The FrSky TD SR12 Tandem Receiver is a high-performance dual-band receiver designed for advanced RC pilots who demand maximum reliability, flexibility, and control. Operating simultaneously on both 2.4GHz and 900MHz frequencies, the TD (Tandem) system delivers ultra-low latency alongside exceptional long-range capability and industry-leading resistance to interference.

Equipped with a triple antenna system (2× 2.4GHz and 1× 900MHz), the TD SR12 ensures wide, multi-directional signal coverage for robust connectivity in all flight conditions. Its dual power input system, using XT30 connectors, provides safe and efficient power delivery with automatic load balancing between power sources—ideal for high-value or large-scale models.

The receiver features 12 fully configurable channel ports, allowing each to be assigned as PWM, SBUS, FBUS, or S.Port. This flexibility, combined with FBUS capability, enables simplified wiring and seamless integration with advanced telemetry devices such as ESCs and sensors.

A standout feature is the integrated ADV Stabiliser system, offering significantly enhanced control compared to traditional gyro stabilisation. With programmable stabilised channels, multiple flight modes (including Auto-Level, Hover, and Knife-Edge), and advanced configuration options, it delivers precision and adaptability for complex aircraft setups.

Built-in telemetry sensors provide real-time data such as altitude and vertical speed, while the integrated black box records critical flight data for post-flight analysis and improved safety.
