FrSky Tandem TD SR6 Dual-Band Stabilized 6-Channel Receiver
The Tandem dual-band receivers are unlike any other FrSky 2.4GHz or 900MHz receivers, they work simultaneously at both 2.4GHz and 900MHz frequencies. That means Tandem receivers provide not only the low latency signal and long-range control but also benefit from the enhanced level of high reliability and anti-interference performance.
 
The Tandem series receivers adopt a dual-band antenna design (2.4GHz & 900MHz) that provides multi-directional wide coverage for the remote signal. The telemetry data (Power & Signal related) can be recorded using the built-in black box module within the Tandem receiver, useful for capturing data from any unusual status during the flight.
 
TD SR6 receiver offers 6 PWM channel outputs in a compact lightweight design, with output pins for SBUS Out and FBUS/S.Port. By setting the S.Port to the FBUS protocol, the TD receivers open up seamless pairing with multiple telemetry devices (Neuron ESC, ADV Sensors, etc.) and simplify the build setup.
 
Stabilization Function
The TD SR6 offers an enhanced Stabilization function upgraded over classical gyroscope modes. The advanced mode provides more programmable stabilized channels and flexibility — supporting Stabilization, Auto-Level, Hover, and Knife-Edge flight modes with full pin mapping per channel. Advanced mode adds stab file sharing, programmable parameters, and developer access.

Why We Recommend This
The TD SR6 is the go-to for smaller fixed-wing builds — gliders, trainers, and sport aircraft — where you want Tandem dual-band reliability and built-in stabilization in a compact 6-channel package without the size or weight of a larger receiver. FPV Builds RC provides U.S.-based product support, receiver-selection assistance, and setup guidance for FrSky products purchased through our store.
Frequently Asked Questions:
 
Which FrSky transmitters are compatible with the TD SR6?
The TD SR6 works with all FrSky Tandem series transmitters: X18, X18S, X18SE, X18RS, X20, X20S, X20RS, X20 Pro, X20 Pro AW, and X20 R. Any radio running the Tandem (TD) dual-band protocol or a TD-capable RF module will bind to this receiver. See our full transmitter lineup at https://www.fpvbuildsrc.com/frsky-transmitters
 
What is the difference between the TD SR6 and the TD R6?
Both are compact 6-channel Tandem dual-band receivers with the same RF hardware. The TD SR6 adds a built-in gyro stabilizer — Stabilization, Auto-Level, Hover, and Knife-Edge flight modes. The TD R6 is the non-stabilized version, lighter and simpler, ideal for aircraft with their own flight controller or direct-control setups.
 
What aircraft benefit most from the TD SR6's stabilization?
Fixed-wing aircraft with multiple control surfaces — warbirds, scale planes, gliders, and trainers — benefit the most. The built-in gyro stabilizer reduces pilot workload in turbulence and enables self-leveling recovery from unusual attitudes. It replaces a separate gyro unit, keeping your build clean.
 
What is the Tandem dual-band system?
Tandem receivers operate on 900MHz and 2.4GHz simultaneously — both bands are live at the same time, not failover. 2.4GHz delivers low-latency fast control; 900MHz extends range and cuts through interference. You get the best of both on every flight.
 
How do I use FBUS for telemetry on the TD SR6?
Set the FBUS/S.Port pin to FBUS mode in ETHOS on your Tandem transmitter. Connect ADV sensors (FAS, GPS, VARI) or a Neuron ESC. Bidirectional data flows on a single wire — sensor readings appear live on your radio screen with no hub required. Browse compatible sensors at https://www.fpvbuildsrc.com/frsky-sensors
 
Does the TD SR6 support OTA firmware updates?
Yes. Firmware updates are delivered over-the-air from your Tandem transmitter via ETHOS — no USB or computer required.
 
How do I configure the TD SR6's stabilization in ETHOS?
Current FrSky stabilized receivers are configured through the applicable Stabilizer Config/device configuration functions in ETHOS. Receiver orientation, aircraft type, stabilization mode, channel assignments, and related settings should be configured for the specific receiver and aircraft installation. Follow the current FrSky/ETHOS instructions for the TD SR6.
Does FPV Builds RC offer setup support for the TD SR6?
Yes — we're a U.S.-based FrSky dealer happy to help with binding, stabilization tuning, and FBUS wiring. Browse our full FrSky receiver range at https://www.fpvbuildsrc.com/frsky-receivers
