FrSky TANDEM X20R Dual-Band Radio with TD-ISRM RS RF Module for Fixed-Wing and Turbine Jet Aircraft

The TANDEM X20R is a specialized variant of the X20 series built specifically for fixed-wing aircraft, gliders, and turbine jet models. The key difference is the included TD-ISRM RS RF module, which supports dual-band 900MHz and 2.4GHz simultaneous transmission (TANDEM protocol). The 900MHz band provides significantly longer range and better signal penetration through airframes compared to 2.4GHz alone - critical for high-speed jets and long-range fixed-wing flights where signal reliability at distance is paramount. The upgraded external LoRa antenna connectors and redesigned antenna handle further optimize signal performance for these demanding applications.

The X20R with TD-ISRM RS module supports multiple protocols: TW (TANDEM dual-band 900M+2.4G), TD (TANDEM 2.4G only), ACCESS (FrSky's advanced 2.4G protocol), and ACCST D16 (legacy FrSky protocol). This means it is backward compatible with most existing FrSky ACCESS and ACCST D16 receivers, while also supporting the latest TANDEM dual-band receivers for maximum range. If you are upgrading from an older FrSky system, your existing receivers will likely work in ACCESS or ACCST D16 mode.

The X20R is equipped with M20 high-precision Hall sensor gimbals, which use magnetic field sensing instead of traditional potentiometers. Hall sensor gimbals are contactless, meaning there is no physical wear over time, resulting in consistent precision throughout the lifespan of the transmitter. They provide smoother, more accurate stick movement with better centering repeatability - critical for precise control of fixed-wing aircraft, especially during landing approaches and aerobatic maneuvers.

Yes. The X20R features a built-in 6-axis gyroscope. This enables head-tracking functionality and can be used for stabilization mixing in compatible setups. For fixed-wing pilots, the gyroscope data can be used with FrSky's flight stabilization systems to assist with attitude hold and stabilized flight modes, particularly useful for turbine jet models where precise attitude control is critical during high-speed passes.

The Cherry Red, Blackish Green, and Slate Gray variants are priced the same. The White and Chameleon color variants are priced slightly higher due to their premium finish. All color variants share identical internal hardware, RF performance, and specifications - the difference is purely cosmetic. Choose the color that best suits your personal style or matches your aircraft livery.
