Frequently Asked Questions
What is the difference between the FGr4B, FGr4S, FGr4D, FGr8B, and RM005 bundle options?
All bundles include the same NB4+ transmitter. The difference is the included receiver: FGr4B is a standard 4-channel AFHDS 3 receiver with dual antennas, ideal for most RC cars and boats. FGr4S is a slim 4-channel receiver suited for tight chassis installations. FGr4D is a 4-channel receiver with a built-in gyro for drift and on-road cars. FGr8B is an 8-channel receiver for builds requiring more channel outputs. The RM005 bundle includes a multi-protocol RF module instead of a receiver, allowing the NB4+ to control models using other protocols. Dual-receiver bundles are ideal for running two vehicles or having a spare receiver ready.
Is the NB4+ compatible with older Flysky receivers using AFHDS or AFHDS 2A protocol?
No. The Noble NB4+ uses the AFHDS 3 (third-generation) protocol exclusively. It is not backward compatible with older AFHDS or AFHDS 2A receivers. You must use AFHDS 3 compatible receivers (such as FGr4B, FGr4S, FGr4D, FGr8B, or other AFHDS 3 receivers) with this transmitter.
Does the NB4+ support i-BUS2 for servo parameter adjustment and data monitoring?
Yes. The NB4+ supports i-BUS2 protocol, which enables real-time two-way communication with compatible i-BUS2 servos such as the Power HD GTS Series. Via the NB4+ touchscreen, you can remotely adjust servo parameters including stiffness, speed, deadband, center point, and direction. The NB4 Pro version additionally supports data logging of voltage, temperature, and signal for up to 1 hour after racing.
How long does the battery last and how do I charge the NB4+?
The NB4+ features a dual-battery system: a 4300mAh LiPo battery in the handle and a 3450mAh 18650 battery in the removable base, providing extended runtime for long racing sessions. Both batteries charge via the USB Type-C port on the transmitter. Battery life varies depending on usage, but the dual-battery setup significantly extends operating time compared to single-battery transmitters.
Can the NB4+ be used as a simulator controller, and does it support trainer/student mode?
Yes on both counts. The NB4+ supports USB simulator function via its Type-C port (enabled by default), making it compatible with popular RC simulators on PC. It also supports three link modes: Trainer mode (accepts external PPM input to control the model), Student mode (outputs PPM signal only, for use with a trainer transmitter), and H Track mode (connects to a head tracker for FPV use). Two NB4+ units can be linked via a Type-C cable for trainer/student coaching sessions.

Amazing product and excellent shipping by soarsky
Great product...though I have nb4 ...but nb4+ is way better than nb4
Gurpinder Singh
I love my FLYSKY GT5 transmitter and was so distraught when the steering potentiometer started to fail. Luckily a friend mentioned SoarSky and i ordered a replacement and am back to enjoyable RCing

Throttle Ribbon
Throttle broke in my local Hobbies store had it in stock went to replace it in the ribbon got torn. This place is the only place that services these parts. Great service great price had it within a week super happy save me from buying a $350 remote.

Description
FLYSKY Noble NB4+ Surface Radio
This product uses the 2.4GHz Third Generation AFHDS 3 protocol. The Noble NB4+ transmitter and FGr4B receiver constatute a system, compatible with model cars, boats and other models. and it also supports the USB simulator function (Default enabled).
System Features
AFHDS 3 (third-generation automatic frequency hopping digital system) is a newly developed digital wireless system. It is compatible with single antenna bidirectional real-time data packet transmission and data stream transmission. With the advantages that come with the WS2A wireless system and the new 2.4GHz chip, the system can dynamically set: number of channels, channel resolution, range, anti-interference requirements and latency to meet the needs of different users.
| Single Antenna Bidirectional Real-time Data Transmission |
The receiver can receive data from the transmitter and the transmitter can receive data from the receiver, this includes data from sensors, such as temperature and speed and support the i-BUS. This gives more control over the aircraft and constant information on its current status. |
| Uncorrected Data Transmission |
The independent uncorrected data transmission module is built into RF system; it can send many different types of data including flight control data. |
| Intelligent RF configuration |
Depending on hardware, certification, the amount of data to be transmitted, anti-interference, latency and distance requirements, the system intelligently adapts the corresponding RF configuration to meet the requirements of the user. |
| Multi-channel Frequency Hopping |
This systems bandwidth ranges from 2.402GHz to 2.480GHz. This band is divided in 140 channels. Each transmitter hops between 16 channels (32 for Japanese and Korean versions) in order to reduce interference from other transmitters. |
| Unique ID Recognition System |
Each transmitter and receiver has it's own unique ID. Once the transmitter and receiver have been paired, they will only communicate with each other, preventing other systems accidentally connecting to or interfering with the systems operation. |
| Low Power Consumption |
The system is built using highly sensitive low power consumption components, maintaining high receiver sensitivity, while consuming as little as one tenth the power of a standard FM system, dramatically extending battery |

The Noble NB4+ has 2 batteries, one located in the handle and one in the removeable base.
To attach the base:
1. Line up the base so that the transmitter handle has a slight over hang on the back.
2. Carefully insert the base contacts into the hole in the bottom of the handle.
3. Hold the handle firmly and pull the battery backwards. When it is secure you should hear a click.
Noble NB4+ supports three function modes: Trainer, Student and H Track. Transmitters
set to Trainer or H Track Mode accept external signals to control the model, that is, the
trainer interface or head tracker interface has the ability to recognize external PPM
signal input. Transmitters set to Student Mode only output PPM signals and do not
recognize the input signals.
Two transmitters (one for Trainer mode and one for Student mode) can be connected
via a double-ended Type-C cable to realize the coach function.
One transmitter (H Track mode) can be connected to the headset via head tracker
cable to realize the head tracker function.
