Overview:
The RadioMaster TX16S MK3 is a high-performance transmitter designed for RC pilots who demand robust control, modern functionality and broad compatibility with built-in ELRS and EdgeTX. It uses a powerful STM32 H7 processor and a vivid 5-inch IPS touchscreen to make model setup, mixing and telemetry configuration intuitive and fast. With an internal dual-band Gemini ExpressLRS module and up to 16 channel support, this transmitter delivers reliable long-range control across both 2.4 GHz and sub-G 900 MHz bands without needing external modules.
Built around a familiar ergonomic layout, the TX16S MK3 adds modern refinements including customisable RGB gimbal light rings, an integrated motion sensor, low-noise cooling and abundant onboard storage. It is an excellent choice for pilots flying multirotors, fixed-wing craft or FPV racers who want cutting-edge capabilities with established open firmware support.
