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 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.

Ergonomics

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°).
