More info

The Archer R4 has 4 high-precision PWM channel outputs bundled in a compact light-weight design. It supports full-range signal strength with dual detachable antennas to assure optimal antenna reception and maximum range. In addition to all this, the R4 can also be used as a redundancy receiver along with any other FrSky ACCESS capable receiver equipped with a SBUS port. The best available signal will be used to ensure superior connectivity.


All of the Archer receivers are hyper-matched with the ACCESS protocol. They not only feature wireless firmware upgrades, increased range, and telemetry performance, the R4 now supports more functions like configurable telemetry power, S.Port/F.Port switching and FLR output. Additional valuable features are under development to unlock the true potential of the ACCESS protocol.
