FrSky TANDEM X18S transmitter with EthOS

FrSky TANDEM X18S

Priced for more than $500, the FrSky TANDEM X18S is for sure not intended for everyday FPV drone pilots. I have to admit that it has a UFO design and versatile hardware, but still super expensive for a remote controller!

The FrSky compatible Tandem X18 series dual-band telemetry radios benefit from an enhanced ergonomic design with rounded and more comfortable hand grips, along with an improved case design to make the radio fully stable when standing. The transmitter includes easy-to-reach sliders and switches, 4 standard stick trims with additional 2 extra trims added to provide more flexibility with flight attitude adjustments while operating the radio. Its touchable LCD resolution has a resolution of 480*320 and provides easy access to the menu system.

The FrSky TANDEM X18S is available in two colour options (black and blue) and with two RF standards (FCC – US or LBT – Europe). It comes installed with ETHOS radio operating system and dual-band (900Mhz/2.4Ghz) internal RF module.

Internal 900MHz/2.4GHz Dual-Band & External Module Bay

The TD dual-band RF system combines both the features and advantages of FrSky 900MHz and 2.4GHz RF together in one system. The TD features real simultaneous dual-band long-range control with telemetry that achieves reliable end-to-end 4ms latency while maintaining a robust and high-quality signal link. The entire range of TD, ACCESS & ACCST D16 receivers are supported. The built-in TANDEM RF System supports ACCESS and ACCST D16 protocols.

In addition, the Tandem X18 series radios include a rear Lite version module bay to offer more options to connect external devices. FrSky welcomes working compatibility with the 3rd party products with their own developed technology following FrSky verified 3rd party compatibility-testing program.
