The FrSky Twin TW SR8 is a high-performance dual 2.4GHz receiver designed for FrSky TWIN-series radio systems and RF modules operating in TW mode. Its simultaneous active-active dual-frequency architecture provides a stable control link, while the built-in ADV Stabilizer and high-precision telemetry sensors add advanced capabilities for demanding RC aircraft applications.

With 8 PWM output channels, SBUS In/Out, FBUS and S.Port support, the TW SR8 offers flexible connectivity and simplified model wiring. Its ADV Stabilizer provides enhanced programmable stabilisation, multiple flight modes and configurable output pins, making it particularly well suited to aerobatic, scale and other fixed-wing models where precise control and telemetry are important.
