.
  • High-sensitivity dual-antenna design with 20cm leads for optimal signal diversity and reception.
  • Compact form factor (60mm x 13.5mm) and lightweight construction (12g) for minimal airframe impact.
  • Compatible with all 2.4GHz ExpressLRS transmitters and external modules.

Applications

  • Fixed-wing RC aircraft requiring reliable, long-range control with servo PWM outputs.
  • Competition and recreational gliders where minimal weight and compact size are critical.
  • Scale model builds needing integrated voltage telemetry for flight pack monitoring.
  • Any RC model compatible with ExpressLRS 2.4GHz where direct PWM servo control is preferred over serial protocols.

Frequently Asked Questions

What is the main difference between the RadioMaster ER8G and the ER8GV receiver?

The ER8G and ER8GV share identical core functionality, including 8 PWM channels, voltage telemetry, and Wi-Fi configuration. The key difference is that the ER8GV includes a built-in high-precision barometric pressure sensor (Vario) for altitude telemetry, while the ER8G omits this sensor for applications where a vario is prohibited or not required.

How do I update the firmware or configure the ER8G receiver?

The ER8G features an integrated Wi-Fi access point. Power the receiver, connect to its Wi-Fi network from a computer or smartphone, and access its built-in WEBUI via a browser. This interface allows for firmware updates and configuration of parameters like telemetry power and binding phrases without needing a transmitter.

What voltage inputs can the ER8G receiver monitor and report via telemetry?

The ER8G can automatically detect and report telemetry for one voltage source at a time. It monitors its own receiver bus voltage (3.5-8.4V) when powered directly. If connected via the included voltage telemetry wire, it can also monitor an external flight battery voltage within a range of 4.0V to 35V, suitable for most LiPo and Li-ion packs.

Is the RadioMaster ER8G compatible with my existing ExpressLRS transmitter?

Yes, the ER8G is compatible with all 2.4GHz ExpressLRS systems. This includes transmitters with internal ExpressLRS modules (like the RadioMaster Boxer or TX16S) and those using external 2.4GHz ExpressLRS modules via a JR bay or serial connection, provided they are running compatible firmware versions.
