Details

Built around the familiar TX16S layout, the TX16S MK3 adds a 5-inch IPS touchscreen and dual-band ExpressLRS for flexible setups.

An STM32H750 (H7 series) MCU delivers fast response for menus, model setup, and telemetry-driven flying.

A bright 800×480 IPS touchscreen gives plenty of room for widgets, telemetry, and quick adjustments.

Gemini dual-band ExpressLRS uses dual LR1121 chips to support both 2.4GHz and Sub-G 900MHz.

V6 Hall gimbals with quad bearings are adjustable without disassembly, with LUA-controlled RGB gimbal light rings.

A full set of switches and sliders stays in the classic TX16S positions for an intuitive feel.

Replaceable shoulder switch panels and a JR-style module bay keep the transmitter easy to customize over time.

Low-noise fans and an aluminium heat sink help manage heat during extended high-power sessions.

Smart active balance charging helps prevent overcharging and supports common 18650 cell setups.

Onboard flash memory is complemented by a microSD card slot for added storage (card not included).

A built-in motion sensor enables X-tilt and Y-tilt controls for compatible models and functions.

Twin foldable antennas are designed to deliver strong dual-band signal performance.

One USB-C port handles simulator connection, data transmission, and charging.

Key specifications are provided for quick comparison, including firmware, RF system, display, and size.

A full-size transmitter body measures 200×178×88 mm for a stable, comfortable grip.

Everything needed to get started is included, such as the signature carry case, USB-C cable, and 18650 battery tray.
