RadioMaster ER8 2.4GHz ELRS PWM Receiver

The RadioMaster ER8 is an 8-channel ExpressLRS PWM receiver for larger fixed-wing models, multi-servo builds, cars and boats. Dual 20cm antennas, up to 100mW telemetry and automatic voltage reporting give a strong, reliable 2.4GHz link, and the one-piece moulded case is built to last. A spare CRSF port and CRSF/SBUS output let you drive a flight controller too.
