FrSky's new Flagship radio is packed with great features and fits your hands like no other!

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.
If you have a windows machine, a free Ethos simulator is available for download if you’d like to dig deeper into the system:

Here are a few more highlights:
24 Channels
6 Quick-Mode Custom Buttons on lower front
2 Momentary finger tip Buttons on the rear (DLG)
External Module Bay for other RF options, etc (Lite Type)
Haptic Vibration Alerts and Voice Speech Outputs
High-speed PARA Wireless Training System
Built-in Bluetooth Audio on S versions (Compatible with wireless headphones and some hearing aids!!)

This transmitter is very well made. I like the touch screen. Programming it was rather easy once you learn the nomenclature. It is very easy once you learn the operating system. The screen stays bright in the direct sun light. It is also easy to us the scroll wheels to navigate the menu. I would highly recommend this unit. It is well worth the money.

Happy with my new Frsky Tandem X20S

This is the first aluminum cased transmitter since my first Tower 4 channel of the mid 1970's. It feels great in the hands and all switches and sticks have the feel you would expect from a high quality transmitter. The touch screen is great and s nice improvement over the Frsky X9D transmitters I have been using for the last 5 years. You will pay much more to get a transmitter of like quality and capability from another company

Perfectly logical upgrade

I used an X10s on OpenTX for the last couple of years and loved it. Only having my new X20s for a couple of weeks now, I'm already impressed with the radio itself for it's ergonomics (although I miss the T5 and T6 trim), and ETHOS is to OpenTX what WYSIWIG was to DOS (if you understand the comparison they you're way too old :-). "Bang for the buck" is an overused phrase, but the X20s makes the high end $$$$ radios of other brands look silly.
