Before use
Thank you very much for purchasing the Graupner
mz-24 HoTT Pro transmitter.
The manual of this transmitter is made of two parts:
The one named Part 1 quick guide is included in the
package of the transmitter and this Part 2 in form of
programming manual is always updated and is available as download in the web page of the related item
on www.graupner.de.
Read both manuals carefully to use the transmitter
optimally und first of all to safely control your models.
If you experience any trouble during operation, take
the instructions to help or ask your dealer or Graupner
Service Centre.
To make the research of important information easier, the single paragraphs in this manual are marked
with model type symbols. They are the same as the
ones used in the transmitter and they show you which
paragraph is related to your model type.
Furthermore you can find in many places in the manual numbers (page number) or strings in blue characters, for example www.graupner.de. Clicking or tap-
ping on brings you directly to the related target.

Before use
Starting up the transmitter
Preliminary remarks
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 significantly less in practice since permits are required for
combined remote operation within the 2.4 GHz ISM
band. The ultimate limiting factor should be overall the
dimension of the available field.
Battery charged?
Since the transmitter is delivered with a partially
charged battery, you will need to charge it observing
the charge instructions included in the Part 1 of the
manual. Otherwise, a warning signal will sound after a short time, and a related message will appear
in the basic display after the voltage drops below a
certain threshold which can be changed in the line
"Batt warning" in the sub-menu "ETC. SET", within
the system menu.
Transmitter startup
After the transmitter is switched on by a motor powered fixed wing model the actual control impulse of
the output 1 or by helicopter model the throttle servo or rpm controller connected to the output 6 are
checked. If this impulse is outside a specifically selected band width for idle and then there is the danger
that the motor can start, the RF module remains off for
safety reasons.
In all other cases by switching on the transmitter the
RF module will be switched on too and in the center
of the display it will appear the message:
At the same time, audible warning signals sound for
a few seconds.
You now have the option of waiting a few seconds
until the display disappears automatically or maintaining the HF transmissions by manually tapping the ON
button, or switching them off by tapping the OFF
button.
You can turn off a receiver that is on and then first
touch ON for demonstration purposes. You are then in
the basic display of the mz-24 HoTT Pro transmitter:
The blue switch symbol at the top left between the
green "TX" and the white "RX" means that the RF
transmission of the transmitter is on. (Otherwise the
symbol would be gray.)
The green "TX" and white "RX" on the left and right
of this switch symbol mean that the currently active
model memory has once been linked to a Graupner-
HoTT receiver but is presently not linked.
Once this link exists, the field strength display appears to the left of the green "TX" and to the right of
the white "RX", and the numeric display underneath
shows the current voltage of the receiver power supply, for example:
If the transmitter is turned on while the RF transmission is off, all of this information is not displayed, and
the RF switch symbol is gray.
If the following warning appears in the display after
the transmitter is turned on, ...
4 Starting up the transmitter
... the currently active model memory is not linked to
any receiver. Tapping on the SET button you accede
immediately the under-menu »Transmitter setting«,
…
... where you can bind your receiver or, tapping on the
BACK button at the top left of the display to terminate
the procedure.
Tip
The basic procedure for initially programming a new
model memory starts on page 42.
Notices
• With this mz-24 HoTT Pro transmitter it is
possible to control up to 12 functions. Any
servos which are connected to connections
13 and higher remain in their middle position
by default and cannot be actuated by the
transmitter as standard.
• For the sake of maximum flexibility and to prevent unintentional misuse, control channels
5-12 are initially not assigned to any control elements, and the servos linked to these channels first remain in their middle position until
an operating element has been assigned. For
the same reason, nearly all mixers are inactive.
Similarly you will find at the begin of the paragraph's description "CTL Set".
• When training, linking or adjusting the remote
control, make sure that the transmitter antenna is always far enough from the receiver antennas. If the transmitter antenna is too close
to the receiver antennas, the receiver will
overdrive, and the red LED on the receiver will
shine to indicate that no signal is received. At
the same time, the feedback channel will stop
working, the field strength bar in the transmitter display will disappear, and the current receiver battery voltage will be displayed as 0.0
V. In this moment the transmitter is in the so
called Fail safe mode. That is, due to the loss
of reception, the servos remain in the last correctly received positions or after a short time
in the preset Fail-Safe positions, until a new
valid signal is received. In this case, move the
two antennas away until the displays return to
normal.
CAUTION
Never turn off the transmitter while operating the model! If this nonetheless acci-
dentally 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, turn
the transmitter on again. Otherwise, the transmitter may freeze directly after being turned on, and
you will be unable to control the model any more.
The transmitter may only be turned on again after
it has been turned off and the described procedure
has been correctly repeated.
5
Starting up the transmitter
The display is basically operated by touching the desired field with a finger or the provided stylus:
By touching the model memory field labeled "M 1" in
the above display with a finger or the provided stylus,
the "Model memory" selection menu opens.
In this sub-menu, you have the possibility for example
to change the model memory by touching the desired
model memory and then the SEL button.
Just as described on page , touch NEWto start programming a Programming a new model , or touch
the field MODEL NAME 1 at the upper edge of the
display to switch to the "Model name" entry menu,
or touch BACK at the top left to return to the previous menu item. In contrast, touch the button SW
[Change page] (generally using the rotation method)
which is also available in several menus to go to the
next page. In the above display of the model memory,
this would be to the display of model memories 07 …
12, etc.
Operating the display
Touching one of the three gear icons identified with
"B", "F", and "S", special selection menus open on
the bottom right from which you can switch to other
sub-menus. Starting with the green BASE menu, the
selection displaysappear as follows, ...
... it should be noted that the blue function menu described from page 120, Function menu contains
model-type-specific sub-menus and for this reason in
divided into a total of three paragraphs.
In the first paragraph starting on page 120 only the
sub-menus for "Vehicles", "Copters" and "Boats"
model types will be described. Because the same
sub-menus are also included in the "blue" menus of
the model type "Helicopter" and "Fixed-wing" models, their description is valid for all the model types
and for space reasons they will not be repeated in
both other paragraphs:
In the second paragraph, beginning on page 154,
exclusively the sub-menus related to the model type
"Helicopter" will be described excluding the above
mentioned "general menus":
And in the third paragraph, beginning on page 182
also excluding the previously described "general
menus", exclusively the sub-menus related to the
"fixed-wing" model type, in which the menus of a
"motor powered model" …
... distinguishes from the menus of a "Glider" model:
The purple System menu which can be accessed
tapping on "S" and whose description begins on page
220, is displayed as follows …
6 Operating the displays
... and the display which can be accessed by tapping on "T" and detailed described from page 225 is
displayed for graphic representation of the telemetry
data e.g. so:

Operating the displays
Warnings
In the display of the mz-24 HoTT Pro transmitter appear different warning windows. These can be divided
into two groups:
"Warning" display
These warning windows primarily appear after the
transmitter is turned on and indicate certain operating
states. In the following illustration, for instance, the
red dot after "CH1-POS" indicates that the throttle
servo connected to the output 1 in fixed-wing models,
or the throttle servo and to output 6 on an helicopter
model, is not in the idle position and there is the risk
of a runaway engine. Until this state persists, the content of the underneath field are obscured for safety
reasons ...
... until the Throttle/Pitch control stick is not in the idle
area:
Basically the it is the same for the warning option "Thr.
HOLD", with the difference that the sub-men "WARN-
ING" of the system menu it can be selected, depend-
ing on the model, if the motor stop function on/off
must be worn:
Notice
In no case you should use the possibility of the
servo reverse of the channel 6 for helicopters and
channel 1 for other model types to reverse the
direction in which the related control stick works. Because the switch-on warning "CH1-Pos" as the "Thr.
HOLD" function do not follow this kind of reverse control
direction. To reverse the control direction use exclusively
the possibility offered by the "Pitch curve" menu for
helicopters models and "Throttle curve" for all the other model types.
Touch SET with a finger or the provided stylus to go
directly to the »TX ctl« display (Transmitter setting) in
which you can link the receiver to the model memory
as described in the related paragraph ...
Or touch the BACK button at the top left to terminate
the procedure.
If instead by switching the transmitter, there is already
a receiver bound to the model memory and inactive
Thr.POS warning, the transmitter will switch on and
the RF module will also be active. Otherwise in the
middle of the display it will standardly appear the following page and at the same time an acoustic warning will be emitted.
You now have the option of waiting a few seconds
until the display disappears automatically or maintaining the HF transmissions by manually tapping the ON
button, or switching them off by tapping the OFF
button.
In the field between the two green lines, the message
"RC signal" indicates that the transmitter is set to normal remote control. Alternately, messages such as
"TEACH signal" or "PUPIL signal" can appear here.
Another – possible – variant is to display "SET F/S" as
an indication that no fail-safe settings have yet been
made.
Notices
• By default,only the monitoring of the "Warn -
ing" sub-menu is activated in the display of
the sub-menu "Warning"of the system menu.
• By selecting REV in the "Thr.HOLD" line of
the "Warning" sub-menu the transmitter can
remind you to switch this function safely on.
8 Warnings
"Acute warning" display
You can open this display by touching mz in the middle of the transmitter's basic display ...
Touch
... and touch the BACK button at the top left to close
the display.
If acoustic warnings sound and the normal transmitter display is covered by this display, take note of the
message in red. An example would be because the
transmitter's supply voltage has reached the warning
threshold set in the sub-menu "»ETC. SET" of the
SYSTEM menu:
At the same time, the display contrast is reduced to
05 to save power.
This warning can be kept from reappearing by touching the ON button at the top right then deleted by
touching the BACK button at the top left in the display. (In specific cases, stop operating the model as
soon as possible and charge the transmitter).
The red number at the top right of each warning field
shows the number of current warnings; in the above
example, the warning is the fourth one. This count can
be deleted by touching the CLR button at the top left.
All other warnings in this display can be handled in
the same way. However, in the case of a field strength
alarm, you can also suppress other alarms triggered
by the low field strength by touching the ON button
under "STRENGTH ALARM" and switch it to OFF.
CAUTION
A switched OFF "Strength alarm" will not
automatically be set to the "ON" position
when the transmitter will be switched on
the next time.

Warnings
3. In the sub-menu »TX ctl«, depending on the number of channels used for the connected flight simulator or for the Training mode, you can select in
the line "DSC output" one of the following modes:
PPM10, PPM16, PPM18 und PPM24. Default setting: PPM10.
Notice
Given the numerous flight simulators on the market, it is possible that the contacts on the jack
plug or DSC module may have to be adapted by
Graupner Service.
Attention
When your transmitter is directly connected to a
desktop computer or laptop by a connecting ca-
ble (DSC cable) and/or a computer interface is
connected to your simulator, the transmitter may be destroyed byelectrostatic discharge. This type of connection should therefore only be used if you protect yourself
from electrostatic discharge while operating the simulator by wearing a commercially available grounding armband. Graupner therefore strongly recommends only
using wireless simulators.
DSCsocket
The abbreviation "DSC" is from the initial letters of the
original function, "direct servo control". With the HoTT
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-24 HoTT Pro transmitters functions as a TRAINER
or PUPIL socket as well as an interface for flight 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
the description of the "Trainer" menu.
2. Connect the other end of the connecting cable to
the desireddevice while observing the relevant operating instructions.
Tip
Make sure that all the plugs are securely inserted in
the respective sockets, and only use the provided
plug-in connections with a 2-pin jack plug on the
DSC side.
The so-called DATA socket is found under the back
cover of the mz-24 HoTT Pro transmitters:
This is for connecting the optional Smart Box ( order
No. 33700) or alternatively for an external Bluetooth
module (No. S8351).
Further information on the Smart Box and the Bluetooth module can be found in the main Graupner FS
catalogue and on the Internet at www.graupner.de for
the respective product.
Data socket
10 Connection on the back side
The headphone connection is found left of center under the back cover of the mz-24 HoTT Pro transmitter:
The socket is for connecting commercially available
ear buds or headphones with a 3.5 mmstereo jack.
(Not included in the set.)
When headphones are plugged in, the transmitter's
speaker is turned off and the stylized icon of a headphone is depicted in color and not gray in the basic
display.
In addition to acoustic signals from the transmitter,
signals and messages associated with the "Teleme-
try" menu are output via this connection. These messages are in German by default. Further information
can be found under "Announces" in the ""Teleme-
try"" section.
Ear phones port
Card slot
Micro-SD and micro-SDHC
Thecard slot for micro-SD und micro-SDHC memory
cards is found on the right of center under the back
cover of the mz-24 HoTT Pro transmitters:
In addition to the micro-SD memory cards that come
standard with the mz-24 HoTT Pro, all conventional micro-SD memory cards with up to 2 GB and micro-SDHC cards with up to 32 GB memory can be
used. The manufacturer recommends using memory
cards with a maximum of 4 GB since this capacity is
normally sufficient.
The memory card that is provided for the transmitter is inserted into the slot behind the cover with the
contacts facing up and then locked in place. After the
memory card is inserted, the transmitter cover can be
closed.
After the provided memory card included in the mz-
24 HoTT Pro set or another memory card has been
inserted in the transmitter at least once, the card is
ready for use directly after the transmitter is turned on.
If the transmitter is turned on after the memory card
is inserted, the stylized memory card icon is displayed
in color and not gray in the basic display. Otherwise, a
few folders are first created on the memory card.
Removing the memory card
Open the cover on the back. Press the SD card slightly toward the card slot to unlock it and then remove it.
Capturing / saving data
The data memory on the SD card is linked to timer
1: Once this starts, data storage also starts assuming that an appropriate memory card is in the card
slot and there is a telemetry link with the receiver. Data
storage stops when the timer 1 is stopped. Timer 1
starts and stops as described in the section "Timer".
The data writing on the memory card is remarked by
an animation of the memory card symbol.
After data storage is finished, an (empty) "Models"
folder and "LogData" folder appear on the memory card. Finally, the log files are saved in subfolders
called "Modelname" named according to the structure
0001_year-month-day.bin, 0002_year-month-day.bin.
If in contrast a model memory is still nameless, the
corresponding log files are saved in a subfolder entitled "NoName" after the memory card is removed
from the transmitter and inserted in the card slot of
a desktop or laptop computer. The data can be evaluated on a compatible computer using the programs
found on the downloads page for the transmitter under www.graupner. de.
Notice
Please note that for technical reasons NO data
representation is possible during the reproduction of MP3 data.
11
Connection on the back side
Mini-USB connection
Located under the rear cover of the mz-24 HoTT Pro
transmitter, there isa connection socket for software
updatesas well as the date andtime settingfrom a
desktop or laptop with one of the Windows operating
systems (XP, Vista, 7 ... 10):
The USB cable that comes with the set is plugged into
this socket. The procedure for obtaining software updates through a computer is described in the software
package instructions.
The software that the computer needs as well as the
appropriate USB driver can be found on the download
page at www.graupner.de for the respective product.
After the required driver and software are installed, the
transmitter can be updated as needed using this connection, or the date and time can be set.
Tip
In order to be aware of important software updates, you
should therefore register at https://www.graupner.de/
de/service/produktregistrierung.aspx. This will allow you
to automatically receive updates by e-mail.
Importing and exporting model memories
To exchange data between transmitters of the same
make or to backup data, model memories can be copied to the inserted memory card, or from the memory
card to the transmitter. More information can be found
in the section "Import from SD card" or "Export to SD
card"..
Notices
• Some of the special characters used in model names cannot be transferred to FAT and
FAT32file systemsdue to the specific restrictions of these file systems used by the memory cardand are therefore replaced by a tilde
(~) during the copying process.
• The model memories of the mz-24 and mz-
24 Pro transmittersare in principle compatible, BUT:
In order to import from an SD card in another
a transmitter type, the desired model memory
must be copied or moved to a corresponding
directory on a desktop or laptop. For example
from \\Models\mz-24 to \\Models\mz-24pro
or vice versa.
More information on "import from SD card"
After importing from an SD card,you always
need to check each and every model function and in particular adapt the control and
switch functionsto the respective transmitter.

Personal notes
Starting up the receiver
Preliminary remarks
Notice
With this mz-24 HoTT Pro transmitter it is possible to control up to 12 functions. Any servos
which are connected to the receiver outputs 13
and higher remain in their middle position by default and
cannot be actuated by the transmitter.
As described in the manual of the related receiver,
after switching it on a LED indicates the missing reception, so long as "its" transmitter is out of range or
switched off or simply the wrong model memory has
been selected in the transmitter. This means that a link
has not (yet) been established with a Graupner-HoTT
transmitter.
To establish a connection with the transmitter, first the
Graupner HoTT receiver must be "bound" to its model
memory in its Graupner HoTT transmitter. This process is known as "Binding". This "binding" is however
required only once for each receiver-model memory
combination or, after changes have been made to one
or more model memories (see page 39), only once
for each transmitter-receiver combination . Therefore
you need to perform a "binding" only after buying a
new transmitter or other receivers or for example if
you have changed model memory (and you can repeat it at any time).
Notice
If the LED of your receiver indicates that it is ready
for use and the receiver does not react to the SET
button and to the control movements, then you
would be better to check the polarity of your receiver
power supply.
On-board voltage display
When a telemetry link exists, the current voltage of
the receiver power supply appears in the transmitter
display in white.
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 the form of a beep that repeats
approximately once per second.
Note the installation instructions for the receiver, receiver antennas and servos on page 16.
Notice
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 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.
If the reset is performed while the transmitter is
switched off or with a not bound receiver, the LED on
the receiver indicates the actual status according to
the description included in the package. If there is no
different description, release the button after about 3
seconds.
If the reset is performed with a not bound receiver, you
can then start a binding process at any time.
If a linked receiver is reset and the associated model
memory is active in the turned-on transmitter, the LED
indicates for about 2-3 seconds, accordingly to the
description included in the package of the receiver, to
indicate that your transmitter/receiver system is ready
to use.
Note
Through a RESET ALL of the settingsin the receiver are brought to the factory settings with the
exception of the HoTT synchronization informa-
tion!
If a reset is performed accidentally, all of these settings
that were made using the "Telemetry" menu in the re-
ceiver should be restored.
Resetting is particularly recommendable when you want
to switch a receiver to a different model. This makes it
easy to keep settings which do not match from being
transferred.
* BEC = Battery Elimination Circuit
14 Starting up the receiver
Channel mapping
The function of each channel is determined by the
transmitter and not the receiver. The channel mapping can be changed directly in the receiver programming the "Telemetry" menu and indirectly through the
menu point "Transmitter output" of the base menu.
Installing the receiver
WhateverGraupner receiver system you use, the
procedure is the same.
For aircraft models, the receiver is installed behind
a strongbulkhead or it is protected against dust and
splash waterincar and ship models. When you install
the receiver, make sure that it is not excessively airtight to prevent it from overheating during operation.
The receiver may not directly touch the fuselage or
chassis since they 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 steel 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.
Note that the cables can shift under the influence of
acceleration during flight. You therefore need to make
sure that the cables cannot move to be directly adjacent to antennas. Moving cables can interfere with
reception.
Installing the receiver
Installing the receiver antennas
In case of single antenna, the orientation is not crucial.
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.
If the fuselages 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 for HoTT receivers with
the 300 mm or 450 mm long antennas No. 33500.2
or 33500.3.
Servo connections and polarity
The servo connections of the Graupner-HoTT receiver are numbered. The supply voltage runs through all
the numbered connections. The polarity of the plug-in
system cannot be reversed. When inserting the plug,
note the small bevels on the side. Do not apply force.
Attention
Do not reverse the polarity of these connections!
This can destroy the receiver and connected devices.
Notice
In compact receivers like the GR-12L HoTT the
outputs 1 … 6 are reverse of 180° if compared to
bigger receivers, for this reason we recommend
to pay a very lot of attention while you connect any plug
to the receiver. If applicable, use a V or Y cable (No.
3936.11).

Components and accessories
Attention
As the manufacturer, Graupner|SJ GmbH recommends only using components and accesso-
ries that have been tested and accepted by
Graupner|SJ GmbH for suitability, functioning and safety. If this is done, Graupner|SJ GmbH will assume responsibility for the product.
However, Graupner|SJ GmbH assumes no liability for
products or accessories by other manufacturers that
have not been approved, and is incapable of evaluating
every single third-party product to determine if it can be
used safely.
Installing the switch
All of the switches must be installed so that they are
not influenced by exhaust or vibration. The switch
knob must be freely accessible over its entire operating range.
Installing the servos
Always install the servos with the provided rubber vibration damper, see the following installing notices.
This is the only way to protect them somewhat from
excessive vibration.
• Install the servos on rubber grommets with tubular
brass spacers to protect them from vibration. Do
not overtighten the fixing screws; this could counteract the vibration protection provided by the rubber grommets. The system offers both safety and
vibration protection for your servos when the servo
fixing screws are properly tightened. The following figure shows how to correctly mount a servo.
The brass spacers are inserted from below into the
rubber grommets:
... they should never be connected as follows:
• In contrast, the sequence for connecting the servosdepends on the model type. Refer to the connection assignments for Helicopter models and
Fixed-wing models.
WARNINGS
• Technical defects of an electrical or
mechanical naturemay cause motors
to start without warning,or may generate flying partswhich can cause significant injuryto you and others!
• Avoid every kind of short-circuit!
Short-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.
• The servo arms must be freely movable throughout
their operating range. Make sure that no linkage
parts block the free movement of the servo.
• Connect the receiver's power supply cable(s) or
the servo connecting cable to the receiver as follows ...
16 Installation instructions
• Once the battery is connected or the
motor is running, always maintain a
safe distance from the hazard area
posed by the propulsion system!
• During the programming process,
make sure that a connected gas engine or electric motor cannot accidentally start. Disconnect the fuel supply
or drive battery beforehand.
Notices
• 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 shock and pressure. 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 spare parts
that we recommend. Always use matching,
original Graupner plug-in connections of the
same design and material.
• When running the cables, make sure that they
are not excessively tight, kinked, or severed. A
sharp edge can also damage insulation.
• Make sure that all of the plug-in connections
are tight. When disconnecting the plug-in
connections, 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
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 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. Always follow the
instructions under Range test.
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 canresult in major
property damage and/or personal injury.

Installation instructions
Servo noise filters for extension cables
No. 1040
The servo noise filter is required when using lon-
ger-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.
Electrical ignitions
Ignition systems of gas engines also generate interference that can impair the functioning of remote controls.
The power 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.
Model function
WARNING
• Neverfly the model over observersor
other pilots. Never endanger people
or animals. Never fly 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 turn 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 three seconds. After this time, turn the transmitter on
again.
• Otherwise, the transmitter may freeze
directly after being turned on, and you
will be unable to control the model.
The transmitter may only be turned
on again after it has been turned off
and the described procedure has been
correctly repeated.
• When operating towed models, maintain a minimum distance of approximately 50 cm between the participating receivers or their antennas. Using
the satellite receiver is an option. Otherwise, malfunctions from the feedback channel are possible.
Checking the transmitter and receiver batteries
Stop operation and recharge the transmitter battery at
the latest when the transmitterbattery is running low,
the message "Charge the battery!" appears in the
display, andan acoustic warning sounds.
Regularly check the battery charge, especially of the
receiver battery. Do not wait until the movements of
the rudder are noticeably slower. Replace dead batteries in a timely manner.
Always follow the manufacturer's charging instructions, and charge the battery for the indicated time.
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. Combinations of old and new cells or
cells from different manufacturers.
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 6 months, and replace them if their performance
is significantly low.
Only use original Graupner rechargeable batteries!

Personal notes
To safely operate the model, a reliable power supply
is required. If the receiver voltage shown on the transmitter display always drops or is generally (too) low
even though the linkage moves freely, the battery is
full, the cross-section of the battery connecting cable
is sufficient, and the transition resistance at the plugin connections is minimal, etc., observe following:
First make sure that the battery remains fully charged
when initially operating the model. Make sure that the
resistance of the contacts and switches is low. Measure the voltage drop over the installed switch cables
under a load since even robust, new switches cause
a voltage drop of up to 0.2 V. This value can be several times higher due to aging and oxidation of the
contacts. In addition, constant vibration and shaking
of the contacts also gradually increase the transition
resistance.
Furthermore, even small servos such as a Graupner/
JR DS-281 draw stall current to 0.75 A when you stop
under a load. Four of these servos in a foam airplane
can hence draw up to 3 A from the on-board power
supply.
Furthermore, servos connected to a 2.4 GHz receiver
receive control pulses more frequently than comparable receivers in the classic frequency range. This affects the power consumption of the receiver system
as well as the characteristic of many modern digital
servos of maintaining the last position specified by
the last control pulse until the next pulse arrives.
You should not only therefore choose a power supply
that does not fail under a permanent high load and
always provides sufficient voltage. To calculate the required battery capacity, add at least 350 mAh for each
analog servo, and at least 500 mAh for each digital
servo.
Using this method, a battery with 1400 mAh represents the absolute minimum for supplying power to
a receiver with four analogue servos. In your calculation, also include the receiver which requires about
70 mA due to its bidirectional function.
Apart from the above considerations, it is generally
recommendable to connect the receiver to the power
supply using two cables. As usual, connect cable "1"
to the "6+B" or "12+B-" output of a GR-16 or GR24 receiver, and cable "2" to the opposite end of the
connector strip labeled "1+B-" or "11+B-" of the receiver. When, for example, using a switch or voltage
regulator with two power supply cables leading to the
receiver. Between the cable and receiver, you can use
a V or Y cable (No. 3936.11, see figure) if one or both
receiver connections also need to be connected to a
servo, speed controller, etc. With the double connection to the switch or voltage controller, you not only
reduce the risk of a cable rupture but also ensure an
even power supply to the connected servos.
If you connect a separate battery to each battery
connection, be sure that each of the batteries have
the same rated voltage and capacity. Never connect
different battery types or batteries with strongly different charges since this can cause an effect similar
to a short circuit. In such cases for safety reasons,
insert voltage stabilizing elements such as the PRX5A receiver power supplies between the batteries and
receiver:
For safety reasons, never used battery boxes or dry
batteries.
The voltage of the on-board power supply is graphically represented, when the model is in use, in the
upper right side of the display so as underneath in
green numerically:
If the voltage falls below the warning threshold (normally 3.8 V) which can be adjusted in the "RX SERVO
TEST" display of the "SETTING & DATA VIEW" of the
"Telemetry" menu, a visual and acoustic low-voltage
warnings are generated.
Attention
Thebattery level should be checked regularly. Do
not wait to charge the battery until the voltage
decreases enough for a warning signal to be
generated.
Tip
A summary of the batteries, chargers and measuring
devicesfor checkingthe power sources can be found
in the main Graupner FS catalogue as well as on the
Internet at www.graupner.de.

Charging the receiver battery
The charging cable (No. 3021) can be connected directly to the receiver battery to charge it. If the battery
in the model is connected by a power supply cable
(No. 3046, 3934, 3934.1 or 3934.3), the battery is
charged via the charging socket integrated in the
switch, or a separate charging connection. The switch
for the power supply cable must be set to "OFF" for

NiMH battery packs with 4 cells
With a traditional 4-cell pack, you can reliably operate
your Graupner HoTT system providing that the above
conditions are observed, and assuming that the packs
have a sufficient capacity and charge.
NiMH battery packs with 5 cells
Battery packs with five cells offer greater leeway in
comparison to 4-cell packs.
You should note, however, that not every servo available on the market can handle the voltage from a
5-cell pack over the long term, especially when the
pack is freshly charged. Some of these servos audibly
"growl" when operated with a 5-pack.
Notice
You should therefore note the specifications for
your servo before you choose to use a 5-cell
pack.
LiFe packs with 2 cells
Given the above considerations, these cells are the
best choice.
LiFe cells are also available in a hard plastic housing
to protect against mechanical damage. Like lithium
polymer cells, LiFe cells can be charged quickly with
suitable chargers and are comparably robust.
In addition, this type of cell can undergo significantly
more charging/discharging cycles than conventional
LiPo batteries. The comparatively high rated voltage
of 6.6 V of two cell LiFe battery packs does not pose
any problems to Graupner HoTT receivers or the servos, speed controllers, gyros, etc. which are approved
for operation with this higher voltage.
Attention
However, practically all of the previously marketed servos, speed controllers, gyros, etc. as well
as many which are offered today have a permissible operating voltage range of 4.8 to 6 V. Stabilized
voltage control such as the PRX (No. 4136) is therefore
needed to connect them to the receiver. Otherwise, the
connected devices may quickly become damaged.
LiPo packs with 2 cells
LiPo batteries are lighter yet they offer the same capacity of NiMH batteries. LiPo batteries also come in
a hard plastic housing to protect against mechanical
damage.
The comparatively high rated voltage of 7.4 V of two
cell LiPo battery packs does not pose any problems
to Graupner HoTT receivers or the servos, speed controllers, gyros, etc. which are approved for operation
with this higher voltage.
Attention
However, practically all of the previously market-
ed servos, speed controllers, gyros, etc. as well
as many which are offered today have a permissible operating voltage range of 4.8 to 6 V. Stabilized
voltage control such as the PRX (No. 4136) is therefore

Installation notice - Receiver system power supply
Lithium-ion (LiIo) and lithium polymer (LiPo) batteries
require special treatment. This is true when charging,
discharging, storing and all other types of handling.
Observe the following specifications:
Charging Graupner LiPo/LiIo batteries
• Since Graupner|SJ GmbH is unable to monitor
whether the batteries are correctly charged and
discharged, all warranties are voided upon incorrect charging or discharging.
• Only use the approved chargers with the associated charging cables to charge lithium ion/lithium
polymer batteries. Any alterations to the charger
and/or charging cables can cause serious damage.
• The maximum charging capacity must be limited
to a factor of 1.05 of the battery capacity.
Example: 700 mAh battery = 735 mAh max.
charging capacity
• To charge and discharge lithium-ion/lithium polymer batteries, only use the plug-in charger in the
set, or the specially designed charger/dischargers
by Graupner, see under www.graupner.de.
• Make sure that the number of cells, charging cutoff and discharging cutoff voltage are set correctly.
Refer to the operating instructions of your charger/
discharger.
• Under these prerequisites, Graupner lithium-ion/
lithium polymer batteries can be charged with a
maximum 2 C (1 C corresponds to the cell capacity) charging current. Starting at a maximum 4.2 V
per cell, continue charging at a constant 4.2 V per
cell until the charging current falls below 0.1... 0.2
A.
• Do not charge with more than 4.20 V per cell.
This would permanently damage the cell and may
cause a fire.
To keep from overcharging individual cells within
the pack, set the cutoff voltage to 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 not 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 can result in the release
of gas, fire and explosion, or other problems.
• The electrolyte and electrolyte vapors 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.
Safety and handling instructions
for lithium-ion (LiIo) and lithium polymer (LiPo) rechargeable batteries
• 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 non-flam-
mable surface (such as concrete) until it cools
down. Never hold the battery in your hand due to
the risk of explosion.
• Batteries from parallel-connected cells, and 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 turn devices off 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 non-flammable, heat-resistant and
non-conductive 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 connection using a balancer or equalizer during
charging.
22 Safety and handling instructions for lithium-ion/lithium polymer batteries
The 1s 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 connection.
• 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
LiIo/LiPo cells should be stocked with about 50% of
their nominal capacity. If the cell voltage falls below 3
V during the stocking, the lithium ion/lithium polymer
cells must be recharged to 50% of the full capacity.
Otherwise, the battery will die during storage and become useless.
Special instructions on discharging Graupner
LiIo/LiPo polymer batteries:
• A continuous current of approximately 1 C does
not pose a problem for Graupner lithium-ion/lithium polymer batteries. If the current is higher, refer
to the instructions in the catalogue. Bear in mind
the maximum load for the plug-in system (see the
maximum discharge current indicated on the battery label).
• Discharging below 2.5 V per cell will damage the
cells and should therefore be avoided at all costs.
• The batteries should never be short-circuited.
Short-circuits generate a very high current which
heats up the cells. This causes a loss of electrolyte, gas formation or even explosions. Graupner
LiIo/LiPo batteries should therefore be kept away
from and not touch conductive surfaces due to the
short-circuit hazard.
• The battery's temperature during discharging
should never exceed +70°C. If this occurs, make
sure that the battery is sufficiently cooled, or reduce the discharge current. The temperature can
be easily checked using the infrared thermometer
(No. 1963). However, the battery may not be discharged using the transmitter's charging socket.
This socket is not designed for this purpose.
Additional instructions on handling
• 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 parallel-connected in exceptions since the cell capacity
and charge can differ. The battery packs that we
supply are therefore preferable.
• The connections of lithium ion/lithium polymer
batteries are not as robust as other batteries. This
holds true particularly for the plus pole connection.
The connections can easily break.
Cells connection
Attention
Direct soldering on the battery cells is impermissible. The heat from direct soldering can damage
battery components such as the separator or
isolator.
Battery connections 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
Attention
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 hous-
ing packaging, deformed cells, the smell of electrolyte
or leaking electrolyte. The battery may not be used in
these cases.
Damaged or useless cells are considered hazardous
waste and must be disposed of properly.
Contact with liquids
Batteries may not be immersed in liquid such astap
water, sea water or beverages. Avoid all contact with
liquids of any kind.

Safety and handling instructions for lithium-ion/lithium polymer batteries
Definition of terms
Control function, control, function input, control channel, mixer, switch, control and logical switch
To make it easier to use the Part 2 of the manual, we
offer a few definitions of terms that appear repeatedly
in the manual.
Control function
A control function is understood as the signal for a
specific control function independent of the signal
within the transmitter. In fixed-wing models set e.g.
the control signals would be throttle, rudder or aileron;
in helicopter models, these would be e.g. pitch, roll
or nick.
The signal of a control function can be transmitted
directly into one control channel or through a mixer
to several control channels. A typical example of the
latter are separate aileron servos, or the use of two roll
or elevation servos in helicopters. The control function
includes the influence of the mechanical control path
on the corresponding servo. This can be spread or
concentrated and modified from linear to highly exponential.
Controls
Controls are the control elements on the transmitter
that are activated directly by the pilot that control the
connected servos, speed controllers, etc. on the receiver. These include:
• The two control sticks for control functions 1 to
4, including the related trims. These four functions
in all the six model types (vehicle, boat, copter,
helicopter, motor airplane and glider) can be exchanged using the mode setting in the software,
such as throttle left or right. Throttle/brake or throttle/pitch left or right. The control stick function for
Throttle/brake flap control for fixed-wing models
or throttle/pitch control in helicopters is frequently
identified as the THR control (channel 1).
• the four proportional dials (DV1 … DV4)
• The two side proportional rotary controls SL1 and
SL2 mounted on the bottom.
• Switches S1 … S8
• the INC/DEC buttons DT1 and DT2
With the type DV and SL proportional controls as well
as the INC/DEC buttons, the servos directly follow the
control position, whereas only a two or three-stage
adjustment is possible with a switch.
The assignment of the controls and switches to the
servos 5 …12 is freely programmable.
Function input
This is an imaginary point in the signal flow and should
not be confused with the control connection on the
printed circuit board. The selected control mode and
the settings "TX OUT SET" line of the ""CTL Set""
sub-menu (transmitter setting) of the base menu influence the sequence beyond the physical connecting
points and this can generate differences between the
number of function inputs and the number of subsequent control channels.
Control channel
From the point at which a signal contains all control
information necessary for a particular servo, whether
directly from the control or indirectly via a mixer, the
term control channel is used.
For example, the "aileron" control function of a fixedwing model for the model type "2AILE" is divided into
control channels for the left and right aileron. Analogously,the "Roll" control function for the helicopter
model "3Sv(2Roll)" governs the controlchannels for
both the left and right roll servo.
This signal is only influenced by the settings made in
the sub-menus "E.P.A" (servo path/servo limit), "REV/
SUB" (servo direction reverse/delay) and "Sub-Trim"
(servo middle and neutral position) to adjust the servo, and possibly the settings in the sub-menu "Out.
Swap" (transmitter output) and is then transmitted by
the transmitter through the RF module. Once it arrives
in the receiver, this signal may be modified by settings
saved in the "Telemetry" menu, after which it controls
the associated servo.
Mixer
The transmitter program contains a variety of mixing
functions. These allow a control function to influence
several control channels and as final result several
servos or even many control functions to influence the
same one servo.
In this context, you can refer to the numerous mixing
functions.
Switch
The series of toggle switches S1 … S8 can also be included in the control programming. The switches are
however generally also intended to switch program
options such as to start and stop the timers, turn mixers on and off, as trainer switches etc. Each of the
switches can be assigned any number of functions.
Related examples are listed in the manual.
Control switch
Since it is occasionally practical to automatically
switch a timer or a function on or off when a control
is in a specific position (a stopwatch turns on/off to
measure engine operating times), the program for the
mz-24 HoTT Pro transmitter also allows you to program control switches.
24 Definition of terms
With these program switches, all you have to do is
specify the switching point along the control path in
the direction of switching. More detailed information
are easily available in the paragraph "Controls and
switches assignment".
Logical switch
Through this option two switches, controls and/or
logical switches or the favorite combination of them,
can be interconnected in an "AND" or "OR" switch. A
total amount of 8 logical switches "L1 … L8" can be
programmed, see description in the "Logical switch"
menu.
25
Definition of terms
Control and switch assignment
Basic procedure
In many places in the program, you can actuate a
control function with a freely selectable control (ST 1
… 4, DV1 … D4, DT1 and DT2, SL1 and SL2), switch
(S1 … 8), or switch between settings with a switch
(S1 … 8), control or logical switch (see below). In both
cases, multiple assignments are always possible. (The
distinction between a control and switch is explained
in the section "Definition of terms").
Notice
It should be noted however that incorrect responses may arise from functional overlaps such
as using the same physical switch as a switch to
switch between Phase switch and as a control for Phase
trimming. Change also your switch assignment.
Since the same method is used to assign the controls,
switches control and logical switches in all relevant
menus, the basic procedure will be explained at this
point which will allow you to focus on the specifics in
the detailed menu descriptions.
Control and switch assignment
In the sub-menu "CTL Set" (control and switch assignment) you can …
… assign transmitter inputs 1 … 12 to operate servos of the mz-24 HoTT Pro transmitter as well as any
control stick (ST1 … ST4) and controls identified as
"DVx", "SLx" or "DTx", or any switch identified as "S1
… S8".
The following window appears in the display after touching the corresponding button, such as
the NONE button to the right of "CH 5" in the second
page of the display of this menu, with a finger or the
provide stylus, and the following window will appear:
Actuate the desired control (control stick 1 … 4, DV1
… DV4, SL1 … SL2, or DT1 … DT2) or switch (S1 …
S8), such as the right proportional rotary control SL1:
Note
The controls are only recognized after a specific
path. Therefore move the control to the left or
right, forward or backward until the assignment
appears on the display. If the length of travel is insufficient, move the control in the opposite direction.
Deleting controls or switches
After the switching or control assignment has been
activated as described, touch the CLR button.
touch
Control or switch assignment interruption
After the switching or control assignment has been
activated as described, touch the N button.
Notice
In few menu positions you can assign only physical controls or switches, that is the reason why in
the pop-up windows that appear in those posi-
tions the LOGIC button is not available, for example:
This is not an error.
26 Control and switch assignment
Assigning logical switch or control
• Switch assignment
The places in the program where a switch, a logical
control or switch can be assigned are marked with
"CTL". So as for example as marked with a red circle in the penultimate line of the following picture
of the Dual Rate / Expo displays:
As soon as you tap on NONE , on the right near
CTL …
touch
... the window in the display will ...
... appear. Actuate the desired switch, for example
the front left 3-way switch S5:
Thus completes the assignation of the switch for
this menu.
• Switch setup
In other menus, in which the switches can be assigned, for example the "PHASE" menu, …
... an accessory display will appear immediately after the switch assignation.
Completely independently from the yellow arrow,
which only indicates the actual position, you can
confirm in this display by touching the related button, in which position di selected phase should be
"ON", for example:
It has to be logically matched with the other switch
positions.
Notice
The phase 1, the "normal phase", is then always active when none of the assigned phase
switch is on the "ON" position.
If you choose the 2-stage switch SW 6 instead of
the 3-stage switch SW 1, the display appears as
follows:
Select the desired switching direction as above.

• Control switch assignment
Move the control that you want to use to activate
the switching function, for example the control
function 3, indicated with "SL2":
The yellow arrow to the right of the bar diagram
illustrates the current control position which can
be accepted by touching the ENT button as the
switching point in the value field to the right of
"POS". Reverse the switching direction by touching REV in the line "DIR(ection)".
In the "MODE" line, the switching function of the
control switch can be changed from on/off like
a 2-stage switch to the switching behavior of a
3-stage switch.
Notice
In this case, be sure to specify a switching position that is not "000". Otherwise, you risk
switching continuously back-and-forth between the two switching states while the relevant
control is in the middle control position.
• Assigning logical switch
After the switching or control assignment has been
activated as described at the beginning of this section, touch the LOGIC button:
touch
In the new window appears a list with the eight
logical switches "L1 ... L8" so as 8 inverted logical switches.
As soon as you tap on the desired switch, it will be
assumed in the output menu, for example:
Notice
Therefore do not forget to program the related
selected logical switch in the "Logical sw"
sub-menu!
Tips
Through the logical switches, see sub-menu "Logi-
cal sw", you can logically interconnect two switch-
es and/or also control switch in a "AND" or "OR"
switch.. A total amount of 8 logical switches "L1 ...
L8" (so as 8 accessory logical switches with reversed
switch direction) are available.
The result of one of these logical switch functions
can also be used as switch function in another logical switch. For more specific details, see the related
menu.
• All of these switches can be given multiple assignments. Make sure that you do not accidentally assign competing functions to a switch. It is recommendable to write down the switching functions.
Practical examples:
• Turning an on-board glow plug heater on and
offwhen a idling switching pointfor the THR control stick is exceeded or undershot. The switch for
the glow plug heater is controlled at the transmitter
by a mixer.
• Automatically turning the stopwatch on and off to
measure the actual flight time of a helicopter by
means of a control switch on the throttle limiter.
• Automatically turning off the mixer "AILE RUDD"
when the brake flap extends to adapt the landing
position of the model to the ground contour when
landing on a slope without affecting the direction
of flight by rudders which are otherwise involved.
28 Control and switch assignment
• Extend the landing flaps and retrim the elevator
while approaching a landing once the throttle control stick is moved beyond the switching point.
• Turn the stop watch on and off to measure the operating time of electric motors.

All of the relevant menus for the previously mentioned
model types are identified in the next section with at
least one of these three model characterizing "colored" symbols, ...
So that when you are programming you will only have
to concern yourself with the related menus.
Connection notices
For vehicle and boat models there are basically four
different ways of assigning the control functions forward/backward and left/right of both control sticks.
The options that are chosen depend on the individual preferences of the model pilot. The compatibility
with the Control modes 1 … 4 ways is however recommended, connect the control function 1 with the
forward/backward function and the control function 4
with the direction function:
Also for copters there are basically four different ways
of assigning the four control functions of roll, nick,
yaw and throttle/pitch of both sticks. The options that
are chosen depend on the individual preferences of
the model pilot. The compatibility with the Control
modes 1 … 4 ways is however recommended to take
the following occupation as example:
