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 has been kept low, less than 1000 grams, by incorporating the use of lightweight 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 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 the 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 easy to reach and control, also the spring tension can be adjusted. Furthermore, S & HD versions of the X20 support adjustable rotation angle on its gimbals, so you can set them in the orientation you find most comfortable.

Internal 900MHz/2.4GHz Dual-Band & External Module Bay

The TD dual-band RF system combines both the features and advantages of FrSky 868/900MHz 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 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.
