The FrSky TW R6FB Receiver (FBUS Version) is a compact, lightweight RC receiver designed for pilots seeking reliable dual-band connectivity, ultra-low latency and advanced telemetry. Using FrSky's TWIN TW protocol, it operates across two active 2.4GHz frequency bands simultaneously, providing enhanced signal resilience for demanding RC applications.

Important: The TW R6FB has no PWM servo outputs. Instead, it features seven FBUS channel ports for compatible FBUS equipment and one SBUS output supporting 16-channel and 24-channel modes. This makes it ideal for modern RC setups using compatible FBUS servos, flight controllers and other supported devices.

With 4ms race mode, FBUS/S.Port telemetry, an inverted S.Port connection and Over-The-Air (OTA) firmware updates, the TW R6FB offers advanced functionality in a receiver weighing just 5g.

Product Summary

The FrSky TW R6FB is a dual-band 2.4GHz receiver built for modern RC systems that use FBUS and SBUS connectivity. Its simultaneous active-frequency design, 4ms race mode and telemetry support provide a versatile solution for demanding flying applications.

Unlike conventional receivers with individual PWM servo outputs, the TW R6FB relies on seven FBUS channel ports and one SBUS output. Ensure your servos and connected equipment support the appropriate protocol before purchasing.
