The FrSky Archer Plus R6FB 2.4GHz Receiver is a compact, lightweight receiver designed for RC glider pilots and aircraft builders using FrSky FBUS-compatible equipment. Supporting both ACCESS and ACCST D16 protocols, the R6FB combines enhanced RF interference resistance, flexible telemetry connectivity and support for redundant receiver configurations in a receiver weighing just 4.2g.

Unlike conventional receivers, the Archer Plus R6FB features seven FBUS channel ports and no PWM servo outputs. It is designed specifically for use with compatible FBUS components, such as FrSky XACT servos. Please ensure your servos and other connected equipment support FBUS before purchasing.

Its dual detachable antennas help optimise reception, while SBUS input and output provide additional flexibility for compatible redundant receiver systems and expanded channel configurations. The receiver also supports external battery or device voltage monitoring, basic black-box flight data recording and over-the-air firmware updates, subject to firmware support.

With its compact dimensions and lightweight construction, the Archer Plus R6FB is an excellent option for glider pilots looking to build a streamlined FBUS-based control system with compatible FrSky equipment.

Important compatibility notice: The R6FB does not provide conventional PWM servo outputs. It must be used with FBUS-compatible components. It is not a direct replacement for the standard Archer Plus R6 receiver when PWM servo connections are required.
