FrSky Twin TW R8 Receiver

FrSky TWIN TW R8 Receiver

The FrSky TW R8 brings FrSky’s advanced TWIN protocol into a compact, lightweight 8-channel receiver designed for pilots who want strong 2.4GHz reliability, flexible wiring options, and clean receiver integration. Unlike traditional single-band 2.4GHz receivers, the TW R8 uses FrSky’s dual active 2.4GHz system, allowing both 2.4GHz frequency bands to operate at the same time for improved signal stability and redundancy.

This active-active design is different from basic backup receiver systems, where one signal path only takes over after the other has failed. With the TW R8, both 2.4GHz links are working simultaneously, helping provide a more stable and dependable connection throughout the flight. The receiver is equipped with dual 2.4GHz antennas for strong signal coverage and long-range control performance.

The TW R8 includes 8 PWM output channels, SBUS Out, SBUS In for signal redundancy, and FBUS/S.Port telemetry support. When configured for FBUS in ETHOS, signal control and telemetry can be handled through a single wire with compatible FBUS devices, helping simplify wiring and create a cleaner aircraft setup.

Compatibility Note

The TW R8 is compatible with FrSky TWIN Series radios and RF modules operating in TW mode. This includes the FrSky TWIN X14, TWIN X14S, and other TWIN Series transmitters that support TW protocol. It is not a Tandem TD receiver and should be used with TWIN/TW-compatible systems.
