The RadioMaster RP series receivers are built-in a TCXO (temperature-compensated crystal oscillator) now, which ensures reliable, stable, and accurate signal reception, allowing for superior performance in demanding environments and enhancing the flight experience.

The RadioMaster RP series of receivers are designed with size, ease of use and range in mind. Utilizing ExpressLRS 2.4ghz Open-source firmware the RP series of nano receivers deliver features and range today’s pilots have come to expect.

Developed around the ESP8285 MCU and SX1280IMLTRT RF Chip the RP series offer Lora and FLRC 2.4ghz RF links offering incredible range and low latency. With Wifi built-in FW updates can be done on your craft without the need to remove the receiver. Binding can be done using a bind phrase meaning no more bind plugs or fiddly button presses while trying to plug in your battery.

The RP3 receiver features a Skyworks SE2431L providing an LNA for improved receiver performance, a PA providing up to 100mW of telemetry performance and antenna switching for antenna diversity.
