FrSky TANDEM X18 & X18S & X18SE Manual

Introduction

When you are investing in a new radio and considering what requirements are important to you, if weight and
comfort are primary considerations, followed by the benefit of the excellent system features of ETHOS, then the
FrSky Tandem X18(S) radio is an obvious appropriate choice.
The Tandem X18(S) dual-band telemetry radio benefits 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
radio 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. The X18(S) includes further
enhancements with integrated flash storage which improves and simplifies storage operation and use, and the
interior of the radio has been designed with space and weight in mind, while still keeping all ETHOS setting and
control features for the pilot to enjoy.
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 longrange 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(S) includes 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.
