RadioMaster RP3-H ExpressLRS 2.4GHz Receiver (ELRS)

Receiver Overview:

The RP3-H ExpressLRS receiver is engineered specifically for use with our Nexus Helicopter Flybarless control unit and is fully compatible with all CRSF/S.BUS-enabled flight controllers. Featuring a built-in TCXO and an integrated housing design, the receiver is both durable and easy to mount in modern helicopter frames. The RP3-H ensures reliable, stable, and accurate signal reception, enhancing your flight experience and delivering superior performance, even in the most demanding environments. Additionally, the RP3-H includes an Ext-V telemetry input for compatibility with older ESCs that do not provide battery voltage telemetry via the control unit.

Equipped with a Skyworks SKY66112 power amplifier, the RP3-H boosts telemetry performance with up to 100mW of telemetry power and supports antenna diversity through antenna switching. Built around the ESP8285 MCU and SX1281IMLTRT RF Chip, it offers Lora and FLRC 2.4GHz RF links, providing exceptional range and low latency. With built-in Wi-Fi, firmware updates can be done directly on your craft without the need to remove the receiver.
