10. Starting up the transmitter 10.1 Switching on the transmitter For testing purposes, switch the transmitter on using the On/Off switch (see Figure 2, Number 7). The display is made visible by the backlighting now. To save battery capacity, the backlighting is automatically dimmed after a while. The backlighting can be activated again by touching the display. Brightness settings and setting of the time until dimming of the backlighting are explained in chapter “Settings in the Main Menu / System”.
Middle position of the drive function Using the trimming button (TR3) for the drive function, set the middle position for the gas servo (TH). To do this, press the trimming button (TR3) either to the left or to the right in order to set the value to 0. If you hold down the trimming button, the value will be changed constantly. The value can be adjusted between left and right at up to 120 steps each.
11. Starting up the receiver 11.1 Receiver connection The receiver offers connection options for up to four servos (CH1, CH2, CH3, CH4) and a receiver battery pack (BIND/VCC). Figure 5a shows a connection chart for a model with external receiver power supply (figure 5a, item 1), as it is common, e.g, for a combustion model.
Example of the connection of a combustion models Figure 5 a Example of the connection of an electric model with an electronic cruise control and BEC switching Figure 5 b 14
11.2 Installing the receiver The installation of the receiver differs according to the model. For this reason, observe the recommendations made by the model manufacturer with regard to installation. Generally speaking, you should always try to install the receiver in such a way that it is optimally protected from dust, dirt, damp and vibrations. Double-sided adhesive foam or rubber rings are suitable for securing the foam wrapped receiver firmly in place.
11.4 Binding function In order for the transmitter and the receiver to communicate with each other, they must be bound using the same digital coding. When delivered, the transmitter and receiver are already coordinated and can be used immediately. The renewal of the Binding function is, primarily, only necessary after switching a transmitter or receiver or when eliminating faults. The transmitter and receiver are not bound if the LED in the receiver only flashes in spite of the transmitter being on.
12. Connecting a rotation sensor 12.1 Programming the Remote Control Three sensors are included in the delivery of the remote control that can record a temperature, a voltage and a speed. Up to 15 sensors can be connected to the receiver in series and displayed in different constellations in the transmitter. 12.2 Temperature sensor The temperature sensor “CTM01” can measure, e.g., the temperature of a speed battery in the range of -40 °C to +250 °C and transmit it to the transmitter by telemetrics.
12.5 Sensor Connections Plug the cable of the desired sensor (1) into the “SENS” socket at the receiver (2). Install the sensor just connected in your model according to its purpose (e.g. measuring temperature of a rechargeable battery) so that no cables can get into rotating parts of the drive. SENS After taken the transmitter and then the receiver into operation, the LED in the sensors lights up in addition to the LED in the receiver. Measurement and transmission to the transmitter is activated.
13. Checking the steering and drive function In order to ensure that the model does not drive off when you are checking the steering and drive function, place the model chassis on a suitable base (block of wood or similar). The wheels should be able to turn freely. 13.1 Checking the steering function Always carry out digital trimming before checking the steering function. For more information, consult the section “Starting up the transmitter” in the Chapter “Checking and setting the digital trimming”.
13.2 Checking the drive function Always carry out digital trimming before checking the drive function. For more information, consult the section “Starting up the transmitter” in the Chapter “Checking and setting the digital trimming”. When you pull the accelerator/brake lever for the drive function as far as possible in the direction of the handle, the model should accelerate. When you push the accelerator/brake lever for the drive function forwards, the model should be braked or switched to reverse.
14. Programming the remote control 14.1 Programming the remote control This product enables you to coordinate the drive, steering and switching functions of your model individually and to permanently store the set values. Only a model set to suit the given driver will offer the most fun. Information is entered into the product via the touchscreen display. As soon as you switch on the product, the following information will be shown on the LC display.
14.2 Symbol explanation Main menu This symbol is used to access the main menu. Here you can programme your product individually according to model. Back This symbol takes you back to the previous menu. Activate/Deactivate This symbols are used to activate or deactivate your individual settings. Reset This symbol is used to reset the individual adapted menu option back to the factory settings. Help This symbol is used to call the Help function (Help function in English!).
15. Main menu settings 15.1 Main menu settings Switch the transmitter on and select the main menu.
“Boat mode”: Boat mode “Brake mixing”: Brake mixer “Mixes”: Channel mixer “Display servos”: Display for position of all servo levers “Race timer”: Timer “Keys function”: Assignment of functions for trim buttons “Models” Model management „S.V.C.“: „Smart vehicle control“ (special receiver with integrated gyro system is needed; available as an accessory) “RX setup”: Settings for the receiver „Spectrum analyzer“: Radio channel monitoring “System”: Settings for the transmitter 15.
15.3 “End points” function Figure 13 This function can be used to specify how big the maximum permitted end point to each side for the steering, accelerator or additional servo may be. This function is generally used to protect the servos from mechanical stops when applying end points in full. You can set a value between 0 - 120 %. The smaller the value, the smaller the servo path on the relevant side. After calling the function „End Points“, you need to select a control element of the transmitter (e.g.
15.4 “Subtrims” function Figure 14 This function enables you to make an individual setting for the middle position of the drive and steering servos. A slight pull of the model to the left can be equalised/corrected with the help of trimming. This ensures correct straight forwards steering when the control wheel on the transmitter is in the middle position. Select the parameter to be changed to do this. Slide the regulator to the right or left to change the value to suit your requirements.
15.5 “Steering exponential” function This function enables you to influence the sensitivity of the steering. In doing so, the linear path between the controller and the servo is modified to a non-linear (exponential) path. A more sensitive control about the neutral position is thus possible. The maximum control path is not modified when doing this. “Exp.”: The value that can be set is -100% to 100%, whereby the value 0% corresponds to linear control.
15.7 “Steering mix” function The steering type “Standard“ is chosen in the basic setting; no further settings are possible. Select the steering mode “Crawler mode“ to be able to make the following settings as also shown in figure 17. “Front side”: Only the steering servo for front wheel steering, connected to CH1 at the receiver, will be activated. “Rear side”: Only the steering servo for rear wheel steering, connected to CH3 at the receiver, will be activated.
15.8 “Throttle neutral” function This function allows you to specify the behaviour of the accelerator/ brake lever close to the neutral position. “Forward”: This defines the point at which the model starts to accelerate when the accelerate/brake lever is operated. “Dead zone”: This is used to define the magnitude of the neutral position in which the accelerator/brake lever does not cause a reaction.
15.9 “Throttle exponential” function This function enables you to influence the sensitivity of the accelerator/brake servo. In doing so, the linear path between the controller and the servo is modified to a non-linear (exponential) path. A more sensitive control about the neutral position is thus possible. The maximum control path is not modified when doing this. “Exp.”: The value that can be set for this function is -100 % to 100 %, whereby the value 0 % corresponds to linear control.
15.11 “A.B.S.” function Figure 21 This function enables you to prevent blocking of the wheels when braking by means of automatic pulsing (opening and closing of brakes). This enables you to maintain control of the model even when braking heavily. “Brake return”: Here you specify to what extent the brake is opened for each impulse. At 100%, the brake opens fully and the brake servo returns to the neutral position after each impulse. A value of 0%, on the other hand, deactivates the “A.B.S. function”.
A well-working A.B.S.-brake always requires a sufficiently strong and also fast throttle servo for a combustion engine model. If you programme the A.B.S. brake in an electronic speed controller, the higher dynamics of the electronics generally require that lower brake values are set. The A.B.S. brake loads the speed controller and motor thermally as well. The power consumption rises as well and additionally discharges the drive battery. “Steering mix”: Here, you can couple the activation of the “A.B.S.
15.13 “Throttle middle position” function This function permits changing the servo adjustment path starting in the neutral position of the throttle lever. The example shown in figure 23 would move the throttle servo (or the electronic speed controller) by 60% of the servo control path if the throttle lever at the transmitter is moved from the neutral position towards full throttle.
15.15 “Engine cut” function This function is used to ignore the position of the accelerator/brake lever of the remote control and set the accelerator/brake servo to a predefined position. A chosen switch (e.g. SW1 to SW3) must be assigned to the “Engine cut” function. This is done in the “Keys Function”. Push the switch programmed for “Engine cut”. Push the controller to the right or left to adjust the value to your wishes.
15.17 “Brake mixing” function This function enables you to control the brakes using two or three independent servos. The Channels 3 (CH3) or 4 (CH4) are used as slave channels for the accelerator/brake servo, whereby only the braking function has an influence on the slave channels. After activating one of the two channels, you can set the A.B.S. as well as the exponential function of the accelerator/brake servo for this channel individually.
Figure 22 “Master channel”: Here, you select the Master channel. “Slave channel”: Here, you select the Slave channel. “Low side mix”: The influence of the “Left servo control device” of the master channel on the slave channel is determined. If you set 0% or a positive percentage, the slave channel is not triggered when the “High side mix” is deactivated. The settings for “Low side mix” and “High side mix” influence each other with the “High side mix” activated.
15.19 “Display servos” function This function shows you real-time information regarding the position of all four servo levers. For this, move the control elements of the transmitter (e.g. the steering wheel). Click the icon “Servo lever” next to the green “Return arrow” to activate a “Servo tester”. All the connected servos for the set values (end points, rotating directions, etc.) are moved automatically. The display for this is according to the movement of the servos at the display. Figure 30 15.
The timer continues to operate even when the set time has been counted down. In this case, the product automatically switches into “Up timer” mode. In this case, a short signal sounds after the end of the set time if the sound is activated (see menu item “Systems”). Times between 1 minute and 99 minutes can be set. “Lap timer”: This mode allows you save a specific lap time. Tap the “Start” button to start timing. Then, tap the “Lap” button to save a lap time. To stop timing, tap the “Reset” button.
15.22 “Models” function This function permits naming up to 20 different models and saving them with all the programmed inputs. You can, e.g., programme and save one and the same model several times with different setups (e.g. “Setup dry” or “Setup wet”). Up to 13 characters can be used for the model name. Spaces count as characters for this as well. “Select model”: Select the required model from the list. Tap the “Back” button to activate the selected model and return to the previous menu.
15.23 “S.V.C.” function The function “S.V.C.” (= “Smart vehicle control”) can be activated when using a receiver with integrated gyro system (not enclosed, can be delivered as an accessory) and set individually. Depending on setting, the movement of the model in driving operation is dampened (vehicle will skid less) or increased (vehicle will skid more). The function “S.V.C.
15.24 “RX setup” function This function enables you to programme the receiver. The following setting options are available for use: “Bind with a receiver”: Select this function if the transmitter is to be bound to a receiver again. “RF std.”: The communication protocol between the transmitter and receiver is specified here. Use “AFHDS 2A 1-way” (without telemetry) or “AFHDS 2A 2-way” (with telemetry) for the receiver type from the remote control set.
“Failsafe”: This function permits programming of the servo items that are automatically set when the receiver signal is lost. When the settings are set to “Off”, the servos remain in their last position when the signal is lost. This is how you change the values of the individual servo positions: Activate “Steering”: Tap the “Activate/Deactivate” button. Turn the control wheel for the steering function to the left or right and hold the desired position.
“Range test”: If you select this function, the lower part of the display will show the current signal strength with a value of 1 to 10 and the receiving field strength (“RSSI”) at regular transmission output. If you were to move away from the model now, these displays would remain stable for a long time in the near distance due to the full transmission output. To perform a range test in the near distance, you can reduce the transmission output with a button.
Proceed as follows to update the receiver firmware: Switch off the transmitter and the receiver. Plug the programming plug into the “BIND” socket of the receiver. First switch on the receiver system and then the transmitter. At the transmitter, call the “RX setup” menu, and there the submenu “Bind with a receiver”. Then leave the submenu again. The display will show “Update Receiver”. Confirm this with “YES”. The display will change to a percentage display and thus show the progress of the update process.
15.26 “System” function This menu allows you to make various settings for your product. “Backlight timeout”: Here you set the length of time for the backlighting of the LC display when it is no longer being touched. “Backlight”: Here, you can set the brightness of the backlight for the LC display. A higher value ensures better recognition of the LC display but also causes faster discharge of the battery pack. “System sound”: Checking this check box will activate all sound effects (e.g.
“Language”: Here you can set the menu language of the product. English, French and Chinese may be set. At the moment, only English can be set. “Themes”: Under “Themes”, you can choose between three different display versions. Here, the background design of the display as well as the graphics of the tiles of the individual functions is changed. “Firmware Update”: Here, you can perform a firmware update.
15.27 “Warning Signals” function Acoustic Warning Signals A number of acoustic warnings are installed in the remote control. The acoustic warning can, however, only be performed when “Sound” is activated in the submenu of the same name in the menu “System”. The following warning signals are present: • If the battery voltage at the transmitter drops below 3.75 Volt, a howling sound occurs.
16. Maintenance and care The product is maintenance free. Do not disassemble. From the outside, the remote control should only be cleaned with a soft, dry cloth or brush. Never use aggressive cleaning agents or chemical solutions otherwise the surfaces of the housing may be damaged. When cleaning, do not put too much pressure on the LC touchscreen display. 17.
