The Flysky Noble NB4 Pro+ is a premium 2.4GHz 18-channel radio transmitter designed specifically for RC car, boat, and robot enthusiasts. It succeeds the original NB4 Pro, offering enhanced channel capacity, ultra-low latency, and a suite of professional features tailored for competitive and complex builds. 

Key Features and Performance

The transmitter distinguishes itself with an 18-channel capacity (selectable from 2 to 18), making it ideal for scale crawlers, construction vehicles, and complex marine models requiring multiple servos.  It utilizes the AFHDS 3 protocol for interference-free communication and features a 2-channel ultra-fast mode with latency as low as 3ms, a specification often cited by world champions for competitive racing.  The system supports bidirectional telemetry, allowing users to monitor real-time data such as battery voltage, temperature, and signal strength. 

Display and Interface

The unit is equipped with a 3.5-inch IPS high-brightness touchscreen with a 320x480 resolution.  This display is designed to remain clearly visible under direct sunlight. The user interface is fully customizable, allowing for theme changes and wallpaper adjustments, and supports custom channel naming for intuitive control mapping. Navigation is handled entirely through the touch interface, eliminating the need for physical scroll wheels found on older models. 

Power and Connectivity

The NB4 Pro+ features a dual-battery system comprising a 4300mAh lithium polymer battery in the handle and a swappable 3450mAh 18650 battery in the base, providing over 18 hours of operation.  It includes a wireless Qi charging dock for convenient recharging without plugging in cables.  Connectivity is modernized via a USB Type-C port, which supports firmware updates, simulator connections, coach mode for teaching, and head-tracking functionality.

Package Contents and Differences from NB4+

The Pro+ model is positioned as a premium bundle compared to the standard NB4+. Key upgrades include the increase from 8 to 18 channels, the inclusion of a Beginner Mode for new drivers, and a comprehensive accessory kit.  The package typically includes:

• The NB4 Pro+ Transmitter

• FGr4B (4-channel) and FGr8B (8-channel) AFHDS 3 receivers

• Wireless charging base

• Carbon fiber aesthetic hard carrying case

• Dual batteries (LiPo and 18650) 

In contrast, the standard NB4+ is limited to 8 channels, lacks the beginner mode, and does not include the wireless charging dock or the premium carrying case.
