Introduction
This product uses the 2.4GHz Third Generation AFHDS 3 protocol. The NB4 and FGr4 constatute a 4 channel system,
compatible with model cars, boats and other models.

System Features
AFHDS3 (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 life.
