FrSky TW SR12 Receiver

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.
