The FrSky TWIN X-Lite RII is a compact, lightweight and highly capable 2.4GHz radio transmitter designed for modern RC pilots who demand reliable long-range communication, low latency and flexible protocol support.

At the heart of the TWIN X-Lite RII is FrSky's dual 2.4GHz TWIN TW system, which operates two 2.4GHz frequency bands simultaneously when paired with a compatible TW receiver. This active-active architecture is designed to provide enhanced RF resilience, higher reliability, faster data rates and latency below 4ms while maintaining full telemetry support.

The transmitter also supports ACCST D16 and ACCESS, giving pilots a broad selection of compatible FrSky receivers for different aircraft and applications.

The RII features four integrated 2.4GHz antennas positioned for improved RF performance, together with an upgraded sliding-screen mechanism. Its 3.5-inch 800 × 480 high-brightness touchscreen is designed for improved visibility outdoors, while the compact ergonomic form makes the transmitter easy to carry and comfortable to operate.

Input controls include six trims, four customisable quick-mode buttons and two upgraded top sliders with centre detents and damped feedback. The CNC metal gimbals incorporate high-precision Hall sensors and upgraded anti-slip spiked stick ends for confident control during normal flying and racing.

An integrated 6-axis sensor allows the transmitter to be used as a motion-sensing controller for compatible applications. Built-in 512MB flash storage provides ample space for radio files, models and system data, with an external TF card slot available for additional storage.

The TWIN X-Lite RII runs FrSky's ETHOS operating system, includes haptic vibration and voice alerts, supports PARA wireless training and features a rechargeable 2S Li-Po battery system with USB Type-C charging.
