Why this matters: your FpV drone controller shapes every flight. The TX16S MK3 packs Gemini X, H7 horsepower and lots of switches into one new shell.
TL:DR
The TX16S MK3 is a full redesign. It adds STM32H7 performance, a 5" IPS touchscreen, dual LR1121 ExpressLRS Gemini X, AGO2 gimbals and smarter ergonomics.
What you need to know
RadioMaster rebuilt the TX16S from the ground up. This isn’t a cosmetic refresh; it’s a new platform aimed at multi-discipline pilots.
Screen and UI
The new 5" IPS touchscreen runs at 800×480. EdgeTX benefits from the H7 CPU, and the screen has an ambient light sensor for auto-brightness.
Radio hardware — ExpressLRS and Gemini X
RadioMaster fitted dual LR1121 chips. Either side can run 868/900 or 2.4GHz, giving full Gemini X capability and up to 1W per output.
Antennas and module bay
Two antennas handle dual-band operation: an articulating top antenna and a hidden antenna inside the folding handle. There are holes for external SMA mounts.
Controls, switches and LEDs
Front programmable buttons now sit beneath the screen. Set each to an individual channel and change LED colours via EdgeTX.
Gimbals and ergonomics
The Max model ships with AGO2 CNC gimbals. They feel premium — better sensors, simpler adjustment, and LED rings configurable per model.
Battery, charging and storage
The battery bay fits two 18650 cells or RadioMaster Li‑ion packs. The radio includes smart battery management and USB-C charging at roughly 10W.
Teardown highlights
Inside sits an STM32H750 core module, removable PCB layout, a heatsinked RF module with fan, and a rechargeable backup battery.
How it compares
Compared to the original TX16 and the TX15, the MK3 keeps the TX16 switch count but borrows the TX15’s silicon and GX12’s RF smarts.
Unboxing essentials
The Max package includes a soft case, switch caps, neck strap and a USB charging cable. Batteries usually ship separately.
Verdict
The TX16S MK3 is RadioMaster’s new top-tier radio. It fixes the TX16’s ergonomics and folds modern features into a single FpV drone-friendly unit. Buy your TX16S MK3 from Unmanned Tech
If you fly planes, boats, cars or FpV drone rigs and want one radio that covers everything, this is the practical choice.
FAQ
Does the MK3 support Gemini X on both modules?
Yes. Dual LR1121 chipsets allow either module to run 868/900 or 2.4GHz, including Gemini X configurations.
What CPUs run the radio and EdgeTX?
The MK3 uses an H7-class STM32 MCU similar to the TX15. It handles modern EdgeTX UI and touch functions smoothly.
Are the sliders still available?
Yes. Sliders moved to the radio’s back corners, with detents and easier reach whether you thumb or pinch.
