A Very Thorough Radio Design 

Tandem X20 Series design has focused highly on technology, ergonomics, and user experience as follows:


Hardware Design
Using state of the art light-weight materials, the overall weight of Tandem X20 is almost weightless. Weighing at less than 1kg, this design retains its strength and robust quality whilst staying light and easier to hold for long periods of time. 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, ideal for flight modes, this allows for quick switching between features. 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°/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.

TD Internal RF Modules Compatibility
2.4G ACCST D16Mode Compatible with ACCST Receivers with D16 V2 or later FW
