Using the RadioMaster ER6 ELRS PWM Receiver is straightforward. First, connect it to your fixed-wing aircraft according to the wiring instructions in the user card. Make sure to use the high - quality 2.54 mm connector properly. The receiver will automatically detect the voltage input for telemetry. You can support up to 6 servos, which gives you great flexibility in your aircraft setup. For updates and configuration, you can use Wi - Fi and the WEBUI. When it comes to maintenance, keep the receiver clean and dry. Avoid exposing it to extreme temperatures or moisture. The standard 20 cm high - sensitivity antenna should be handled carefully to prevent damage. If you want to expand the telemetry functions, use the reserved 4 - pin CRSF input port. And don't forget to check the voltage telemetry regularly to ensure the battery and receiver are working properly.
