RadioMaster TX16S MKII Hall V4.0 ELRS LBT Controller
The RadioMaster TX16S MKII Hall V4.0 ELRS LBT represents the pinnacle of transmitter engineering — combining cutting-edge RF technology, user-friendly design, and unmatched precision. Whether you’re flying FPV quads, fixed-wing aircraft, or professional UAVs, the TX16S MKII delivers total control and confidence in every mission.
TX16S MKII – engineered for pilots who demand perfection.
The RadioMaster TX16S MKII Hall V4.0 ELRS LBT is a flagship-grade transmitter built for FPV pilots and professional drone operators who demand maximum performance, flexibility, and precision. Designed around the powerful EdgeTX firmware, the TX16S MKII combines intuitive touchscreen operation, robust wireless connectivity, and superior ergonomics — making it one of the most advanced transmitters on the market.
This model comes equipped with an internal ExpressLRS (ELRS SX1280) RF module, capable of up to 250mW of adjustable transmitting power, ensuring ultra-low latency and exceptional long-range performance beyond 2 kilometers. For users who prefer wider protocol compatibility, an alternative configuration with a 4-in-1 multiprotocol module (CC2500, CYRF6936, A7105, NRF2401) is also available, supporting a wide range of receiver systems.
The TX16S MKII features V4.0 Hall-sensor gimbals with aluminum fascia (AG01 CNC gimbals optional) that deliver buttery-smooth precision and long-term durability. The 4.3-inch full-color TFT touchscreen (480×272 resolution) provides a clear, intuitive interface for flight setup, telemetry, and model management — all navigable via both touch and physical controls.
Weighing just 750g (without battery), the TX16S MKII remains comfortable during long sessions thanks to its balanced design, textured grips, and easily accessible switches. It includes a 256MB SD card (expandable up to 8GB) for data storage, model backups, and firmware updates.
