Radiomaster TX16S MK3 Radio Controller (ELRS / M2)

The RadioMaster TX16S MK3 is the evolution of a legendary series, setting new standards for processing power and link redundancy in modern RC and FPV piloting. Driven by an ultra-powerful STM32 H7 processor architecture, this radio transmitter delivers lightning-fast input responses and completely fluid operating system navigation. The definitive engineering milestone of the MK3 is its built-in dual-band ExpressLRS Gemini transmission system, which transmits simultaneously on both 2.4GHz and 900MHz frequencies to ensure unprecedented signal safety in high-interference environments.

Features

Next-Gen Processing Overhead: Powered by a high-performance STM32 H7 core to achieve zero interface lag, quick Lua script processing, and near-instant profile shifts.

High-Definition Touchscreen: Large 5.inch IPS color touch display running an 800x480 resolution with premium panel brightness for flawless visibility under heavy ambient sunlight.

Dual-Band Gemini Transmission: Integrated dual LR1121 chipsets driving a true ExpressLRS Gemini setup for simultaneous 2.4GHz and 900MHz transmission, ensuring flawless link reliability.

V6 Multi-Bearing Hall Gimbals: Upgraded V6 Hall-effect gimbals riding on quad bearings to provide elite AG02-level accuracy alongside externally adjustable stick travel and spring tension without opening the case.

LUA-Controlled RGB Gimbal Rings: Programmed multi-color LED rings around the stick assemblies acting as dynamic visual indicators for flight telemetry, warning prompts, or chosen flight modes.

Active Thermal Mitigation: Low-noise cooling fan array combined with a massive aluminum block heatsink preventing RF output degradation or thermal throttling over long sessions.

Integrated Flight Gyroscope: Onboard motion tracking sensor enabling raw tilt-axis mapping to control external camera pan-and-tilt hardware or trigger customizable auxiliary layouts.

Modular Switch Panels: Redesigned faceplate layout allowing pilots to easily pull and alternate physical switch configurations to best fit custom finger ergonomics.
