Before use
We are glad that you have chosen a Graupner mz-18
HoTT or mz-24 HoTT 2.4 GHz remote control system.
This system is extremely versatile and can be used by
both beginners and experts.
Please carefully review this manual to achieve the best
results with your remote control, and especially for safe
flying. If any difficulties arise during use, consult the
manual, contact your dealer, or contact the Graupner
Service Center.
Due to technical changes, the information within this
manual may be changed without prior notification.
Introduction
The Graupner remote-control system can be used to
control airplanes, gliders and helicopter models, and
is the perfect choice for anyone looking for a superior
remote-control system. The HoTT system transmits
a range of real-time data such as the motor speed,
voltage, temperature, warnings programmed by the
user, etc. Such data are for example transmitted directly
from a HoTT-compatible governor without requiring
additional sensors. Of course, these data can also be
transmitted from separately-connectable sensors that
are compatible with the HoTT system.
WARNING:
Read all of the instructions so that you
become familiar with how to operate the
system before you start using it. Misuse can
damage the system, cause property damage and/or
serious injury.

Safety instructions
Additional instructions and warnings
Technical defects of electrical or mechanical
nature may cause motors to start without
warning, or may generate flying parts which
can cause significant injury to both you and others.
Avoid short-circuits in any circumstance. Shor t-circuits
can destroy parts of the remote control system and
cause serious burns or explosions depending on the
circumstances and the battery charge.
All parts driven by the motor such as air and water
propellers as well as helicopter rotors, exposed gears,
etc. always pose an injury hazard. Never touch these
parts! A fast-rotating propeller can cut off a finger! Make
sure that no other objects come into contact with driven
parts.
Once the battery is connected or the motor is running,
always maintain a safe distance from the hazard area
posed by the propulsion system.
While programming, make sure that a connected
gas motor or electric motor cannot start accidentally.
Disconnect the fuel supply or drive battery beforehand.
Protect all equipment from dust, dirt, moisture and other
foreign parts. All equipment must be protected from
vibration as well as excessive heat or cold. The models
may only be operated remotely in normal outside
temperatures such as from -10°C to +55°C.
Avoid impacts and crushing. Check for damage to
the housing and cables. Devices that become wet or
damaged may not be used anymore even if they dry out.
Only use the components and recommended spare
parts. Always use matching, original Graupner plug-in
connectors of the same design and material.
When running the cables, make sure that they are not
excessively tight, kinked, or severed. A sharp edge may
damage insulation.
Make sure that all of the plug-in connectors are tight.
When disconnecting the plug-in connectors, do not pull
the cables.
No changes may be made to the devices. This will void
permission to use the device along with the warranty. If
appropriate, send the relevant device to the responsible
Graupner service center; see page 227.
Installing the receiver
For flying models, the receiver is installed
behind a strong rib and is protected against
dust and splash water in car and ship models.
When you install your receiver, make sure that it is not
excessively airtight to prevent it from overheating during
operation.
The receiver may not not directly touch the fuselage
or chassis since this may can directly transmit motor
vibration or impact from landing. When installing the
receiver in a model with a gas motor, all of the parts
must be protected to prevent exhaust or oil from
penetrating. This holds true in particular for the ON/OFF
switch that is installed in the shell of the model in most
cases.
Install the receiver so that the connecting cables for
the servos and power supply remain loose, and so that
the receiving antennas are at least 5 cm from all large
metal parts or wires that do not directly originate from
the receiver. This includes carbon fiber parts, servos,
electric motors, fuel pumps, all types of cables, etc. in
addition to metal parts.
It is preferable to install the receiver away from all
other installed parts at an easily accessible location
in the model. Servo cables may not be wound around
antennas or run next to them.
Make sure that the cables cannot shift to lie directly
adjacent to antennas during flight.
Installing the receiver antennas
The receiver and antennas should be as far away as
possible from drives of all kinds. If the tails are made of
carbon fiber, the ends of the antennas should extend
from the fuselage by at least 35 mm. If necessary,
exchange the approx. 145 mm standard antennas of
HoTT receivers with longer antennas.
It does not matter how the antennas are aligned.
However, a vertical installation of a single receiver
antenna in the model is advantageous. In the case of
diversity antennas (two antennas), the active end of the
second antenna should be at a 90° angle from the end
of the first antenna, and the distance between the active
ends should ideally be more than 125 mm.
Installing the servos
Always install the servos with the provided rubber
vibration damper as shown in the "Installation
instructions" on page 34. This is the only way to
protect them somewhat from excessive vibration.
Installing the linkages
The linkage must be installed so that it is unhindered
and can move easily. It is particularly important for all a
rudder levers to execute their entire range of movement
without any mechanical restrictions.
To make it possible for running motors to be stopped
at any time, the linkage must be adjusted so that the
carburettor is completely closed when the throttle
control stick and trim are moved into idling end position.
Make sure that no metal parts rub against each other
when moving the rudder, vibrations, rotating parts, etc.
This may produce glitches and malfunction of receiver.
Aligning the transmitter antenna
The field strength emitted from the transmitter antenna
when it is pointing in a straight line is weak. It is therefore incorrect to point the transmitter antenna directly to
the model in the belief that this will increase reception.
When a number of remote control systems are being
used at the same time, the pilots should stand next to
each other in a loose group. Pilots standing away from
the group pose a danger both to their own model and
those of others.
If two or more pilots are using a 2.4 GHz remote control
system and are closer than 5 m from each other, it can
cause interference with the feedback channel, and a
range warning may be generated too early. The pilots
should move away from each other until the range
warning stops.
Checklist before starting
Before turning on the receiver, make sure that the
throttle control stick is at stop/idle.
Always switch on the transmitter before the receiver.
Always switch off the receiver before
switching off the transmitter.
WARNING:
If this sequence is not observed and the
receiver is switched on while the associa-
ted transmitter is "OFF", the receiver can
respond to other transmitters, interference, etc. This
can cause the model to move in an uncontrolled
manner and cause property damage or personal
injury.
When models have a mechanical gyro, the following
holds true:
Before turning on your receiver, make sure that the
motor cannot start unintentionally by disconnecting the
power supply.
When the gyro is running down, it frequently
generates so much voltage that the receiver thinks
that the throttle signals are okay. This can cause the
motor to start unintentionally.
Range and function test
Before every use, check the range and
functioning. Firmly secure the model, and
make sure that no one is nearby.
Perform at least one complete range and function
test on the ground, and run through an entire flight
simulation to determine if there are any problems with
the system or the programming of the model. Follow the
instructions on page 77.
WARNING:
If the range and function test as well as the
flight simulation are not performed
completely and conscientiously,
malfunctions may go unrecognized and
reception may be lost which could cause a loss of
control or even cause the model to crash. This
can result in major property damage and/or
personal injury.
Operating models: Airplane, helicopter, ship and
automobile
WARNING:
•
close to power lines. In addition, never operate
your model close to locks and open nautical
traffic. Do not operate your model on open roads,
highways, paths, public walkways, etc.
• Never switch off the transmitter while operating
the model! If this nonetheless accidentally
happens, do not panic, and wait until the
transmitter display goes dark which indicates
that the transmitter is completely off. This will
take at least 3 seconds. After this time, switch on
the transmitter again. Otherwise, the transmitter
may freeze directly after being switched on,
and you will be unable to control the model.
The transmitter may only be switched on again
after it has been switched off and the described
procedure has been correctly repeated.

the rudder are noticeably slower. Replace damaged
batteries in a timely manner.
Always follow the manufacturers charging instructions.
Do not charge the batteries without monitoring them.
Never attempt to charge dry batteries. An acute
explosion hazard exists.
All batteries must be charged before each use. To
prevent short-circuits, first plug the banana plugs of the
charging cable into the charger (make sure the poles
are correct). Then plug in the charging cable plugs into
the sockets of the transmitter and receiver battery.
If you are not going to use your model for a while,
disconnect all power sources.
Never use rechargeable or replaceable batteries with
damaged, defective or different cell types; that is, a
mixture of old and new cells, or cells by a different
manufacturer.
Capacity and operating time
The following applies to all power sources: The capacity
decreases with each charge. At low temperatures,
the internal resistance increases while the capacity
decreases further. As a result, the battery's ability to
discharge and retain power is reduced.
Frequently charging and/or using battery care programs
can also gradually reduce the capacity. Nevertheless,
check the capacity of power sources at least every
six months, and replace them if their performance is
significantly low.
Only use original Graupner rechargeable batteries!
Suppressing interference in electric motors
All conventional electric motors generate
sparks between the collector and
operation of the remote control system depending on
the type of motor.
Interference-suppressed electric motors are therefore
required for the system to work well. Particularly when
the models have an electric drive, the interference
for each motor must be carefully suppressed. Noise
6
brushes which more or less interfere with the
Safety instructions
filters largely suppress such interference and must be
installed.
Follow the related instructions in the motor's operation
and installation instructions.
Additional details on noise filters can be found in the
main Graupner FS catalogue or on the Internet at www.
graupner.de.
Servo noise filters for extension cables
Order No. 1040
The servo noise filter is required when using longer-
than-usual servo cables. The filter is connected directly
to the receiver output. In critical cases, a second filter
can be placed on the servo.
Electronic speed controllers
The performance of the electric motor determines which
electronic speed controller is used.
To keep the speed controller from overloading or
becoming damaged, the current carrying capacity of
the speed controller should be at least 150 % that of the
maximum stall current of the motor.
Exercise caution with tuning motors, because they only
have a few windings and take several times their rated
current in a stall which can destroy the speed controller.
Electrical ignitions
Ignition systems of gas motors also generate interference that may impair the correct function of remote
controls.
The power supply for electrical ignitions should always
be from a separate source.
Only use interference-suppressed spark plugs and
spark plug connectors and shielded ignition cables.
The receiver should be at a sufficient distance from the
ignition system.
Static energy
WARNING:
Magnetic shock waves generated by
lightning can cause remote control
systems to malfunction even if the
lightning is miles away. If a thunderstorm is
approaching, land your model. Static discharge via
the antenna can also be life-threatening.
Note:
• To satisfy the high-frequency transmission
be maintained between the transmitter antenna and
people. Operation at a closer distance is therefore
not recommended.
• Make sure that no other transmitter is closer than
20 cm to prevent electrical malfunctions and impairment of emissions.
• To operate the remote control system, the country setting must be correct for the transmitter. This
is required to satisfy the various national guidelines
(FCC, ETSI, CE, etc.). Follow the respective instructions for the transmitter and receiver.
• Before each flight, perform at least one complete
range and function test, and run through an entire
flight simulation to determine if there are any problems with the system or the programming of the
model. Follow the instructions on page 77.
• Never program the transmitter or receiver while using the model.

• Before each use, make sure that the batteries are in
a satisfactory condition. Defective or damaged cells
or batteries may not be used.
• Cells and batteries may only be used in accordance
with the technical specifications for the specific cell
type.
• Batteries and cells may not be heated, burned,
short-circuited or charged with excessive current
or with reversed polarity.
• Batteries from parallel-connected cells, combinations of old and new cells, cells of different
makes, sizes, capacities, manufacturers, brands
or type may not be used.
• Batteries which have been installed in a device
should always be removed when the device is not
being used. Always switch off devices after you have
finished using them to prevent battery drainage. Be
sure to charge the batteries in a timely manner.
• While they are being charged, the batteries must be
placed on a nonflammable, heat-resistant and nonconductive surface. Combustible or highly flammable
objects are to be kept away from the charging area.
• Batteries must be monitored while they are being
charged. The maximum charging current specified
for the respective cell type may not be exceeded.
• If the battery heats up above 60°C while it is being
charged, stop charging and let the battery cool down
to approximately 30°C.
• Do not charge batteries that have already been
charged, are hot, or have not discharged to the
specified level.
Batteries as well as individual cells are not
toys and must be kept from children. They
must therefore be stored out of the reach
• The batteries may not be modified. Do not directly
solder or weld the cells.
• If handled improperly, there is a danger of fire,
explosion, irritation and burns. To extinguish a fire,
use a fire extinguishing blanket, CO2 extinguisher
or sand.
• Leaked electrolyte is caustic and should not be
touched or come into contact with your eyes. In case
of emergency, rinse with a large quantity of water
and then consult a physician.
• The valve openings for the cells should never be
blocked or sealed, for example with solder. When
soldering, the maximum soldering temperature of
220°C should not exceed 20 seconds.
• To avoid deformation, avoid excessive mechanical
pressure.
• If the batteries overheat, proceed as follows:
Disconnect the battery, and place it on a nonflamm-
able surface (such as cement) until it cools down.
Never hold the battery in your hand due to the risk of
explosion.
• Make sure to observe the charging and discharging
instructions.
General instructions
The battery capacity decreases each time it is
charged and discharged. Storage can also
gradually reduce the battery's capacity.
Storage
Batteries may only be stored completely discharged
in dry rooms with an ambient temperature of +5°C to
+25°C.
NOTE:
The cell voltage should not fall below 1.2 V
when stored for a long time. Before being
stored, the battery may have to be charged.
Equalizing the individual battery cells
• To adjust the cells of a new battery to each other,
charge them normally to the maximum charge. As a
rule of thumb, charge empty batteries for 12 hours
with a current which is 1/10 of the rated capacity
(the "1/10 C" method) The cells will then all have the
same charge. The cell charge should be equalized
about every 10th charge in order to extend the life of
the battery.
• If you are able to discharge individual cells, do this
before each charging. Otherwise, the battery pack
should be discharged to 0.9 V per cell. With the fourpack used in the transmitter, this corresponds for
example to a discharge voltage of 3.6 V.
Charging
While charging, the specified current, charging time and
temperature range should be observed under constant
monitoring. If you do not have a suitable fast charger
that allows the charging current to be precisely adjusted,
charge the battery the usual way using the 1/10 C
method (see the example above).
Given the different charges of the cell, transmitter
batteries should be charged using the 1/10 C
method whenever possible. The charging current
should never exceed the maximum permissible level
indicated in the transmitter instructions.
Fast charging
If your charger has this option, set the delta peak cutoff
voltage to 5 mV per cell. Most chargers are permanently
set to 15 … 20 mV per cell and can therefore be used
for both NiCd batteries as well as NiMH batteries. In
case of doubt, consult the operating instructions or the
dealer to determine whether your device can handle
NiMH batteries. In case of doubt, charge your batteries
with one-half the indicated maximum charging current.
Discharging
All of the batteries that are sold by Graupner and GMRacing can handle a maximum continuous charging
current of 6… 13 C depending on the battery type (refer
to the manufacturer's specifications). The battery life
decreases as the continuous current load increases.

As is the case with all high-quality products, the following safety instructions and handling guidelines must be
observed to ensure long, trouble-free and safe use of
lithium-ion and polymer batteries.
Lithium-ion/lithium polymer batteries require special

within the pack, set the cutoff voltage between 4.10
… 4.15 V per cell in order to extend the battery life.
• The permissible temperature range for charging and
discharging lithium-ion/lithium polymer batteries is
0 … +50 °C.
• Batteries as well as individual cells are no toys and
must be kept from children. They must therefore be
stored out of the reach of children.
• Keep batteries away from infants and small children.
If a battery is swallowed, immediately consult a
physician or go to an emergency room.
• Never place a battery in a microwave or under
pressure. This may cause smoke, fire or an
explosion.
• Do not disassemble lithium-ion/lithium polymer
batteries. Disassembling a battery can cause internal
short-circuits. This same results in the release of gas,
fire and explosion, or other problems.
• The electrolyte and electrolyte vapours within
lithium-ion/lithium polymer batteries are hazardous
to health. Avoid direct contact with electrolytes. If the
electrolyte comes into contact with your skin, eyes or
other body parts, use a large amount of fresh water
for rinsing and then consult a doctor.
• Before each use, make sure that the batteries are in
a satisfactory condition. Defective or damaged cells
or batteries may not be used.
• Cells and batteries may only be used in accordance
with the technical specifications for the specific cell
type.
• Batteries and cells may not be heated, burned,
short-circuited or charged with excessive current
or with reversed polarity.
If handled improperly, there is a danger of fire,
explosion, irritation and burns. To extinguish
a fire, use a fire extinguishing blanket, CO2
extinguisher or sand.
• If the batteries overheat, proceed as follows:
Disconnect the battery, and place it on a
nonflammable surface (such as cement) until it cools
down. Never hold the battery in your hand due to the
risk of explosion.
• Batteries from parallel-connected cells, combinations of old and new cells, cells of different
makes, sizes, capacities, manufacturers, brands
or type may not be used.
• Batteries which have been installed in a device
should always be removed when the device is not
being used. Always switch off devices after you have
finished using them to prevent battery drainage.
Dead lithium-ion/lithium polymer batteries are
considered defective and may not be reused.
• Be sure to charge the batteries in a timely manner.
While they are being charged, the batteries must be
placed on a nonflammable, heat-resistant and nonconductive surface. Combustible or highly flammable
objects are to be kept away from the charging area.
• Batteries must be monitored while they are being
charged. The maximum charging current specified
for the respective cell type may not be exceeded.
• You may only charge a pack of series-connected lithium-ion/lithium polymer batteries all at once as long
as the voltage of the individual cells does not deviate
by more than 0.05 V, or if the differences in voltage
are monitored and equalized by a balancer connector using a balancer or equalizer during charging.
The lithium-ion battery in the set comes with a
special safety shut off. The voltage differences
between individual cells are therefore not balanced
by means of the usual balancer plug-in connector.
• If the battery heats up above 60 °C while it is being
charged, stop charging and let the battery cool down
to approximately 30 °C.
• The batteries may not be modified. Do not directly
solder or weld the cells.
• To avoid deformation, avoid excessive mechanical
pressure.
• Make sure to observe the charging and discharging
instructions.
Storage
Lithium lithium-ion/lithium polymer cells should
be stored charged with 10-20% of their
lithium-ion/lithium polymer cells must be recharged to
10-20% of the full capacity. Otherwise, the battery will
die during storage and become useless.

never exceed +70°C. Otherwise, make sure that the
battery is sufficiently cooled, or reduce the discharge
current. The temperature can be easily checked
using the infrared thermometer (order No. 1963).
However, the battery may not be discharged using
the transmitter's charging socket. This socket is not
designed for this purpose.
The battery capacity decreases each time
it is charged and discharged. Charging
when the temperature is too high or too
low can also gradually reduce the battery's capacity.
After 50 cycles, the battery capacity of models is
only 50-80% of that of a new battery due to the
occasionally high discharge current and induction
current of the motor, even when all charging and
discharging instructions have been followed.
• Batteries may only be series-connected or parallelconnected in exceptions since the cell capacity and
charge can differ. The battery packs that we supply
are therefore preferable.
• The connectors of lithium-ion/lithium polymer
batteries are not as robust as other batteries. This
holds true particularly for the plus connector. The
connectors can easily break.
Cell connector
Direct soldering on the battery cells is not
permitted.
The heat from direct soldering can damage
battery components such as the separator or isolator.
Battery connectors should only be created by spot
welding in the factory. If the cable is missing or severed,
have it repaired professionally by the manufacturer or
dealer.
Replacing individual battery cells
Individually battery cells may only be
exchanged by the manufacturer or dealer and
not by the user.
Do not use damaged cells
Damaged cells may not be used.
Indications of damaged cells include damaged
housing packaging, deformed cells, the smell

General operating instructions
mz-18 and mz-24 HoTT transmitters
Transmitter power supply
The mz-18 HoTT transmitter comes standard with a
rechargeable NiMH battery with 2000 mAh capacity, and
the mz-24 HoTT transmitter comes standard with a
1s2p lithium-ion battery with 4000 mAh capacity (subject
to modifi cation).
The standard battery installed in the

• In a special calibration menu that can be opened by
touching the voltage display in the basic display of
the transmitter using a fi nger or the provided stylus,
the real displayed voltage can be fi ne-tuned (see
"Battery warning" on page 202).
The rechargeable NiMh battery of the mz-18 HoTT
transmitter or the 1s2p lithium-ion battery of the mz-24
HoTT transmitter may be charged as described below
using the charging socket on the rear labelled CHARGE
with the provided plug-in charger:
The charging socket comes standard with a protective
diode that protects against polarity reversal. Original
Graupner automatic chargers recognize the battery
charge. Note the setting instructions of the charger
which is used.
Polarity of the mz charging socket
The charging cables available on the market by other
manufacturers frequently have different polarities. For
this reason, you should only use original Graupner
charging cables with order No. 3022.
Charging the transmitter battery using the plug-in
charger
The charging time with
the plug-in charger
provided in the set may
be up to 15 hours depending on the existing
transmitter battery
charge.
Do not use
plug-in
chargers by other manufacturers or chargers
designed for different battery types. If the output voltage
is too high or the plug polarity is incorrect (see above), it
can cause signifi cant damage. We recommend labelling
the plug-in charger.
Consult the corresponding safety instructions on
pages 4 … 12.
The transmitter must be switched off while
charging. Never switch on the transmitter
when it is connected to the charger. If the
charging is interrupted even for a short time, the
charging voltage can rise enough to immediately
damage the transmitter from overvoltage. You should
therefore make sure that all plug-in connectors are
well-seated.

the charger cable with order No. 3021 is required.
Other chargers as well as details on the listed chargers can be
found in the main Graupner FS catalogue or on the Internet at
www.graupner.de.
First plug the banana plugs of the charging
cable into the charger, and then plug the
other end of the charging cable into
the transmitter charging socket. Never connect the
bare ends of the plugs of a charging cable that is
already connected to the transmitter!
Description of the transmitter - General operating instructions
16
To prevent damage to the transmitter, the charging
current should generally not exceed 1.5 A. Limit the
charge current if necessary.
Removing the transmitter battery
To remove the transmitter battery, fi rst remove the cover
of the battery compartment on the back of the transmitter.
Battery connecting plug
Then disconnect the transmitter battery plug by carefully
pulling the supply cable. Then lift the battery and pull it
gently off of the velcro.
(The display shows the battery for the transmitter
mz-24 HoTT.)
Inserting the transmitter battery
The battery connector is protected by two bevelled
edges from polarity reversal when plugging in. The free
socket of the battery connector faces upward at the
bottom of the battery compartment as can be seen in
the following picture. The plus pole (red cable) is in the
middle, and the minus pole (brown or black cable) is on
the side facing the battery.
Never forcefully insert the plug into the socket on the
transmitter board.
Then place the battery into the compartment, and close
the battery cover.
Battery operating time in the bottom left display
The time (green) is automatically reset to 0:00 once the
transmitter battery voltage is recognizably higher than
the most recent voltage after the transmitter is started,
and the display shows the cumulative operating time of
the transmitter since last charging.

General charging instructions
•
•
transmitter, the transmitter charging current should
generally not exceed 1.5 A. Limit the charge current
if necessary.
If the transmitter battery is charged with more than
1.5 A, it must be charged outside of the transmitter.
Otherwise, the printed circuit board may be damaged
from overloading the printed connectors and/or
overheating the battery.
• Perform a few test charges to make sure that the
automatic cutoff of automatic chargers works. This is
especially true when you want to use an automatic
charger to charge the NiMH battery which comes
standard in the mz-18 HoTT transmitter, or the
lithium battery which comes standard in the mz-24
HoTT transmitter. Monitor the cutoff behaviour if the
charger that you are using has this option.
• Do not discharge the battery or run battery care
programs using the charging socket. The charging
socket is only for charging.
• Always first connect the charging cable to the charger, and then connect it to the receiver or transmitter
battery. This prevents unintentional short-circuiting
with the bare ends of the charging cable plug.
• If the battery becomes hot, check the battery and
exchange it or reduce the charging current.
• Do not charge the batteries without monitoring
them.
• Follow the safety instructions and handling
guidelines starting page 4.
Follow the charging instructions of the
charger manufacturer and battery
manufacturer.
Do not exceed the maximum permissible
charging current of the battery
manufacturer. To prevent damage to the
Adjusting the control sticks
Both the left and right control sticks can optionally be
set from neutralizing to non-neutralizing and vice versa.
The resetting force on the control sticks can be set to
the pilot's preferences. The related adjusting system
is on the back of the transmitter in the battery compartment, under the rubber covers, and under the side
grips attached with double-sided adhesive tape (see the
marks in the following picture). Make the desired adjustment by turning the relevant setscrew using a Phillips
or standard screwdriver. Hold the control stick tight as a
precaution:

To change the standard setting of the left and right
control sticks, turn the screw toward the inside of the
transmitter until the relevant control stick can move
freely from stop to stop, or turn it outward until the
control stick resets itself independently.
Adjusting the length of the control sticks
Both control sticks can be gradually adjusted over
approximately 8 mm to adapt the transmitter control to
the pilot's preferences.
Hold down the bottom half of the knurled grip, and
loosen the screwed connection by turning the top part:
You can now lengthen or shorten the control stick by
screwing it up or down. Then clamp the top and bottom

during fl ight without looking at the display. If you go past
the middle position, a brief pause is inserted.
The current trim values are automatically saved when
the model memory is changed. In addition, the digital
trim functions within a memory in specifi c relation to the
Quick Link (with the exception of the trim of the Throttle/
brake valves or the gas/pitch control stick called control
function "THR" (channel 1)).
When a gas motor is selected in the "Drive type" display,
page 47, the trim of the throttle control stick only functions for wing or helicopter models in the bottom half of
the control stick path, that is, only in the starting range.
The current trim positions are displayed numerically and

system, "direct servo control" using a diagnostic cable is
not possible for technical reasons.
The standard two-pin DSC socket on the back of the
mz-18 HoTT and mz-24 HoTT transmitters functions
as a trainer or pupil socket as well as an interface for
fl ight simulators or other external devices.
To ensure a correct DSC connection, observe the
following:
1. Perform any necessary adaptations in the menu.
To adapt to the transmitter to a trainer system, see
page 107.
2. Connect the other end of the connecting cable to the
desired device while observing the relevant operating
instructions.
Important:
Make sure that all the plugs are
securely inserted in the respective
plug-in connectors with a 2-pin jack plug on the
DSC side.
3. In the "Transmitter control" submenu, page 74,
you can set one of the following modes in the "DSC

Introductory remarks on the mz-18 HoTT and mz-24 HoTT transmitters
Theoretically, the Graupner-HoTT system allows
more than 200 models or remote-control systems to
be operated at the same time. This number will be
signifi cantly less in practice since permits are required
for combined remote operation within the 2.4 GHz ISM
band. Generally however, more models can be operated
at the same time within the 2.4 GHz band than was
previously the case within the conventional 35/40 MHz
frequencies.
Battery charged?
Since the transmitter is delivered with an uncharged battery, you will need to charge it observing the instructions
on page 15. Otherwise, a warning signal will sound
after a short time and a related message will appear
in the basic display after a certain voltage is reached
(normally 4.8 V with the mz-18 HoTT transmitter and
3.6 V with the mz-24 HoTT transmitter) which can be
changed in the line "Bat. warning threshold" in the submenu "Etc.Set" page 202, within the system menu.

new valid signal is received. In this case, move
away until the displays return to normal.
WARNING:
Never switch off the transmitter while
operating the model! If this nonetheless
accidentally happens, do not panic, and
wait until the transmitter display goes dark which
indicates that the transmitter is completely off. This
will take at least four seconds. After this time,
switch on the transmitter again. Otherwise, the
transmitter may freeze directly after being switched

Preliminary remarks
The mz-18 HoTT and mz-24 HoTT remote control sets
each come with a GR-24 bidirectional 2.4 GHz receiver
which can be connected to a maximum of 12 servos, as
well as a bidirectional GR-12L HoTT receiver.
Using connectors 1 … 9, a maximum of 9
servos can be operated with the mz-18 HoTT
transmitter together with the GR-24 HoTT
receiver which comes with the set and is already linked
to the fi rst model memory. Any servos which are
connected to connectors 10 … 12 remain in their middle
position by default and cannot be actuated by the
transmitter.
In contrast, a maximum of 12 servos can be operated
with the mz-24 HoTT transmitter together with the
GR-24 HoTT receiver which comes with the set and is
already linked to the fi rst model memory.
If you have already switched on the GR-24 HoTT receiver that comes with the set and its transmitter is not in
range or is switched off, the red receiver LED will shine
for a few seconds and then start to slowly fl ash. This
means that a link has not (yet) been established with a
Graupner-HoTT transmitter. Once a link is established,
a green LED shines continuously, and the red LED
extinguishes.
To establish a telemetry connection with the transmitter,
fi rst the Graupner HoTT receiver must be "bound" to its
model memory in its Graupner HoTT transmitter. This
procedure is called "binding." This binding only needs
to be performed once for each receiver/model memory
combination (see) and has already been done at the
factory for model memory 1 for the devices provided in
the set. Binding therefore only needs to be performed for
other receivers when the memory is changed (you can
repeat this at any time after changing a transmitter).
NOTE:
An activated receiver that has linked at least
once with "its" transmitter responds to any
incoming control signals from other model
memories of "its" transmitter like a secondary receiver.

Temperature warning
If the receiver temperature falls below a threshold which
can be set in the receiver (-10°C by default) or exceeds
a top warning threshold (+55°C by default) which can
also be set in the receiver, the receiver emits a warning
in form of a beep that repeats approximately once per
second.
Servo connectors and polarity
The Servo connectors of the Graupner-HoTT receiver
are numbered. The polarity of the plug-in system cannot
be reversed. When inserting the plug, note the small
bevels on the side (see the fi gures on the next doublepage). Do not apply force.
The supply voltage runs through all the numbered
connectors.
With the GR-24 receiver, the two outermost vertical
connectors are for the battery. These are identifi ed with
"11+B-" and "12+B-". A corresponding servo along
with the power supply can be connected to the two
connectors using a V or Y cable (order No.: 3936.11).
NOTE:
Do not reverse the polarity of these connectors! This can destroy the receiver and
connected devices (see the next double
page).
The function of each channel is determined by the
transmitter and not the receiver. Depending on the make
and model, throttle servo connection, along with other
connections, can be different. With Graupner|JR and
Graupner remote controls, this connection is at channel
1 for fi xed-wing models, and at channel 6 for helicopters.
Note the installation instructions for the receiver, receiver antennas and servos on page 34.
Final instructions:
•
The signifi cantly higher servo resolution of
the HoTT system leads to a noticeably
more direct response in comparison to the
previous systems. Take time to familiarize yourself
with this more sensitive response!
• If you are using a speed controller with an integrated
BEC* in addition to the receiver battery, the plus
pole (red cable) may have to be removed from the
3-pin plug depending on the speed controller. In this
regard, take note of the related information in the
speed controller instructions.
Use a short screwdriver to
carefully lift the middle tab of
the plug (1), remove the red
1
2
cable (2), and use electrician's
tape to protect against shorts
(3).
Reset
To reset the receiver, hold down the SET button on the
top of the receiver while turning on the power. Hold
down the SET button of the receiver until, after about
3 seconds, the slowly fl ashing red/green LED extinguishes for about 2 seconds.
If the reset procedure is performed while the transmitter
is switched off or the receiver is not linked, the green
and red LEDs fl ash four times over about 3 seconds in
the standard GR-24 receiver that comes with the set,
then both LEDs extinguishes for about 3 seconds, and
then the red LED starts to fl ash. Release the button
once the LEDs extinguishes.
