FLYSKY Noble NB4+ Surface Radio w/ Receiver FGR4B
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.
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.

Customer Reviews
Great service. Fast shipping and well packaged. RTC battery was dead in Frsky X20, when I received it. However, this seems to be something that Frsky knows and has since addressed. Although, mine was dead. Other than that, everything was great. Will definitely do business with Helidirect again!
So far the item is good I haven’t done anything to see how it is. But once I do it I’ll say my review then but for now is a 4 star.
Only had the noble NB4 + For a couple weeks. So far there is nothing I do not like about the radio. Fast shipping good Price. Would recommend this Radio does everything you need to do.
It’s easy to program, fast response time, and very comfortable to use and hold.
Purchased to upgrade from my old Spekrum DX and have been truly impressed by the improved response on my cars. Also happy with screen visibility and menus are straightforward.
