Flysky Noble NB4+ 2.4GHz 8CH Radio Transmitter - Compact Touchscreen

Our review of the Flysky Noble NB4+ finds it aimed at hobbyists who want a modern, feature-rich ground transmitter without jumping to pro-level price. The single biggest reason to buy is its combination of a bright 3.5'in IPS touchscreen and low-latency 2CH Ultra-fast mode, which delivers precise responses for cars and boats during critical maneuvers. This review focuses on usability, build, radio performance and the practical benefits of the NB4+ in real RC use.

Key Features

• 3.5'in IPS display: A 320x480 full-dot matrix screen stays readable in strong outdoor light so you can make setup changes on the fly.
• Ultra-low latency mode: The 2CH Ultra-fast option gives very responsive control for tight driving or racing moments where timing matters.
• Quick release battery design: The standard large-capacity removable battery and charging base offer marathon-friendly runtime for long sessions.
• USB Type-C data interface: Stable connections for online updates, coach mode teaching and head tracking through the Type-C port add versatility.
• Wide device compatibility: Supports FlySky i-BUS2 devices and select Hobbywing and Power HD gear, enabling transmitter-side parameter adjustment.
• Customizable UI: A colorful interface with theme and wallpaper options makes the unit feel modern and personal.

Who It's For

The NB4+ suits RC car and boat enthusiasts who want an ergonomic, well-built radio with a touchscreen and advanced features like head tracking and coach mode. It is a good choice for intermediate pilots and drivers upgrading from basic radios who value display visibility and low latency control.

Those who need large professional transmitter ecosystems, multi-model memory for dozens of airframes, or integrated lithium battery shipping included should look elsewhere; the NB4+ ships without standalone lithium cells and is positioned as a high-value ground transmitter rather than a full-scope pro system.
