FrSky Tandem X20 Pro
 
TD-ISRM PRO RF PERFORMANCE
With solid performance based on the dual-band 900M/2.4G RF signal link with multiple operating combinations of RF modes, the TANDEM PRO delivers proven dual-band RF performance. The X20 PRO added the dual 2.4G TW RF mode and supports simultaneous activation of both TW and ACCESS R9 modes. In this configuration, TW receiver and ACCESS R9 receiver can be connected via the SBUS IN/OUT ports to achieve redundant backup. This RF signal connection method allows for the simultaneous use of three different RF links in RC applications. This further enhances the RF signal’s reliability, particularly in scenarios involving long-distance RC operations.
 
COMPREHENSIVE FUNCTIONAL INPUTS & SOLID-QUALITY METAL PARTS
The X20 PRO optimizes and integrates the functional inputs of the TANDEM series models. Building on the foundation of X20/X20S, it adds 2 extra trims, allowing for more precise tunings during the operations. The levers on both sides of the transmitter’s slider support customizable positioning of the center toward, catering to different users’ habits and preferences. Additionally, at the index finger position on the left and right sides of the handle top of the X20 PRO, one self-locking button is set on each side for users to flexibly do application settings for various scenarios.
The main body of the X20 PRO is constructed with a all CNC-machined metal material, and the central panel incorporates genuine carbon fiber material. The primary input components, including trim caps, slider levers, and knobs, are all made from metal, offering rugged quality and enhanced durability for outdoor use.
 
BUILT-IN MASS STORAGE & TEXT TO SPEECH FUNCTION
In order to save the user the trouble of deciding the storage capacity, X20 PRO comes with a built-in 8GB flash storage that offers plenty of file storage to meet all of your radio’s storage needs, along with high data transmission speed.
Thanks to the upgraded storage feature, the TTS (Text-to-Speech) function of X20 PRO can quickly and conveniently convert typed input English words into spoken speech. This enables the ETHOS system to more flexibly match the triggered operational status using generated speech file when specific functions are activated, and to alert clearly outdoors with the digital power amplifier module.

Why We Recommend This
The X20 Pro is the versatile Tandem flagship — the same dual-band system as the X20 Pro AW but in a more accessible package, with the option to add the TDSR18 or other TD receivers as a combo. Our recommendation for pilots who want a full X20-class experience with flexibility on the receiver side. FPV Builds RC provides U.S.-based product support, transmitter-setup assistance, and configuration guidance for FrSky radios purchased through our store.
Frequently Asked Questions:
Which receivers are compatible with the Tandem X20 Pro?
The X20 Pro works with all three FrSky receiver families: Tandem (TD) dual-band receivers (TDR10, TDR12, TD SR10, TD SR12, TD SR18) for the best range and redundancy on 2.4GHz + 900MHz simultaneously; ACCESS receivers (Archer Plus series); and ACCST D16 receivers for legacy compatibility (older units may need a firmware update). Browse all compatible receivers at https://www.fpvbuildsrc.com/frsky-receivers
How does the X20 Pro compare to the X20S, X20RS, and X20 Pro AW?
The X20 Pro is the mid-tier Tandem radio without Hall-sensor gimbals (the X20S and X20RS have Hall gimbals). The X20RS adds a TD-ISRM RS module for 900MHz long-range mode. The X20 Pro AW (Aero Wing Edition) is a specialized variant with extended battery life and a larger form factor designed for fixed-wing and glider pilots. The base X20 Pro is the right choice for pilots who want the Tandem dual-band system at a more accessible price point. See the full family: https://www.fpvbuildsrc.com/frsky-transmitters
What firmware/OS does the X20 Pro run?
ETHOS OS — FrSky's color touchscreen operating system. ETHOS supports OTA firmware updates for bound TD receivers, telemetry widgets, and flexible mixer logic. Regular free updates are available from FrSky's firmware site.
Does the X20 Pro have an external module bay?
Yes — a full-size JR-compatible external module bay. You can fly ELRS, R9M, or any other JR-format RF module alongside the built-in Tandem system, which is ideal when flying legacy aircraft on other protocols.
What case or tray accessories work with the X20 Pro?
The X20 Pro Aluminum Box is designed specifically for this radio: https://www.fpvbuildsrc.com/product-page/frsky-x20-pro-aluminum-box. The CNC Metal Tray at https://www.fpvbuildsrc.com/product-page/frsky-cnc-metal-tray-for-tandem-x20-x20s-x18-series and Shoulder Strap at https://www.fpvbuildsrc.com/product-page/frsky-transmitter-shoulder-strap are also compatible. Note: the aluminum box fits the standard X20 Pro, not the X20 Pro AW.
Does the X20 Pro support FrID Remote ID for FAA compliance?
Yes. The FrSky FrID Remote ID module is compatible with the X20 Pro and satisfies FAA broadcast Remote ID requirements. See it here: https://www.fpvbuildsrc.com/product-page/frsky-frid-remoteid-module-tailored-for-faa-compliance
