HD Digital Video Transmission System
FrSky Tandem X20 series HD radio system provides the perfect solution for FPV flying and pilots preferring an easier operation with fewer devices. The HD version of the X20 radio system includes an integrated FPV screen supporting 720p 60FPS video quality, removing the need for a standalone FPV screen. When combining the HD 720p 60FPS video with near 0ms low latency digital video transmission technology, the X20 HD radio will provide more enjoyment and confidence when FPV flying tours. The built-in video receiver module is compatible with all HDZero video transceiver (VTX) products.

The X20 HD radio package includes a 5.8G antenna kit. The circularly polarized directional antennas ensure that the radio receives optimum video transmission signals, even in complex RF environments. The HD version of the X20 radio also provides an HDMI output which can be used to easily transfer the HD video to an external monitor or device if required, this provides a great solution if you wish to use your existing FPV goggles which support HDMI-in, removing the need for separate HDZero video receiver attached to your goggles.

Tandem X20 Series:
The FrSky Tandem X20 Series is a dual-band telemetry radio system, its development has drawn on valuable feedback from FrSky’s extensive customer base, experience with previous radios and introduces many new features such as a color touch screen display, underpinned by an ergonomic design that provides unprecedented comfort when held. On the RF side, FrSky has introduced a powerful and reliable TD dual-band RF system, which features the advantages of the FrSky 868MHz and 2.4GHz in one combined RF system. The TD dual-band RF system is characterized by true simultaneous dual-band remote control with telemetry, and superb end-to-end 4ms latency performance. When combined with ETHOS, a completely new operating system, FrSky’s Tandem X20 Series provides users with a powerful, intuitive, and flexible experience to enjoy across the entire world of RC.

A Very Well Thought Through Radio Design
Tandem X20 Series design has focused highly on technology, ergonomics, and user experience as follows:

Hardware Design
The overall weight of Tandem X20 Series has been kept low, less than 1000 grams, by incorporating the use of light-weight materials while maintaining a strong and robust quality. The radio system comes with an 800 x 480-pixel color touch screen display on the top area of the radio which is easy to read indoors and in direct sunlight outdoors.

The Tandem X20 Series has been complemented with 6 customizable buttons on the front case that allows for quick switching between features, ideal to be used for flight modes. Additional 2 rear momentary buttons have been introduced to provide flexibility, in the ideal position for DLG pilots launch fingers no matter if you are left or right-handed. All the trims and pots adopt the CNC metal hardware that makes the radio more endurable.

Ergonomics
The two side handle grips of Tandem X20 Series are made with a high-quality comfortable material, designed ergonomically to fit the hand very well. Both hall-gimbals are well-positioned which makes the sticks very close to the grip edge allowing for ease to reach and control, also the spring tension can be adjusted.

Internal 868MHz/2.4GHz Dual-Band & External Module Bay
The TD dual-band RF system combines both the features and advantages of FrSky 868MHz and 2.4GHz RF together in one system. The TD features real simultaneous dual-band long-range control with telemetry that achieves reliable end-to-end 4ms latency while maintaining a robust and high-quality signal link. The entire range of TD, ACCESS & ACCST D16 receivers are supported. The built-in TANDEM RF System supports ACCESS and ACCST D16 protocols.
In addition, the Tandem X20 Series includes a rear Lite version module bay to offer more options to connect external devices. The external Lite module bay supports R9M Lite, R9M PRO Lite, XJT Lite, etc. FrSky welcomes working compatibility with the 3rd party products with their own developed technology following FrSky verified 3rd party compatibility-testing program.
