Tandem X20 Series of radio control systems from FrSky is one of the few radios available that incorporates a dual band frequency system, 900MHz, and 2.4GHz. Boasting features such as telemetry, color touch screen display, and great ergonomics, the X20 will surprise many with the value it provides to pilots. The TD dual-band RF system is characterized by true simultaneous dual-band remote control with telemetry, and superb end to end 4ms extreme low latency performance. When combined with ETHOS, a completely new radio operating system, FrSky’s Tandem X20 Series provides users with a powerful, intuitive, and flexible experience to enjoy across the entire world of radio control.

Radio design was top priority for FrSky. Several main points of focus were critiqued greatly during inception, and those methodologies are detailed below.

Hardware Design
The overall weight of Tandem X20 Series has been kept low, less than 1000 grams (~35 ounces), 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 lower case area that allows for quick switching between features, ideal to be used for flight modes, or anything you can dream of. An 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.

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. Lastly, stick tension can be adjusted via the internal springs. 

Internal 900MHz/2.4GHz Dual-Band & External Module Bay
The TD dual-band RF system combines both the features and advantages of FrSky 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 all supported. The built-in TD RF System supports ACCESS and ACCST D16 protocols.
