Safety instructions 7
•The Zwo4 radio ist not licensed for flying
models.
•Only use the radio for controlling
unmanned vehicles and if no living thing
is in danger.
•If you are making adjustments always
place the model so it can’t drive acciden-
tally or damage the servos.
Charge the battery only with the specified
charging currents, use a suited charger
for NiMH batteries designed for model
vehicles. See chapter Quick Start -
Battery Charging
•Check electronic or mechanic connec-
tions in your model regularly.
•Check how your model reacts if there is
bad reception by turning the radio off.
The model should not drive on its own. If
it does anyway it is probably because of
the ESC - please use high quality ESCs
with protective functions.
•Protect the radio from humidity - other-
wise errors may occur.
•Avoid using your radio in extreme
temperatures - it may damage the LCD
display.
•Clean the surface with a soft cloth - do
not use an acrid detergent.
Safety instructions

8 Tips: The Difference to Model Flying
The Zwo4 radio offers maximum compati-
bility and works with all systems based on
standards of Robbe/Futaba und
Graupner/JR. See chapter Multiswitch
Assign names
You can not only assign a name to each
servo channel, you can also give each
control a different name that is shown in the
menus. You can even choose a name sepa-
rately for left and right for each control
because one control often has two functions
e.g. horn and starter.
Trim
The trim - the adjustment of the center posi-
tion for joystick channels - is less often used
for driving model vehicles than for flying.
Therefore with the HS12 the softkeys are
also used to adjust the trim settings, see
[Menu] > [Trim]. Alternatively you can use a
softkey pair or the second level of a joystick.
See chapter Mixer Functions - Quick Trim
Sliders and rotary knobs
You won’t find any on your HS12 because
they can make it difficult to switch between
different models. The second level of
joystick controls is much more practical for
drive sets.
For setting values like the idle speed of a
pump you can use a softkey pair. The set
values stay the same even if you switch to a
different model.
Mixer
Radios for model flying use a variety of
preset mixer functions (not useful for vehi-
cles). The Zwo4 radio offers a universal and
clear concept.
Each control can operate up to three
servo channels - one servo channel can be
controlled by any number of controls.
All necessary settings are available for the
controls so there is no need for a special
mixer menu. See examples in chapter Mixer
Functions
Dual Rate
(Travel adjustments)
If you want the control travel to be switch-
able you can use the level switches. This
way you can make extensive adjustments
because all settings and mixer functions can
be switched. See chapter Mixer Functions -
Dual Rate
The Zwo4 radio is designed for driving
model vehicles and is different than
radio systems you may know for flying.
To make the change easy for you here
are the main differences:
Easy control
The more controls, channels and functions
there are the harder it gets to navigate
through the menus with a rotary knob or mini
joystick. The Servonaut HS12 makes it
easy: Use the softkeys which are labeled in
the display. In addition the four colored
menu buttons above the display are short-
cuts for important functions.
Two levels of functions
All joysticks and softkeys can have two func-
tions, you switch between them with the
level switches above the joysticks (standard
version without 3D sticks).
Multiswitch
Using a multiswitch to have more channels
available is common, mostly to control light
sets or if many servos need to be controlled.
1. Tips: The Difference to Model Flying

Tips: The Difference to Model Flying 9
Mode
(Control assignments)
With the Zwo4 radio you can choose freely
which function is assigned to which control.
For a quick change use the settings under
[Menu] > [Swap control]. It even allows you
to switch the function of a joystick with that
of a softkey pair.
Switches and buttons
They are not upgradeable. Instead the
radio has six universal softkey pairs that
can be labeled in the display. Each pair
relates to one servo channel. Because of
the level switches there are 2 x 6 controls
available. With the control type you can
choose if it acts as a button, momentary
switch, three way switch, a combination or
thanks to a hydraulic simulation as a propor-
tional control.
Fail Safe
With radios for flying each channel can have
a fail safe position which is activated if the
connection between radio and receiver is
bad. This way for example the ESCs stop.
Premise is that the positions are correctly
adjusted - which often is not the case.
Therefore the Zwo4 setup makes it easy for
you and cuts all signals to the ESCs if there
is bad reception. This method is very secure
because it works without further adjust-
ments and with almost all common ESCs.

Quick Start 11
Set up special functions
If you want to set special functions for the
softkeys and channels 5 to 12 you have to
assign the servo channels to the controls.
Example:
Fifth wheel plate lock on channel 5
•Press [Menu] > [Control] and then a key
of the softkey pair you want to use e.g.
upper right.
•Press [Type] and choose the channel
type [Switch - +].
•To assign a channel to a control go to the
second menu page with the blue button
[1v4].
•Press [Change] and choose [x5 Servo] in
the channel menu.
•By pressing [Test] you can switch to the
operating screen to test if the fifth wheel
plate lock works. Press one of the menu
buttons to get back to the control menu.
•Press [OK] a few times to get back to the
operating screen.
•You can adjust the direction of the servo
rotation and the endpoint with [Menu] >
[Servo] > [x5 Servo]. Save a name for the
channel e.g. fifth wheel.
•Press [Menu] > [Control] and then the key
of the softkey pair you want to use to get
to the control menu. Here you can assign
a name separately for the left and right
key e.g. Open and Close.
New Model
Go to the Model menu with
[Menu] > [Model] > [New Model].
Choose the template MC19 or F14
depending on your favorite layout for the
joysticks. See chapter Menu Model -
Channel Assignment
Set a name for your model. If you don’t
choose one the radio shows „Model“ and the
model number instead.
Choose light set (optional)
If you have a standard light set in your
model you can choose a template in the
next step with [Light set]. See chapter Light
Sets for details
With [OK] back to the main menu.
Bind the receiver
Follow the instructions of the receiver
manual and put it in bind mode. Then press
[Receiver] and [Bind] on the radio. The
receiver flashes green. Follow the receiver
manual.
Charging the battery
Your Zwo4 radio has a NiMH battery with 4
cells and 4,8 V. There are two ways to
charge it: a quick charge and a normal
charge.
•Quick charge: Adjust your battery
charger to NiMH and the charging
current to 0,5 or 1A. It takes 2 to 5 hours
to charge. Do not leave the radio unat-
tended.
•Normal charge: We recommend a
charging current of 200 mA for normal
charge. It takes 14 hours. If the radio
stays connected to the charger longer it
is not dangerous.
Caution: You need a special type of
charger.
Choose the language
You can change the menu language from
German to English with [Menu] > [Sender]
> [1v2] > [DEU/ENG].
3. Quick Start: The First Steps

12 Enter Names
If there are many controls and channels you
lose track easily. Therefore with the Zwo4
radio you can name not only the servo chan-
nels but each control individually. Because
one control often has two functions e.g. horn
and starter you can save two names - for left
and right. If you only want one name for both
just save one for [Name left/down].
Tip: Always assign a name, a short
one at least, to make the handling
easier - e.g. S22 for the ESC channel.
You always find the naming option in the
submenus for controls, servo, radio and
model.
Menu Buttons

Press the keys once or repeatedly to insert
numbers or letters. With [OK] you confirm
your input and get back to the menu.
4. Enter Names

Telemetry 13
Your Servonaut Zwo4 receiver measures
the BEC respectively receiver supply
voltage and also the driving battery voltage.
All measured values are transmitted to the
HS12 radio via telemetry.
In the operating screen press the yellow info
button to see the values. Special feature:
The Zwo4 radio shows it for up to four
receivers at the same time - the data for the
active model and also for three models in
stand-by.
For BEC and supply voltage you can set an
alarm value for each model with [Menu] >
[Receiver] > [BEC threshold] and [Bat
threshold].
5. Telemetry Show data, adjust alarms

You can assign two functions to all softkey
pairs and joysticks - switchable with the
level switches. One control element can
have function on level 1 and additional on
level 2a or 2b - not both at the same time.
•Choose the level on which you want to
activate a function with a level switch
(level 1, level 2a or level 2b). If both level
switches are in the center position the
main level (level 1) is active.
Caution: Make sure that not one of
the level switches is in the upper posi-
tion if you want to adjust the main level. See
chapter Menu Control
•If you want to adjust level 2a or level 2b,
move the left (2a) or right (2b) level
switch in the upper position.
•Start the controls menus with [Menu] >
[Controls] and move/press the control
you want to use.
•Before you make adjustments activate
the control with the button [active].
Now you can also adjust the function for
level 2a or 2b. See chapter Menu Control
•If you do not want the control to have a
function on this level deactivate it again
by pressing [active].
14 Level Switches
Typical applications:
•More than 6 special functions: Assign
the most used functions to the softkey
pairs of the main level (level 1) and the
lesser used on level 2a or 2b.
•Excavator with track drive: Assign the
joysticks according to Euronorm on the
main level (level 1). On level 2a or 2b you
can additionally assign one joystick for
steering the track drive. See chapter
Mixer Functions
•Excavator with grab: Assign the
joysticks according to Euronorm on the
main level (level 1). On level 2a or 2b you
can additionally assign one joystick for
steering the grab.
•Dual Rate for switchable servo travel:
If you want the travel of a control switch-
able you can do it with the level switches
and a mixer. First move/press the control
for the first function and adjust it accord-
ingly. Then actuate it again together with
the level switch for the second function.
Or you can use the Control Copy with
[Menu] > [Control Copy]. Choose the
same mixer channels for each variant.
You can adjust them separately.
To make things clearer when using multiple
functions or in particular the 3D-stick, the
active level is shown in the middle of the
display.
For the main level a ´1´is indicated.
For the levels 2a and 2b an ´a´ or a ´b´ is
shown respectively.

ments of these softkeys. If you press
[Emerg. off] all three channels react
according to their channel type. See
chapter Servo - Channel Type
•Two steering servos with different
travel radius: Choose the channel type
[Servo] for both steering servos.
Tip: Assign names to both channels,
e.g. Front and Rear.
Set the right direction of rotation in the
channel menu with [Reverse] for both
servos. Choose the control type [Normal]
for the steering controls. For 1. assign-
ment choose the channel for front
steering, for 2. assignment the channel
for rear steering. Adjust [Rate right] and
[Rate left] for each servo.
•Fast Trim: If you often need trimming for
a function you can use a control for it.
Choose the control type [Slider <--->].
Assign the mixer output 1 of this control
to the servo channel you want to use and
lower the rate for the servo channel. You
can also assign trim to the second level
of a control and trim by using the level
switch.
•Dual Rate - for switchable servo travel: If
you want the travel of a control switch-
able you can use level switches or mixer.
Actuate the control one time for the first
variant and make the settings.
•Cross mixer for steering a tracked
vehicle with separate motors for left/right
and two ESCs: Choose channel type
Motor for left and right ESC channel.
Tip: Give them significant names e.g.
Left and Right.
Choose the control type [Normal] for
the control channel (throttle) for driving
forwards and backwards. Assign the 1.
assignment to the channel for the left
motor and 2. assignment to the right
motor. If you accelerate now (throttle up)
both tracks should drive forward. If not
switch the direction of rotation for the
servo channels with [Reverse].
For the steering control left/right also
choose the control type [Normal]. The 1.
assignment should be assigned to the left
motor, the 2. assignment to the right
motor. Only for the right motor adjust the
efficiency rate [Rate right] to -100% and
the [Rate left] to +100%. You can further
improve the driving by setting the driving
control function [Expo] to -20%, slow
down the steering with [Filter] and
decrease [Rate left / right].
Emergency off - useful if several func-
tions need to be shut off with the push of
a button e.g. drive and pump. Choose the
control type [Emerg. off] for the softkey
pair you want. You can connect up to
three servo channels with the assign-
The Zwo4 radio offers a universal and clear
concept: Each control element can
control up to three servo channels - one
servo channel can be controlled by any
number of control elements. All necessary
settings are available as presets with the
controls, therefore there is no special mixer
menu.
If you assign a few controls to one servo, the
servo channel type defines how they are
mixed. See chapter Servo - Channel Type
Typical applications:
•Mixer for controlling the rpm of a
hydraulic pump: Choose the servo
channel type [Pump -0–>] or [Pump 0–->]
for the channel that is connected to the
speed controller (ESC) of the pump
(channel type depending on your ESC,
see chapter Menu Servo). For all chan-
nels that control hydraulic valves choose
the type [Valve]. For the assigned
controls the 1. assignment should
operate the hydraulic valve, 2. assign-
ment the pump.
By changing the rate [Rate down], [Rate
up] or [Rate left], [Rate right] you adjust
how much the pump rpm increases when
operating the hydraulic valve. Do not
forget to switch the speed controller with
teach-in function off and back on. Set
´Idle´ to a value so that the pump just
starts running.
7. Mixer Functions One control for several servos

16 Mixer Functions
Actuate the control a second time together
with the level switch for the second variant
or use the function copy control at [Menu] >
[Copy control]. Choose the same channels
for both mixer outputs. You can adjust the
variants individually.

Caution: If you select a light set
template all adjustments you made
for the light controls and mixers before are
reset.
Light set with multiswitch function
Some of the common light sets need an
additional multiswitch or nautic module in
the radio. With the Servonaut HS12 there is
no need for upgrading - the necessary
channel addition is already built-in. The
radio supports Robbe/Futaba as well as
Graupner/JR - choose the servo channel 7
or 8. Connect the light set to one of these
channels. With the green menu button
[Menu] > [Multiswitch] you get to the adjust-
ment menu. See chapter Menu Multiswitch.
For a quick start there is a list of common
presets. Use presets at [Menu] > [Model] >
[Light set]. The light sets use the servo
channel 8 for the multiswitch - you may need
to replug the channel 8 in the receiver.
In the radio you can’t switch channels
7 and 8 if one of them has multiswitch
function.
Light Sets 17
Light set without
multiswitch function
Some light sets aren’t controlled via multi-
switch channels but one or two normal servo
channels. Connect the light set to the chan-
nels you want, normally channels 5 to 12.
For a quick start there is a list of common
light sets with presets at [Menu] > [Model] >
[Light set]. Choose EN for the english
presets.
Servonaut mini light sets
For mini multiswitches and mini light sets
from Servonaut you can choose between
three options:
1. Control with joysticks (standard)
•Press [Menu] > [Control] and move one
joystick. With [Reset] you can delete all
old adjustments. With [Reverse] you can
swap the joystick direction if necessary.
•To assign a channel to the control press
the blue button to get to page [2v4].
•Press [Change] and choose the receiver
channel that mini multiswitch or light set
are connected to. Leave all other adjust-
ments for control and servo channel as
they are.
