FrSky TWIN X14RS
TD-ISRM RS RF PERFORMANCE
With solid performance based on the dual-band 900M/2.4G RF signal link with multiple operating combinations of RF modes, the FrSky X14RS model is equipped with the TD-ISRM RS built-in RF module, which is capable of supporting multiple protocols (like TW, TD, etc).

The TD-ISRM RS RF module has the dual 2.4G TW RF mode and supports simultaneous activation of working under ACCESS 2.4G and R9 modes with the same module. In this configuration, the ACCESS 2.4G receiver and R9 receiver can be connected via the SBUS IN/OUT ports to achieve redundant backup. This further enhances the RF signal’s reliability, particularly in long-distance RC operations scenarios.
ERGONOMIC, COMPACT & FLEXIBLE DESIGN | MC18 GIMBALS WITH SPIKED ANTI-SLIP STICKENDS

In alignment with the form factor concept of X18 series radios, the X14 series 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 X14RS 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. Apart from the X14/X14S models, the X14RS features a 3-inch 640×360 resolution display with touchscreen capability, delivering a smoother and more convenient user experience.

The X14RS is equipped with all CNC-machined metal MC18 hall gimbals, with a default travel angle of 60°. By using the limiter accessory tool, the Y-axis travel can be adjusted to a shorter 45° range. Additionally, paired with the 360° all-arounded spiked anti-slip stickends, it ensures precise and confident control even in the most intense and exciting racing moments.
BUILT-IN FLASH STORAGE AND RECHARGING SYSTEM | STAND HOLDER ATTACHABLE STRUCTURE DESIGN

Eliminating the need for users to fret over storage decisions, the X14RS boasts built-in 512MB 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 X14RS 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 X14RS 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.

Why We Recommend This
The X14RS brings the TD-ISRM RS module to a full-size Twin-style radio — you get the extended 900MHz RS range of the Tandem system in a lighter, more budget-friendly package than the X20 series. Our choice for pilots who want long-range dual-band coverage without the X20 price point. 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 X14RS?
The X14RS features both the TW dual 2.4GHz module AND the TD-ISRM RS module, giving you two protocol options. For TW mode, use TW receivers (TW R10, TWSR8, TW R8, TW R6, TW MX). For Tandem/RS mode, use TD dual-band receivers (TDR10, TDR12, TD SR12, TD SR18) or ACCESS/ACCST receivers. See the full lineup: https://www.fpvbuildsrc.com/frsky-receivers
What makes the X14RS unique — what is the RS module?
The X14RS is the only radio in the X14 family to combine the TW active-active dual 2.4GHz system with the TD-ISRM RS module, which adds a dedicated 900MHz long-range mode. This hybrid design means you can fly TW proximity missions and switch to 900MHz RS range for long-range fixed-wing — all in one radio.
How does the X14RS compare to the X14S and X14?
The X14S is the flagship TW radio with Hall gimbals but no 900MHz capability. The X14 is the standard TW model without Hall gimbals or RS. The X14RS adds the TD-ISRM RS 900MHz module on top of the X14-class TW system, making it the most versatile radio in the family. Compare: https://www.fpvbuildsrc.com/frsky-transmitters
