❓ Frequently Asked Questions
How many servos can the ER6 control?
It provides six PWM channels and can directly control up to six compatible PWM devices, subject to the model’s power-system capacity.
Does it work with an ELRS 900MHz transmitter?
No. This receiver operates on 2.4GHz and requires a compatible 2.4GHz ExpressLRS transmitter or module.
Does the ER6 include a variometer?
No. The standard ER6 does not contain a barometric variometer. RadioMaster offers other ER-series models for applications requiring a built-in vario.
Can it measure the flight battery voltage?
Yes. The included Type-B telemetry wire can measure an external battery voltage from 4.0V to 35V when connected correctly.
Can the receiver be powered from a 6S battery?
No. Its normal power input accepts 4.5–8.4V. A suitable regulated BEC is required when the model uses a higher-voltage flight battery.
Does it support CRSF and SBUS?
Yes. In addition to its six PWM channels, the ER6 supports CRSF and SBUS serial outputs.
Can its firmware be updated wirelessly?
Yes. The ER6 supports ExpressLRS Wi-Fi firmware updates and WebUI configuration.
Is it compatible with every RadioMaster transmitter?
It works with RadioMaster transmitters that have an internal 2.4GHz ExpressLRS module or a compatible external 2.4GHz ELRS module. Multi-protocol-only transmitters require a separate ELRS module.
