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 900MHz 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:
The overall weight of Tandem X20 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 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.
The two side handle grips of Tandem X20 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 and the stick travel (45°to 60°) can be adjusted. (S & HD versions support rotating gimbals within adjustable L/R 8°).
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 supported. The built-in TANDEM RF System supports ACCESS and ACCST D16 protocols.
