FrSky TWIN X14
 
DUAL 2.4G RADIO SYSTEM
The FrSky TWIN X14 stands out as a robust radio system, boasting the capability of utilizing dual 2.4G frequencies simultaneously on the same receiver in TW mode. Different from standard active-standby redundancy solutions, the TW active-active protocol ensures both 2.4G frequency bands are actively engaged on the TWIN series RF module and receiver simultaneously.
 
Equipped with two internal 2.4G RF antennas, the FrSky TWIN X14 offers expansive multi-directional coverage for transmitting signals. Leveraging these attributes alongside the exterior antenna mounting frame, the Twin system provides less latency, higher reliability, and faster data rates with confidence. In addition to the TW mode, FrSky's TWIN X14 also supports ACCST D16 and ACCESS modes, this means users can benefit from a wide range of compatible receiver options to choose from and bind to when building the RC model.
 
ERGONOMIC, COMPACT & FLEXIBLE DESIGN
In alignment with the form factor concept of TANDEM X18, the TWIN X14 has been crafted to enhance its portability, reduce weight, and streamline its design. The ergonomic layout ensures that the momentary buttons, shoulder sliders, and switches on the top are effortlessly accessible.
 
The TWIN X14 offers 4 customizable buttons, thoughtfully placed at the radio panel center for real-time and frequent operations. Take, for instance, when flying an RC glider, to configure these buttons as additional Trim functions by ETHOS, these buttons become invaluable for on-the-fly adjustments then, allowing pilots to adapt the angle of the flaps/surface according to the real-time air environment.
 
BUILT-IN FLASH STORAGE AND RECHARGING SYSTEM | STAND HOLDER ATTACHABLE STRUCTURE DESIGN
Eliminating the need for users to fret over storage decisions, the TWIN X14 boasts built-in 128MB flash storage, providing ample space for your file storage requirements. Its practicality extends to a battery bay accommodating a 2600mAh Li Battery, easily replaceable and featuring a Type-C port for recharging.
Further enhancing its user-friendly design, the TWIN X14 introduces an attachable and foldable structure on the rear shell. This design allows for the easy installation of an additional stand holder accessory, transforming the X14 not only can be conveniently carried but it can also to be positioned anywhere, offering operational flexibility without having to hold the radio in your hands.

Frequently Asked Questions:
Which receivers are compatible with the Twin X14?
The X14 uses the TW (Twin) dual 2.4GHz protocol. Compatible receivers include the TW R10, TWSR8, TW R8, TW R6, and TW MX — all of which run the active-active dual 2.4GHz TW link. The X14 does NOT pair with Tandem (TD) or 900MHz receivers. Browse the full receiver lineup: https://www.fpvbuildsrc.com/frsky-receivers
What is TW (Twin) protocol and how does it work?
TW runs two independent 2.4GHz links simultaneously using active-active diversity — both frequencies are live at all times and the system uses whichever has the cleaner signal moment to moment. This delivers robust 2.4GHz link quality in sport and proximity flying scenarios. It is different from Tandem, which combines 2.4GHz and 900MHz for longer range.
How does the Twin X14 compare to the X14S and X14RS?
The X14 is the standard TW radio without Hall-sensor gimbals. The X14S is the flagship version of the same TW system with precision Hall gimbals added. The X14RS takes the X14 platform and adds a TD-ISRM RS module for an optional 900MHz long-range mode alongside TW. All three run ETHOS OS. Compare: https://www.fpvbuildsrc.com/frsky-transmitters
What firmware/OS does the Twin X14 run?
ETHOS OS — FrSky's color touchscreen operating system with OTA receiver firmware updates, telemetry widget support, and full mixer logic. Free updates via FrSky's firmware site.
Can I use an external module with the Twin X14?
The Twin X14 uses a full-size external module bay (JR format), so you can add ELRS, R9M, or any JR-compatible module if you need to fly other protocols.
Does the Twin X14 support FrID Remote ID for FAA compliance?
Yes — the FrSky FrID module is compatible with the X14 and satisfies FAA broadcast Remote ID requirements: https://www.fpvbuildsrc.com/product-page/frsky-frid-remoteid-module-tailored-for-faa-compliance
