Details
The NB4 Pro+ refines the exterior with a redesigned handwheel and a gunmetal-gray finish aimed at competition driving feel.
Upgrades include a 3.5-inch color IPS touch display, a removable built-in battery, and USB Type‑C for charging and data output.
Software tools add trainer/coach support, head-tracking settings over USB, and expanded model memory for multi-vehicle setups.
Compatibility support is geared toward Mini‑Z users, with transmitter options for binding, updating, and FHSS programming workflows.
Module and receiver options help match the radio setup to different Mini‑Z configurations and FHSS receiver types.
Key specifications cover AFHDS 3 protocol support, selectable channel counts up to 18 (optional), and the built-in 3.5-inch IPS touch screen.
A large-capacity 18650 battery and USB Type‑C interface support long run times plus data output features for advanced control setups.
A high-density handwheel sponge improves grip feel, while the high-brightness IPS display is designed for clearer outdoor viewing.
On-radio menus provide quick access to telemetry-style functions and parameter tuning such as gyroscope adjustments.
Built-in data recording and i‑BUS2 parameter settings streamline tuning without leaving the transmitter interface.
For racing setups, 2CH turbo mode and high-speed i‑BUS2 support prioritize responsive control inputs.
Logic switch options expand how channels and functions can be combined for more customized control behavior.
Protocol and RF selections help tailor the transmitter to different receiver outputs and compatible system modes.
Condition modes make it easier to switch between driving profiles like dual rate, curves, ABS, trims, and channel speed settings.
Precision-focused calibration aims for steadier input tracking and smoother linear response at the wheel and trigger.
