For many ExpressLRS receivers like the RP3-H, you can bind by powering the receiver on and off three times quickly. When the LED double-blinks indicating bind mode, use the [BIND] button in your transmitter's Lua script.
Firmware updates for receivers equipped with WiFi can often be performed wirelessly without removing the unit from your model. Visit the ExpressLRS or RadioMaster website for specific target instructions.
User manuals, firmware updates, and SD card contents can be downloaded directly from the 'Downloads' section of the official RadioMaster RC website.
Most RadioMaster transmitters support a wide range of protocols via the 4-in-1 multi-module or internal ExpressLRS (ELRS), making them compatible with various receiver brands including FrSky, FlySky, and Futaba S-FHSS.
