RadioMaster TX16S Mk3 Radio Controller (ELRS)

RadioMaster continues to lead the way in the development of open radio control systems, building on the globally proven concept of the TX16S series. The TX16S MK3 delivers enhanced performance, precision, and ergonomics.

Equipped with the powerful STM32H7 processor, it impresses with rapid response times, smooth operation, and a precise control feel. The bright 5-inch touchscreen with a resolution of 480×800 pixels ensures clear visibility even in direct sunlight and allows for intuitive navigation and easy programming.

Thanks to the new Gemini-X ExpressLRS system with dual LR1121 transceivers, the TX16S MK3 offers a stable and reliable connection over both 2.4GHz and 900MHz – ideal for demanding applications requiring low latency and long range.

The familiar TX16S layout has been retained: all switches, sliders, and potentiometers are exactly where pilots expect them to be. Modular switch panels allow the transmitter to be flexibly adapted to different flying styles.

The standard version of the TX16S MK3 comes with new V6 Hall-effect gimbals featuring four ball bearings, based on the same high-performance chip used in the AG02. External adjustment options for throw, centering, and tension enable precise fine-tuning. Additionally, programmable LED light rings on the gimbals provide visual feedback for flight modes, warnings, or status indicators – while also adding a touch of personal style.

Also available as a MAX version, featuring premium AG02 CNC Hall-effect gimbals made from solid aluminum, CNC-machined aluminum switches and rotary controls, and a refined carbon-look housing for a first-class control experience.
