RadioMaster ER8G & ER8GV ELRS PWM Receiver (2.4ghz)

The RadioMaster ER series PWM receivers, built on the revolutionary ExpressLRS system, offer a top - notch experience for hobbyists. They feature high performance, high reliability, flexible configuration, fast response, and an ultra - long range. The ER8G and ER8GV receivers are tailored for glider pilots, with a compact and slim design. They can control up to 8 servos and come with built - in receiver voltage and flight battery telemetry, which can automatically detect the voltage input. Both models have a dual - antenna setup with a telemetry power of up to 100mw and can work with a 1S Lipo receiver battery. The ER8G is similar to the ER8GV, but without a built - in Vario, suitable for competitions that ban Vario or users who don't need it. **Features**: - Based on ExpressLRS System - High - performance and long - range - Supports 8 PWM Channels - Optimized PCB design - Automatic voltage telemetry - ER8GV has a high - precision air pressure sensor - Wi - Fi updates and WEBUI configuration - 4pin CRSF input port - High - quality 2.54 mm connector - 20 cm High Sensitivity Antenna - Ideal for fixed - wing aircraft and gliders **Specifications**: - **ER8G**: Power supply 3.5 - 8.4V DC, 20cm high - sensitivity antenna, ExpressLRS 3.2 pre - installed, 8CH PWM output, max 100mw return power, battery voltage detection 4.0 - 35V DC, 10.5 grams, 60*13.5*13mm dimensions. - **ER8GV**: Similar to ER8G, plus a built - in high - precision air pressure sensor. **Includes**: 1 x ER8G or ER8GV receiver, 2 x Heat - shrink tubes, 1 x Voltage telemetry wire (Type - A), 1 x CRSF wire, 1 x ELRS - RX - SBUS wire, 1 x User Card.

Using your RadioMaster ER8G or ER8GV receiver is easy. First, connect it to your aircraft's power supply within the 3.5 - 8.4V DC range. Make sure to use the included high - sensitivity 20 cm antenna for the best performance. The receiver can drive up to 8 servos, so connect your servos to the appropriate channels. For battery voltage telemetry, use the provided voltage telemetry wire. The receiver will automatically detect the voltage input. Keep in mind that only one voltage input can be used at a time. When it comes to firmware updates, you can use the Wi - Fi feature and WEBUI configuration. Just follow the instructions on the user card. Here are some important notes: Don't expose the receiver to extreme temperatures or moisture. Avoid physical damage as it may affect the performance. Also, if you're using the ER8G in a competition where Vario is prohibited, it's the perfect choice. For maintenance, keep the receiver clean and free of dust. Check the connectors regularly to ensure a good connection. If you have any issues, refer to the user card or contact the customer support.
