Meet the Radiomaster RP3-H ELRS 2.4GHz Nano Receiver, the unsung hero of your helicopter's flight experience. Specifically engineered for the Nexus Helicopter Flybarless control unit and compatible with CRSF/S.BUS enabled flight controllers, this receiver isn't just another piece of hardware. Featuring a built-in TCXO and a robust housing design, the RP3-H is ready to endure the toughest of aerial maneuvers. Enjoy unmatched signal stability and performance, even in the most challenging environments. With an Ext-V telemetry input, it's also backward compatible with older ESCs lacking battery voltage telemetry.

Equipped with the Skyworks SKY66112 power amplifier, this receiver boosts telemetry performance to new heights with up to 100mW of power. Developed around the ESP8285 MCU and SX1281IMLTRT RF Chip, it offers superior Lora and FLRC 2.4GHz RF links, delivering incredible range and low latency. Plus, the built-in WiFi makes firmware updates a breeze—no disassembly required.
