Safety Notes

Please read carefully!

We all want you to have many hours of pleasure in our

utual hobby of modelling, and safety is an important

m aspect of this. It is absolutely essential that you read right through these instructions and take careful note of all our safety recommendations. We also strongly recommend that you register without delay at http:// www.graupner.de/en/service/product_registration, as this ensures that you automatically receive the latest information relating to your product by e-mail.

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 hu- mans. 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 gearboxes 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

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

Safety Notes

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.

Deploying the receiver aerial(s)

The receiver and its aerials should be installed as far away as possible from all kinds of power system. If your model has a carbon ﬁ bre fuselage, the aerial tips must always be deployed outside the fuselage. The orientation of the aerial(s) is not critical, but we recommend installing them vertically (upright) in the model. If the receiver features aerial diversity (two aerials), the second aerial should be arranged at 90° to the ﬁ rst.

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 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. Metalto-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.

However, if two or more pilots operating 2.4 GHz radio control systems stand closer together than 5 m, the down-link channel may be swamped, triggering a very premature range warning. If this should occur, walk away from the other pilots until the range warning ceases again.

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

tle 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 transmitters 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.

adequately, and ensure that no persons are standing in front of the model.

Carry out at least one complete function check on the ground, followed by a complete simulated ﬂ ight, in order to show up any errors in the system and the model’s programming. Be sure to read the notes on pages 62 and 71 in this regard.

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..

Secure the model

Safety Notes

Checking the transmitter and receiver batteries

It is essential to stop using the r

adio 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 battery types: capacity diminishes with each charge. At low temperatures the battery’s internal resistance rises, and capacity falls. This means that its ability to deliver current and maintain voltage is reduced.

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

All conventional (brushed) electric motors generate sparks between the commutator and the brushes, which cause more or less serious interference to the radio control system, depending on the type of motor. If an RC system is to 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!

Safety Notes

applicable to mobile transmitting apparatus, the equipment’ 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.

The radio control system should not be operated • until the Country setting has been set correctly at the transmitter. This is essential in order to fulﬁ l the requirements of various directives - FCC, ETSI, CE etc. Please refer to the instructions for your particular transmitter and receiver for details of this procedure.

Check all working systems and carry out at least one • full range check on the ground before every ﬂ ight, in order to show up any errors in the system and the model’s programming.

Never make any changes to the programming of the • transmitter or receiver whilst operating a model.

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.

Safety notes and handling instructions relating to Nickel-Metal-Hydride rechargeable batteries

As with all sophisticated technical products, it is vitally important that you observe the following safety notes and handling instructions if you wish the equipment to operate safely and reliably for an extended period.

Safety notes

Rechargeable batteries are not playthings, and must • be kept well away from children.

Store rechargeable batteries out of the reach of children.

Check that the batteries are in perfect, serviceable • condition before every use. Do not re-use defective or damaged batteries.

Rechargeable batteries must be used within the • speciﬁ ed limits stated for the corresponding cell type.

Do not heat, incinerate or short-circuit rechargea-• ble batteries, and never charge them with excessive currents or reversed polarity.

Never use rechargeable batteries consisting of • parallel-wired cells, combinations of old and new cells, cells of different construction, size, capacity, make, brand or cell type.

Batteries installed inside equipment should always be • removed from the device when it is not in use and not about to be used. Always keep equipment switched off in order to avoid deep-discharged cells. Batteries must be recharged in good time.

The battery to be charged should be placed on a • non-inﬂ ammable, heat-resistant, non-conductive surface for the whole of the charge period. Keep inﬂ ammable and volatile objects and materials well clear of the charging area.

Batteries must always be supervised when on • charge. Never exceed the maximum fast-charge cur-

Safety Notes

rent speciﬁ ed for the cell type in use. If the battery heats up to more than 60°C whilst on •

charge, halt the charge process immediately and allow the pack to cool down to about 30°C.

Never recharge a battery which is already charged, • hot, or not completely discharged.

Do not make any modiﬁ cations to batteries. Never • solder or weld directly to cells.

If incorrectly handled, rechargeable batteries are at • risk of combustion, explosion, corrosive action and burns. Suitable extinguishing materials include ﬁ re blankets, CO2 ﬁ re extinguishers and sand.

Escaped electrolyte is corrosive - do not allow it to • contact skin or eyes. In an emergency rinse the area immediately with plenty of clean water before seeking medical help.

The cells’ air vents must never be blocked or sealed, • e. g. by solder. When soldering, the iron temperature should not exceed 220°C, and each joint should be completed in less than twenty seconds.

To avoid cell deformation, do not exert excessive • mechanical pressure on battery cells.

If a battery should be accidentally overcharged, use • the following procedure:

Simply disconnect the battery and leave it on a noninﬂ ammable surface (e. g. stone ﬂ oor) until it has cooled down. Never hold the battery in your hand, as there is a risk that cells might explode.

Always observe the recommended rates for charging • and discharging.

General information

The capacity of your rechargeable battery diminishes with every charge / discharge process. Stored batteries

may eventually exhibit reduced capacity.

Storage

Batteries should not be stored in a completely discharged state. Store them in a dry enclosed space at an ambient temperature of +5°C to +25°C. If you are storing a battery for a period longer than four weeks, ensure that the cell voltage does not fall below 1.2 V

Balancing individual battery cells

To balance new battery cells, i. e. to bring them all • to the same state of charge, charge them at what is known as the ‘normal’ rate until they are full. As a general guideline a fully discharged battery needs to be charged for a period of twelve hours at a current corresponding to one tenth of the capacity printed on the cell label (the “1/10C” method). After this treatment all the cells will be fully charged, and exhibit the same voltage. This method of balancing battery cells should be repeated after every ten fast-charge processes, so that the cells are repeatedly balanced; this helps to ensure an extended useful life for your batteries.

If you have the facilities to discharge individual cells, • we recommend that you make use of this before every charge process. Otherwise the battery pack should be run down to a discharge voltage of 0.9 V per cell. For example, this corresponds to a ﬁ nal discharge voltage of 3.6 V in the case of the four-cell pack used in the transmitter.

Charging

Ni-MH batteries should only be charged using the speciﬁ ed currents, charge times and temperature range, and should be supervised constantly when on charge. If you do not have access to a suitable fast charger, i. e. one

33112_mx12_HoTT_2_GB.indd Abs57:833112_mx12_HoTT_2_GB.indd Abs57:8 06.06.2011 19:39:2506.06.2011 19:39:25

which allows you to set the charge current accurately, then the batter

y should always be recharged using the “normal” charge rate of 1/10C; see the example stated above.

Wherever possible, transmitter batteries should always be recharged at the 1/10C rate, in order to avoid differences in cell states. The charge current must never exceed the maximum permissible value stated in the transmitter instructions.

Fast charging

If your battery charger includes the facility to adjust • the Delta Peak charge cut-off voltage, set this value to 5 mV per cell. However, most chargers are set to a ﬁ xed cut-off value of 15 … 20 mV per cell, which makes them suitable for use with both NiCd and NiMH batteries. If you are not sure about this, please refer to the operating instructions supplied with your charger, or ask at your local model shop whether your charger is also suitable for Ni-MH packs. If in any doubt, charge your batteries at half the stated maximum charge current.

Discharging

All rechargeable batteries sold by Graupner and GMRacing are suitable for a maximum continuous current load of 6C … 13C, according to battery type (refer to the manufacturer’s speciﬁ cation!). The higher the continuous current load, the shorter the batteries’ useful life.

Use your battery until its performance falls off, or until • the low voltage warning is triggered.

Caution:

When stored for a long period, the cell voltage should not be allowed to fall below 1.2 V. This means that you may have to recharge the battery before stor-

ing it. Reﬂ ex charging and charge / discharge (cycle) •

programs shorten the effective life of batteries unnecessarily, and are only suitable for checking battery quality or “reviving” relatively old cells. It also makes no sense to charge / discharge a battery before using it - unless you simply wish to check its quality.

Disposal of exhausted dry and rechargeable batteries

The German Battery Order places a legal requirement on every consumer to return all used and exhausted dry cells and rechargeable batteries. It is prohibited to dispose of these items in the ordinary domestic waste. At no charge to the user, old dry and rechargeable batteries can be surrendered at local authority collection points, Graupner retail outlets, and any other shop where dry and rechargeable batteries of the same type are sold. You can also send batteries supplied by us to the following address - with adequate pre-paid postage

mx-12 the latest generation of radio control technology

HoTT (Hopping Telemetry Transmission) is the synthesis of expertise, engineering and world-wide testing by professional pilots. The equipment operates on the 2.4 GHz band, and offers bi-directional communication between transmitter and receiver via a down-link channel integrated into the receiver.

The mx-12 HoTT RC system is based on the Graup- ner/JR mc-24 computer radio control system which was introduced back in 1997. It has been developed speciﬁ cally for the beginner, but the mx-12 HoTT is still capable of controlling all current model types without problem - whether ﬁ xed-wing model or helicopter, model boat or car.

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- 12 HoTT 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-12 HoTT provides an extremely high level of safety and reliability in use.

The mx-12 HoTT offers ten 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 quickly becomes familiar with the different functions thanks to the clear, logically arranged program structure. Four-way buttons to left and right of the highcontrast screen are used to enter settings, allowing the user to exploit all the options he needs, in accordance with his experience in handling radio-controlled models.

In theory the Graupner HoTT process allows more than 200 models to be operated simultaneously. Although in practice the mixed operation of different technical systems in the 2.4 GHz ISM 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 integral Telemetry menu provides a simple means of accessing data and programming HoTT receivers. For example, this method can be used to map receiver outputs, distribute control functions to multiple servos, and match servo travels and directions to each other.

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.

Please refer to the Appendix for additional information on the HoTT system. This manual concludes with the transmitter’s conformity declaration and 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. However, please read the notes on page 20 in this regard. This is the quickest method of becoming familiar with the essential procedures and functions of the mx- 12 HoTT.

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

The Graupner team wishes you great pleasure and success with your mx-12 HoTT - a radio control system of the latest generation.

Transmitter power supply

The mx-12 HoTT transmitter is ﬁ tted as standard with a high-capacity rechargeable 4NH-2000 RX RTU Ni-MH battery (Order No. 2498.4FBEC) (speciﬁ cation reserved). 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.

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 Ni-MH transmitter battery can be recharged with the battery charger (Order No. 33116.2) supplied in the set, using the charge socket located on the right-hand side of the transmitter. Leave the battery inside the transmitter for charging, to avoid premature damage to the internal battery socket.

As an approximate guideline a discharged battery should be charged for twelve hours at a current corresponding to one tenth of the capacity printed on the pack. If you are using the standard transmitter battery and the charger supplied in the set, this current is

Operating Notes

200 mA. 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-12 HoTT charge socket

Commercially available battery charge leads produced by other manufacturers are often made up with the opposite polarity. For this reason it is essential to use only the genuine Graupner charge lead, Order No. 3022.

Using automatic battery chargers

Although the standard transmitter charge socket is protected against reversed polarity, it is still possible to use suitable chargers to fast-charge the transmitter battery.

If possible, set the delta peak voltage difference of your fast charger to a value in the range 10 mV … 20 mV or equivalent, as described in the charger’s instructions; this ensures that it is suitable for fast-charging Ni-MH cells.

First connect the banana plugs on the charge lead to the charger, and only then connect the other end of the charge lead to the charge socket on the transmitter. 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.

Removing the transmitter battery

To remove the transmitter battery, ﬁ rst disengage the cover over the battery compartment on the back of the transmitter, then lift it off:

Remove the battery, then carefully pull on the power lead to disconnect the transmitter battery connector.

Installing the transmitter battery

Hold the connector attached to the transmitter battery in such a way that the black or brown wire faces the aerial, and the unused socket of the battery connector is on the side facing the bottom, then push the battery connector onto the three pins projecting out of the inside of the transmitter, in the direction of the circuit board. (The battery connector is protected against reversed polarity by two chamfered edges; see illustration).

Finally place the battery in the compartment, and close the cover.

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.

The voltage of the airborne power supply is displayed on the transmitter screen while the model is ﬂ ying:

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 wish to charge the standard Ni-MH battery using an automatic charger designed for Ni-Cd batteries.

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.

Now screw the stick top in or out (shorter or longer) to the length you prefer before tightening the top and bottom sections against each other to ﬁ x the stick top.

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”).

Open the battery compartment and remove the transmitter battery as described on the previous double page, together with any micro-SD card already installed.

After this, use a PH1-size cross-point screwdriver to undo the six screws recessed into the back panel of the transmitter, as shown in the illustration:

Arrangement of the case back screws

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 right, as if you were opening a book.

C A U T I O N

Two multi-core cables connect the lower shell to the transmitter electronics located in the top 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 approval 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.

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.

Remember to re-connect the battery.•

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 the HoTT system using a diagnosis lead.

The mx-12 HoTT transmitter’s standard two-pole DSC 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 134 for information on setting up the mx- 12 HoTT 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 mx-12 HoTT transmitter as a Pu- pil 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.

The central Status LED should now glow a constant red, and the abbreviation “DSC” appears in the transmitter’s base display on the left, below the model number. At the same time the display of telemetry symbols is suppressed:

In contr Teacher mode, the transmitter must be switched on before the appropriate cable is plugged in.

Connect the other end of the connecting lead to the 3. appropriate apparatus, taking into account the operating instructions supplied with that device.

Important:

Ensure that all connectors are ﬁ rmly seated in their sockets.

Note regarding ﬂ ight simulators: The range of ﬂ ight simulators available commercially is now very wide, and you may ﬁ nd that it is necessary to swap over certain contacts at the barrel connector or the DSC module. This work must be carried out by a Graupner Service Centre.

Data storage

Card slot

micro-SD and micro-SDHC When you switch off the mx-12 HoTT transmitter and

remove the battery compartment cover, you will see the card slot for memory cards (of the micro-SD and microSDHC type) in the right-hand side of the compartment:

Any standard commercial micro-SD memory card with a capacity of up to 2 GB can be used, and also any microSDHC card of up to 32 GB. However, the manufacturer recommends the use of memory cards with capacities up to only 4 GB, as these are completely adequate in all normal circumstances.

The memory cards for which the transmitter is intended are familiar from their use in digital cameras and mobile telephones. Place the card in the slot with the contacts facing up, towards the back panel, and push it in until it locks. Re-install the battery and close the battery compartment; the transmitter can now be switched on again. The base display shows a stylised memory card symbol to indicate that a memory card is present:

Note: If there is an SD card installed, withdraw it BEFORE you remove the transmitter’s back panel, otherwise there is a risk that you will damage the card.

Data recording / storage

The process of saving data on the SD card is coupled to the ﬂ ight timer: if the timer is started, then data saving commences - provided that a suitable memory card is in the card slot, and a telemetry connection to the receiver exists - and ceases again when the ﬂ ight timer is stopped. The ﬂ ight timer is started and stopped as described in the “Timers” section on page 59 for ﬁ xed-wing models, and pages 67 and 68 for model helicopters.

When data is being recorded, the card symbol ﬂ ashes constantly and slowly.

When data is being written to the memory card, the memory card symbol swells from left to right to indicate the process.

When a data storage process is concluded, you will ﬁ nd an (empty) “Models” folder and a “Log-Data” folder on the memory card. The latter contains the log ﬁ les, stored in sub-folders named “Model name”, using the format

0001.bin, 0002.bin etc. However, if a model memory has not yet been named, then you will ﬁ nd the associated log ﬁ les in a sub-folder named “NoName” when you remove the memory card from the transmitter and

insert it in the card slot of a PC or laptop. If you wish, the standard - ﬁ xed - date of creation can be changed on the PC using a suitable program, and the data can subsequently be analysed on a compatible PC using the PC program available on the Download page for the transmitter at www.graupner.de.

Importing voice ﬁ les

As mentioned in the section entitled “Optional headphone socket” on page 21, signals and messages associated with the Telemetry menu can be generated via the optional speech output module, Order No. 33001.71, in addition to the transmitter’s audible signals. As standard these telemetry messages are spoken in the German language. The messages are grouped together to form a language pack and stored in the transmitter’s internal memory, but this can be replaced at any time by a language pack in a different language. For more details on this please refer to the section entitled “HIDDEN MODE” starting on page 26.

Importing and exporting model memories

Any model memories can be copied onto a memory card in the transmitter, or copied from the card into the transmitter, so that you can exchange data between identical transmitters, and also back up your data. For more information please see the “Model memories” section starting on page 52.

Note: Some of the special characters used in certain model names cannot be accepted due to speciﬁ c limitations of the FAT or FAT32 ﬁ le system used by memory cards. During the copy process they are replaced by a tilde (~) character.

Using the transmitter for the ﬁ rst time

Preliminary notes regarding the mx-12 HoTT transmitter

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

Preliminary notes

In theory the Graupner HoTT system permits the simultaneous operation of more than 200 models.

However, in practice the mixed operation of different technical systems in the 2.4 GHz ISM 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 page 14. 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.

Switching the transmitter on

When you switch the transmitter on, the following display appears in the centre of the transmitter screen for about two seconds:

RF ON/OFF?

Using the transmitter for the ﬁ rst time

battery needs charging

Within this period you can switch off the RF signal if required by moving the black ﬁ eld to the right using the c or f arrows of the right-hand four-way button; when you do this, ON should appear normal, and OFF in inverse

orm (black background).

You can now switch the RF module off by pressing the

al SET button of the right-hand four-way button.

changes to red, and at the same time the screen switches to the transmitter’s base display:

The symbol combination means that the currently active model memory is already “bound” to a Graupner HoTT receiver, but there is currently no connection with this receiver. (In our example we - of course - switched off the RF signal!)

In contrast, if you switch the transmitter on without switching off the RF signal, the central LED glows an intense blue, and the symbolic transmitter mast ﬂ ashes. At the same time the transmitter emits an audible warning until a connection is made with the corresponding receiver. Once this connection exists, a ﬁ eld strength indicator appears instead of the “x” at the base of the symbolic aerial, for example audible warnings cease.

Low-voltage warning

If the transmitter voltage falls below a particular value, a visual and audible low-voltage warning is generated. The default value is 4.7 V, but this can be varied in the “Basic Settings” menu (page 114).

Firmware update

Firmware updates for the transmitter are carried out at the owner’s discretion using the three-pin PC interface on the back of the transmitter, in conjunction with a PC running Windows XP, Vista or 7. It is essential to check

the state of charge of the transmitter battery before any update; recharge it to be on the safe side, and be sure to back up all stored model memories before carrying out the update, so that you can restore the data if necessary.

To connect the transmitter to a PC you also require the optional USB adapter, Order No. 7168.6 and the connecting lead, Order No. 6466.S.

The latest software and information can be found in the Download section for the corresponding product at www. graupner.de.
