RP3-H ELRS Nano Receiver from RadioMaster - HP0157-0088
The RP3-H ExpressLRS (ELRS) receiver is engineered specifically for the Nexus Helicopter Flybarless control unit and is compatible with all CRSF\/S.BUS-enabled flight controllers. It features a built-in TCXO and a robust integrated housing, making it ideal for installation in modern helicopter frames. This receiver ensures reliable, stable, and precise signal reception, enhancing your flying experience and delivering exceptional performance even in challenging conditions. Additionally, the RP3-H includes an Ext-V telemetry input, allowing compatibility with older ESCs that lack battery voltage telemetry through the control unit.
To boost telemetry performance, the RP3-H employs the Skyworks SKY66112 power amplifier, which provides 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 that deliver outstanding range and low latency. Plus, with built-in WiFi, you can update the firmware directly on your aircraft without needing to remove the receiver.
