FrSky's 4 channel ACCESS receiver.

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!

High Performance

This has become my favorite receiver. I couple it with an Aura stabilizer board, and an M+ redundant receiver- usually in the tail. I have not had a situation where rssi was dangerously low, or compromised telemetry. I'm using an X10 Express on Open TX and an X20 on Ethos. Both configurations have been flawless . I will buy a few more.

Good receiver, but a cold-solder joint surprised me.

Found that one of the pins in the receiver had a cold solder joint - easily fixed - but surprising due to the high quality of the FrSky receivers in general.
