FrSky TD SR18 Tandem Dual-Band Receiver (2.4GHz/900MHz)

Unmatched signal stability, 18 configurable channels, and advanced stabilization—all in one powerful receiver.

Overview
The FrSky TD SR18 Tandem receiver takes signal reliability to new heights, offering simultaneous operation across both 2.4GHz and 900MHz frequencies. With a triple antenna design (2×2.4GHz & 1×900MHz), the TD SR18 ensures wide multi-directional coverage, providing low-latency, long-range control with enhanced anti-interference performance. This receiver is ideal for RC pilots looking for resilience in tough environments and the ability to fly far and wide without losing connection.

The TD SR18 also features a dual-power system via standard XT30 connectors, allowing it to draw power from the source with the higher voltage, ensuring uninterrupted operation during flight. The built-in black box function records essential telemetry data (such as power and signal status), so you can review it later in case of any anomalies.

What truly sets the TD SR18 apart is its 18 configurable channels, each of which can be set to PWM, SBUS, FBUS, or S.Port. Whether you’re pairing with telemetry devices like Neuron ESCs or advanced sensors, this receiver simplifies your build while offering ultimate versatility.

Advanced Stabilizer (ADV) Function
The TD SR18’s ADV Stabilizer takes flight control to the next level, offering more programmable stabilization channels and flexibility than the classic gyroscope stabilization systems. In the classical mode, five additional stabilization channels are available for modes like Stabilization, Auto-Level, Hover, and Knife-Edge, particularly beneficial for fixed-wing aircraft.

In advanced mode, all output pins can be customized for stabilization, and additional features like file sharing, programmable parameters, and developer access offer unmatched control and personalization for your flights. The built-in high-precision telemetry sensors also track critical data like altitude and vertical speed.
