To install a module proceed as follows: 1 Switch off the transmitter. 2 Disconnect the headset and USB cables. 3 Open the transmitter.
Transmitter 3.4 Transmitter battery The PROFI TX is powered by a very robust and durable LiFePO4 battery. The battery is installed with the electronic system for battery management in a welded case. If the battery is new, the battery capacity of 4000mAh provides an uptime of more than 25 hours. Additionally installed components increase power consumption and shorten the operating time. If the device is exposed to very low temperatures, the operating time is significantly reduced. 3.4.
Transmitter 3.4.1.1 Charging the battery via the PC Proceed as follows: 1. Switch off the PROFI TX. 2. Lift the device. The recessed control for the sliding latch is located on the underside of the case. 3. Slide the sliding latch towards the device centre. 4. Switch on the PC or laptop. Connect the supplied USB cable to a USB socket on the PC and to the mini USB socket on the PROFI TX. o The PROFI TX starts automatically in charging mode.
Transmitter 3.4.1.2 Charging the battery using the plug-in charger Proceed as follows: 1. Lift the device (the recessed control for the sliding latch is located on the underside of the case). 2. Slide the sliding latch towards the device centre. 3. Connect the supplied USB cable to the plug-in charger and to the mini USB socket on the PROFI TX. 4. Connect the plug-in charger to a mains outlet.
Transmitter 3.4.4 Battery management The PROFI TX records the current during transmitter operation and while loading the transmitter battery. The available battery charge is calculated on the basis of the power meter reading, the temperature and the voltage. The remaining operating time (time to empty) is calculated from charge and current and is shown on status display #2 (see page 87). The calculation takes into account that current consumption slightly decreases with decreasing battery voltage.
Transmitter 3.5 Switching the transmitter on / off Charge the transmitter battery! The PROFI TX is supplied with a partially charged transmitter battery. You should charge the battery prior to setup. Observe the notes on charging (see section 3.4 "Transmitter battery" on page 41). 3.5.1 Switching on To switch on the device proceed as follows: 1. Press and hold the Power button until the annular light is fully lit. The device is switched on when you release the button.
Transmitter Switching on in Binding mode Press and hold the ¡ button until the status display is shown (see section "Binding" on page 48). Switching on for range check Press and hold the § button until the status display is shown. The device starts up with reduced transmitting power when the range check is performed (see section 3.6 "Range check" on page 47). Switching on for the first time The very first time you switch on the PROFI TX is a special case.
Transmitter 3.6 Range check Regular range checks are necessary for ensuring the reliable functioning of the radio control system and for timely detection of changes in transmission properties. Always perform a range check after: installing, modifying or rearranging components in the model, reusing components in the model that were involved in a crash, irregularities when operating the model.
Transmitter Procedure 1. If the model is fitted with a power system, switch it off! 2. Press and hold the ¡ button on the transmitter as you switch the transmitter on. 3. Switch on the receiver. 4. In the Servo > Test run menu, activate the test run for a control function, e.g. Elevator. This allows you to check that the receiving system responds to control commands with distinct, regular movements of the control surfaces. 5. Increase the distance between transmitter and model.
Transmitter For "spread spectrum", every data bit is coded in 64 bits (spread). This procedure provides a high level of interference resistance. During binding, the transmitter passes "hopping sequence“, "spreading code", and "response time" to the receiver. Procedure 1. Press and hold the tool button and switch the transmitter on. Once activated, the safety check display is shown. Follow the instructions shown. o The (flashing) message "BINDING" is shown in the status displays #2 to #8.
Transmitter 3.7 Trainer mode The trainer mode (teacher / student) is the safest method for beginners to get started in model sport. An experienced model pilot has control over the model as the teacher. The trainer can transfer control functions to the student by operating a button. Initially these will be individual control functions, and later all the main control functions. The PROFI TX can be configured either as a teacher transmitter or as a student transmitter.
Transmitter 3.8 Digital trim 3.8.1 Overview "Trimming" refers to the adjustment of the model aircraft to fly straight and level when you leave the sticks exactly at centre. Digital trim has two essential advantages: The physical position of a conventional trim with trim slider corresponds to the actual trim value, while digital trim buttons do not. The digital trim position is displayed on the screen, and any change to the trim values is stored in the model memory.
Transmitter about 0.8 sec., the trim value changes continuously until you release the button again (AUTO-REPEAT function). When the trim reaches centre, the AUTOREPEAT function stops briefly. Each trim increment is accompanied by an acoustic signal. On reaching the trim centre and on reaching the maximum trim range, specific acoustic signals are emitted to alert the user. The volume of the acoustic signals during trimming can be configured in the Setup > Transmitter > Volume menu (see section 5.3.

Locked flight phases are shown crossed out. x Identifies the active flight phase. Switch (e.g.
Menus 5.3.3 Training (principle) In trainer mode (teacher / student), a wireless connection is established between two Multiplex transmitters via M-LINK. The teacher transmitter controls the model and must be bound to the model (Binding). The student transmitter transfers the stick signal to the teacher transmitter via M-LINK. The teacher can transfer a freely definable group of control signals to the student. The teacher transmitter requires a receiving device for the student signal.
Menus The message STUDENT MODE flashes on the status displays #2 to #8 while the Student mode is active. Both transmitters must use the same Format setting; otherwise, the centre positions of the control signals will differ. Remember to set "Training" to OFF if you wish to control the model directly. 5.3.3.2 Teacher mode For Teacher mode, a COPILOT module and an assigned switch are required (see section 3.7 "Trainer mode" on page 50). Set "Training" to ON. This activates the training system.
Menus o The servo channel used by the student transmitter for transmitting the elevator signal is displayed next to Elevator, usually Ch2. o Check on the model if the rotation direction of the student signal is correct. You can reverse the direction by pressing the REV/CLR button. Make sure that the model motor cannot start up! o Close the menu item. Repeat these steps to assign all control functions that the student is allowed to control.

Menus To assign a control function proceed as follows: o Open the desired input field. o Assign a control by pressing the + / – buttons, by using the central wheel or by operating the control. o To set the actuation direction keep the control in the desired zero position and close the input field. Alternatively, you can invert or erase the input by pressing the REV/CLR button, if required. 5.3.6 Assign.Switches You can use the Assign.
Menus down / up Upper or lower switching threshold, respectively ‡, E, F, G, H Sticks and sliders for which the thresholds are set. The arrow points to the side on which the control is installed: left (<) or right (>). To set a switching threshold proceed as follows: 1. Select the desired control. 2. Open the down switching threshold. 3. Adjust the value by pressing the + or – buttons or using the central wheel. 4. Open the up switching threshold. 5. Adjust the value.
Menus 5.3.6.2 MagicSwitch You can use the MagicSwitch sub-menu to change the configuration and settings for the two MagicSwitches MS1 and MS2 (see section "MagicSwitch" on page 173). The following settings are available for both MagicSwitches: Switch Switch assignment and combinations. ON delay, OFF delay Delay time for switching the MagicSwitch output; OFF and ON delay can be configured separately. To assign a MagicSwitch proceed as follows: 1. Open the desired input field. 2.
Menus 5.3.7 Define mixer You can use the Define mixer menu to define how the mixers on the servo side are construed. The parameters are configured in the Mixer menu (see section 5.5 "Mixer main menu" on page 126). The mixer definition determines the structural design of the mixer. Each mixer can combine up to eight control functions (mixer inputs). A switch can be assigned to every input. The mixer method is defined using options. The number of mixers depends on the model template selected.
Menus Control function You select the mixer input in the first field simply by operating the desired control function. Naturally, this only works if the control (actuator) has a control function assigned. Alternatively, you can use the + / – buttons or the central wheel to select a control function as mixer input. Switch In the second field the mixer input can be configured as switchable. To do this, simply operate the desired switch. Upon exiting the input field the switch position is ON.
Menus œ The neutral position is located on one side (end-point) of the control. The control travel is set at half and at full travel. 2 The input control function (usually aileron) changes direction upon each assignment of this mixer to a servo. Example: The aileron moves up on one wing panel and down on the other. This option can be combined with ™, + š and Cu. The icon represents the offset. An offset shifts the zero point of the mixer to one side. Example: The ailerons are raised as spoilers.
Menus Cu The input passes through a 7-point curve before mixing. You can choose from 8 curves. The same curve can be used for multiple inputs in different mixers. This eliminates extra configuration effort.
Menus 5.3.8 Transmitter You can use the Transmitter menu to configure transmitter-related settings such as audible signals, battery warning threshold, contrast, etc. The settings in this sub-menu only apply to the transmitter. They are not stored in the respective active model memory on the SD card, but in a dedicated memory area. Volume The volume of audible signals can be configured and switched off in groups. For system alarms, it is only possible to reduce the volume.
Menus Screen Screen settings: Contrast Optimise the contrast. Possible values: +8 to -8 Factory setting: 0 Trim graph Visualisation of the stick trim positions in the lower corners of the screen.

Upon entry of the correct PIN, all input fields remain unlocked until the device is switched off again. If the wrong PIN is entered the input fields remain locked. The PIN prompt is displayed every time you try to open an input field. Language Used for changing the menu language.
Menus 5.4 ControlFunctions main menu You can use this menu to adjust the settings for control functions, e.g. trims, travels, control curves, etc. The menu is dynamic: It lists only the control functions that are actually used, i.e. the control function must control at least one servo—either directly or indirectly using mixers. The menu content differs for vehicle models, fixed-wing models, and helicopter models.
Menus Opening the main menu To open the main menu: button Fixed-wing models: Helicopter models: PROFI TX Page 113
Menus The general screen layout is identical for all menus. This example shows the screen for the Aileron control function: Designation of control function and active flight phase At the top, the designation of the control function is shown followed by the name of the activated flight phase (in the example: NORMAL). Parameter list On the left, all parameters for the selected control function are listed with their set values.
Menus 5.4.1 Aileron, Elevator, Rudder The following control functions operate identically: Aileron, Elevator, and Rudder for fixed-wing models Aileron, Elevator, and Rudder for helicopter models Trim Current trim setting of the control in the respective flight phase (only display). Step size Trim increment: 0.5%, 1.5%, 2.5%, 3.5% Step size defines the trim change (in %) per trim increment (see section 3.8 "Digital trim" on page 51). For general-purpose use an increment size of 1.
Menus Travel Setting for the control travel (flight phase specific): 0% to 100% You can influence the control sensitivity of a control during a specific flight phase using the Travel parameter. That means you can configure a different value for each flight phase, e.g. in the flight phase NORMAL = 100% for maximum control surface effectiveness, in the flight phase SPEED1 = 60% for finer control.
Menus 5.4.2 Throttle (fixed-wing models, vehicles, boats, and funcopters) The Throttle control function provides the following functions for fixed-wing models: Throttle-Cut Throttle cut switch for the motor (only display) Trim Current trim setting of the control in the respective flight phase (only display). Step size Trim increment: 0.5%, 1.5%, 2.5%, see page 115. Mode Used for switching the trim from centre trim to idle trim and adjusting the idle height for models with internal-combustion engines.
Menus 5.4.3 Throttle (helicopter) The Throttle control function provides the following functions for the templates eHELI FBL, eHELIccpm, HELIccpm, and HELImech.: Governor Choose between throttle curve or controller with active Governor mode (speed controller). OFF The throttle curve is used. Individual curves are used for each flight phase. ON A controller with active Governor mode is used: Each flight phase has a fixed value. Governor OFF P1 to P7 7-point curve, flight phase specific: 0.0% to 100.
Menus Trim Display of the throttle trim value Lower limit Defines the lower limit for the throttle curve to ensure safe idle speed. This setting is overridden in the auto-rotation flight phase (AUTOROT). Not required for models with electric power system: Thus, set to 0%. The flight phase-dependent throttle trim is added to the lower limit and thus increases the lower limit by the trim value. The horizontal dotted line in the graph shows the position of the throttle limiter in all flight phases.
Menus Special case: auto-rotation In the AUTOROT flight phase the throttle curve is switched off. All curve points have the same value: You can set the throttle position for auto-rotation at every curve point. The lower limit is switched off. For training with an internal-combustion engine, set a value at which the motor does not yet stop.
Menus Go ve rno r ON fo r electric helico pte rs with brus hles s mo to rs in Go ve rno r mo de In Governor mode, the speed controller (governor) provides for a constant system speed. It merely requires a fixed value for the required system speed in the respective flight phase. The throttle curve can be switched off in the ControlFunctions > Throttle menu by choosing the setting Governor = ON. 5.4.4 Spoiler, Flap, Retract.
Menus Open the Controls > Flap menu item. To begin with, set estimated values for the Fixed value of the flight phases SPEED1 and THERMAL1. Retain the value OFF for the NORMAL flight phase. Allocate a digi-adjuster (see page 164). The allocation applies to all flight phases. Now, you can use the digi-adjuster to optimise the camber in flight from the status display. If OFF is selected, the digi-adjuster has no effect: The flaps are controlled by the assigned control.
Menus covers the entire setting range. the setting for the rotational speed around this axis. In neutral position the rotational speed is maintained at zero: The model always points in the same direction. The sensitivity setting ranges from The sensitivity setting ranges from 0% ... 100%: -100% ... +100%: Fixval.Sense With this parameter, a fixed gyro sensitivity is set for each individual flight phase. Alternatively, a control can be used.
Menus Suppression In Damping mode, the gyro also counteracts intentional control commands. For improved control, the gyro sensitivity can be suppressed proportionally to stick travel using this parameter. This function is already integrated in many gyros. In this case, retain the value OFF. Adjustment range: OFF to 200% The setting 200% reduces damping to 0% at half stick travel. If the gyro has its own suppression function, set the value to OFF.
Menus 5.4.6 Collective (only helicopters) The Collective control function is only available for helicopter models that are controlled using collective pitch. The curve for the "Collective" control function is set here. A separate collective pitch curve with 7 curve points is provided for each flight phase. Refer to section 8.2.9 "Setting the collective pitch curve" on page 206 for examples of collective pitch curves.
Menus 5.5 Mixer main menu You configure the mixers in this menu. The menu is partially dynamic: The menu content differs for fixed-wing models and helicopter models. Mixers on the servo side are only listed if they are in use, i.e. they are assigned to a servo. Mixers on the control side are always listed, e.g. "Combi-Switch", "Differnt.Ail". Opening the main menu To open the main menu: 5.5.1 button Fixed-wing models Overview The mixers Combi-Switch, Differnt.Ail, and Ctrl.
Menus 5.5.1.1 Combi-Switch The Combi-Switch couples aileron and rudder in a way that allows both of the control functions to be controlled by either of the functions. This makes it easier to fly accurate turns. The Combi-Switch can be configured for specific flight phases. You define the associated switch in the Setup > Assign.Switches menu using the CS/DTC parameter (see section 5.3.6 "Assign.Switches" on page 102). Ail > rudder or Ail < rudder Percentage of the respective control function (%).
Menus Mode Possible values: OFF Differnt.Ail off ON Differnt.Ail on +SPOILER The +SPOILER mode should be selected if the ailerons are raised to use them as additional landing aid. This suppresses the differential when operating the landing aid (Spoiler control function). As a result, the aileron travels are not reduced in the downward direction, enhancing aileron response during landing. Differnt.Ail Flight phase specific setting for the differential level.
Menus Switch Switch for deactivating the mixer. Without the switch the mixer is switched on. All three components Source, Target, and Switch can be selected by operating a switch, using the central wheel or pressing the + or - button. Press the REV/CLR button to erase Source and Target. The Switch is inverted when pressing the button the first time and erased when the button is pressed again. Pressing the button a third time restores the original setting.
Menus 5.5.1.4 Mixers on the servo side "Mixers on the servo side" combine up to 8 control functions in one common output signal. You can assign a unique name to each mixer. It is possible to assign the output signal to one or more servos using the name of the mixer. For safety reasons, the mixers are defined and configured in separate main menus. In this menu, only the travels and other parameters are configured. Only mixers are shown that are actually used, i.e. that are assigned to a servo.
Menus 5.5.2 Helicopter models Overview The 4 Ctrl.Mix mixers are always shown. The other mixers are only displayed if at least one servo is assigned. In the model templates HELImech., HELIccpm, and eHeli FBL, the TAIL ROTOR mixer is assigned to a rotor and is, therefore, shown here. Servos are assigned to the main rotor mixers in the HELIccpm template; as a result, MAINROTOR is displayed here. The MAINROTOR mixer is shown if it is assigned to one of the servos MAINROTOR-R.
Menus A 2-point calibration is sufficient for TAIL ROTOR. Take care that the servo is not stalled (mechanically obstructed) at its end-points (P1, P5)! All settings for throttle and collective pitch must be completed before the TAIL ROTOR mixer is configured. Subsequent changes usually require a correction. The TAIL ROTOR mixer is only activated in the Damping mode of the gyro. In Heading mode, it is switched off (see section 5.4.5 "Gyro" on page 122).
Menus 5.5.2.2 MAINROTOR You control the main rotor of your helicopter model with the MAINROTOR mixer. The PROFI TX features a universal swashplate mixer (CCPM) which can be used to control all types of swashplate fitted with three or four linkage points / servos. Refer to section 8.2.5 "Checking and adjusting the main rotor" on page 197 for information on how to check and adjust the main rotor and for a detailed description of the workflow for the MAINROTOR mixer.
Menus Example 1: 3-point 120º swashplate Geometry +120 Rotation +0 MAINROTOR-R. MAINROTOR-L. 120 Flight direction MAINROTOR-FB Example 2: 4-point 90º swashplate Geometry -90 Rotation +0 MAINROTOR-FB 90 MAINROTOR-L. MAINROTOR-R. Flight direction MAINROTOR-4 Rotation Virtual swashplate rotation; the parameter is required in the following cases: o The swashplate is physically installed in the model in such a way that the MAINROTOR-FB servo is not located on the centreline.
Menus If virtual rotation is required in the clockwise direction (when swashplate is viewed from above): negative values for rotation If virtual rotation is required in the anti-clockwise direction (when swashplate is viewed from above): positive values for rotation Lever +/Only required for 3-point swashplates whose linkage points are not equidistant from the rotor shaft centre for mechanical reasons.
Menus TIP Once you have entered the mechanical values of the swashplate as parameters for the MAINROTOR mixer, the next step is to carry out a careful and thorough calibration of the head servos in the Servo > Calibrate menu (see section 5.6.1 "Calibrate" on page 139). This step is essential to ensure accurate swashplate control. The direction of servo rotation can be checked using collective pitch control commands.
Menus 5.5.2.3 Ctrl.Mix These "mixers on the control side" mix the signal of any second (Source) control function into any (Target) control function. The mixer takes effect on all servos that are connected to the target control function either directly or via mixer. In helicopters, these mixers are typically used for throttle compensation. Four of these mixers are provided in the helicopter templates. Refer to page 128 for a detailed description of the Ctrl.Mix mixers. 5.5.2.
Menus 5.6 Servo main menu You can use this menu to configure, manage and monitor servos.
Menus 5.6.1 Calibrate You can use the Calibrate menu to adjust the travels, centre and any intermediate points for all servos so that they move evenly and run to the endpoints required. The menu shows a list of all the servos which can be used with your transmitter type (9, 12, or 16 servos). The sub-menu is identical for all servos. Any parameter changes are immediately reflected in the graph. The channel number (receiver output) of the selected servo is shown above the graph.
Menus TRM must only be used for corrections during operation! Use the TRM servo trim only to compensate for deviations from the neutral position of a servo that are identified during operation. When configuring a new model it is better to define the points separately. P1 to P5 The number of configurable servo calibration points (min. 2, max. 5 points) varies according to the setting selected when initially assigning the servos (see section 5.6.2 "Assignment" on page 5.6.2).
Menus Procedure 1. Adjust the direction of servo rotation. o Servos controlled by basic functions (e.g. Aileron, Elevator, Rudder, ...): First, check that the rotation direction of the controlled surface correlates to the control movement. If required, change the rotation direction in the REV/TRM parameter (REV/CLR button). If the rotation direction is changed later, you will need to re-calibrate it. o Servos controlled by mixers (e.g. AILERONS+, DELTA+, V-TAIL+, ...
Menus 5.6.2 Assignment You can use the Assignment menu to assign a control function or a mixer to your servos. The menu shows a table of all the servos which can be used with your transmitter type (9, 12, or 16 servos).

Operating the transmitter 6.4 Assigning controls to control functions The assignment for controls and switches defines which functions in the transmitter or model are controlled by which control. Controls, i.e. actuators, are: Sticks Slide potentiometers Rotary potentiometers Switches and their designated buttons Controls can be assigned to control functions and/or switched functions. Multiple assignments are possible and quite useful, e.g.
Operating the transmitter Controls mode Ailerons, elevators and rudders are controlled by the stick units. The stick units are assigned to the individual axes using the standardised controls mode (1 to 4). You configure the controls mode in the Setup > Assign.Controls > Ctrl Mode menu (see section 5.3.5 "Assign.Controls" on page 101). One vertical axis always remains unassigned (¢ icon) and can be assigned using the assignment list.
Operating the transmitter Assignment list To assign a control function proceed as follows: 1. Move the input cursor to the control function you wish to assign a control to. 2. Open the input field. 3. Assign a control by pressing the + / – buttons, by using the central wheel or by operating the control. 4. To set the actuation direction keep the control in the desired zero position and close the input field.
Operating the transmitter Control functions of the model templates The following control functions are defined in the PROFI TX model templates. The control functions 1 to 3 are assigned using the controls mode.
Operating the transmitter 6.4.2 Assigning switches Switches are controls that toggle functions or switch functions on/off. Switches are assigned in the Setup > Assign.Switches menu (see section 5.3.6 "Assign.Switches" on page 102). This menu includes a list of the switchable functions provided in the software. You can use this menu to customise the switches assignment according to your needs. To assign a switch proceed as follows: 1.
Operating the transmitter Switch Description Frame Frame timer Sum Sum timer Interval Interval timer Variometer Tone of the variometer Teacher For transferring control functions to the student Phase 4 Switches from every flight phase to phase 4 Phases 1-3 For switching between the flight phases. Sensor Alarm For clearing the warning bar and for switching the sensor alarm tone off. Use a 3-position switch. In end position ON (*) the warning bar and the vibration alarm are cleared.
Operating the transmitter MagicSwitch The PROFI TX features 2 MagicSwitches. A MagicSwitch is a logical switch which can be assigned and inverted like a real control. It combines up to three switches (including the second MagicSwitch and flight phases) in an AND function. Unused inputs are considered switched on. The MagicSwitch is switched on when all switches that are assigned to it are switched on. MagicSwitch output switches with a configurable delay. OFF and ON delays can be configured separately.
Operating the transmitter using the PC 7 Operating the transmitter using the PC You can use the supplied USB cable to connect the PROFI TX to any PC or tablet featuring an operating system that supports USB mass storage and an USB port that is compliant with the USB standard (4.5-5.5V / 500mA). Some laptops and tablets are not compliant with this standard. The following functions are available when the transmitter is switched off (charging mode): Charging the battery; refer to section 3.4.
Operating the transmitter using the PC Die PROFI TX switches on automatically when it is supplied with charging voltage. The USB icon is shown on the right side of the screen and the state of charge and the charging current are displayed on the left. The PROFI TX logs into the PC as mass storage (drive) with the name "PROFI TX". Open this "drive". It contains the following folders: 7.2 DATA; contains the model memories, see section 7.2 "Editing ".
Operating the transmitter using the PC 7.3 Software update The "Update" folder on the PC is used for updating the software on your PROFI TX and for changing the language pair. 1. Connect the transmitter to the PC. 2. Open the "PROFI TX" mass storage. 3. Place the update file in the "UPDATE" folder. 4. Switch on the transmitter. The update process starts automatically when an update file is found in the "Update" folder. The file name of the update is displayed on the transmitter screen.
Operating the transmitter using the PC 7.5 Model flying simulator You can use the PROFI TX to control a model flying simulator in two ways: Via USB cable Via M-LINK in conjunction with the MULTIFlight stick In both cases, you have the following options: Would you like to work in simulator mode without configuring "Travel", "Expo" and "Trim"? Switch ON "Training" in the Setup > Training menu (see page 96). Select the Student mode.
Operating the transmitter using the PC 7.5.1 Via USB cable If the PROFI TX transmitter is operating in normal mode and is connected to the PC via USB cable, it logs into the PC as a game controller. Upon first time use, Windows automatically installs the required drivers. This may take several minutes. Neither the transmitter nor the PC must be switched off while the driver installation is in progress.
Operating the transmitter using the PC 7.5.2 Using the MULTIFlight stick Insert the MULTIFlight stick in a free USB socket on your PC. Wait until the driver installation process, which starts automatically, is completed. Now, you have to bind stick and transmitter. Press and hold the MULTIFlight stick button until the yellow LED starts to flash. Switch on the transmitter. Open the Setup > M-LINK menu. Activate the binding as described on page 93.
Operating the transmitter using the PC 7.5.3 MULTIFlight simulator The simulator is available as freeware download on our website: www.multiplex-rc.de Two options are available for configuring the PROFI TX transmitter for simulator mode: Would you like to use "Trim", "D/R", "Expo", "Combi-Switch" and "Ctrl.Mix"? Create a new model using the BASIC template (page 155) and change the model name (page 157), e.g. to Simulator. Safety check can be switched off.
Creating and customising models 8 Creating and customising models The following chapters contain detailed descriptions of the menus and how the transmitter is operated using the keypad or central wheel: "Menus", see page 86 "Operating the transmitter", see page 160 8.1 Fixed-wing models 8.1.1 The procedure in principle A model memory for a glider is created in this example. The procedure for power models is identical.
Creating and customising models 5. Open the Memory > Edit name main menu and enter a unique and descriptive name for the model (see section 5.8.4 "Editing names" on page 157). 6. Assign the desired controls (actuators) to the control functions in the Setup > Assign.Controls menu (see section 5.3.5 "Assign.Controls" on page 101). Pay attention to the zero positions (' / #) of the controls for Throttle and Spoiler! 7. Connect the servos as shown in the following figure.
Creating and customising models 8.1.3 Adjusting rotation direction and maximum travels for the servos / control surfaces Use electronic means as little as possible to reduce the servo travels. Otherwise, you will forfeit servo resolution! If possible, implement major changes using control surface linkages. 8.1.3.1 Configuring aileron differential 1. Open the Mixer > Differnt.Ail menu. 2. Set Mode to ON and Differnt.Ail to 100%. 3. Set aileron travel to the left.
Creating and customising models 2. Open the REV/TRM parameter and set aileron travel to the left. If the left aileron does not move up, reverse the servo using the REV/CLR button. 3. Move the aileron stick to the centre position. Move the control surface to the neutral position using the central wheel or the + / – buttons. The setting range is +/-10%. Offsets exceeding 5% should be corrected mechanically. 4. Open the input field P1. 5. Press the button: . Both ailerons move to maximum. 6.
Creating and customising models 14. Choose a P1 and P5 setting so that control surface travels on the right aileron are identical to those on the left aileron: o Open the input field P1. o Press the F button. Both ailerons move to the negative maximum. o Use P1 to align the negative travel of the right aileron with that of the left aileron. o Open the input field P5. o Press the F button. Both ailerons move to the positive maximum.
Creating and customising models 8.1.3.3 Adjusting elevators 1. Open the Servo > Calibrate > 2: ELEVATOR+ menu. 2. Open the REV/TRM parameter and apply up-elevator. If the elevator moves down, reverse the servo using the REV/CLR button. 3. Move the control surface to the neutral position using the central wheel or the + / – buttons. The setting range is +/-10%. Offsets exceeding 5% should be corrected mechanically. 4. Correct the maximum servo travels using P1 and P5 (see section 8.1.3.
Creating and customising models 8.1.3.5 Adjusting flaps 1. If your model has inboard flaps perform step 1 to 4 in section 8.1.3.1 "Configuring aileron differential" on page 183 for the inboard flaps. 2. If your model features mechanical airbrakes, extend them using the assigned controls. Check and correct the actuation direction in the Servo > Calibrate menu for servos 8 and 9. 8.1.3.6 Adjusting the power system 1.
Creating and customising models 8.1.5 Using camber-changing flaps as spoilers If your model has inboard flaps, you should use the camber-changing flaps also as airbrakes (spoilers): 1. Open the Mixer > FLAPS+ menu. 2. Set the value for the Spoiler > Travel parameter to 100%. 3. Move the control for the Spoiler control function to maximum. If both flaps do not move down, reverse the travel using the REV/CLR button. 4. Reduce both travel distances, up and down, of the aileron.
Creating and customising models Other control functions: If required, assign other control functions to unused servo channels in the Servo > Assignment menu (see section 5.6.2 "Assignment" on page 142). V-TAIL+: In the Servo > Assignment menu, reassign servo channels 2 and 3 from ELEVATOR+ / Rudder to V-TAIL+. Then, adjust the rotation direction and travels in the Mixer > V-TAIL+ menu (see section 5.5.2.4 "Mixers on the servo side" on page 137).
Creating and customising models 8.2 Helicopter models 8.2.1 The procedure in principle A model memory for a helicopter with 120° CCPM rotor head and electric power system is created in this example. The following steps are required to ensure correct operation of the basic model functions: 1. Creating a new model in the transmitter, see page 190 2. Preparing controls and switches, see page 191 3. Checking and changing servo assignment, see page 194 4.
Creating and customising models Selecting a template Thanks to pre-defined model templates (see page 53) new models can be created more easily and quickly since the basic configuration is more or less completed by selecting the template. You can use the Memory > Edit name menu to find out which template was used for model creation. 4. Select the HELIccpm model template for the Template parameter. Inheriting parameters from the active model 5.
Creating and customising models Editing the model name The new model that is created has the same name as the template used: HELIccpm. For easier reference, you should change the name to the actual model name: 7. Open the Memory > Edit name menu. 8. Enter a name (max. 16 characters) that clearly identifies the model. Refer to page 157 for details. The creation of a new model in the memory is now completed.
Creating and customising models Switch assignment The Setup > Assign.Switches menu contains: Function Switch You can use this switch to alternate from the CS/DTC throttle curve to direct throttle control using the throttle limiter. Useful for configuring I.C. engines. Do not use any button here! Throttle-cut ´ Sum F ' Switch for the sum timer, controlled by control F> (throttle limiter). The sum timer records the motor run time.
Creating and customising models 4. Operate the throttle stick vigorously. Leave it in idle position. The direction arrow points to the current position of the stick. Never change the assignments and/or rotation direction of controls and switches when the model is switched on. Power systems and servos may start up unexpectedly and cause damage. 5. Confirm the change by pressing ENTER. Proceed as described above to change the minimum position for the throttle limiter.
Creating and customising models 8.2.4 Checking and changing servo assignment The servo assignment defines: The receiver output controlling the servo The number of curve points (2, 3, or 5) used for adjusting the servo travel Defaults The rotor head servos and the servo gyro have 3 curve points (the centre can also be set). Throttle and tail rotor have 2 curve points for a linear characteristic (only end-points must be set). Procedure 1. Open the Servo main menu. 2. Open the Assignment menu.
Creating and customising models 8. Set the number of curve points to 2P. Only the end positions then require setting. This always yields a straight line between the points. 9. Confirm the change by pressing ENTER. Servo 3 and servo 4 are now swapped. All the head servos are in sequence.
Creating and customising models 8.2.5 Checking and adjusting the main rotor Secure the model when you set the rotation direction, centre, and travels for the servos to prevent danger or damage due to unexpected reactions. 8.2.5.1 Checking / changing direction of servo rotation on the rotor head The directions of travel for the servos must be checked and changed (if required) before centre and travel are set.
Creating and customising models If you move the collective pitch stick slightly from the neutral position before pressing the REV/CLR button, the servo will jump to the new position when you reverse it. This is an easy way to check that you have selected the "correct" servo. 6. If the rotation direction is correct, confirm the change and exit the menu. 7. Select the next servo that you want to edit.
Creating and customising models First, perform a hardware calibration: Press the F button. This generates the "true" centre, without the influence of the trim or mixer inputs on the servo. If the servo is not in the desired centre position at this stage, it is essential to correct the control surface position mechanically (by re-positioning the output arm on the servo, or otherwise adjusting the linkage). Wherever possible, the fine-tuning for point P3 for the servo calibration should not exceed ±15%. 5.
Creating and customising models Setting the maximum servo travel (control surface travel) At this point, set the maximum required value for blade deflection; this is generally the auto-rotation value. The smaller values required for normal flying can be set for the individual flight phases in the ControlFunctions menu under Collective. 1. Open the Servo main menu. 2. Open the Calibrate menu. 3. Select a servo. 4. Select the P1 menu item and open the parameter. 5. Press the F button.
Creating and customising models 8.2.6 Checking and adjusting the tail rotor 8.2.6.1 Checking / changing the direction of servo rotation for the tail rotor The direction of servo travel must be checked and changed (if required) before centre and travel are set. When entering the basic settings do not connect the tail rotor servo via the gyro, but directly to the respective receiver output. This ensures that the gyro has no effect on your settings.
Creating and customising models Coll.+ / Coll.- (REVO-MIX) You can use the Coll.+ / Coll.- parameters to set the collective pitch mixers for the tail rotor separately for climb and descent, and for each flight phase: Coll.+: correction for climbing Coll.-: correction for descending The exact values can only be established through a programme of flight testing, and vary according to many parameters. Zero point The origin for the static tail rotor compensation mixer is set under Zero point.
Creating and customising models 8.2.7 Gyro The Gyro control function is intended for gyro systems which allow radio-controlled configuration of the sensitivity via a servo channel. If Gyro is not assigned to a servo channel, this function is not available in the Controls menu. 1. Open the Controls main menu. 2. Open the Gyro menu. The gyro type Heading is selected by default in the model templates. The fixed value for sensitivity setting is switched off (OFF).
Creating and customising models In controls mode, gyro sensitivity can only be set manually using the Gyro control function (factory setting: slider E). To this end, Fixval.Sense must be set to OFF. The next line now shows the position (50%) and control (
Creating and customising models 8.2.8 Throttle Does not apply to the FUNCOPTER template! For throttle-controlled helicopters, the simple throttle setting of fixed-wing models is used. See chapter 5.4.2 on page 117. The Throttle control function can be adjusted using 7 curve points or using a fixed value when the electric power system operates in Governor mode. Each flight phase has a specific curve. Only in the AUTOROT flight phase, all the curve points have the same value (yielding a straight line).
Creating and customising models Sometimes, it can be useful to operate the throttle directly without any restrictions. To do so, assign a switch to the CS/DTC switched function as described on page 104. When this switch is in ON position, the limiter controls the throttle directly. 8.2.9 Setting the collective pitch curve Does not apply to the FUNCOPTER template! Throttle-controlled helicopters do not feature collective pitch control.
Creating and customising models 8.2.10 Working with flight phases Requirement To allow working with flight phases, at least one switch must be assigned in the Setup > Assign.Switches menu (either for Phase 4 or Phases 1-3). Otherwise, the transmitter always operates in Phase 1. For each flight phase, you can customise the control characteristics on the transmitter according to the requirements of the model (e.g.
Creating and customising models Names are pre-assigned to all four possible flight phases. However, those can be edited using the + / – button or the central wheel. 8.2.10.2 Assigning switches for flight phases At least one of the two switches must be assigned before you can use different control settings in the flight phases: 1. Open the Setup main menu. 2. Open the Assign.Switches menu. 3. Select Phases 1-3 and open the parameter. 4. Move switch I to the ON position (* must be visible).
Creating and customising models 1. Open the Setup main menu. 2. Open the Flight phases menu. 3. Select the respective flight phase in the menu. 4. Every time you press the REV/CLR button, the flight phase toggles between locked and unlocked. 5. Confirm the change. 8.2.10.4 Copying flight phases Once you have established the correct settings in one flight phase, you can copy the values into another flight phase and then modify them. This avoids the need to re-enter all the settings from the start.
Creating and customising models 8.2.10.5 Changing flight phase names You can select any of the 13 pre-set names for the flight phases: 1 NORMAL 6 SPEED1 11 HOVER 2 START1 7 SPEED2 12 3D 3 START2 8 CRUISE 13 ACRO 4 THERMAL1 9 LANDING 5 THERMAL2 10 AUTOROT After activating the input field for the name, select a suitable name by pressing the + / – buttons or by using the central wheel.
Maintenance and care 9 Maintenance and care The transmitter does not require any special maintenance or care. However, we strongly recommend that you have the transmitter checked by an authorised MULTIPLEX Service Centre at regular intervals (every two or three years), depending on the intensity of use. Regular functional and range checks are mandatory (see section 3.6 "Range check" on page 47).

Glossary of technical terms Glossary of technical terms Allocation Permanently assigning a set value to a digi-adjuster. Assignment Defines which functions in the transmitter or model are controlled by which control. Battery management Determines the remaining operating time (time to empty), the capacity and other battery data from the current and voltage characteristics. Optimises the charge / discharge limits for a long battery life.
Glossary of technical terms Differential Indicates the percentage by which the travel distance of the control surface down is reduced relative to the travel distance up; if the differential is set to 50%, the travel distance down is half as great as the travel distance up. The higher the % value, the shorter the travel distance of the control surface down. Differential is required because the downward control surface generates greater drag than the upward control surface.
Glossary of technical terms Expo Generates a non-linear control function. For Expo = 0%, the control works in a linear fashion. The effect of negative values is that smaller control surface travels are generated around the centre position with the same stick travel, thus providing finer control. The effect of positive Expo values is that control surface travels are increased around the centre position. The end-points remain unchanged.
Glossary of technical terms Mode Defines the assignment of the main control functions Aileron, Elevator, and Rudder to the stick units. Model template Template for creating new models; thanks to model templates, new models can be created more easily and quickly since the basic configuration is more or less completed by selecting the template. Model templates also contain the basic configuration for mixers, controls, servos and flight phases.
Glossary of technical terms Throttle curve Only used for helicopters. The throttle curve of the PROFI TX has 7 points and determines how much throttle is assigned to the various individual positions of the collective pitch stick. The aim is a constant speed, i.e. the higher the collective pitch, the more the throttle is advanced. Throttle limiter Only used for helicopters. Restricts (limits) the maximum possible throttle value. This allows safer model setups.
