FrSky's 4 channel ACCESS receiver.

Availability: Out of stock

  • Don't let the tiny package fool you, this is a serious receiver with more of everything you love about FrSky!

    The FrSky Archer R4 receiver is perfect for all types and sizes of models requiring 4 channels or less. As it utilizes the new and exciting ACCESS protocol, you can expect Over The Air firmware updates (OTA), increased range and telemetry performance as well as configurable S.Port/F.Port and telemetry output power. You can also use the R4 as a redundant receiver via the SBUS input when paired with another SBUS capable receiver.

    The radio will need to be running the most recent IXJT v2.1.x firmware to use Archer receivers!
