Radiomaster TX16S MK3 MAX Radio Controller - Red

Our current stock of Radiomaster TX16S MK3 radios comes with 4GB internal memory.

Radiomaster has officially announced a transition to 512MB internal flash for all future production of the TX15 and TX16S MK3 radios.

All orders up to now are covered with 4GB units. Once this batch is sold out, incoming radios will feature 512MB internal memory.

If you prefer the 4GB version, now is the time—once these are gone, they’re gone.

There are no changes to performance or functionality. The 512MB version remains more than sufficient for normal use, and all radios continue to support external SD cards.

RadioMaster builds on the globally trusted TX16S legacy, continuing its commitment to open-source RC innovation. Built for pilots who expect more, the TX16S MK3 MAX represents the pinnacle of the TX16S platform—combining the proven full-size layout with premium materials, advanced controls, and uncompromising attention to detail.

Powered by the advanced STM32H7 processor, it offers lightning-fast performance, smooth operation, and instant responsiveness. The bright 5-inch 800×480 IPS touchscreen provides a sharp, sunlight-readable interface for easy navigation and programming.
