The FrSky TWIN TW SR12 Stabilised Receiver is an advanced RC receiver combining FrSky's dual active 2.4GHz TWIN protocol with an integrated ADV stabilisation system, comprehensive telemetry and 12 configurable channel ports. Designed for demanding RC aircraft applications, the TW SR12 delivers flexible control options, enhanced signal resilience and sophisticated flight stabilisation features.

Unlike conventional receivers that rely on fixed output configurations, the TW SR12 allows each channel port to be assigned as PWM, SBUS, FBUS or S.Port. This flexibility simplifies installation and supports modern RC systems, including compatible XACT servos and ADV sensors. FBUS connectivity can combine control signals and telemetry over a single connection, helping reduce wiring complexity.

The integrated ADV Stabiliser takes flight assistance beyond conventional gyro stabilisation. It supports multiple flight modes, including Stabilisation, Auto-Level, Hover and Knife-Edge for suitable aircraft configurations. Advanced mode provides additional programmable stabilisation channels, configurable output pins, stabilisation file sharing and adjustable parameters.

With three 2.4GHz antennas, dual XT30 power inputs, a built-in power switch function and high-precision telemetry sensors, the TW SR12 is a powerful solution for pilots seeking advanced control, stabilisation and monitoring capabilities.
