FrSky TW SR12 Receiver - Dual-Band Resilience with Advanced Stabilization and 12 Configurable Channels

Overview

The FrSky TW SR12 is the ultimate receiver for RC enthusiasts who prioritize resilience, long-range performance , and customizable stabilization . Part of the TWIN series , it leverages the TW active-active protocol , simultaneously running on dual 2.4GHz frequency bands . Unlike traditional active-standby redundancy systems, both bands are always operational, ensuring unmatched signal reliability and long-range control.

With 3×2.4G antennas for maximum signal stability and 12 configurable channel ports , the TW SR12 gives you the flexibility to assign ports to PWM, SBUS, FBUS, or S.Port , tailoring the setup to your needs. The FBUS protocol simplifies communication by combining signal control and telemetry into a single connection, cutting down on wiring and streamlining your build.

The ADV Stabilizer feature is a huge upgrade over standard gyroscope stabilization, offering advanced stabilization modes like Auto-Level , Hover , and Knife-Edge . The SR12 also boasts high-precision telemetry sensors for real-time altitude and vertical speed monitoring, further enhancing control and feedback for demanding pilots.

The SR12 is packed with features including Black-Box flight data recording , Over-The-Air (OTA) firmware updates , and a built-in power switch function accessible through optional external switches, all while ensuring safe, reliable power delivery via XT30 connectors  .
