Why Pilots Choose the TX16S MKIII ELRS

Powered by an advanced STM32H7 processor, the TX16S MKIII delivers quick input handling, responsive menus, and dependable performance for demanding RC users. The bright 5-inch IPS display stays clear and readable even outdoors, making setup and field adjustments easy.

With its Gemini-X ExpressLRS system using dual LR1121 transceivers, the TX16S MKIII offers exceptionally reliable, low-latency control across both 2.4 GHz and 900 MHz bands. For hobbyists who value confidence, range, and connection stability, this is a major advantage.

The standard V6 Hall sensor gimbals feature a four-bearing design and use the same chipset as the AG02, helping deliver impressive precision and smooth stick feel. External adjustment points for throw, centering, and spring tension make fine-tuning easy. On top of that, the programmable RGB LED rings let you assign flight modes, alerts, or status indicators while adding a custom look to your radio.

The full-size chassis keeps the classic TX16S layout loved by pilots around the world. Every switch, slider, and potentiometer is positioned for confident operation and full control. Thanks to the modular switch side panels, you can adapt the setup to match your preferred flying style.

Every detail of the TX16S MKIII reflects thoughtful refinement — more power, better ergonomics, and a design built for RC pilots who expect premium performance from their gear.
