FrSky Tandem TD R6 2.4GHz + 900MHz Dual-Band 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 R6 receiver offers 6 PWM channel outputs and is bundled in a compact lightweight design, the receiver also provides two 3-pin ports accordingly for SBUS Out and FBUS/S.Port. By setting the S.Port to the FBUS protocol, the TD receivers can open up the possibility of seamlessly pairing with multiple telemetry devices (Neuron ESC, Advance Sensors, etc.) as well as simplifying the build setup.

Why We Recommend This
The TD R6 is the minimalist entry point to the Tandem dual-band system — 6 channels, compact size, and full simultaneous 900MHz/2.4GHz coverage. Perfect for sport aircraft, EDF jets, and builds where you don't need high channel counts but still want Tandem range. 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 R6?
The TD R6 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 R6 and the TD SR6?
Both are compact 6-channel Tandem dual-band receivers with the same RF hardware. The TD SR6 adds a built-in gyro stabilizer for self-leveling flight modes — Stabilization, Auto-Level, Hover, and Knife-Edge. The TD R6 is the non-stabilized version — lighter and ideal for aircraft with their own flight controller or for direct-control setups.
 
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 punches through interference for remarkable long-distance reliability.
 
Does 900MHz activate automatically?
Yes. Your Tandem transmitter activates the 900MHz link automatically when bound to a TD receiver — no extra steps in ETHOS required. Both frequencies are live from the first bind.
 
How do I use FBUS for telemetry on the TD R6?
The TD R6 has a dedicated FBUS/S.Port port. Set it to FBUS mode in your transmitter's ETHOS receiver settings, then 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.
 
Does the TD R6 support OTA firmware updates?
Yes. Firmware updates are delivered over-the-air from your Tandem transmitter via ETHOS — no USB cable or computer required.
 
Does FPV Builds RC offer setup support for the TD R6?
Yes — we're a U.S.-based FrSky dealer happy to help with binding and FBUS setup. Browse our full FrSky receiver range at https://www.fpvbuildsrc.com/frsky-receivers
