Digital proportional radio control system FS-lT4S 6 Reverse Function The 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.
The 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 position 6.
Digital proportional radio control system FS-lT4S To 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.
There 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.
Digital proportional radio control system FS-lT4S 6.6 Throttle Exponential This 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.
6.8 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.
Digital proportional radio control system FS-lT4S 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. The higher the percentage the more the trigger has to be moved in order for the A.B.S. to kick in.
6.9 Throttle Speed This 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.
Digital proportional radio control system FS-lT4S 7 Throttle Middle This 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.
7.3 Boat Mode This 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".
