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 over the aircraft and constant information on its current status. Uncorrected 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 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. 2 2.2 Transmitter Overview VR1 Lanyard Eye TR3 TR4 SW1 Battery Speaker SW2 SW3 3 Speaker Trigger spring adjsustment Trigger size adjustment 4 VR1 Lanyard Eye TR3 TR4 SW1 Grip Battery Port USB Port (Charging) Power Button USB Port (Power Out) Screen RGB LED Power Button Trigger Position Adjustment Screw Wheel Tension Adjustment Screw Adjustable Arm TH Trim ST Trim Wheel 5 2.3 Receiver Overview SERVO SENS Status Indicator BIND 2.3.1 Status Indicator The status indicator is used to indicate the power and working status of the receiver.

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 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. icon. The icon will change to when active. 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 Go: Sets how quickly the throttle applies acceleration. Return: Sets how quickly the throttle backs off. 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:

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.
