6FS-lT4SDigital proportional radio control system2. Introduction The FS-iT4S is an 8-channel 2.4GHz AFHDS 2A digital proportional R/C system. It is compatible with cars and boats.2.1 System FeaturesThe AFHDS 2A (Automatic Frequency Hopping Digital System Second Generation) developed and patented by FLYSKY is specially developed for all radio control models. Offering superior protection against interference while maintaining lower power consumption and high reliable receiver sensitivity, FLYSKY's AFHDS technology is considered to be one of the leaders in the RC market today.Bidirectional CommunicationCapable of sending and receiving data, each transmitter is capable of receiving data from temperature, altitude and many other types of sensors, servo calibration and i-BUS Support.Multi-channel Hopping FrequencyThis systems bandwidth ranges from 2.4055GHz to 2.475GHz. 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. Omni-directional Gain AntennaThe high efficiency Omni-directional high gain antenna cuts down on interference, while using less power and maintaining a strong reliable connection.Unique ID Recognition SystemEach 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 ConsumptionThe 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.

Navagate functions by swiping up and down to navagate lists and press an item on the list to select it. □To go back to a previous menu press the Icon.
14FS-lT4SDigital proportional radio control system6 Reverse FunctionThe Reverse function is used to correct a servo or motor's direction in relation to the systems controls. For example if a servo is mounted upside down in order to fit inside a model (in this case steering), when the systems steering wheel is turned the servo will move in the oppisite direction. To fix this all we need to do is reverse CH1. □To reverse a channel, touch the channel in the list, when reversed the slider will be at the "REV". □To reset the function to the default setting touch the icon. □To return to the main menu touch the icon.6.1 End Points FunctionEnd points are the limits of the servos range of movement. There are 2 endpoints per channel, one is the low endpoint and one is the high end point. To select an endpoint move the desired control surface in the direction you wish to change. The currently selected endpoint will be highlighted in yellow. Once you have choosen an endpoint, touch the channel you wish to change. At the top the current channel, selected endpoint and percentage are shown. The endpoints location is also shown as a bar and needleTo edit an endpoint's value drag the wheel at the bottom of the screen. Left to reduce the value and right to increase the value.6.2 Subtrim Function Subtrim changes the center point of the channel, for example if a car's wheels are slightly out of alignment the sub trim could be used to fix this. To set the subtrim function:1. Select the desired channel from the list. 2. Use the wheel at the bottom of the screen to change the value, a real time readout of the channels position can be seen in this menu as a green bar.3. Select the back icon to return to the previous menu and save. The sub trim has a value representing the current subtrim setting, followed by a graphic representation of the current trim position. Below the graphic there is a real time read out of the channels current position.
15The method for changing settings in this function is the wheel located above the menu bar at the bottom. □To restore default settings of a single channel, select the reset icon within its subtrim menu. □To restore the entire function to default, select the reset icon in the channel selection menu.Channel List Subtrim setting and channel's current position6.2 Steering Exponential This function changes the response curve of the steering, there are 2 main parameters: □Rate: Changes the outer limits of the steering, the default is 100%. Rate cannot be more than 100%. □Exp.: Changes the steering curve, which changes he response of the steering wheel, the exp setting can be positive or negative. (Exponential)Changes to the rate and exponential can be seen on the graph located in the center of the screen, the system also gives a real-time readout of the channels current position.Changes to the rate and exponential can be seen on the graph, located in the center of the screen. The system also gives a real-time readout of the channels current position.Note: The system gives a real time readout of the channels position, not the wheels position. The wheel will not correlate with the graph if the rate is under 100% ,or another function like trim has made changes to the channels movement and/or outer.By changing the steering curve we can make the wheel more or less sensitive in at different areas of its range of movement, for example, reducing sensitivity at the middle for more control when making fine adjustments. This function must be set as active before use, to activate the function make sure that the icon in the bottom left corner is showing a tick, if there is no tick then press the icon to enable. Exponential 100%
16FS-lT4SDigital proportional radio control systemTo set the steering exponential/rate:1. Select the desired parameter, rate or exp.2. Use the wheel at the bottom of the screen to change the value. To restore the entire function to default, select the reset icon located at the bottom center of the screen.This function can be toggled using a switch/button, this is assigned in the [Keys function]. To restore the entire function to default, select the reset icon located at the bottom center of the screen.Exponential 0% Rate 64%6.3 Steering SpeedThis function changes the speed in which the steering travels, if the cars wheels are turning too fast, it could lead to loss of control, on the other hand if they don’t change position fast enough the car will become sluggish and slow to make turns. This function is also used to simulate a realistic for scale models. There are two variables:Turn Speed: Sets how quickly the wheels turn from their starting position, to the position the systems controls indicates.Return Speed: Sets how quickly the wheels turn back to their center position. To set the steering speed:1. Select a parameter to change.2. Use the wheel at the bottom of the screen to change the value. To restore the entire function to default, select the reset icon located at the bottom center of the screen.6.4 Steering MixThis function changes which wheels are involved in steering, front, rear, or 4 wheel steering. To enable this function select “crawler mode” from the functions main menu.
17There are 4 types of steering control: □Font side: Front wheel steering. (Default) □Rear side: Rear wheel steering. □Same phase: Front and rear steering at the same time, when turning a direction all the wheels will turn the same direction. □Rev. phase (Reverse Phase): The front wheels and back wheels are both involved in the turning process however, the rear wheels will always turn the opposite direction to the front wheels. To set the steering mix: Select the desired method of steering, the system shows a preview of the steering method on the screen in real-time when moving the system wheel.To reset this function, select the reset icon located at the bottom middle of the screen. 6.5 Throttle NeutralThis function can set a “dead zone” for their throttle control, this means that the throttle will not function while still within the dead zone. It is also possible to set up the initial amount of throttle that will be applied when the throttle leaves the dead zone, although this can only be set for driving forward, not in reverse. To set the throttle neutral: □Dead zone To setup the dead zone select the dead zone option at the left side of the screen, and use the wheel at the bottom of the screen to change the value. The current percentage will be shown above the graph, labeled as dead zone. □Forward First select [Forward], next move the wheel to set its value.Once finished setting up these functions, press the back icon located at the bottom right of the screen to save.
18FS-lT4SDigital proportional radio control system6.6 Throttle ExponentialThis function has two variables: □Rate: Reducing the rate shrinks the outer limits of the curve, as the rate drops below 100% the graph will update in real-time. The maximum is 100%. □Exp. (Exponential): Exponential adds curve, it is possible to move to +-100% creating opposite curves. To reset this function select the standard steering mix from the functions main menu. This function can be toggled using a switch/button, this is assigned in the "Keys function".6.7 Throttle CurveThis function is used to add a curve to the throttle response, meaning that the throttle will respond differently throughout its range of movement. This function must be activated and can be assigned to a button (See "Keys Function"). To activate this function press the icon located at the bottom left of the screen, once activated this icon should show a tick. This function has 5 points that can be edited. To select a point simply touch the corresponding number (L is the lowest point and H is the highest point).Once a point is selected use the wheel at the bottom of the screen to change its value, all changes will be shown in real-time on the graph, if the trigger is moved the graph will show the current throttle position. To reset this function press the reset icon located at the middle bottom of the screen.
196.8 A.B.S.A.B.S. stands for auto breaking system, and is designed 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, this is done by pumping the breaks on and off rather than a constant force. This function must be active to work, if the icon at the bottom left corner is not showing a tick, select it. When a tick is shown the function is active. As a square wave, the peaks representing break on ,and the drops break reduction. Trigger point: Changes the point in which the A.B.S. will kick in. The trigger point is represented as a white line on the graph. To change the position of the trigger point use the wheel at the bottom of the screen. Break returnControls the amount the break will back off from full break, if set to 50 percent then when the breaks are active, the pulse will remove 50 percent of the breaks strength on each pulse. Here the pulses are shown as a square wave, the peaks being break on, and drops being reduction in breaking. As the break return function is edited the square wave will change to represent the current return value. To edit this function simply use the wheel to change its value, as the value is changed the graph will show a new wave form in real time. To test apply the brakes, the graph should show another red waveform representing the current real-time effect. Below the graph is a bar that shows the breaking position in real time, when this function is active and the break is applied the green bar will bounce, this is normal and is just showing the A.B.S. in action. DelayThis 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 break is applied, however the higher the percentage the longer it will take for the A.B.S. to kick in. Cycle lengthIncreases or decreases the time between pulses, in this menu the A.B.S. function will be shown as a square wave, the peaks representing break on , and the drops break reduction.
20FS-lT4SDigital proportional radio control systemTrigger pointChanges the point in which the A.B.S. will kick in. The trigger point is represented as a white line on the graph. To change the position of the trigger point use the wheel at the bottom of the screen. The higher the percentage the more the trigger has to be moved in order for the A.B.S. to kick in.Duty cycleChanges the length of each pulse and the gap between them, as the wheel at the bottom is moved it will change the breaking from a symmetrical wave form, to a wave form with longer dips or longer peaks. Changes to the wave form are shown in real time on the graph. Steering mixWhen turning A.B.S. can become a problem for some models, this function mixes breaking and steering, so that when the car makes a turn the A.B.S. will be turned off and replaced with a constant breaking pressure, this will be shown as %N. To have constant breaking unless turning simply move the wheel the opposite direction so that the header shows %E. To change this function simply use the wheel to take it from it’s off position, and apply a percentage of breaking force. The graph will show the results real-time, also when the trigger is moved the results will be show on the graph.
216.9 Throttle SpeedThis function changes how quickly the throttle will react, both when pressed and released. This is useful to emulate different models such as big trucks, which in real life take longer to get up to speed and slow down.There are 2 main settings in this function: □Go: How quickly the throttle applies acceleration. □Return: How quickly the throttle backs off. To adjust these settings, select the desired setting and use the wheel to change its value, 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 throttles current position in real time. When the bar is red it is showing the triggers position on the throttle position, when the function is active the red line will move first, followed by the green line as it catches up with the trigger position.
22FS-lT4SDigital proportional radio control system7 Throttle MiddleThis function changes the midpoint of the throttle, this could be used in a middle in which the servo and the throttle position do not line up with no throttle, if this is the case the model may move as soon as it’s turned on. To change the midpoint, use the wheel at the bottom of the screen, the current position will be shown on the screen in real time. 7.1 Throttle Idel UpThis function is used for models that use a fuel based engine, if left at 0 throttle these engines will stall. To combat this idle up makes sure that the engine always has some throttle in order to keep it from stalling. When finished using this mode, you can press the assigned button to bring the throttle to 0, effectively cutting the engine although this is usually done using the engine cut function. This function must be assigned to a switch/button in order to be activated (see keys function). To set this function first assigned it to a switch/button, once the button is pressed the icon in the bottom left corner of the screen (within the function) should become a tick. Then use the wheel at the bottom of the screen to change the value. 7.2 Engine CutThrottle cut is used for fuel based models and is used to cut the throttle, essentially cutting the engine. To edit the settings move the wheel at the bottom of the screen. When active the function will stop the throttle droping below the defined point. For help setting up your model's engine consult the model's user manual. This function must be assigned to a switch/button to be activated.
237.3 Boat ModeThis function is used only when you are using a model boat. When using this function the break functionality is disabled and the throttle channel is set to its lowest position.To toggle this function select the box beside "Normal mode", when the function is active the text beside the box will change to "Boat mode".To toggle this function select the box beside "Normal mode", when the function is active the text beside the box will change to "Boat mode".7.4 Break MixingThis function enables you to use models that require more than one braking channel, for example a model that has separate brakes for from and back breaking. If your model uses extra channels for braking, each channel can be controlled separately and are slaves of the throttle channel. (Exponential and A.B.S. functions are the same as earlier discussed)7.5 MixesThis function is used to create a mix between channels and control methods. For example if at lower throttle some automated flap movement was desired then it is possible to create a mix to do this. The difference between curve mixes and linear mixes is that it is not possible to create a nonlinear relationship between the master and slave. It is possible to have up to 4 mixes.1. After selected a mix, select the bottom left icon to ensure there is a tick in the box, next select the "master", this channel/input will be designate the slaves output. It is possible to select stick/knob, basic functions or a channel output. 2. Next select a slave. A slaves may only be output channels, however this also includes any unused aux channels. Once you have you slave selected you can apply a curve to the mix, to do this select either the low side or high side as desired and use the wheel to change the value, it is also possible to offset the channel in relation to the master using the offset option. Each curve mix can independently be signed to a toggle using the icon.
24FS-lT4SDigital proportional radio control system7.6 Display ServosThis function displays the models channel output and can be used to test output and servo range, the test button at the middle bottom of the screen will cause the channels to move slowly though their entire range. To toggle this function press the icon at the bottom center of the screen. WARNINGIf the model engine is powered on while the test function is activated will rev up.7.7 Race TimerThe race timer has 4 modes: □Up timer: Counts up. □Down timer: Counts down from the set time. □Lap timer: Keeps track time for each individual lap. □Lap memory: Records the results from the lap timer.To start the timer touch the "Start" icon and to stop select the "Stop" icon. To reset press the rest icon.
257.8 Keys FunctionThis function assigns the systems physical buttons to different functions. To assign a function to a key select the key from the diagram, then select a function from the list. WARNINGIf the model engine is powered on while the test function is activated will rev up.To set the keys function:1. Touch one of the trim or switches shown on the diagram.2. Scroll down the list until you find the function you wish to assign and select it.3. Once the selection has been made the function will automatically return to the previous menu. 7.9 ModelsThe models function is used to change between, copy and delete model setups. The FS-iT4S can store up to 20 different models in the internal memory.Selecting a model:To select a model touch the select model menu, once in the menu touch the name of the model to load it.

278.0 RX Setup8.1 Bind with a receiverThis function enables you to bind the RX and TX so that no other system may interfere with your models operation. To bind the transmitter with a receiver:1. Connect the bind cable to the RX, then connect the power.2. On the TX select “Bind with a receiver”.3. Once the RX and TX are bound the TX will exit this menu automatically (Unless using a 1-way communication protocol such as AFHDS 2A 1-way in which case you must exit this menu manually). 8.2 RF std.: ADHDS 2A 2-wayThis menu allows you to change the communication protocol for the TX, the available protocols are: □AFHDS □AFHDS 2 □AFHDS 2A 1-Way □AFHDS 2A 2-WayNoteAFHDS 2A 2-Way is the latest, most stable and advanced communication protocol. When changing mode you will be prompted to confirm.8.3 Receiver PPM Output When checked, the receiver only outputs PPM on CH1 output, however PPM is capable of transferring all channels even though there is only one physical output (When enabled the other 9 outputs are disabled). To enable PPM touch the box in this menu. When the box is checked the PPM is active.
28FS-lT4SDigital proportional radio control system8.4 RX Battery MonitorMonitors the receiver battery voltage. Use the supplied battery’s user manual to set the lower and higher voltages, so that the system can monitor battery level effectively. Setting the voltage alarm sets a custom low battery level alarm.To change settings, touch the desired value and move the wheel to set the new value. □External sensor: This option enables monitoring battery status using an external sensor. □Low voltage: This sets your batteries default low voltage value is 4.00V. □Alarm voltage: Sets the low voltage alarm. □High voltage: Set the maximum voltage when the battery is full. The default high voltage is 5.00V (Check your battery specifications). 8.5 Low Signal Alarm When checked, an alam will be triggered if the receiver's packet error rate rises above 60%. 8.6 FailSafeThis function is used to protect models and users if the receiver loses signal and therefor is no longer controllable. All 4 channels are listed in the failsafe menu, "off" means that in case of a loss of signal, the corresponding servo will keep its last received position, if it displays a percentage the servo will instead move to the selected position.To set a failsafe position select a channel and select the icon at the bottom left of the screen, if it has a tick, it is active. To set the value, move your channel to the desired position, for example to cut the throttle when signal is lost enter the throttle channel and move the stick to the bottom (-100%), then exit back to the failsafe channel list. Once the failsafe has been set the value will show up in the failsafe channel list instead of being listed as "off".8.7 Display SensorsThis function displays current active sensors.The type of sensor is displayed on the left hand side, its ID in the middle and the sensors output on the right. Under “Type”, and the sensors output on the right under “Value”. All sensors have numerical ID shown in the middle column.At the bottom of the list this menu has an error rate display, this is a good indicator of signal quality.
298.8 Choose SensorsThe main screen can display the value of up to 4 sensors, this function selects which sensors are displayed. First select a slot, any sensors that are connected will automatically populate this list, select the desired sensor and exit the function.There are 2 types of sensors, basic and advanced. A basic sensors only reports back 1 value, but an advanced sensor is able to monitor several things at once, for example altitude, temperature and speed.8.9 Speed and DistanceThis function allows the user to monitor the models RPM and how far it has traveled. If the sensor appears in the menu, it means that there is one connected. □Speed sensor Selects the desired sensor. □Set rotation lengt When attaching a speed sensor to a wheel etc, it is important that the sensor knows exactly how far out from the sensor it is. The system uses this distance to calculate distance traveled. □Odometer 1 Records the distance traveled during a session. (Note: Restarting the system will also reset odometer 1) □Odometer 2 Records the total distance traveled since last reset. This means that the distance over several sessions will be added together. Reset odometer 1: Resets odometer 1 to 0.Reset odometer 2: Resets odometer 2 to 0.
