2. 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.
2.1 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.

This section details functions and their use.
6.1 Reverse
The Reverse function is used to correct a servo or motor's direction in relation to the
systems controls. For example, if a steering servo is mounted upside down in order to fit
inside a model, when the system's steering wheel is turned, the servo will move in the
opposite direction. To fix this, all we need to do is reverse CH1.
Use:
1. Touch the box next to the channels name. If the channel is in normal mode the box
will display "NOR", if it is reversed it will display "REV".
2. Test to make sure everything is working as expected.
6.2 End Points
Endpoints are the limits of the channels range of movement. There are two endpoints,
a low endpoint and a high end point.

when enabled.
6.10 A.B.S.
A.B.S. stands for auto breaking system. This function is used to stop the wheels from
locking which can lead to loss of control or a skid. A.B.S. manages this by regulating the
amount of pressure the breaks use, which is done by pumping the breaks on and off
rather than a constant force.
There are six sub menus for A.B.S. function setting, [Brake return], [Delay], [Cycle
length], [Trigger point], [Duty cycle], and [Steering mix].
In the submenus, pulses are shown as a square wave, the peaks indicating brake on,
and troughs in-dicating reduction in braking. As the value changes, the square wave will
change to represent the function's current
settings.
The trigger point is represented as a white line on the graph.
Below the graph is a bar that shows the real-time braking position. When this function is
active and the brake is applied, the green bar will oscillate in real time showing the A.B.S.
in action.
To activate this function press the
icon. The icon will change to
when active.
Break Return
Controls the reduction of braking during each pulse. If set to 60%, when the
brakes are active; the system will remove 60% of the brakes strength on each pulse.
Delay
Determines how long it takes for the A.B.S. system to take effect. At a setting of 0%, the
A.B.S. system will take effect as soon as the brake is applied. The higher the value, the
longer it will take for the A.B.S. to function.
Cycle Length
Increases or decreases the time between pulses. The higher the
value, the longer the pulse.
Trigger Point
Configures the point at which the A.B.S. starts to function. The
higher the percentage, the further the trigger has to be moved to
activate the A.B.S.
13
Duty Cycle
Changes the length of each pulse and the gap between them. As the value changes,
the length of the braking waves peaks and troughs will change independently of each
other and will no longer be symmetrical.
Steering Mix
A.B.S. can be reduced automatically while turning. This function
mixes braking and steering to turn reduce the A.B.S. or replace it
with a constant braking pressure.v
6.11 Throttle Speed
Throttle Speed changes how quickly the throttle will react, for both braking and throttle.
There are 2 settings for brake and throttle:
•
Go: Sets how quickly the throttle applies acceleration.
•
Return: Sets how quickly the throttle backs off.
The lower the percentage the longer it will take for the throttle to catch up
with the trigger movement.
The bar in the middle of the screen will show the throttle's current position
in real time. The red bar is the triggers current position; the green bar is the channels
current posi-tion.
Setup:
1. Select the desired setting, [Go] or [Return].
2. Use the + or - icons to change the percentage.
3. Repeat with the other settings as needed.
4. Test to make sure everything works as expected.
