This full-size transmitter is designed for both FPV pilots and demanding RC enthusiasts, offering a reliable connection, extensive customization options, and a high level of user comfort in every situation.
High-End Performance and Connectivity
At the heart of Radiomaster TX16S MK3 is a powerful STM32H7 processor, ensuring fast response times, a smooth user interface, and enough performance for complex model setups, telemetry, and LUA scripts.
Controller features an integrated ExpressLRS radio system with two LR1121 chips, operating on both 2.4 GHz and Sub-G 900 MHz frequency bands. This Gemini dual-frequency solution enables simultaneous or cross-band operation, delivering an exceptionally stable connection, low latency, and extended range even in challenging environments.
Radiomaster TX16S MK3 supports up to 16 channels and includes a JR-standard module bay, allowing users to connect external RF modules and expand the system according to their needs.
Intuitive User Experience and Software
Radiomaster TX16S MK3 runs on the EdgeTX operating system version 3.0 or newer, known for its flexibility and open-source architecture. It allows users to create complex configurations, customize control logic, and manage multiple models conveniently and efficiently.
On the front panel, controller features a 5-inch IPS touchscreen with an 800 × 480 resolution, providing a clear and high-contrast image both indoors and in bright sunlight. Touch interface makes setup faster and more intuitive compared to traditional button-based solutions.
In addition, the controller includes 4 GB of internal storage and a microSD card slot, allowing users to store models, logs, and custom scripts.
Precise Control and Ergonomics
Radiomaster TX16S MK3 is equipped with V6 Hall-sensor gimbals that use four bearings to provide exceptionally smooth movement, precise centering, and long service life. Mechanical settings such as spring tension and travel range can be adjusted by the user according to personal preference.
Controller design is based on the classic and widely appreciated TX16S layout, where all switches, knobs, and sliders are positioned logically. Replaceable switch panels also make it possible to configure the control layout precisely for a specific use case.
Programmable RGB LED rings around the gimbals add both visual personality and practical functionality, making it possible to display flight modes, alerts, and other status indicators.
Power and Physical Design
Radiomaster TX16S MK3 operates within a 6.6–8.4 V voltage range and supports several power options, including two 18650 or 21700 lithium-ion batteries, or a 2S LiPo battery with a capacity of up to around 6200 mAh.
Controller measures approximately 200 × 178 × 88 mm and weighs around 813 grams without a battery, giving it a robust yet well-balanced feel in hand.
USB-C connection supports charging, data transfer, and simulator use, while wireless connection via Bluetooth is also available.
Summary
Radiomaster TX16S MK3 is a versatile and powerful radio controller, ideal for both advanced hobbyists and professionals. With its dual-frequency ExpressLRS system, large touchscreen, precise Hall-sensor gimbals, and EdgeTX software, it delivers outstanding control, reliability, and customization.
For anyone looking for a future-ready and technically capable solution, the Radiomaster TX16S MK3 is one of the strongest choices in its class.
