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.
