The FrSky Archer Plus R6FB is an advanced 2.4GHz receiver designed for RC gliders and aircraft using modern FBUS-compatible digital components. Featuring seven FBUS channels, dual detachable antennas, telemetry support and enhanced resistance to RF interference, it provides a streamlined solution for pilots seeking reliable signal performance and simplified electronic installations.

Unlike conventional receivers, the Archer Plus R6FB has no PWM servo outputs. It is designed to work with FBUS-compatible equipment, such as FrSky XACT digital servos. Before purchasing, ensure your transmitter and connected components support the required FrSky protocols and FBUS connectivity.

Compatible with FrSky ACCESS and ACCST D16 transmitters, the R6FB intelligently matches the supported RF protocol during binding. It also supports SBUS input for receiver redundancy, SBUS output in 16-channel or 24-channel mode, OTA firmware updates and telemetry through S.Port or FBUS.
