Introduction

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).

2.1 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 The independent uncorrected data transmission module is built into RF system; it can send Transmission 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

6.6 ABS
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 will change to when active.

Website

Break Return Controls the reduction of braking during each pulse. Can be set to any value between 0% and 100%. By default it is set to 50%. 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. When set to 0% there will be no delay, meaning the breaks will be applied as soon as they are triggered. The maximum setting of 100% will result in a delay of 2 seconds.
Cycle Length Increases or decreases the time between pulses. The higher the value, the longer the pulse. The maximum setting of 100% will result in a cycle length of 0.5 seconds.
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. 0%-100% represents the entire stroke of breaking servo.
Duty Cycle Changes the length of each pulse and the gap between them. Adjustment range is from-4 to +4 cycles. 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. Adjusting the brake to release ratio When the period is set to “0”, the ratio is 1: 1; When the period is set to “1”, the ratio is 1: 2; When the period is set to “-1”, the ratio is 2: 1.

Neutral Calibration
Used for gyroscope to calibrate steering and throttle neutral to make the best driving condition when the vehicle is driving normally. Before enabling the SVC function, you need to adjust the vehicle’s steering servo volume, neutral trim and throttle neutral to the best driving condition. After completion, start the [Smart Vehicle Control] function for neutral calibration. Every time you change the trim or throttle curve, you need to calibrate the neutral position. The steering throttle should be placed in the neutral stationary state during the calibration process.
Reverse You can set the direction when the gyroscope mixes with the steering channel.
ESP Mode Used for model assisted stability. Two modes are available: normal/lock. [Normal]: When the vehicle is yawing or steering, the gyroscope automatically provides an opposite compensation to control the servo to keep it stable or prevent drifting according to the angular velocity generated. [Lock]: If the steering wheel is return-to-center, the gyroscope will control the servo in the opposite direction according to the yaw angle when the vehicle is yawing, to make it go back to the expected direction (if the steering wheel is not return-to-center in the “Lock mode”, it will be the same as the “Normal mode”).
Steering Gain Used to change the sensitivity of the mixing steering channel. And the setting range is between 0% and 100%.
Throttle Gain Used to change change the sensitivity of the mixing throttle channel. And the setting range is between 0% and 100%.
Priority
Used to set the control ratio between steering wheel control and gyroscope in the steering, i.e., turning radius. In direction turning by using the steering wheel, the steering angle will be reduced due to the influence of gyroscope mixing. When the value is 0%, the mixing control is the strongest, that is, the turning radius is the largest. When the value is 100%, the mixing control is 0, that is, the turning radius is the smallest. And the setting range is between 0% and 100%.
Gyroscope Calibration Used for the first time to enable the gyroscope via binding or gyroscope calibration required after replacement.The model keeps a stable and stationary state. Click calibration. The receiver flashes twice and exits automatically. This indicates that the calibration is successful. (The above are the adjustable parameters when the transmitter is adapted to the GMr receiver and FS-GY01 gyroscope, and it is also adjustable when it is adapted to the

Notes: 1. Users need to prepare the cable for the Trainer function (dual-ended Type-C cable) and the cable for the Head
Tracker function (Type-C port on one end and audio port on the other end in advance). · If users do not have a suitable head tracker cable, the FS-XC201 Type-C cable can be used to change the
cable according to the definition of Type-C cable sequence, retaining the Type-C connector of the Type-C cable. Use a plier and other tools to cut off the other end of the Type-C cable, and lead out the wire cores wrapped by the Type-C cable. The user confirms which two wires are the ground line (GND) and the signal line (PPM). Generally, the black wire core is the ground line and the white wire core is the signal line. It is subject to the actual measurement of the wire sequence. · Take the S-terminal of the head tracker interface as an example. Before rewiring, you need to confirm the pin definition of the S-terminal, so as to lead out the earth wire (GND) and signal wire (PPM) wrapped in the head tracker cable. The steps are similar to those of rewiring FS-XC201 Type-C cable. Keep the S-terminal connector of the head tracker cable, cut off the other end with a plier and other tools, and lead out the cores wrapped in the head tracker cable, and then connect the two cores of the FS-XC201 Type-C cable with the two cores of the head tracker cable. Then you can use the head tracker function normally (the GND line connects to the GND line, and the Signal line connects to the signal line). · Take the 3.5mm head tracker interface as an example. Choose 3.5mm Type-C cable to change to 3.5 mm audio port adapter cable. You need to confirm in advance whether the audio port of the FPV glass outputs PPM signals (For details, check FPV glasses manual. ). Meanwhile, make sure that the signal line (PPM) of the Type-C cable connects to the PPM signal line of the audio port. If the connection is not established, the transmitter will not be able to correctly identify the PPM signal output from the headset, and will not control the headset.
Type-C Wire Sequence Type-C wire sequence definition: Noble NB4+ transmitter base Type-C interface uses GND, USB_DM (D- pins) , where the D- pin is used to transmit and receive PPM signals.
2. Before enabling this function, you need to select Trainer Mode by choosing [System] >[USB Setup]. 3. To enable the Trainer function, short press the power button of both transmitter bases to make sure that
