The Flysky Noble NB4+ has become one of the most recommended surface transmitters in the Australian RC market because it delivers professional-level performance at a price accessible to everyday hobbyists.

Redefining Control Precision

One of the biggest strengths of the Noble NB4+ is its advanced AFHDS 3 transmission protocol. This system provides faster, cleaner and more stable communication between the transmitter and receiver, giving drivers noticeably smoother and more predictable input control.

Key control advantages

• High-speed digital signal processing

• 4096-step resolution for precise throttle and steering

• Low-latency response ideal for racing environments

• Strong signal stability on crowded tracks

For drivers upgrading from RTR transmitters, the difference in control feel can be dramatic. The NB4+ allows cleaner corner entries, more controlled braking and better throttle modulation, especially on high-grip surfaces.

Modern Touchscreen Interface

The Noble NB4+ moves away from traditional scroll wheels and button menus. Instead, it features a full 3.5-inch HVGA IPS touchscreen, providing a highly intuitive interface similar to a modern smartphone.

Usability benefits

• Fast access to all driving parameters

• Easy model memory setup

• Clear menus and logical navigation

• Bright screen suitable for outdoor conditions

This makes configuration significantly faster, whether you are binding a new vehicle, adjusting steering rates or setting up mix functions. For hobby shops, clubs and families managing multiple drivers, the touchscreen interface saves time and eliminates confusion.

Ergonomic Design for Extended Driving

Comfort is a major factor in choosing a transmitter, especially during multi-hour track days. The NB4+ is designed with ergonomics in mind, offering a comfortable grip and well-balanced feel.

Ergonomic highlights

• Lightweight balanced structure

• Adjustable wheel position for left- or right-handed drivers

• Stable rechargeable base

• High grip textures for secure handling

Drivers who spend long sessions racing or crawling will notice reduced hand fatigue compared to heavier or poorly balanced radios.

Eight-Channel Flexibility for Any RC Setup

Although many RC cars only use two channels, the NB4+ supports up to eight. This makes it suitable for a wide variety of vehicles and advanced builds.

Ideal for

• Drift cars with gyro tuning

• Scale crawlers with lights and winches

• Boats or multi-function models

• Instructor and beginner mode setups

• Multi-model garages needing one transmitter

This flexibility ensures the NB4+ remains useful as your RC collection grows, reducing the need to buy additional radios in the future.

Built for Australian Outdoor Conditions

Australian RC environments can be tough. Heat, dust, and humidity can affect electronics, especially during off-road or summer racing events. The NB4+ is designed with robust environmental tolerances to remain reliable in real-world use.

Durability strengths

• Operating range from -10°C to +60°C

• Humidity tolerance up to 95 percent

• Solid chassis and grip materials

• Reliable signal performance outdoors

This makes the NB4+ suitable for basher parks, club tracks, trail crawling and long meetups.

A Strong Upgrade Path for Beginners and Racers

The Noble NB4+ provides an ideal step up from RTR radios without moving into extremely high-end pricing. For beginners who want improved control or intermediate drivers entering club racing, this transmitter offers significant performance gains.

Ideal upgrade scenarios

• Improving a Tamiya TT-02 or TT-02B

• 1/10 buggy racing

• 1/10 touring car performance

• 1/8 off-road bashing

• Drift or crawler accuracy tuning

It balances capability, usability and affordability better than many options in its category.

Receiver Options and Expansion

The NB4+ is compatible with Flysky AFHDS 3 receivers, including the popular FGr4B and FGr8B models. These receivers are compact, reliable and inexpensive, which is especially helpful for users with multiple RC vehicles.

Model memory allows drivers to manage several cars quickly, making the NB4+ practical for anyone who owns more than one RC platform.
