The Tandem (TD) dual-band receivers are unlike any other FrSky 2.4Ghz or 900Mhz receivers, they work simultaneously at both 900Mhz and 2.4Ghz frequencies. That means TD receivers provide not only low latency signal and long-range control but also benefit from the enhanced level of high reliability and anti-interference performance.

The TD SR12 receiver is equipped with a triple antenna (2×2.4G & 1×900M) design that provides multi-directional wide coverage for the remote signal and is designed for RC users who want to benefit from resilience and long-range in their radio communications.

TD SR12 also provides a socket that can be used to connect the NFC Switch panel to enable the built-in Power Switch function. Dual-power provides a safe and efficient way to power the system with your power sources connected via a pair of standard XT30 connections. The dual-power consumption system is designed to operate in balance mode, where it consumes the power line from either power source depending on which has the higher voltage. With a built-in black box module, the data (Power & Signal related) under unusual status during the flight can be recorded by TD receivers.

The configurable 12-channel ports are a big feature of TD SR12, each channel port can be assigned as PWM, SBUS, FBUS, or S.Port. With the FBUS protocol, the Tandem series receivers can open up the possibility of seamlessly pairing with multiple telemetry devices (Neuron ESC, Advance Sensors, etc.) as well as simplifying the builds setup.

ADV Stabilizer
The TD SR12 offers an ADV Stabilizer function which is an upgrade over the original classical gyroscope stabilization modes. The ADV Stabilizer offers an advanced mode that provides more programmable stabilized channels and flexibility.

The classical stabilization mode has been enhanced with 5 additional stabilization channels, providing pin mapping to each channel in the multiple flight modes like Stabilization, Auto-Level, Hover, and Knife-Edge with an airplane model.

In the advanced stabilization mode, all the output pins are configurable for stabilization and additional advanced features such as Stab file sharing, programmable parameters, developer access, etc.

The advanced stabilizer feature incorporates high-precision telemetry sensors to monitor altitude, vertical speed, etc. This ADV feature is an additional benefit compared to using a regular S series stabilization receiver.
