FrSky has achieved the impossible with the new X20 and X20S radios. They are extremely powerful yet easy to use. We are very comfortable suggesting the X20 radios to all of our customers, it is that good.
The FrSky Tandem X20 Series is a dual-band telemetry radio that features a color touch screen display, ergonomic design, Tandem dual-band RF system (2.4 & 900), and most importantly Ethos – Frsky’s newest operating system. It boasts an impressive end-to-end latency, ergonomic design featuring low weight and a thin profile, natural switch, button, and slider positioning, excellent durability and metal hall effect gimbals. The X20S features rotatable gimbals to best customize the radio to your grip style.
The biggest innovation in this radio lies in its software, Ethos, which has been designed from the ground up to encapsulate the power and flexibility of OpenTX while retaining the ease of use and user interface of a menu-driven system. It features customizable elements such as sounds, model images, and splash screens, while also including an easy to use setup wizard, tips while programming, along with preset and complex mixing options and flight modes. Ethos makes quick work of programming simple planes or something complex like a full-house glider. If you are familiar with OpenTX, Ethos will feel really familiar but faster and easier to use. If you are coming from a menu-driven system, Ethos is a supremely powerful and easy to learn software that will have you up and running in no time. We like to say that Ethos can do whatever you can think of for a radio to do! Yeah, it can do that.
The X20/S also boasts some features new to FrSky radios. A crisp and responsive 800 x 480 touch screen that is easily visible in sunlight, backed by a more powerful CPU. If you prefer button navigation, full functionality is still available through the normal nav buttons, so no need to touch the screen.
USB-C charging (2A+), an included 4000mah Li-Ion battery pack, a 6-axis Gyro sensor (for controlling those pesky takeoffs with body language), and FrSky’s robust telemetry system with a huge selection of receivers to meet any need.
For those that may be new to FrSky, you will be getting the most robust telemetry system ever built into a hobby level radio. From simple voltage and signal strength monitoring that has helped avoid countless accidents to advanced features like monitoring amp loads for an individual servo, fuel flow sensors, air speed, and so much more, you will not find a better telemetry system in the hobby.
