Safety Notes

We all want you to have many hours of pleasure in our mutual hobby of modelling, and safety is an important aspect of this. It is absolutely essential that you read right through these instructions and take careful note of all our safety recommendations.

If you are a beginner to the world of radio-controlled model aircraft, boats and cars, we strongly advise that you seek out an experienced modeller in your ﬁ eld, and ask him or her for help and advice.

If you ever dispose of this transmitter, these instructions must be passed on to the new owner.

Application

This radio control system may only be used for the purpose for which the manufacturer intended it, i. e. for operating radio-controlled models which do not carry humans. No other type of use is approved or permissible.

Safety notes

SAFETY IS NO ACCIDENT

and

RADIO-CONTROLLED MODELS

ARE NOT PLAYTHINGS

Even small models can cause serious personal injury and damage to property if they are handled incompetently, or if an accident occurs due to the fault of others.

Technical problems in electrical and mechanical systems can cause motors to rev up or burst into life unexpectedly, with the result that parts may ﬂ y off at great speed, causing considerable injury.

Short-circuits of all kinds must be avoided at all times. Short-circuits can easily destroy parts of the radio control system, but even more dangerous is the acute risk of ﬁ re and explosion, depending on the circumstances and the energy content of the batteries.

Aircraft and boat propellers, helicopter rotors, open gear-

boxes and all other rotating parts which are driven by a motor or engine represent a constant injury hazard. Do not touch these items with any object or part of your body. Remember that a propeller spinning at high speed can easily slice off a ﬁ nger! Ensure that no other object can make contact with the driven components.

Never stand in the primary danger zone, i. e. in the rotational plane of the propeller or other rotating parts, when the motor is running or the drive battery is connected.

Please note that a glowplug engine or electric motor could burst into life accidentally if the receiving system is switched on when you are transmitting the transmitter. To be on the safe side, disconnect the fueltank or the ﬂ ight battery.

Protect all electronic equipment from dust, dirt, damp, and foreign bodies. Avoid subjecting the equipment to vibration and excessive heat or cold. Radio control equipment should only be used in “normal” ambient temperatures, i. e. within the range -15°C to +55°C.

Avoid subjecting the equipment to shock and pressure. Check the units at regular intervals for damage to cases and leads. Do not re-use any item which is damaged or has become wet, even after you have dried it out thoroughly.

Use only those components and accessories which we expressly recommend. Be sure to use only genuine matching GRAUPNER connectors of the same design with contacts of the same material.

When deploying cables ensure that they are not under strain, are not tightly bent (kinked) or broken. Avoid sharp edges, as they can chafe through insulating materials.

Before you use the system, check that all connectors are pushed home ﬁ rmly. When disconnecting components, pull on the connectors themselves – not on the wires.

It is not permissible to carry out any modiﬁ cations to the RC system components, as any such changes invalidate both your operating licence and your insurance cover.

Installing the receiving system and deploying the receiver aerial

In a model aircraft the receiver must be packed in soft foam and stowed behind a stout bulkhead, and in a model boat or car it should be protected effectively from dust and spray.

The receiver must not make direct contact with the fuselage, hull or chassis at any point, otherwise motor vibration and landing shocks will be transmitted directly to it. When installing the receiving system in a model with a glowplug or petrol engine, be sure to install all the components in well-protected positions, so that no exhaust gas or oil residues can reach the units and get inside them. This applies above all to the ON / OFF switch, which is usually installed in the outer skin of the model.

Secure the receiver in such a way that the aerial, servo leads and switch harness are not under any strain. The receiver aerial should be at least 5 cm away from all large metal parts and any wiring which is not connected directly to the receiver. This includes steel and carbon ﬁ bre components, servos, electric motors, fuel pumps, cabling of all kinds, etc..

Ideally the receiver should be installed well away from any other installed equipment in the model, but in an easily accessible position. Under no circumstances allow servo leads to run close to the aerial, far less coiled round it!

Ensure that cables are fastened securely, so that they cannot move close to the receiver aerial when the model is ﬂ ying.

The orientation of the aerial is not critical, but mounting it vertically inside the model is generally advantageous.

Installing the servos

Always install servos using the vibration-damping grommets supplied. The rubber grommets provide some degree of protection from mechanical shock and severe vibration.

Installing control linkages

The basic rule is that all linkages should be installed in such

Safety Notes

Please read carefully!

Safety Notes

mitters and any interference, and may respond. The model could then carry out uncontrolled movements, which could easily result in personal injury or damage to property.

Please take particular care if your model is ﬁ tted with a mechanical gyro: before you switch your receiver off, disconnect the power supply to ensure that the motor cannot run up to high speed accidentally.

As it runs down, the gyro can generate such a high voltage that the receiver picks up apparently valid throttle commands, and the motor could respond by unexpectedly bursting into life.

Range checking

Before every session check that the system works properly in all respects, and has adequate range. In this regard it is essential to read the notes on page 24 and the instructions supplied with the receiver you are using.

When operating a model, i. e. when ﬂ ying or driving, do not operate the transmitter without the aerial ﬁ tted. Check that the transmitter aerial is ﬁ rmly seated.

Operating your model aircraft, helicopter, boat or car

Never ﬂ y directly over spectators or other pilots, and take care at all times not to endanger people or animals. Keep well clear of high-tension overhead cables. Never operate your model boat close to locks and full-size vessels. Model cars should never be run on public streets or motorways, footpaths, public squares etc..

Checking the transmitter and receiver batteries

It is essential to stop using the radio control system and recharge the batteries well before they are completely discharged. In the case of the transmitter this means – at the very latest – when the message “battery needs charging” appears on the screen, and you hear an audible warning signal.

It is vital to check the state of the batteries at regular intervals – especially the receiver pack. When the battery is almost ﬂ at you may notice the servos running more slowly, but it is by no means safe to keep ﬂ ying or running your model until this happens. Always replace or recharge the batteries in good time.

Keep to the battery manufacturer’s instructions, and don’t leave the batteries on charge for longer than stated. Do not leave batteries on charge unsupervised.

Never attempt to recharge dry cells, as they may explode. Rechargeable batteries should always be recharged before

every session. When charging batteries it is important to avoid short-circuits. Do this by ﬁ rst connecting the banana plugs on the charge lead to the charger, taking care to maintain correct polarity. Only then connect the charge lead to the transmitter or receiver battery.

Disconnect all batteries and remove them from your model if you know you will not be using it in the near future.

Capacity and operating times

This rule applies to all forms of electrical power source: battery capacity is reduced every time you charge the pack. At low temperatures capacity is greatly reduced, i. e. operating times are shorter in cold conditions.

Frequent charging, and / or the use of maintenance programs, tends to cause a gradual reduction in battery capacity. We recommend that you check the capacity of all your rechargeable batteries at least every six months, and replace them if their performance has fallen off signiﬁ cantly.

Use only genuine GRAUPNER rechargeable batteries!

Suppressing electric motors

To a greater or lesser extent, all conventional electric motors produce sparks between commutator and brushes, depending on the motor type; the sparking generates serious interference to the radio control system. If an RC system is to

a way that the pushrods move accurately, smoothly and freely. It is particularly important that all servo output arms can move to their full extent without fouling or rubbing on anything, or being obstructed mechanically at any point in their travel.

It is essential that you should be able to stop your motor at any time. With a glow motor this is achieved by adjusting the throttle so that the barrel closes completely when you move the throttle stick and trim to their end-points.

Ensure that no metal parts are able to rub against each other, e. g. when controls are operated, when parts rotate, or when motor vibration affects the model. Metal-to-metal contact causes electrical “noise” which can interfere with the correct working of the receiver.

Directing the transmitter aerial

Transmitter ﬁ eld strength is at a minimum in an imaginary line extending straight out from the transmitter aerial. It is therefore fundamentally misguided to “point” the transmitter aerial at the model with the intention of obtaining good reception.

When several radio control systems are in use on adjacent channels, the pilots should always stand together in a loose group. Pilots who insist on standing away from the group endanger their own models as well as those of the other pilots.

Pre-ﬂ ight checking Before you switch on the receiver, ensure that the throttle

stick is at the stop / idle end-point.

Always switch on the transmitter ﬁ rst,

and only then the receiver.

Always switch off the receiver ﬁ rst,

and only then the transmitter.

If you do not keep to this sequence, i. e. if the receiver is at any time switched on when “its” transmitter is switched OFF, then the receiver is wide open to signals from other trans-

Safety Notes

work correctly, it is therefore important to suppress the electric motors, and in electric-powered models it is essential that every motor should be effectively suppressed. Suppressor ﬁ lters reliably eliminate such interference, and should always be ﬁ tted where possible.

Please read the notes and recommendations supplied by the motor manufacturer.

Refer to the main GRAUPNER FS catalogue or the Internet website at www.graupner.de for more information on suppressor ﬁ lters.

Servo suppressor ﬁ lter for extension leads

Order No. 1040 Servo suppressor ﬁ lters are required if you are obliged to use

long servo extension leads, as they eliminate the danger of de-tuning the receiver. The ﬁ lter is connected directly to the receiver input. In very difﬁ cult cases a second ﬁ lter can be used, positioned close to the servo.

Using electronic speed controllers

The basic rule is that the electronic speed controller must be chosen to suit the size of the electric motor it is required to control.

There is always a danger of overloading and possibly damaging the speed controller, but you can avoid this by ensuring that the controller’s current-handling capacity is at least half the motor’s maximum stall current.

Particular care is called for if you are using a “hot” (i. e. upgrade) motor, as any low-turn motor (small number of turns on the winding) can draw many times its nominal current when stalled, and the high current will then burn out the speed controller.

Electrical ignition systems

Ignition systems for internal combustion engines can also produce interference, which has an adverse effect on the working of the radio control system.

Electrical ignition systems should always be powered by a separate battery – not the receiver battery.

Be sure to use effectively suppressed spark plugs and plug caps, and shielded ignition leads.

Keep the receiving system an adequate distance away from the ignition system.

Static charges

Lightning causes magnetic shock waves which can interfere with the operation of a radio control transmitter even if the thunderstorm actually occurs several kilometres away. For this reason …

… cease ﬂ ying operations immediately if you notice an electrical storm approaching. Static charges through the transmitter aerial can be life-threatening!

Caution

In order to fulﬁ l the FCC RF radiation regulations appli-• cable to mobile transmitting apparatus, the equipment’s aerial must be at least 20 cm from any person when the system is in use. We therefore do not recommend using the equipment at a closer range than 20 cm.

Ensure that no other transmitter is closer than 20 cm from • your equipment, in order to avoid adverse effects on the system’s electrical characteristics and radiation pattern.

Before you use the radio control system, the receiver • must be programmed correctly to suit the country in which you are operating. This is essential in order to fulﬁ l various FCC, ETSI and IC directives. Please refer to the instructions provided with your receiver.

The receiver included with the system is set up at the factory for use in most European countries.

Never attempt to program the transmitter RF module • whilst you are operating a model. For the same reason do not touch any of the programming buttons on the RF module at such times.

Care and maintenance

Don’t use cleaning agents, petrol, water or other solvents to clean your equipment. If the case, the aerial etc. gets dirty, simply wipe the surfaces clean with a soft dry cloth.

Components and accessories

As manufacturers, the company of GRAUPNER GmbH & Co. KG recommends the exclusive use of components and accessories which have been tested by GRAUPNER and ap- proved for their capability, function and safety. If you observe this rule, GRAUPNER accepts responsibility for the product.

GRAUPNER cannot accept liability for non-approved components or accessories made by other manufacturers. It is not possible for GRAUPNER to assess every individual item manufactured by other companies, so we are unable to state whether such parts can be used without incurring a safety risk.

Liability exclusion / Compensation

We at GRAUPNER are unable to ensure that you observe the operating instructions, and are not in a position to inﬂ uence the way you install, operate and maintain the radio control system components. For this reason we are obliged to refute all liability for loss, damage or costs which are incurred due to the incompetent or incorrect use and operation of our products, or which are connected with such operation in any way.

Unless otherwise prescribed by law, the obligation of the GRAUPNER company to pay compensation is limited to the invoice value of that quantity of GRAUPNER products which was immediately and directly involved in the event in which the damage occurred. This does not apply if GRAUPNER is found to be subject to unlimited liability according to binding legal regulation on account of deliberate or gross negligence.

Introduction

mx-16 – the latest generation of radio control technology

2.4 GHz iFS technology (iFS = intelligent Frequency Select) with bi-directional communication between transmitter and receiver represents a further milestone in radio control technology. Several years of development and a comprehensive programme of testing have led to the introduction of this new Graupner | iFS system. The development phase was accompanied by intensive practical testing which has conﬁ rmed the many advantages of the overall design.

The Graupner/JR

mc-24 computer radio control system

was introduced back in 1997, and the mx-16iFS retains many of its features, reﬁ ned to meet the needs of the beginner. Although the mx-16iFS is intended primarily for the inexperienced user, it is still capable of controlling all current types of model, from ﬁ xed-wing model aeroplanes and helicopters to model boats and cars.

In the area of ﬁ xed-wing models and helicopters it is often necessary to employ complex mixer functions for the control surfaces or the swashplate actuation system. Computer technology enables you to activate a vast range of functions to cope with special model requirements – just by pressing a button. With the

mx-16iFS

all you do is select the appropriate model type, and the software then presents you automatically with the appropriate mixer and coupling functions. This means that the transmitter requires no additional modules in order to implement complex coupled functions, and you can forget all about old-fashioned mechanical mixers in the model. The mx-16iFS provides an extremely high level of safety and reliability in use.

The

mx-16iFS offers twelve model memories, each of

which can store model settings for different ﬂ ight phases. Individual phases can be called up in ﬂ ight simply by operating a switch, so that you can try out various settings

quickly and without risk. This can be for test purposes or for varying parameters for different phases of ﬂ ight.

The large graphic screen makes operating the transmitter a simple, intuitive process. Mixers and other functions can be displayed in graphic form, and this is extraordinarily helpful.

The beginner soon becomes familiar with the wide range of functions available thanks to the clear, logically arranged program structure. Adjustments are made using just three buttons on the left, together with the rotary cylinder to the right of the high-contrast screen, and in this way you very quickly learn how to make full use of all the options you need, according to your experience in handling radio-controlled models.

The digital modulation of the “intelligent frequency select” process provides the extremely high servo travel resolution of 65,536 steps, guaranteeing ultra-ﬁ ne control. In theory the Graupner | iFS system permits the simultaneous use of up to 120 models, although in practice the mixed operation of different technical systems in the 2.4 GHz band – as required by the approval regulations – reduces this number considerably. Generally, however, it will always be possible to operate even more models simultaneously on the 2.4 GHz band than on the 35 / 40 MHz frequency bands which we have used to date. However, the actual limiting factor – as it has always been – is likely to remain the size of the (air-) space available. The simple fact that no frequency control procedure is necessary equates to an enormous gain in safety, especially at ﬂ ying sites such as gliding slopes where groups of pilots may be distributed over a large area, with nobody in overall control.

The XZ-P1 iFS programming module, which is available as an optional accessory, provides a simple method of

programming the iFS RF transmitter module and the iFS receiver using a PC. Variable parameters include the output power of the RF module, the receiver output sequence and the Fail-Safe settings for each channel. Alternatively these functions can be programmed using push-buttons.

This manual describes each menu in detail, and also provides dozens of useful tips, notes and programming examples to complement the basic information. More general modelling terms, such as Transmitter controls, Dual-Rates, Butterﬂ y (Crow) and many others, are all explained in the manual.

The Appendix contains comprehensive information on the Trainer (teacher / pupil) system. The manual concludes with a table of the transmitter output powers and national receiver settings approved for use in individual European countries, copies of the Conformity Declaration and the transmitter’s Guarantee Certiﬁ cate.

Please read the safety notes and the technical information. We recommend that you read right through the instructions with great care, and check all the functions as described in the text. This can be carried out simply by connecting servos to the supplied receiver, and watching their response as you program the transmitter. This is the quickest method of becoming familiar with the essential procedures and functions of the

mx-16iFS.

Always handle your radio-controlled model with a responsible attitude to avoid endangering yourself and others.

All of us in the GRAUPNER team wish you every success and many years of pleasure with your

mx-16iFS, which

is an excellent example of the latest generation of radio control systems.

Operating Notes

Transmitter power supply

The

mx-16iFS transmitter is ﬁ tted as standard with a

high-capacity 8NH-2000 TX NiMH battery (Order No.

2498.8TX) (type may differ). When delivered, the standard rechargeable battery is not charged.

When you are using the transmitter you can monitor the battery voltage on the LCD screen. If the voltage of the transmitter battery falls below a certain point, you will hear an audible warning signal. The screen then displays a message reminding you that the transmitter battery needs to be recharged.

battery needs charging

Always recharge the transmitter battery in good time. When you see this message, cease operations immediately and recharge the transmitter battery.

Charging the transmitter battery

The rechargeable transmitter battery can be charged via the charge socket ﬁ tted to the right-hand side of the case. Leave the battery inside the transmitter for charging, to avoid premature damage to the internal battery socket.

The transmitter must be switched “OFF” for the whole period of the charge process. Never switch on the transmitter when it is still connected to the charger; even a very brief interruption in the process can cause the charge voltage to rise to the point where the transmitter is immediately damaged. For this reason check carefully that all connectors are secure, and are making really good contact.

Polarity of the

mx-16iFS charge socket

Commercially available battery charge leads produced by other manufacturers are often made up with the opposite polarity. For this reason use genuine GRAUPNER charge leads exclusively.

Charging the transmitter battery using an automatic charger

The transmitter is designed as standard for use with automatic battery chargers. However, this requires care on your part:

The transmitter charge socket is not protected against short-circuit and / or reversed polarity. It is therefore essential to use the correct procedure when connecting the charge lead: ﬁ rst connect the banana plugs on the charge lead to the charger, and only then connect the other end of the lead to the transmitter charge socket. When the charge lead is connected to the transmitter, never allow the bare ends of the plugs to touch! To avoid damage to the transmitter, the charge current must never exceed 1 A. If necessary, limit the current on the charger itself.

Charging the transmitter battery using a standard charger

It is also possible to charge the transmitter battery using a charger with no automatic termination (cut-off) circuit. The basic rule in this case is to charge the battery for fourteen hours, assuming that it is initially ﬂ at. The charge current should be one tenth of the capacity printed on the battery. This means 200 mA for the standard transmitter battery. However, you are responsible for terminating the charge process manually if you use a standard charger …

Removing the transmitter battery

The ﬁ rst step in removing the transmitter battery is to open the battery compartment cover in the back of the case. This is accomplished by pushing it in the direction of the arrow; it can then be lifted off:

Disconnect the plug at the end of the transmitter battery lead by pulling carefully on the lead, or by engaging a ﬁ nger nail behind the lug on the top of the connector. However, don’t pull the plug down or up; keep it as parallel as possible to the surface of the transmitter.

Battery timer, bottom left corner of the screen

This timer displays the cumulative operating time of the transmitter since the last time the transmitter battery was charged.

This timer is automatically reset to “0:00” when the transmitter detects that the voltage of the transmitter battery is signiﬁ cantly higher than the last time it was switched on, e. g. as a result of a charge process.

Operating Notes

Receiver power supply

A wide range of rechargeable four-cell and ﬁ ve-cell NiMH batteries varying in capacity is available for use as the receiver power supply. If you are using digital servos we recommend that you use a ﬁ ve-cell (6 V) pack of generous capacity. If your model is ﬁ tted with a mixture of digital and analogue servos, it is important to check the maximum permissible operating voltage of all the types.

The PRX unit, Order No. 4136, provides a stabilised receiver power supply with a user-variable voltage from one or two receiver batteries; see Appendix.

For reasons of safety battery boxes or dry cells should never be used.

For this reason you should make it a standard part of your routine to check the state of your batteries at regular intervals. Don’t wait until you notice the servos running more slowly than usual before recharging the packs.

Note: Please refer to the main GRAUPNER FS catalogue or visit the Internet site at www.graupner.de for full details of batteries, chargers, measuring equipment and battery monitor units.

Charging the receiver battery

The charge lead, Order No. 3021, can be connected directly to the NC receiver battery for charging. If the battery is installed in a model and you have installed one of the following switch harnesses: Order No. 3046, 3934 or 3934.1 or 3934.3, the battery can be charged via the separate charge socket, or the charge socket which is built into the switch. The switch on the switch harness must be left at the “OFF” position for charging..

General notes on battery charging

Observe the recommendations provided by the • charger manufacturer and the battery manufacturer at all times.

Keep to the maximum permissible charge current • stated by the battery manufacturer.

The maximum charge current for the transmitter • battery is 1.5 A. Limit the charge current to this value on the charger.

If you wish to charge the transmitter battery at a • current higher than 1.5 A, you must ﬁ rst remove the pack from the transmitter, otherwise you risk damaging the circuit board through overloading the conductor tracks, and / or overheating the battery.

Carry out a series of test charges to ensure that the • automatic charge termination circuit works correctly with your battery. This applies in particular if you are using an automatic charger designed for NiCd batteries to recharge the standard NiMH battery.

You may need to adjust the Delta Peak trigger volt-• age, if your charger provides this option.

Do not discharge the battery or carry out a battery • maintenance program via the integral charge socket. The charge socket is not suitable for this application.

Always connect the charge lead to the charger ﬁ rst, • and only then to the transmitter or receiver battery. Observing this rule eliminates the danger of accidental short-circuits between the bare contacts of the charge lead plugs.

If the battery becomes hot when on charge, it is time • to check the pack’s condition. Replace it if necessary, or reduce the charge current.

Never leave batteries unsupervised when on • charge.

Disposing of dry cells and rechargeable batteries

Never dispose of exhausted batteries in the household refuse. As end-user you are legally required (by the “Battery Regulation”) to return old and exhausted batteries. They should and must be taken to your local toxic waste collection point so that the materials can be re-used or re-cycled. Alternatively they can also be returned to any retail outlet where batteries are sold.

Opening the transmitter case

Please read the following notes carefully before you open the transmitter. If you have no experience in such matters, we recommend that you ask your nearest GRAUPNER Service Centre to carry out the work for you.

The transmitter should only be opened in the following cases:

When a self-neutralising stick needs to be converted • to non-neutralising action, or a non-neutralising stick to a self-neutralising action.

If you wish to adjust the stick centring spring tension.•

Before opening the transmitter check that it is switched off (move Power switch to “OFF”).

There is no need to remove the transmitter battery. However, if you leave it in place be sure not to switch the transmitter on (“ON” position). If you wish to remove the transmitter battery, please read the section on page 10.

Locate the six recessed screws on the back on the transmitter, and undo them using a PH1-size crosspoint screwdriver (see drawing right). Hold the two case sections together with your hand, and turn the unit over to allow these six screws to fall out onto the table. Now carefully raise the case back and fold it open to the left, as if you were opening a book.

C A U T I O N A two-core lead connects the case back to the trans-

mitter electronics in the front section. Please take great care not to damage this cable!

Important:

Do not modify the transmitter circuit in any way, • as this invalidates your guarantee and ofﬁ cial ap-

proval for the system. Do not touch any part of the circuit boards with •

any metal object. Avoid touching the contacts with your ﬁ ngers.

Never switch the transmitter on while the case is • open.

Please note the following points when closing the transmitter:

Make sure that no cables are jammed between the • transmitter case sections when you close the back.

Ensure that the DSC socket engages in its mounting.• Check that the two case sections fit together flush all •

round before fitting the retaining screws. Never force the two case components together.

Fit the case screws in the existing threads, and tight-• en them gently. Over-tightening them will strip the threads in the plastic.

Operating Notes

Stick centring spring tension

The stick centring force can be adjusted to suit the pilot’s personal preference. The adjustment system is located adjacent to the stick centring spring. Rotate the adjuster screw using a cross-point screwdriver until the spring tension feels right to you:

Turn to the right = harder spring tension;• Turn to the left = softer spring tension.•

Changing the stick mode

Either or both sticks can be converted from self-neutralising to non self-neutralising action: start by opening the transmitter as described on the previous page.

The procedure for changing the default stick mode setting is as follows:

Use a pair of tweezers to disconnect the spring from 1. the centring lever on the stick whose mode you wish to change. If you are not sure, move the appropriate stick to make it obvious. Raise the lever and disconnect it.

Locate the ratchet spring and 2. ﬁ x it to the plastic pillar using the (black) self-tapping screw supplied. You can now set the strength of the ratchet spring on the side of the hexagonal bush by screwing the M3 screw in or out.

Check that the stick works as you 3. prefer, then close the transmitter case once more.

Resetting the spring to “self-neutralising” action

Open the transmitter as already described.

Disconnect and remove the ratchet spring: see pic-1. ture left.

Now re-connect the (previously removed) cen-2. tring spring to the side of the stick where the ratchet spring was located.

First loosen the stick centring spring adjuster screw 3. slightly – see picture right – and then draw a length of thin thread through the upper loop of the spring – but don’t tie it. Now use a pair of tweezers to connect the spring to the bottom loop of the adjustment system, and then engage the top end of the spring to the centring lever using the thread. Once the spring is correctly ﬁ tted, the thread can be removed again.

The tension of the stick centring spring can be ad-4. justed as described in the next section.

Direct Servo Control

The original function of this socket was for “Direct Servo Control”, and that’s why the abbreviation is still in use. However, for technical reasons “direct servo control” is no longer possible with iFS systems using the diagnosis lead.

The

mx-16iFS transmitter’s standard two-pole socket is

now used as a Trainer (buddy box) socket (Teacher or Pupil), and as an interface for ﬂ ight simulators.

For the DSC connection to work you must check the following:

Carry out any adjustments required in the appropri-1. ate menus:

See page 122 for information on setting up the

mx-

16iFS transmitter to work as part of a Trainer system. ALWAYS2. leave the transmitter’s On / Off switch in

the “OFF” position when using a ﬂ ight simulator and when using the transmitter as a Pupil unit in a Trainer system, for only in this position is the RF section of the transmitter module switched off (no RF signal) even when the DSC lead is plugged in. At the same time the transmitter’s current drain is reduced slightly.

Connect the appropriate two-pole barrel connec-3. tor to the DSC socket on the back of the transmitter (switched off).

This renders the transmitter ready for use, and the LCD screen operates. At the same time the letters “DSC” appear to the left of the “iFS” symbol on the screen.

The display is accurate, and covers the range -150% to +150% of normal travel. 0% means the exact centre position. This allows you to check your settings quickly without even having to switch the receiver on. However, this does not mean that you don’t need to bother checking all the programming steps on the model; you must do this carefully before operating it for the ﬁ rst time, as this is the only reliable method of picking up and correcting errors.

The same applies if you use the receiver interchange facility (see page 26, or the instructions supplied with the receiver).

Using the transmitter for the ﬁ rst time

Preliminary notes

In theory the Graupner | iFS system permits the simultaneous use of up to 120 models, although in practice the mixed operation of different technical systems in the 2.4 GHz band – as required by the approval regulations – reduces this number considerably. Generally, however, it will always be possible to operate even more models simultaneously on the 2.4 GHz band than on the 35 / 40 MHz frequency bands which we have used to date. However, the actual limiting factor – as it has always been – is likely to remain the size of the (air-) space available. The simple fact that no frequency control procedure is necessary – a great convenience in itself – equates to an enormous gain in safety, especially at ﬂ ying sites where groups of pilots may be distributed over a large area, with nobody in overall control.

Battery charged?

When you take receipt of your transmitter, the battery will be in the discharged state, so you must ﬁ rst charge it as described on pages 10 / 11. If you do not do this, the battery will soon fall below the pre-set threshold voltage, and you will see and hear a warning signal to remind you to recharge it.

Aerial ﬁ tted?

For normal operations (ﬂ ying or driving a model) ensure that the iFS aerial is screwed in place and ﬁ rmly seated. However, hand-tight is quite sufﬁ cient – don’t use a tool!

Switching the transmitter on

When you switch the transmitter on, the Status LED on the Graupner | iFS RF module (on the back of the transmitter) brieﬂ y lights up orange, then red for a second before it starts ﬂ ashing red. Red ﬂ ashes mean that there is no connection with a Graupner | iFS receiver. When the connection is made, the Status LED constantly ﬂ ashes green.

The receiver supplied in the set is bound to the transmitter at the f

actory; the mx-16iFS transmitter can operate

up to eight servos in conjunction with this unit.

If telemetry sensors are connected to the receiver, the Status LED ﬂ

ashes orange when telemetry data is

received (this function is in preparation).

IMPORTANT NOTE:

In the interest of maximum possible ﬂ exibility, • control channels 5 … 8 are not assigned to transmitter controls by default; this also helps to eliminate the danger of inadvertently using them incorrectly. For the same reason virtually all the mixers are inactive by default. This means that in its standard form the transmitter can only control servos connected to receiver output sockets 1 … 4 using the primary dual-axis sticks. In contrast, any servos connected to receiver sockets 5 … max. 8 remain ﬁ xed at their centre position. This situation only changes when you have assigned a control element to the desired control functions 5 … 8 in the »contr set.« menu; see page 58 or 60.

The basic procedure for programming a new • model memory can be found on page 42, and in the programming examples starting on page 96.

Using the transmitter for the ﬁ rst time

Preliminary notes, programming the iFS RF module

For more information please visit the Internet site at www.graupner.de)

Expanded programming mode for the RF module

This mode enables the user to alter a number of characteristics and parameters. During this procedure

any Graupner | iFS receiver which has already been “bound” to the associated Graupner | iFS RF module MUST be switched off before the transmitter is switched on.

This is the procedure for switching to the expanded programming mode: locate the programming button on the RF module and hold it pressed in while you switch the transmitter on. Hold the button pressed in until the Status LED ﬁ rst goes out, then glows green and ﬁ nally glows a constant red (this process takes about seven seconds). Release the button: you are now in expanded programming mode.

Note: If the LED glows orange, you have held the button pressed in for too long. (In so doing you have activated a function which is intended for the X1-PZ iFS programming adapter.) If this should happen, repeat the procedure.

The individual set-up options can now be selected in sequence with brief presses of the programming button. The display of the Status LED changes in accordance with the following table. You can quit the “expanded programming mode” again at any time simply by switching the transmitter off.

Status LED Function

Constant RED Output power adjustment

Constant GREEN Hopping mode adjustment

(further set-up facilities are in preparation)

Using the transmitter for the ﬁ rst time

Setting the output power stage (value range: 1 … 5)

With the LED glowing a constant red, hold the programming button pressed in until the LED goes out. The LED now ﬂ ashes green slowly to indicate the currently set power output: 1 x ﬂ ash for stage 1, … 5 x ﬂ ash for stage

5. At the end of the ﬂ ashing sequence you can set a new value within a period of ﬁ ve seconds.

To change the output power, press the programming button brieﬂ y a speciﬁ c number of times, i. e. corresponding to the output power stage: one press for stage 1, … ﬁ ve presses for stage 5. As an example: if you wish to set the output power to the lowest value, you must press the programming button once brieﬂ y; if you wish to set output stage “3”, press the button three times in rapid succession. Every button-press is conﬁ rmed by the LED glowing red brieﬂ y.

If you do not press the programming button within ﬁ ve seconds, or if you enter an invalid value, the LED brieﬂ y ﬂ ashes alternately red / green (error indicator); in this case the set value is not altered. Once you have successfully set a new “value”, the LED conﬁ rms this by ﬂ ashing green / red / orange in rapid succession. In either case this procedure takes you back to the start of the expanded programming mode, where you can select the set-up options.

The power output stages stated in the table below MUST be observed, to ensure that the system fulﬁ ls the legal requirements of the country concerned:

Note:

The Status LED of Gr

aupner | iFS receivers glows • green in normal use if the output power is set to a stage higher than 1, and red if output stage 1 is set.

If you have set Hopping Mode 1 at the transmitter – • the default setting is “4” – then the green Status LED on the transmitter glows constantly, instead of ﬂ ashing as in modes 2 … 5.

Setting the Hopping Mode (Value range: 1 … 5)

With the LED glowing a constant green, hold the programming button pressed in until the LED goes out. The LED now ﬂ ashes green slowly to indicate the currently set Hopping stage. By default this is Hopping Mode 4, so the LED initially ﬂ ashes green four times.

At the end of the ﬂ ashing sequence you can set a new value within a period of ﬁ ve seconds. Press the programming button a speciﬁ c number of times, corresponding to the desired hopping mode. For example, to set Hopping Mode 3, you would now press the programming button three times.

Once you have successfully stored a new “value”, the

LED conﬁ rms this by ﬂ ashing green / red / orange in rapid succession.

CAUTION: The hopping information is transmitted during the binding process; see below. If you change the hopping mode or the output stage, you MUST then re-bind all your receivers.

Using the receiving system for the ﬁ rst time

Preliminary notes, programming the XR-16ifs receiver

(See also the instructions supplied with your particular receiver. For more information please visit the Internet site at www.graupner-ifs-system.de)

Receiving system

The

mx-16ifs radio control set includes an XR-16ifs 2.4

GHz bi-directional receiver which is suitable for connection to a maximum of eight servos.

When you switch the receiver on, its Status LED initially glows constantly for about three seconds, and then starts ﬂ ashing red. The latter means that no connection with a Graupner | iFS RF module exists (at this stage).

To be able to create a connection, the Graupner | iFS receiver must ﬁ rst be “bound” to “its” Graupner | iFS RF module (transmitter); this procedure is known as “binding”. However, binding is only necessary once for each receiver / RF module combination (and can be repeated whenever you wish – for instance, if you change the transmitter). The components in your system have already been bound at the factory.

The set you have purchased implements iFS Version 3, which differentiates between primary, subsidiary and supplementary receivers:

At the “Binding” stage – see below – receivers deﬁ ned as primary units can only be operated separately with a Graupner | iFS RF module. This eliminates the danger that a (primary) receiver in another model might respond to the same transmitter signal when it is switched on.

At the “Binding” stage – see below – receivers deﬁ ned as subsidiary units are operated in “Slave mode”, and are subordinate to the primary (“Master”) receiver. Subsidiary receivers can therefore be operated in parallel with primary receivers. They are intended primarily for use in large model aircraft, with the aim of avoiding long cable connections to the control surface servos, and the associated losses. A separate power supply can be used to prevent further unnecessary voltage drop. However, subsidiary receivers can also be employed at

completely different locations from the model, e. g. as monitor receivers on the ground.

The use of multiple receivers can also make sense in large model boats such as the Seabex One; with models such as the Adolph Bermpohl, Theodor Heuss or Bernhard Gruben ocean-going rescue cruisers the subsidiary receiver can be used to control the ship’s boat using one and the same transmitter.

The purpose of supplementary receivers (Order No. 23608, see Appendix) is quite different to that of subsidiary receivers: it is to enhance safety. For example, installing two supplementary receivers in the wingtips and another in the ﬁ n ensures that visual contact is maintained virtually constantly, with the result that at least one receiver can pick up the transmitter signal in any ﬂ ight attitude.

Note: The “programming button” referred to in the following sections is located on the circuit board, and can be operated using a blunt instrument such as a 1.5 mm allen key. PLEASE DO NOT USE A SCREWDRIVER to push the button, as the risk of damaging the circuit board is too great.

“Binding” the Graupner | iFS receiver

Graupner | iFS receivers must be “instructed” to communicate exclusively with a single Graupner | iFS RF module (transmitter). This procedure is termed “Binding”, and is only required once for each new receiver.

During this procedure any other Graupner | iFS main receiver MUST be switched off BEFORE you switch the transmitter on.

Now switch the Graupner | iFS receiver on, and wait until the status LED ﬂ ashes red. Hold the programming button on the receiver pressed in until its LED lights up green. Now release the programming button, and the Status LED will ﬂ ash orange, indicating that the receiver is now waiting for a Graupner | iFS transmitter to initiate the “binding” process.

At the transmitter end

Locate the Graupner | iFS RF module’s programming button on the back of the transmitter, and hold it pressed it while you switch the transmitter on. Hold the button pressed in while the Status LED ﬁ rst goes out, and then glows green, then release the programming button.

As soon as you release the programming button, the transmitter and receiver should bind together: all the Status LEDs will simultaneously switch to green if the binding process has been completed successfully. If one Status LED does not light up green, repeat the whole

procedure.

Binding subsidiary receivers

In Hopping Modes 2 … 5 any number of subsidiary receivers can be bound in common with a (single) primary receiver. (In contrast, multi-receiver operation is NOT possible with Hopping Mode 1.)

With the transmitter switched off, switch your subsidiary

Graupner | iFS receiver on. After a few seconds the Status LED starts ﬂ ashing red. Press and hold the program- ming button until the LED goes out, then glows green. Release the button at this point, and the Status LED will ﬂ ash orange.

Press and hold the programming button again until the Status LED changes from ﬂ ashing orange to constant orange, indicating that the receiver is now waiting to be “bound” as a subsidiary receiver. Leave the receiver switched on until the binding procedure is complete!

Repeat this procedure for as many subsidiary receivers as you wish to use. Please note that you must always have one primary receiver, and this is the last one to be set to binding mode; see left.

Caution:

The transmitter’s hopping mode and the output • stage MUST be deﬁ ned before you initiate the binding process – see previous double page!

To conclude the binding procedure switch off • the receiver(s) and also the transmitter, and leave them switched off for a few seconds before switching the transmitter back on, followed by the receiver(s). Your Graupner | iFS system is ready for use, BUT ONLY AFTER YOU SWITCH IT OFF, THEN ON AGAIN.

Always switch the transmitter on ﬁ rst, and only • then the receiver or receivers.

If a connection exists, the Status LED on the • transmitter RF module will glow a constant green, as will that of the receiver, provided that a power output stage between 2 … 5 has been set at the transmitter; it will glow red if the output power has been set to 1 - see earlier.

After switching the model off at the end of a ﬂ ight, • it is ESSENTIAL also to switch the transmitter off before another model can be operated; this is due to the “binding” process. For the same reason please ensure that your last model really is switched off before you switch the next model on.

This is the reason: if you have two or more receivers which are bound to the same transmitter module, and they are switched on simultaneously before the associated transmitter is switched on, “any” of the receivers will bind itself to the transmitter. Other receivers will not bind themselves unless they are conﬁ gured as subsidiary receivers; see above.

Range-checking

When using the Graupner | iFS system range checks should be carried out as described in the following paragraph. Ask a friend to help you when carrying out a range check.

Install the receiver in the model in the appropriate 1. manner, taking into account the information in the Installation Notes on page 30.

Install the antenna on the transmitter if not there.2. Turn on the radio system so servo movement can be 3.

observed. Using ﬂ at ground (pavement, low cut grass, or dirt) 4.

place the R/C device so that the receiver antenna is no less than 6” / 15 cm from the ground. This might require you elevating the R/C device during the testing.

Hold the transmitter at waist-height, away from your 5. body.

Press and 6. hold the programming button on the transmitter module.

Walk to a distance of at least 125 feet / 40 meters. If 7. at any time you experience a pause in controls, try to reproduce it again and release the button to see if the pause no longer occurs. If the problem does not occur now, check to make sure that your receiver is at least 6” / 15 cm from the ground while testing.

With the programming button still pressed down, walk 8. away from the R/C device while moving the sticks until there is intermittent control. If it does not respond 100% fully, do not use the system and contact Graup- ner GmbH & Co. KG for assistance!

If the model is powered, switch the power plant on 9. and check that it does not cause interference to the radio control system.

This completes the range test.10.

Note: In the case of “small” receivers, intended for use in model cars and / or park-ﬂ y model aircraft, you should carry out the check as described above, but at a range of about 25 m.

Caution: During normal operations (i. e. when controlling a model) never press and hold the programming button on the transmitter module!

Altering the servo outputs

The XR-16ifs receiver includes the option to assign the control channels to any receiver outputs you like. However, when using the receiver in conjunction with the

mx-16iFS transmitter, we recommend that you leave the

assignment at the 1 : 1 default setting, and if necessary make use of the “receiv out” option in the »base set.« menu.

Using the receiving system for the ﬁ rst time

National settings

Please ref

er to the instructions supplied with the receiver,

and the paragraph on page 126.

FAIL-SAFE settings

In its factory default state the receiver is set to maintain the servos at the last valid position detected by the receiver (“hold mode”) if a Fail-Safe event should occur. We strongly recommend that you make use of the system’s safety potential by programming the fail-safe throttle position of a glow-powered model to idle, or the throttle position of an electric-powered model to “motor stopped”. In this way you ensure that the model is much less likely to cause havoc if subjected to interference; if this should occur on the ground, the model could otherwise cause serious personal injury or damage to property.

A further option can be set which deﬁ nes the period (1 … max. 5 sec.) after which the Fail-Safe function is to become active.

The factory default setting is two seconds.

Low voltage warning

If the receiver LED glows orange, then the low voltage warning indicator is active. This means that the voltage is or was below about 4.4 V, although the collapse might have been brief due to a momentary heavy load.

Please ensure that the batteries are fully charged before you ﬂ y your model. Check that control surface linkages are free-moving; it is good practice to measure the voltage drop over the switch harness installed in the model.

Although the iFS system continues to work down to voltages below 3.5 V before it automatically restarts, the warning indicator should not be ignored, as in most cases it is a clear indication of a power supply which is not “ﬁ t for purpose”.

Safe model operation depends upon many factors, but one of them is certainly a reliable receiver power supply. If your model’s linkages are free-moving, the battery is fully charged, the conductors of the battery connecting leads are of adequate cross-section, the contact resistance at the connectors is minimal, etc., but the receiver LEDs insist on glowing a constant red (output stage 1) or green (output stages 2 … 5), then the servos are drawing an excessive current for the system. If this should occur, consider using a higher-capacity battery, perhaps with ﬁ ve cells, or the PRX stabilised receiver power supply, Order No. 4136, described in the Appendix.

Servo sockets and polarity

The servo sockets of the Graupner | iFS receiver are numbered. The socket marked “B/T” is intended for the battery, but also doubles as the data socket for the telemetry sensor.

Never connect this socket with reversed polarity! This would cause the receiver to switch itself on,

and appear to be working normally, but it would not function correctly!

The power supply voltage is through-connected via all the numbered sockets. The function of each individual channel is determined by the transmitter you are using, rather than by the receiver. Example: the throttle servo socket is deﬁ ned by the radio control system, and may differ according to the make and type. In the case of JR radio control systems the throttle function is assigned to channels 1 or 6, whereas it is allocated to channel 3 in the case of Futaba radio control systems.

Concluding notes:

The much higher servo resolution of the iFS system • results in a more direct response compared with previous technologies. Please take a little time to become accustomed to the feeling of ﬁ ner control!

If you wish to use a speed controller with integral • BEC* system in parallel with a separate receiver battery, in most cases (depending on the speed controller) the positive terminal (red wire) must be removed from the three-pin connector, as shown in the diagram. Be sure to read the appropriate notes in the instructions supplied with your speed controller before doing this.

Carefully raise the central lug of the connector slightly (1), withdraw the red wire (2) and insulate the bare contact with tape to avoid possible short circuits (3).

Observe the installation notes regarding the servos, receiver and receiver aerial, which you will ﬁ nd on page 30.

Expanded receiver programming mode

The expanded programming mode enables the user to alter various receiver characteristics and parameters. Always read the instructions supplied with your particular XR receiver before making any changes of this type! If necessary you can also ﬁ nd information on this subject in the Download area of our website at www. graupner.de.

Important note: For the procedure described in the following section it is ESSENTIAL to switch off every transmitter with a Graupner | iFS RF module to which the associated Graupner | iFS receiver has already been “bound”, before you switch the receiver on.

To enter expanded programming mode, ﬁ rst switch the receiver on and wait until the Status LED ﬂ ashes red at a moderate rhythm. Now use a blunt instrument – such as a 1.5 mm allen key – to hold the programming button on the receiver pressed in while the Status LED ﬁ rst goes out, then lights green, and ﬁ nally glows a constant red (the process takes about seven seconds). Now release the button.

As soon as the receiver is in expanded programming mode, the Status LED glows a constant red, as you are now automatically located at the ﬁ rst set-up option (see table below). The remaining set-up options can be selected in sequence with brief presses on the programming button. The display of the Status LED changes in accordance with the following table:

ting

Constant GREEN 2 National setting

Constant ORANGE 3 (This function is cur-

rently not used)

Rapid ﬂ ashing RED 4 Fail-Safe setting

Option 1: Assigning the control channels to the

receiver outputs

(value range: 1 … max. number of receiver channels)

Note: The Graupner | iFS receiver includes the option to assign the control channels to any receiver outputs you like. However, when using the receiver in conjunction with the

mx-16iFS transmitter, we recommend that you leave the

assignment at the 1 : 1 default setting, and if necessary make use of the “receiv out” option in the »base set.« menu; see pages 49 and 53.

With the Status LED glowing constant red – see above – press and hold the programming button until the LED goes out.

The LED now ﬂ ashes orange repeatedly, the number of ﬂ ashes corresponding to the number of servo sockets, followed by a one-second pause. After ﬁ rst selecting this set-up option (channel 1) the Status LED also ﬂ ashes once, followed by a one-second pause.

Every brief press on the programming button cycles through to the next servo output: this begins with 1 (1 x ﬂ ash) and ends with the number of channels of your receiver (“8” for an eight-channel receiver, ”10” for a tenchannel receiver, etc.).

To assign a different channel to the selected receiver output, press and hold the programming button until the Status LED goes out. The LED now ﬂ ashes green repeatedly, the number of ﬂ ashes corresponding to the number of the currently assigned channel.

When the Status LED has indicated the current assignment by ﬂ ashing green, you have a period of ﬁ ve sec- onds to enter a new assignment; this is accomplished by brieﬂ y pressing the programming button the appropriate number of times.

Note: For the control channel you can enter values within the range 1 to 16, even if the receiver features fewer servo sockets. For example, if you wish to use the

mx-16iFS

with a six-channel receiver, it is possible to assign control channel 7 or 8 to any of the otherwise unoccupied outputs 1 … 6.

If you do not press the programming button within the ﬁ ve-second period, or if the value you enter is higher than permissible, the LED ﬂ ashes alternately red and green (error indicator), and a new assignment is not carried out. You are then returned to the channel select point for the assignment process.

However, if a new assignment takes place successfully, the LED ﬂ ashes green / red / orange in rapid sequence, in order to indicate that the change has been implemented.

The option of assigning control channels to any receiver

Expanded receiver programming mode

outputs is very practical, especially if the transmitter only has limited functionality, or if you wish to re-direct channels to different outputs. The default setting is 1 : 1, i. e. the control channels are passed to the receiver outputs bearing the same number.

Instead of using a Y-lead you can also assign the same control function to two or more receiver outputs, e. g. “Throttle”, in order to operate two or more servos with one control function. For example, you could leave one servo at the “normal” output (e. g. for “throttle” control – channel 1 for ﬁ xed-wing models or channel 6 for model helicopters in the case of most Graupner/JR systems), and assign the second or subsequent servos to one or more of the higher-numbered outputs which are not used as standard. All the outputs are totally synchronised, i. e. the delay which is occasionally observed with earlier systems is entirely absent. Any servo adjustment which is carried out in the »servo set.« menu (see page

56), applies to all the servos set up in this way.

Option 2: National setting

(value range: 1 … 2)

This setting applies exclusively to Hopping Mode 1, and has no effect if any other hopping mode is selected. You can therefore skip the next section, provided that you have not changed the hopping mode from the default setting “4”.

The national setting is necessary in order to satisfy various directives (FCC, ETSI, IC, etc.). With the Status LED glowing a constant green – see table in the centre column on page 27 – press and hold the programming button until the LED goes out. The LED now ﬂ ashes green repeatedly, the number of ﬂ ashes corresponding to the code number of the set country. If the default

value (1) is set, the Status LED therefore ﬂ ashes once. When the ﬂ ashing stops, you have a ﬁ ve-second pe-

riod to change the country code. This is accomplished by pressing the programming button repeatedly, the number of presses corresponding to the codes stated in the table below.

Example: If the country is to be, say, France, press the pro-

gramming button twice brieﬂ y. If you do not press the programming button within ﬁ ve seconds, or if you enter a value which is higher than the permissible range, then the LED ﬂ ashes alternately red and green (error indicator), and no new national assignment is carried out; you are then returned to the select point for the programming options. However, if a change is carried out successfully, the LED ﬂ ashes green / red / orange in rapid sequence to conﬁ rm the successful operation.

Country Setting

All countries except France 1

France 2*

* Open-air operation. Transmitter power “1” or “2” must be selected.

Option 3: Output signal setting

This function is currently not supported. It is planned for future versions which will permit different methods of actuating servos, such as sequential, in groups, TruDigital™, etc..

Option 4: Fail-Safe settings

“hold” or “Pos” for channels

(value range: 1 … max. number of receiver outputs) In the receiver’s default state the servos maintain the

position last detected as valid (“hold”) when interference occurs, since this is the default setting for all channels.

As described in the following section, or in the instructions supplied with your particular receiver, it is also possible to set whether the channel maintains the last correctly received servo position if interference occurs (“hold”), or – after a period of time – takes up a position deﬁ ned using the next option; this can be set separately for each channel.

With the Status LED ﬂ ashing red at a rapid rhythm – see table in the centre column on page 27 – press and hold the programming button until the LED goes out. The LED then ﬂ ashes orange repeatedly, the number of ﬂ ashes corresponding to the number of servo outputs, followed by a one-second pause. After you initially select this set-up option (channel 1), the Status LED therefore ﬂ ashes once followed by a one-second pause.

Every brief press on the programming button cycles through the next servo output: this starts with 1 (1 x ﬂ ash) and ends with the number of channels your receiver supports, so that – for example – the Graup- ner | iFS eight-channel receiver offers eight possible set-up positions, whereas, for example, the Graupn- er | iFS ten-channel receiver features ten possible set-up positions.

In order to change the fail-safe setting of the selected receiver output, press and hold the programming button until the Status LED goes out. The LED then ﬂ ashes green, either once for “hold” or twice for “position”.

Once the Status LED has ﬂ ashed green to indicate the current setting, you have a period of ﬁ ve seconds to enter a new setting. This is accomplished by pressing the programming button brieﬂ y the appropriate number of times: once for “hold”, twice for “position”.

Expanded receiver programming mode

If you do not press the programming button within the ﬁ ve-second period, or if you enter an invalid number, then the LED ﬂ ashes alternately red and green (error indicator), and no new setting is adopted. You are then returned to the channel select point for this function. However, if a new setting is carried out successfully, the LED ﬂ ashes green / red / orange in rapid succession to indicate that the change of setting has been adopted.

The actual fail-safe positions for the selected channels can only be set later, after you have left expanded programming mode; see right-hand page.

Example: If you are programming a ﬁ xed-wing model aircraft and

wish to set the motor to “position”, whilst leaving all the other channels to “hold”, set channel 1 to 2 x ﬂ ashing, and leave all the other channels to 1 x ﬂ ashing.

The only way of quitting the fail-safe channel setting is to switch the receiver power supply off.

Option 5: Fail-safe setting – “hold time”

(value range: 1 … 5 seconds) The fail-safe time is the number of seconds in which

no valid control data is received, before the receiver switches to fail-safe or hold-mode.

When this “hold time” has elapsed, the receiver switches over to “fail-safe”: the channels programmed to “position” take up the prescribed fail-safe position, while the remaining channels maintain the position last picked up as valid (“hold”).

After selecting this set-up option (the LED ﬂ ashes green at a rapid rate – see table in the centre column of page

27) press and hold the programming button until the LED goes out. The LED now ﬂ ashes green repeatedly,

the number of ﬂ ashes corresponding to the number of seconds selected. For example, if the default value (2) is set, the Status LED ﬂ ashes twice.

After the Status LED has ﬂ ashed green to indicate the current setting, you have a period of ﬁ ve seconds to enter a new setting. This is accomplished by pressing the programming button brieﬂ y the appropriate number of times.

Example: If you want the fail-safe time to be one second, press

the programming button once brieﬂ y. For three seconds, press it three times brieﬂ y, etc..

Option 6: Telemetry setting

This option is currently at the development stage.

Quitting expanded programming mode

You can quit expanded programming mode at any time simply by switching off the receiver power supply.

Deﬁ ning Fail-Safe positions

Switch the transmitter and receiver on “normally”, and wait until you can control the servos with the sticks.

Press and hold the programming button on the Graup- ner | iFS receiver until the Status LED goes out. The indicator now starts to ﬂ ash alternately red and green for

a period of about eight seconds. Within this time you should move the sticks and other

transmitter controls – those that have already been deﬁ ned – to the positions which correspond to the servo settings in the model which you wish to adopt as the Fail-Safe positions; these settings are then stored in the receiver when the LED goes out.

Resetting the receiver to the default settings (RESET)

This reset procedure resets all the settings, including the binding settings. This means that the “binding” procedure must be repeated with this receiver and a Graup- ner | iFS transmitter module.

To carry out the reset hold the programming button pressed in while you switch the receiver on. As soon as the Status LED ﬂ ashes red, you can release the pro- gramming button.

This completes the reset.

Optional programming adapter: XZ-P1 iFS

Order No. 23300

This adapter, which is available as an optional accessory (see Appendix), is a convenient means of programming all the necessary settings in the iFS RF module and the iFS receiver using a PC and a wireless link.

To switch the receiver into computer programming mode, press and hold the programming button while you switch the receiver on. The Status LED will glow orange.

Installation Notes

chanical linkage can obstruct the servo in its movement.

The sequence in which the ser

vos are connected to the receiver is dictated by the model type. Please see the socket assignments listed on pages 37 / 38 and 41.

Be sure to read the safety notes on pages 3 … 5. If the receiver is ever switched on when the transmitter

is off, the servos may carry out uncontrolled movements. You can avoid this by switching the system on in this order:

Always switch the transmitter on ﬁ rst,

then the receiver.

When switching the system off:

Always switch the receiver off ﬁ rst,

then the transmitter.

When programming the transmitter you must always ensure that any electric motors in the system cannot possibly burst into life accidentally, and that an I. C. engine ﬁ tted with an automatic starter cannot start unintentionally. In the interests of safety it is always best to disconnect the ﬂ ight battery, or cut off the fuel supply.

The following section contains notes and helpful ideas on installing radio control components in the model:

Wrap the receiver in foam rubber at least 6 mm thick. 1. Fix the foam round the receiver using rubber bands, to protect it from vibration, hard landings and crash damage.

All switches must be installed in a position where 2. they will not be affected by exhaust gases or vibration. The switch toggle must be free to move over its full range of travel.

Always install servos using the vibration-damping 3. grommets and tubular metal spacers supplied. The rubber grommets provide some degree of protection from mechanical shock and severe vibration. Don’t over-tighten the servo retaining screws, as this will compress the grommets and thereby reduce the vibration protection they afford. The system offers good security and vibration protection for your servos, but only if the servo retaining screws are ﬁ tted and tightened properly. The drawing below shows how to install a servo correctly. The brass spacers should be pushed into the rubber grommets from the underside.

Installation Notes

Installing the receiver

Regardless of which Graupner | iFS receiver you are using, the procedure is always the same:

Please note that the receiver aerial must be arranged at least 5 cm away from all large metal parts and leads which are not attached or connected directly to the receiver. This includes steel and carbon ﬁ bre components, servos, fuel pumps, cables of all sorts, etc.. Ideally the receiver should be installed in an easily accessible position in the model, away from all other installed components. Under no circumstances run servo leads immediately adjacent to the receiver aerial, far less coil them round it!

Please note that acceleration forces which occur in ﬂ ight might cause cables to shift when the model is operating. For this reason ensure that all leads are prevented from moving close to the aerial. Moving connections or cables can cause interference to the system.

Tests have shown that a vertical (upright) installation of the aerial gives the best results during long approaches.

The servo sockets of Graupner | iFS receivers are numbered. The socket marked “B/T” is intended for the battery, but will also be used in future for the data connection of the telemetry sensor.

The power supply is through-connected using all the numbered receiver sockets.

The function of each individual channel is determined by the transmitter in use, rather than by the receiver. Please bear this in mind in particular if you wish to bind the receiver to a different make of transmitter ﬁ tted with a Graupner | iFS RF module.
