FX-40 1. SAFETY NOTES: OBSERVE AT ALL TIMES Safety notes ROUTINE PRE-FLIGHT CHECKS If there are several modellers at your site, ensure that yours is the only transmitter on “your” frequency before you switch on the transmitter. Please take the trouble to read right through these instructions before attempting to use the equipment for the first time, paying particular attention to the safety notes.
FX-40 The FX-40 is a premium-class radio control system which sets new standards in many areas. Introduction The data can also be stored and backed-up on a PC which has a Compact Flash Card reader; it can also be sent by email. 2. GENERAL DESCRIPTION • • • • • • Third-generation PCM system (PCM-G3) offering unsurpassed transmission speed and accuracy.
FX-40 3. SET CONTENTS 1 FX-40 FM transmitter with FX-FM RF amplifier 1 LT4F 5000 Lithium transmitter battery, 7.4 Volts / 5000 mAh 1 12 Volt automatic Lithium battery charger, 7.
FX-40 5.1 GENERAL INFORMATION The FX-40 transmitter is supplied with all transmitter controls installed as standard: Four stick controls • • Three linear proportional controls (L1 … L3) • Three central rotary knobs (LD, CD, RD) • Six rotary trimmers (T1 … T4, T7 + T8) • Two digital trim buttons (T5 + T6) • Four left-side switches (SA, SB, SE, SF) and four rightside switches (SC, SD, SG, SH) plus one momentary pushbutton in the rotary knob (CD-SW).
FX-40 Transmitter controls In the Linkage menu “Dial Monitor” the current and stored positions of the rotary knobs are displayed in bar graph form. The centre rotary knob CD is a digital control with no endstops, and it also features an integral push-button function (CD-SW). This control can also be assigned freely to any function. The transmitter emits an audible signal when the knob is moved to the centre position. The position of this control is also displayed on the Start screen.
FX-40 Transmitter controls the graphic LCD screen, with the result that the screen acts as an input method as well as just a display medium. It can be operated using a finger-tip or the stylus (supplied in the set). 2. 3-D Hotkey and Direct buttons The software menu system can also be controlled by turning and pressing the 3-D Hotkey. Rotating it selects the function, while pressing activates it.
FX-40 5.2 STICK ADJUSTMENTS • Stick adjustment Stick ratchet / brake The stick units feature both a ratchet function (fixed-wing models) and a brake function (helicopters) for the throttle function, which does not have a self-neutralising action. It is possible to activate this function and adjust the ratchet / brake force. Naturally, this adjustment can only be carried out on the throttle stick (depending on the stick mode).
FX-40 5.4 DATA PACK CFDP32M The Data Pack (Compact Flash) card supplied can be used to store pictures, music and sound as well as model memory data. The memory card is a standard commercial CF card, and has a capacity of 32 MB. CF cards are widely avail ble as digital camera accessories, and other makes of card can certainly be used in the transmitter. However, the variety available is extremely wide, and it is not possible for us to guarantee that all of them will work propely.

CHANGING THE SPOT FREQUENCY The system incorporates a DD Synthesizer system which generates the spot frequencies.
FX-40 • • • • • The screen now shows a confirmation display, enabling you to check the new spot frequency. The software asks you if this information is now to be transmitted to the receiver. Press “Yes” to confirm this. At this stage the RF transmission of control signals to the receiver is switched off. Changing the frequency band 9.
FX-40 • • • • • • Press the Modulation button Select the modulation you wish to use, and press “Enter”. The screen confirms your choice with the message “Modulation type is changed. sure ?” Confirm your selected modulation by pressing “Yes”. The radio link to the receiver is now switched off. The screen now asks whether you wish to re-activate the radio transmission of the control signals (Yes), or to continue without transmitting an RF signal (No).
FX-40 Start display 10. DESCRIPTION OF THE START DISPLAY The most important information relating to the transmitter programming is displayed on the Start screen. At the same time most of the display fields also constitute operating buttons, and you can move to the Set-up menu for the appropriate function simply by pressing the corresponding area of the screen. Flight condition name Press to call up the Select menu. Model name Press to call up the Model Select menu.
FX-40 11. MENU STRUCTURE, METHOD OF NAVIGATING Menu structure Navigation sub-level; in this case you can move to the next page or level by pressing the button field (1) at the top right-hand corner of the screen. Set-up menus which are regularly required, e.g. the frequency select menu, can be accessed directly via a button field from the start display (see also description of the Start display on the previous page).
FX-40 Select menus 12. SUMMARY OF SELECT MENUS 12.3 MODEL MENU (FIXED-WING AIRCRAFT) 12.1 SYSTEM MENU This menu contains the settings specific to each model type for each model memory, especially mixer functions. The Select menu varies according to the model type you have selected: This menu is used to adjust transmitter settings which apply to all models, i.e. they are non model memory-specific. Servo Monitor Condition Select AFR (D/R) Prog.
FX-40 13. BASIC INFORMATION ON OPERATING THE TRANSMITTER MODEL TYPE CHANNEL SEQUENCE Model type superfluous mixer functions are suppressed in the on-screen display to avoid confusion. The mixer functions required for any model vary greatly according to the model type. This is the basis for the new operating philosophy introduced in the FX-40 system.
FX-40 Curve set-up This section deals with the method of setting the characteristics of a transmitter control, using the transmitter control travel (AFR) menu as an example. When you select the AFR menu the software suggests the default linear 3-point curve.
FX-40 Curve set-up EXP1 = 3-POINT CURVE (EXPONENTIAL) The “EXP1” function is used to alter the characteristic curve of the transmitter control into a non-linear (exponential) curve, symmetrical around the centre point. The exponential curve can be applied in either direction. • Positive prefix: strong control response around the neutral position, reducing towards the end-points. • Negative prefix: weak control response around the neutral position, increasing towards the end-points.
FX-40 Curve set-up LINE = 17-POINT CURVE AND SPLINE = 17-POINT CURVE, ROUNDED The methods of setting and adjusting the Line and Spline curves are identical; the only difference with the Curve variant is that the transitions at the points on the Spline are mathematically rounded, producing a more harmonious shape.
FX-40 System menu 14. PLAYER, FOR PLAYING MUSIC FILES The Player is used for playing back music files in Windows Media Audio Format (wma). The player does not support the mp3 file format; such files have to be converted to wma format before they can be played. If you visit the T14MZ / FX-40 support page of the robbe website you will find information on locating free programs designed for converting mp3 files into wma format.
FX-40 System menu 15. SYSTEM MENU This menu is used to adjust the basic transmitter settings, i.e. the settings which are not specific to individual model memories. Settings entered here apply to all model memories.
FX-40 System menu The Teacher and Pupil have control of the model according to the position of the Trainer switch. 15.1 TRAINER (TEACHER / PUPIL FUNCTION) Trainer (teacher-pupil, buddy-box) operations make it possible for newcomers to learn the art of model flying with the help of an experienced pilot (Teacher). • NORM MODE In this mode the corresponding channel is also transferred to the Pupil transmitter.

FX-40 System menu 15.4 USER NAME, USER NUMBER, SECURITY MODE 15.3 DATE, TIME, CALENDAR, SYSTEM TIME This Set-up menu allows you to set the time of day and the date. The menu also includes a calendar function covering the years 2000 … 2099. A further timer shows the system time (power-on time), and therefore doubles as an operating hours timer, and also as a run-time display for the battery in use. Calendar for the years 2000 to 2099. Press the arrow buttons to leaf through the calendar forward or back.
FX-40 15.5 SWITCH - SWITCH TYPE ASSIGNMENT System Menü 15.6 TRANSMITTER CONTROL SETTINGS / REVERSE STICK RESPONSE TIME ADJUSTMENT It is possible to alter the physical position of the switches A … H; the procedure is described on page 7 of these instructions. If you make changes to the physical location of the switches compared to the standard arrangement, you will also need to adjust the software accordingly, otherwise the on-screen graphical display of switch positions will not be correct.
FX-40 15.7 INFORMATION This menu provides information about the currently installed version of the operating system and the application software. Linkage Menu 16. LINKAGE MENUS The table below shows a summary of the Linkage menu functions, which are described individually in the next section. In these menus you can set and store the linkage settings for individual models or model memories, under individual model names.
FX-40 16.1 SERVO MONITOR The Servo Monitor menu displays all servo travels in a clear form using a bar graph and percentage values. The travels are those which are generated by all the set adjustments and mixer functions. This constitutes an ideal test program for checking control surface travels manually, or for testing all servos automatically. NOTE: The servo monitor takes into account all the adjustments you may have made, including Limit, Dual-Rate, transmitter control travel (AFR) etc.
FX-40 Linkage Menu 16.2 MODEL SELECT - MODEL MEMORY SELECT New model memory In this menu you can select the actual model memory file you wish to use, but it is also designed for model data handling tasks generally, such as creating new memories, copying, erasing and renaming. Each model memory takes up a space of around 132 kB. Thirty models can be stored internally, while the 32 MB DP card supplied as standard can store approximately 200 models.
FX-40 Linkage Menu 16.3 MODEL TYPE - MODEL TYPE SELECT MODEL TYPE HELI This is the menu where you select the model type, wing type and tail type for fixed-wing model aircraft, and the type of swashplate mixing for model helicopters. The software then suggests the appropriate mixer functions in accordance with the selected model type. This reduces the screen display to the minimum required, and helps to avoid confusion.
FX-40 Linkage Menu IMPORTANT: Pictures must be located on the D/P card. The transmitter only searches for images in that location, and if they are stored anywhere else, they will not appear in the preview. 16.4 PICTURE - LINKING PICTURES / PHOTOS In this menu point you can assign a picture of the model to the appropriate model memory; the picture is then shown in the base and start displays. The model picture is displayed when the transmitter is switched on.
FX-40 Linkage Menu 16.5 SOUND (MUSIC / SOUND FILES) IMPORTANT: Sounds must be stored in the WAV folder on the D/P card. The transmitter only searches for sounds in that location, and if they are stored anywhere else, they will not appear in the preview. In this menu point you can assign sound files to the various switched functions. Each switch position can be allotted its own sound, regardless of whether it is a physical switched function or the position of a transmitter control switch.
FX-40 16.6 Linkage Menu FREQUENCY SELECTING THE FREQUENCY CHANNEL AND MODULATION This menu has already been described in detail on page 20 in the Section entitled ‘Using the transmitter for the first time’, so it will only be repeated here briefly in order to maintain the correct sequence. Press the Frequency channel button, and a three-page selection of spot frequencies appears, showing all those which are approved for use in Europe.
FX-40 16.7 FUNCTION The transmitter employs a new, graphical method of selecting the model type as basis for the mixer functions and transmitter control arrangement (stick mode), and this automatically generates the optimum configuration for the selected model type. We recommend that you keep to this set-up if possible, so that you are always using a standard configuration.
FX-40 Linkage Menu VC 1 - 4 This set-up menu is used to configure the virtual functions VC 1 … 4. The term ‘virtual function’ is used to describe functions which use other channels as ‘double functions’, i.e. they do not have their own servo channels. Examples of this are the butterfly (crow) function, which controls the aileron and flap servos, or the elevator function of a flying wing model, where the ailerons have a dual function, ‘doubling up’ as elevators.
FX-40 16.8 SERVO CENTRE SERVO CENTRE OFFSET When you install the servos in a model, it is always best to position them in such a way that the servo output arm is in the neutral position when the trim control on the transmitter is also at centre. Sometimes the model’s restrictions make this impossible, and in other cases the neutral position is non-standard due to the use of different makes of servo.
FX-40 16.10 FAIL-SAFE FAIL-SAFE SETTINGS This function is only available in PCM-G3 or PCM-1024 mode. This means that the corresponding modulation process must be set at the transmitter, and a matching PCM receiver must be installed in the model. In the Fail-Safe menu you can set the following parameters for channels 1 … 12: Linkage Menu The warning position for the selected servo is entered using the method already described; the value is displayed onscreen in the form of a percentage.
FX-40 16.11 END-POINT (ATV) SERVO TRAVEL SETTINGS (ATV) Linkage Menu It is usually only necessarily to set the servo end-points once for the maximum possible or desired travel, i.e. subsequent corrections are not generally necessary. Individual travel adjustments for particular flight modes can be entered in the transmitter control travel (AFR) menu, where you can set up curves with 2 … 17 points for each function, for a maximum of eight different flight modes.
FX-40 16.12 MOTOR OFF - MOTOR CUT-OFF FUNCTION This function enables you to cut the motor using a switch, without changing the idle trim. For fixedwing models and helicopters alike this is an elegant method of reliably stopping the motor. Mark the ‘Motor off’ option in the base menu. The screen now looks like this: Servo travel 16.
FX-40 16.14 Linkage Menu The swashplate menu has two display levels; pressing the field at top right takes you to the second level: Swashplate (AFR). The display changes, and the screen for setting up the mixer rates appears. It looks like this: SWASHPLATE BASIC SWASHPLATE SETTINGS This function is used to program the mixer functions required to actuate the swashplate of a model helicopter.
FX-40 Linkage Menu The default set-up is no switch, and the screen displays ‘NONE’. The same switch can also be assigned to individual options of the timer function. 16.15 STOPWATCH The Stopwatch menu is used to set up and adjust the electronic timers provided by the FX-40 transmitter. The timers are displayed in two on-screen windows, which means that you have constant access to two crucial times, for example: the overall flight time and the motor run time of an electric-powered model.
FX-40 16.16 16.17 TRIM / ADJUSTOR POSITION DISPLAY RESETTING DATA When you wish to enter the essential data for a new model, you will often need to start by erasing the contents of a model memory which you no longer need, or just certain areas of that memory.
FX-40 16.18 FLIGHT MODE HOLD The purpose of this function is to enable you to change the settings in a different flight mode. The motor is held at the ‘idle’ setting, to prevent it being switched on accidentally. CND HOLD can only be activated when the “Normal” flight mode is selected, and only if the throttle stick is at the idle position.

FX-40 17. MODEL MENUS Model menu • MODEL MENU - OVERVIEW OF MODEL HELICOPTERS This menu is used for programming the model type-specific settings for individual model memories - especially the mixer functions. This data is stored under the programmed model name in the appropriate memory. At the main screen activate the Model menu by touching the field showing the model aircraft picture. The overview of Model menus is now displayed. The Select menu varies according to the model type you have selected.
FX-40 17.1 SELECTING FLIGHT MODES Model menu Flight modes Mark the field for selecting the flight mode switch (currently NONE). The software of the FX-40 provides up to eight flight modes for each individual model memory. This feature ensures that you can always store the optimum settings for the various phases of a typical flight, and call them up as and when required simply by operating a switch.
FX-40 Model menu Flight modes delay time as standard. Now move to the ‘Delay’ column and mark the field for the channel which is to be assigned a delay time. You will now see an additional set of three button fields in the bottom right corner of the screen. The delay time can be increased or reduced using the two ‘Arrow’ buttons. Pressing the ‘Reset’ button restores the default value of ‘0’.
FX-40 17.2 TRANSMITTER CONTROL TRAVEL / DUAL RATE CURVE Model menu Transmitter control travel / Dual Rates Please note: the higher the number, the more slowly the servo moves. The maximum value (27 increments) corresponds to a duration of nine seconds. The default setting is always ‘0’. When you mark one of the fields ‘there’ or ‘back’, the button fields for the arrows appear at the right margin. It is possible to make adjustments in steps of one increment (single arrow) or ten increments (double arrow).
FX-40 Model menu Transmitter control travel / Dual Rates As an additional feature, the fields ‘Rate A and B’ can be marked to adjust the transmitter control travel separately for each side of centre. If you select a VTR curve, additional set-up levels become available. The values are entered individually for the right and left sides (RATE A and B), and the curve can be shifted vertically using ‘OFFSET’. The VTR curve points also have to be set as ‘P.POS’ and as ‘P.RATE’ for each side (A and B).
FX-40 17.3 PROGRAMMABLE MIXERS Model menu Programmable mixers You move to the actual programming masks by marking the appropriate field in the ‘Mixer’ column on the left. The display changes, and the first mixer programming menu appears. The FX-40 features ten freely programmable mixers which are available for every model memory, in addition to the fixed preprogrammed mixer functions.
FX-40 It is also possible to select a mode for the programmable mixer, i.e. linear (LIN) or symmetrical (SYM) mode; you can toggle between the two simply by touching the appropriate field. The linear mode is used for controlling the throttle servo or a switch; this mode is non self-neutralising. The alternative (symmetrical) mode is self-neutralising, and is the default setting for use with control surfaces.
FX-40 appropriate field, and select your preferred transmitter control in the menu which then appears. Any of the auxiliary transmitter controls can be used. Your selected control is displayed in the field, as shown in the screen shot. Linear: EXP1: EXP2: VTR: LINE: Curve: Next you should define the operating mode for the transmitter control you have chosen; the mode is selected using the standard procedure: mark the field containing the symbol indicating the effect of the transmitter control.
FX-40 If necessary, the mode of the Offset mixer can now be changed; two modes are available: Model menu Programmable mixers The programming of an Offset mixer is concluded by activating a switch using the standard procedure: mark the corresponding button field in the bottom line, and define the switch in the switch select menu which then appears. The direction of effect of the switch can also be set in the usual way.
FX-40 17.4 Model menu Mixture adjustment MIXTURE ADJUSTMENT (power model and helicopter model types only) This function is designed for fine-tuning the fuel mixture at the carburettor using a separate servo. A special advantage of this system is the ability to set up an inter-action with the normal throttle function. If you activate this option, the needle valve follows the operation of the throttle servo when you open or close the throttle, ensuring a reliable motor run when properly set up.
FX-40 You will find two button fields labelled ‘Current position’ (Cur. pos.); these are used to call up and adjust the current position of the throttle stick for the lower range from 0 to 49% (min.) and for the upper range from 50 to 100% (max.). The percentage values are displayed in their respective fields. Model menu Fixed-wing model aircraft 18. MODEL MENUS (FIXED-WING MODELS) In this Section we analyse the settings which are specific to fixed-wing model aircraft.
FX-40 18.1 AILERON DIFFERENTIAL Model menu Aileron differential Please follow the programming procedure described below: Differential aileron travel is often required on fixed-wing model aircraft in order to compensate for the phenomenon known as adverse yaw. When the aeroplane is turning, the outboard wing moves through the air more quickly, which means that the drag generated by the down-going aileron (on the outside of the turn) is greater than that of the up-going aileron.
FX-40 This screen shot shows aileron differential programmed to 50%. Model menu Wing flap settings 18.2 WING FLAP SETTINGS This menu is used for entering the settings for all the inboard wing flaps. If your Brake Brake model features Spoiler Spoiler flap flap two pairs of (FLAP2) (FLAP) (BRK1) (BRK2) inboard flaps (see diagram above) this menu applies to the inboard brake flaps and spoiler flaps, which are located adjacent to each other.
FX-40 Model menu Aileron -> flap mixer 18.3 AILERON -> FLAP MIXER 18.4 This menu is used to set the values for a mixer which causes the spoiler flaps Spoiler Spoiler Ailerons Ailerons (inboard flaps) (FLAP2) (AIL2 and to move in the (AIL and (FLAP) AIL4) AIL3) same direction as the ailerons when an aileron command is given. This mixer improves the roll rate of a model glider, because the flaps deflect to support the ailerons, thereby generating a greater roll moment.
FX-40 18.5 AILERON -> RUDDER MIXER Winglet (Rudder 4) Winglet (Rudder 3) Tip aileron (AIL3) Rudder 2 Main aileron (AIL) Main aileron (AIL2) Tip aileron (AIL4) Model menu Aileron -> rudder mixer • Selecting the fine-tuning settings It is possible to assign a switch or other transmitter control to the task of fine-tuning aileron differential; this is carried out in the ‘Fine tuning’ frame.

FX-40 18.9 ELEVATOR -> SPOILER (FLAP) MIXER Model menu Elevator -> flap mixer Once you have selected a transmitter control for finetuning, and programmed your preferred mode, you should determine the effect range for the fine-tuning procedure. The first step here is to mark the right field in the ‘Finetuning’ frame. The arrow buttons now appear at the right margin of the screen, and they are used to enter the effect range as a percentage figure; the set value is displayed in the appropriate field.
FX-40 18.10 FLAP -> ELEVATOR MIXER Right flap (FLAP2) Left flap (FLAP) ELE • Selecting the fine-tuning settings It is possible to program a switch or transmitter control which is used to carry out fine adjustments (fine-tuning) of the mixer settings. Mark the appropriate field and select your preferred transmitter control in the transmitter control / switch select menu which then appears. The default is ‘NONE’. Any of the auxiliary transmitter controls can be used.
FX-40 18.11 BUTTERFLY (CROW) MIXER If you wish to program a delay time to provide a smooth transition when you switch flight modes, you must first mark the ‘Delay’ line in the ‘Flight mode delay’ frame. You can now enter a setting using the arrow buttons. The adjustment range is 0 to 27 increments. Please note: the higher the number, the longer the delay. The maximum value (27 increments) corresponds to a delay of nine seconds.
FX-40 increments) corresponds to a duration of nine seconds. The default setting is always ‘0’. When you mark one of the fields ‘there’ or ‘back’, the button fields for the arrows appear at the right margin. Model menu Trim Mix 1 and 2 18.12 TRIM MIX 1 AND 2 This menu is used to set up mixers which apply to all the wing control surfaces and the elevators, Spoiler Main Main Spoiler separately for (FLAP2) aileron aileron (FLAP) particular flight (AIL) (AIL2) phases.
FX-40 Model menu Trim Mix 1 and 2 An Offset value can be entered separately for each control surface, by marking the appropriate field and then entering the required value using the arrow buttons. The adjustment range is +250% to -250%; the default setting is 0%. Pressing the ‘Reset’ field restores the default setting. The Trim Mix function first has to be activated in the Status line.
FX-40 18.13 GYRO SETTINGS Model menu Gyro settings This screen shot shows a sensible programming set-up for the Gyro function. If you wish to use a gyro in a fixed-wing model aircraft in order to stabilise one flight axis, this is the menu you use for entering the settings for the gyro. The basic purpose of this menu is to allow the pilot to adjust gyro gain (sensitivity) from the transmitter for a maximum of three gyros - i.e. one for each primary axis of the model aeroplane.
FX-40 18.14 V-TAIL SETTINGS 18.15 This menu presents all the mixer functions required for controlling a V-tail, which involves superimposing the signals from the rudElevator der and elevator controls at the (Rudder 2) Rudder (Elevator 2) transmitter. The travels of the elevator function (same-sense movement) and of the rudder function (opposite-sense movement) can be adjusted independently of each other. The sketch shows the assignment of the servos for a typical V-tail.
FX-40 Model menu Ailvator / Winglet 18.16 WINGLET RUDDER SETTINGS This menu presents all the mixer functions required for conRudder trolling rudder panels in the winglets of a fixedRudder2 wing model aircraft. These control surfaces have the same effect as a conventional rudder, but tend to be more effective since they are not located in the turbulent airflow from the propeller. This reduces drag, and therefore helps to improve flight performance.
FX-40 18.17 MOTOR SETTINGS Model menu Motor ‘Speed 1’ and ‘Speed 2’. This facility includes the option of setting different delay times for each direction of switching (‘there’ and ‘back’). Simply mark the appropriate field, then use the arrow buttons to set the desired value. The range is 0 to 27 increments, with the maximum figure corresponding to a delay of nine seconds. The default is no switch-over delay (0 increments).
FX-40 Model menu Rudder -> elevator Snap roll 18.18 RUDDER -> ELEVATOR MIXER 18.19 SNAP ROLL FUNCTION (flying wing models only) Many flying wings exhibit a tendency to dive slightly when a rudder command is given, and the purpose of this mixer is to cause the elevator to deflect up when a rudder command is given. This function may also be of interest to pilots who enjoy extreme 3-D aerobatics.
FX-40 Model menu Snap roll Multi-motor 18.20 MULTI-MOTOR SETTINGS FOR MULTI-MOTOR MODELS This function enables you to define the most important settings for controlling the motors in a model aircraft with up to four power plants. These settings are as follows: • • • • • The servo transit speed of all three control surfaces can be entered individually for each direction, separately for the ‘there’ and ‘back’ directions. A separate programming mask is provided in the second display level, as shown below.
FX-40 Model menu Model helicopters 19. MODEL MENUS (MODEL HELICOPTERS) This Section analyses the settings which are specific to model helicopters, i.e. it only covers those options which have not already been described in Section 17 (see page 54). Activate the Model menu by touching the field showing the picture of the model aircraft in the main picture screen. This calls up the overview of the Model menus. The Select menu varies according to the model type you choose.
FX-40 19.1 COLLECTIVE PITCH CURVE SETTINGS Operating the collective pitch stick moves the collective pitch servo or servos, but also automatically operates the throttle servo. The match between collective pitch and throttle is very important, and for this purpose the collective pitch function can be assigned one of six possible curve types, each of which can be allocated a maximum of seventeen variable points.
FX-40 A typical curve for the ‘Auto-rotation’ flight mode; the base curve is a linear type. For a ‘HOLD’ curve the motor is cut or moved to the Idle position - see ‘Auto-rotation’ menu (Section 19.4). The bottom collective pitch value has been reduced in order to maintain as high a rotor speed as possible as the helicopter falls. The maximum value has been increased to enable the model to flare out as smoothly as possible with a high collective pitch angle, and land safely.
FX-40 Separate: = Collective pitch curve for the current flight mode Fine: = Collective pitch curve for fine-tuning All modes: = Collective pitch curves for all flight modes Pitch & Throttle: = Collective pitch and throttle curves Model menu Collective pitch / throttle curve 19.2 THROTTLE CURVE SETTINGS Operating the throttle stick moves the throttle servo, but also automatically operates the collective pitch servos.
FX-40 motor speed remains as nearly constant as possible over the full range of collective pitch travel . For most applications a five-point curve is sufficient for this purpose. Model menu Throttle curve • Trimming the throttle setting The throttle trim can be optimised using the ‘Trim’ switch field, which is located at the left of the bottom line. Mark the field, and the display changes to look like this, e.g. for the ‘Hover’ flight mode: A typical curve for the ‘Idle-up 1’ flight mode.
FX-40 The ‘Display’ switch field is used to define which of the programmed throttle curves is to be shown in the graphic display, or which combination of curves. The options are as follows: Separate: Fine: All modes: Pitch & Throttle: Model menu Throttle curve / Acceleration 19.3 ACCELERATION FUNCTION The purpose of this function is to prevent abrupt changes affecting the throttle and collective pitch functions when you change the acceleration setting.
FX-40 19.4 AUTO-ROTATION SETTINGS Model menu Auto-rotation The next step is to set the carburettor position for auto-rotation, in the form of a percentage figure in the ‘Off Pos.’ or ‘Idle Offs.’ line. In ‘Off’ mode the motor is shut down completely, so the servo travel should be set accordingly. In ‘Idle’ mode the carburettor setting should be selected to move the motor to idle at a reliable but not excessively high speed.
FX-40 19.5 SWASHPLATE MIXER (virtual swashplate rotation) Model menu Swashplate mixer SET-UP EXAMPLE: SWASHPLATE MIXER Programming the swashplate mixer can be a complex procedure, so the next section describes a complete example in order to clarify the process. At the same time the associated mechanical procedures are explained. This function is used to set up the swashplate accurately over its full travel.
FX-40 Model menu Swashplate mixer tive pitch stick to max. collective, and set a value for the ‘Roll mixer’ to eliminate any change in the pitch-axis travel at full right or left roll travel. When you are satisfied, rotate the rotor through 90° and adjust the ‘Pitch-axis mixer’ in the same way. The final stage is to repeat the whole procedure with collective pitch set to minimum. The correct settings can then be set while you are still in the ‘Swashplate AFR’ menu.
FX-40 19.6 THROTTLE MIXER SWASHPLATE -> THROTTLE MIXER Model menu Throttle mixer vels of the transmitter stick (left and right): mark the field and enter the values required using the arrow buttons. The setting is displayed in the field as a percentage value. You can also enter a percentage value in the ‘Damping’ field; this determines how long the function is to remain active once the change in setting has been carried out.
FX-40 19.7 COLLECTIVE PITCH -> NEEDLE VALVE MIXER 19.8 This function is used to program an automatic needle valve adjustment which follows the movement of the collective pitch stick. It enables you to set the optimum fuel mixture at the carburettor (by adjusting the needle valve) whenever the load on the motor alters due to changes in the pitch angle of the rotor blades. An acceleration option can also be programmed to optimise this function.
FX-40 ting - regardless of the speed with which you change the setting. The same applies at the opposite extreme: when you reduce motor torque or the collective pitch setting, the helicopter must not rotate around its vertical axis. Model menu Collective pitch -> tail rotor Mixture adjustment 19.9 MIXTURE ADJUSTMENT This function is used to set up a separate servo for adjusting the fuel mixture at the carburettor. A particular advantage is that it is possible to link it to the normal throttle function.
FX-40 19.10 GYRO SETTINGS Model menu Gyro settings If you need to reverse the direction of effect, mark the field containing the prefix, and it will change from ‘+’ to ‘-’; the finetuning now works in the opposite direction to the previous setting. This function is used for adjusting gyro gain (sensitivity) from the transmitter. Gyro gain can be entered as a percentage, and it is also possible to select the gyro type.
FX-40 19.11 SPEED GOVERNOR SETTINGS Model menu Speed governor settings the transmitter to those of the GV-1 speed governor. Activate the speed pre-set (Rate 1, 2 or 3) for which you wish to carry out the calibration, then select the rotational speed display which is closest to the desired speed, and mark the corresponding field; three speeds (1000 rpm, 1500 rpm and 2000 rpm) are available for this. The pre-set is now displayed in brackets in the ‘Rate’ column.
FX-40 19.12 FLIGHT MODE HOLD Model menu Flight mode hold Notes on the stopwatch 19.13 NOTES REGARDING THE STOPWATCH WHEN USED WITH THE ‘HELICOPTER’ MODEL TYPE The purpose of this function is to enable you to carry out adjustments in another flight mode. The motor is held at idle to prevent the possibility of opening the throttle accidentally. The ‘Flight mode hold’ function can only be activated in ‘Normal’ flight mode, and even then only if the throttle stick is at the idle position.
FX-40 20. TIPS ON INSTALLING THE RECEIVING SYSTEM 20.1 INSTALLING AND USING RECEIVERS In the last few years the technical equipment carried in our models has undergone enormous changes. These include brushless motors and controllers, Lithium flight batteries, telemetry systems, GPS systems etc. etc., to mention just a few broad categories. At the same the materials used in our models have altered, with the widespread introduction of carbon fibre into the modelling world.
FX-40 The following solution has proved highly effective in practice: Mount the aerial on a hardwood former inside the fuselage, and run it through a hole of around 10 mm Ø in the fuselage. Insulate the aerial where it exits the fuselage with a piece of heat-shrink sleeving. Tips and notes • Turbines: • Connect the turbine shield plate using an earth strap to avoid the build-up of static charges. • Always fit a separate suppressor filter, No. F 1413, to the turbine ECU.
FX-40 radio control system. Never power an ignition system from the receiver battery; a separate battery is essential. Be sure to use properly suppressed spark plugs, plug caps and shielded ignition cables. Keep the receiving system as far away as possible from any ignition system. Tips and notes 20.10 SWITCH HARNESS It must be possible to operate the receiving system switch easily, without mechanical restriction, i.e.
FX-40 21.1 POWER-ON SEQUENCE Always switch the transmitter on first, and only then the receiver. Reverse the sequence when switching off. When you switch the receiver on, the servos run to the neutral position. If you are using a PCM system it is permissible to switch the receiver on first, and then the transmitter. This offers the advantage that the fail-safe data for all channels is automatically transferred to the receiver.
