Details

The Joshua Bardwell Edition TX16S Mark II Max pairs a carbon-fiber look with purple CNC accents and EdgeTX-ready hardware.

A large IPS touch display and full-size controls make model setup and flying adjustments quick and intuitive.

Choose the internal ExpressLRS option or the 4-in-1 multiprotocol version to match your receiver ecosystem.

V4.0 Hall sensor gimbals offer smooth control, stable centering, and tool-accessible adjustments without disassembly.

Fine-tune stick travel, spring tension, and self-centering behavior to match your preferred flying style.

Swappable raised or flat rear grips help dial in comfort for different hand sizes and pinch or thumb control.

Built-in dual speakers provide clear audio prompts without needing headphones.

A JR-style external module bay keeps upgrade paths open for pilots who want to add a separate RF module.

EdgeTX Companion lets you manage model profiles and radio settings from a computer for faster setup and backups.

Improved sliders with center detents make it easier to hit repeatable settings for cameras, flight modes, or mixes.

Center-detent S1/S2 knobs and a responsive touch screen improve accuracy when navigating menus and making changes.

Convenient access points include a 3.5mm headphone jack, an easier battery cover, and a rear DIY/accessory socket.

USB connectivity supports data tasks, while the 3.5mm TRS trainer socket enables buddy-box training setups.

Ports are grouped for easy access to charging, SD card storage, and expansion via the UART interface.

A full control layout with six-position switches, sliders, and dedicated buttons supports complex model mixes and workflows.

Skip internal RF-module complexity with built-in ExpressLRS for fast response and broad receiver compatibility.
