FrSky Tandem X20 Hall Sensor Gimbals Built-in 900M/2.4G Dual-Band Internal RF Module Mode2 Radio Transmitter ETHOS Touch-Screen PARA Wireless Training System for RC Drone Precise details: -Note: If you live in an EU country, please be sure to choose the LBT version, otherwise there will be incompatibility -OVERVIEW: 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 colors 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: - Hardware Design The overall weight of Tandem X20 Series 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 colors 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 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 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, also the spring tension and the stick travel (45°to 60°) can be adjusted. - Internal 900MHz/2.4GHz Dual-Band & External Module Bay In addition, the Tandem X20 Series includes a rear Lite version module bay to offer more options to connect external devices. The external Lite module bay supports R9M Lite, R9M PRO Lite, XJT Lite, etc. FrSky welcomes working compatibility with the 3rd party products with their own developed technology following FrSky verified 3rd party compatibility-testing program. - ETHOS Operating System ETHOS, as a thoroughly new operating system, designed from the ground up by RC experts, grants users a powerful, intuitive, and flexible experience that can maximize the fun of RC Hobby -Specifications: Brand Name: FrSky Item Name: X20 Transmitter Model: X20 Dimension: 212*200*95 mm (L*W*H) Weight: 809g (without battery) Mode: Mode 2 (Left Hand Throttle) Color: Blue/Black Version: Non-LBT(FCC 915MHz)/LBT Version(EU 868MHz) Please notice, antenna is different for FCC and EU.
