HD Digital Video Transmission System

FrSky Tandem X20S series HD UpKit Version radio system provides the perfect solution for FPV flying and pilots preferring an easier operation with fewer devices. The HD version of the X20S HD UpKit Version radio system includes an integrated FPV screen supporting 720p 60FPS video quality, removing the need for a standalone FPV screen. When combining the HD 720p 60FPS video with near 0ms low latency digital video transmission technology, the X20 HD radio will provide more enjoyment and confidence when FPV flying tours. The built-in video receiver module is compatible with all HDZero video transceiver (VTX) products.

The X20S HD UpKit Version radio package includes a 5.8G antenna kit. The circularly polarized directional antennas ensure that the radio receives optimum video transmission signals, even in complex RF environments. The HD version of the X20S HD UpKit Version radio also provides an HDMI output which can be used to easily transfer the HD video to an external monitor or device if required, this provides a great solution if you wish to use your existing FPV goggles which support HDMI-in, removing the need for separate HDZero video receiver attached to your goggles.

The Tandem X20S HD UpKit Version series

The FrSky Tandem X20S HD UpKit Version 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.

A Very Well Thought Through Radio Design

Tandem X20S HD UpKit Version Series design has focused highly on technology, ergonomics, and user experience as follows:

Hardware Design
The overall weight of Tandem X20S HD UpKit Version has been kept low 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 X20S HD UpKit Version 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 X20S HD UpKit Version 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
