Expertly designed for ultimate performance, the FrSky Tandem X20R Dual Band Ethos Radio is a premium choice for reliable and long-range communication with your model. With a focus on quality and comfort, this radio is incredibly easy to use, making it the perfect option for all your needs. Trust in its dual-band capabilities for a seamless experience.


With solid performance based on the dual-band 900M/2.4G RF signal link with multiple operating combinations of RF modes, the TANDEM X20R & X20RS versions are equipped with the TD-ISRM Pro built-in RF module which is capable of supporting multiple protocols (like TW, TD, etc), with same RF capability as X20 Pro editions.

The TD-ISRM Pro RF module has the dual 2.4G TW RF mode and supports simultaneous activation of working under TW and ACCESS R9 modes with the same module. In this configuration, the TW receiver and ACCESS R9 receiver can be connected via the SBUS IN/OUT ports to achieve redundant backup. This RF signal connection solution makes use of three different RF links at the same time in RC applications. This further enhances the RF signal’s reliability, particularly in long-distance RC operations scenarios.


The X20R and X20RS have changed from the original X20 design in appearance. The bottom hand grip adopts the overall design of the PRO version, eliminating the need for an additional grip cover, and allowing the bottom part to be fully grasped by the palm for a more comfortable and relaxed grip. Additionally, the Lite-type external module slot has been adjusted to provide more fitting installation space for external modules of different shapes, making it more convenient.

R and RS versions add 2 extra trims, allowing for more precise tunings during the operations. The slider levers on both sides of the transmitter support adjusting the positioning of the center, catering to different users’ habits and preferences. The primary input components, including trim caps, center-slider caps, and knobs are all made from metal, offering rugged quality and enhanced durability for outdoor use.


The newly upgraded antenna handle incorporates the good capability of impact resistance facing the tough conditions of outdoor fields. The reinforced and thickened antenna casing is better suited for comfort gripping but also does not compromise the antenna’s performance. On the contrary, the redesigned antenna can transmit signal data more effectively, providing pilots with a more reliable flying control experience.

The X20R & X20RS are also equipped with 2 external antenna connectors, which can be mounted with additional 2.4G and 900M antennas for enhancing the RF capabilities working under the LoRa modes, to achieve enhanced long-range control.
