Radiomaster RP3-H ExpressLRS 2.4GHz Nano Receiver

The RadioMaster RP3-H ExpressLRS 2.4GHz Nano Receiver is designed specifically for use with the Nexus helicopter flybarless system control unit. It is also compatible with all flight controllers that support CRSF/S.BUS protocols. This receiver features a built-in TCXO (temperature compensated crystal oscillator) for stable and accurate performance, and an integrated housing design that makes it reliable and easy to install.
