FrSky TANDEM X20S Manual

Introduction

The Tandem X20S is a pioneering dual-band radio transmitter, it drew on feedback and experience with previous
radios and adds many new features such as color touch screen, an ergonomic design that provides unprecedented
comfort in the hand. On the RF side, we have given it the powerful RF system , the TD dual RF system, which does
not simply reiterate the combined features of the FRSKY900MHz and 2.4GHz RF systems. The TD is characterized
by its true simultaneous dual-band remote control with telemetry, enabling incredible and unmatched end-to-end
4ms latency. This radio ships with Ethos, a completely new system that provides users with a powerful, intuitive, and
flexible experience that maximizes the fun of the hobby.
