You have purchased one of our new and innovative MEZON brushless model motor
controllers. This new line of controllers is based on the successful line of SPIN Pro
controllers. The MEZON controller offers progressive control combined with high
efficiency to optimize your brushless motor’s operation. The compact design which
incorporates a rugged body with integrated cooling fins helps to ensure effective heat
dissipation for cooler operation. They are equipped with overload protections for both
current and temperature. The MEZON controllers are all equipped with the EX- Telemetry
System to ensure maximum supervision and diagnostics for your model. This system, in
cooperation with the DUPLEX system, gives the modeler much greater confidence and
“peace-of-mind”. Now you can easily monitor battery capacity consumption, real-time
battery current consumption, controller temperature and other measurement data. The
MEZON controllers with integrated BEC circuits give you a powerful voltage controller
which can drive your servos directly from the flight battery, eliminating the need for a
second on-board battery. The firmware on all MEZON controllers can be easily updated by
the modeler. This means that with your PC and the USB adapter, in just a few clicks, you
can take advantage of all of the very latest updates and cool, new features. You can easily
configure all MEZON controllers with the JETIBOX universal programming tool.

EN
2.1. MEZON Controllers with BEC
The BEC version of the MEZON Controller contains a constant voltage, switching regulator
for providing current to your servos and receiver from your flight battery. The switching
regulator, also known as a switching BEC, can supply considerably higher currents than
linear BECs. The stabilized voltage level can be adjusted from 5-8V.
2. Overview
Both OPTO and BEC versions of the MEZON controller are available. The MEZON
controllers are offered in a wide spectrum from the MEZON 90 to the MEZON 165 Opto.

2.2. OPTO-Version of the Controller MEZON
The OPTO version of the MEZON Controller contains no voltage regulator (BEC) which
would provide the current for your servos and receiver from the main flight battery. This
means that a separate receiver and servo current source must be provided. With a
correctly connected OPTO controller any potential interference caused by controller
operation can not be transferred to or interfere with the receiver and servos. The incoming
and outgoing signals of OPTO controllers have no electric connection to the drive battery.
Connecting power to the RPM-output is not necessary; this output receives its power from
the throttle channel current source.

The controller should be connected to the flight battery and motor using high quality
connectors. Please see the guidelines below for proper connector installation and cable
lengths.
When you switch-on the MEZON controller, you will hear signal tones from the motor.
The tones below indicate for following conditions:
The controller has recognized a correct control pulse which complies with the STOP
(low throttle) position and is prepared to start the motor.
The controller has recognized an incorrect throttle control pulse. Check the
transmitter throttle setup to make sure that the throttle output is actually zero at
the low stick position. If necessary, reverse the throttle in your transmitter or
check your throttle throw setups.
The controller has recognized a low supply voltage. Check your battery condition
or change the controller set-up (menu “LIMITS”).

3. Connecting the Controller

EN
3.1 Soldering the Connectors
Use only new and high quality connectors and properly solder them to the cables.
We recommend bullet style connectors G4 (max. 75 A) and G5 (max. 150 A).
In order to ensure that after 1)
soldering no bare cable is exposed out of
the connector soldering cavity, remove
the cable insulation in the exact length
corresponding to the cavity depth.
2) Heat up the bare end of the cable with
the soldering iron and apply solder
around the cable circumference (“tin” the
wires). Take care to supply adequate heat.
3) Fix the connector in vertical position
(for instance, in a vice) for easier
soldering of the cable.
7

EN
4) Insert the soldering iron tip into the
cavity of the connector to be soldered and
slowly add solder. Let it flow into the
cavity. Only fill the cavity so far (not all the
way full) so that when you insert of the
tinned cable end, no solder overflows. If
you are going to solder the special “Jeti
AntiSpark” connectors, insert a male half
into the female half of the “Jeti AntiSpark”
connector when you soldier a cable to the
female connector. In this case, the male
plug will dissipate heat during soldering
and ensure that the parts already
soldered to the female will not melt.
5) Keep holding the soldering iron tip in
the connector cavity and at the same time
insert the tinned cable end. The cable is
heated by the molten solder in the
connector. The soldering iron tip can now
slowly be removed from the cavity as the
cable end is inserted.
6) The soldered connectors should be
insulated with shrink tubing.
8

EN
3.2 Cable Lengths and Connector Care
• Periodically you should inspect your connectors for cleanliness and proper connecting
force. If this force becomes too weak, replace the connector immediately. We recommend
replacing your connectors every 1-2 years of flight service time.
• The distance between the motor and the controller should not exceed 10-15 cm 4-6”).
The cable lengths to the flight battery may be lengthened up to an additional 20-25 cm
(8-10”). You can lengthen the battery cables further, if you solder, in parallel to the cables,
electrolytic capacitors (so called ESR low internal resistance capacitors with
corresponding voltage values and capacities of several hundred microfarads). Add one
capacitor for every 25 cm (10”) of additional battery cable length.
3.3 Connecting the MEZON to the JETIBOX
MEZON controllers are equipped with two, three wire cables with JR-type servo plugs. The
cable with a black plug (marked with an “RX” sticker) is NOT used for JETIBOX
communication. Only the cable with a red plug (marked with an “EXT” sticker) can be
safely connected to the JETIBOX. Power for the controller and the JETIBOX are supplied by
the flight battery when using a BEC equipped MEZON. When connecting a BEC-version, do
not forget to turn on the switch! When connecting an OPTO-version MEZON, the JETIBOX
must be powered separately.
Check to make sure that you do not accidentally have any solder or flux in any of the
connector’s moving parts. Excess flux may cause your connector to have a poor or
intermittent connection. This can be removed by washing the connector with a stiff brush
in alcohol.

EN
3.4 Connecting the MEZON to the receiver
• The red, “EXT” connector can be connected to a free receiver channel to share the BEC • •
output of your MEZON. Because you are now using two cables and two plugs the voltage
loss at high currents between BEC and receiver will be decreased.
• You can connect the red “EXT” plug to the “EXT” port in a DUPLEX EX receiver to transmit
the MEZON controller telemetry data as well as for the wireless controller setup.
When connecting a BEC equipped version do not forget to turn on the switch!
If the controller does not receive the correct control signal during its operation, it will stop
the motor.

3.5 Battery connection / disconnection procedure
For the battery and controller connections we recommend the use of the JETIMODEL Anti
Spark G5,5 connectors. We recommend soldering the AntiSpark connector to the positive
wire of the controller/battery and the customary connectors to the negative wire of the
controller/battery.
11

EN
4. Controller Set-Up
Set-up of the MEZON Controller is carried out using the JETIBOX, which serves as a
universal programming terminal with display and pushbuttons. After connecting a
device the display will show a corresponding menu. Through the use of the push-buttons
you may browse through the menus and set up the controller parameters. The changes
are carried out immediately. (You are not required to “Save” any changes.) The set-up is
stored automatically. You may connect the JETIBOX to your controller directly (see chapter
3.3) or you may do it by wirelessly when connected to a DUPLEX receiver system (see
chapter 3.4. Any set-up change to the controller can not be made if the motor is running.
In the following chapters, set-ups of particular functions are explained. Each chapter
starts with a navigation schematic which shows how to get the JETIBOX to the menu
mentioned in the chapter. It is assumed that we always start from the controller
introduction display. This is the first display shown in the JETIBOX display when you turn
on the controller.
Battery Connection Method:
1. Connect the controller’s negative terminal (normal, plain connector) to the battery’s
negative terminal.
2. Next, connect the controller’s positive terminal (Jeti “AntiSpark” connector) to the
battery’s positive terminal.
Battery Disconnection Method:
1. Disconnect the controller’s positive terminal (Jeti “AntiSpark” connector) from the
battery’s positive terminal.
2. Disconnect the controller’s negative terminal (normal, plain connector) from the
battery’s negative terminal.
Safety hint: When the flight battery is connected, handle the plane with
maximum care, always keep in mind that the propeller might start spinning.
3.6 Connecting the RPM output
The “RPM” version controller has an additional three wire lead with a connector labeled
RPM. This lead delivers an electric signal which is proportional to motor speed. This lead
can be connected to an external helicopter governor, as for example, to the Mikado Vbar.

EN
NORMAL - Basic controller setup, mostly for model airplanes
FAST RESPONSE - A very short response time when a change in the throttle input occurs.
The startup speed of the motor is set in the Acceleration menu. This setup is suited for
aerobatic competition models, for helicopters with a mix for collective blade attack
control and engine power (throttle curves), for an external governor or different
flybarless systems and multi-rotor systems. In this mode the autorotation mode can also
be used. This means that different motor startup speeds may be set in the global
acceleration menu and in the autorotation acceleration menu. The “decision point” for the
motor start-up speed is determined by the throttle signal input coming from the receiver,
see: Autorotation Setup.
CONSTANT RPM - active speed control (Governor) for helicopters. This set-up allows you
to manually set all the desired parameters. For this selection see extended set-ups.
Motor poles - Number of motor poles
Rotor gear - Main rotor gear ratio
Set MaxRotor RPM - Desired maximum rotor speed
Set MinRotor RPM - Desired minimum rotor speed
Gain - Governor gain setting. The higher this number, the faster the throttle
corrections. A lower number is displayed. If this setting is too high the throttle
control becomes unstable (similar to a high tail gyro sensitivity in helicopters).
Autorotation – activates or blocks the fast startup mode of the motor for
autorotation bail-out recovery.
Autorotation, Acceleration - activates or blocks the fast startup mode of the
motor for autorotation bail-out recovery. If the autorotation mode is activated, the motor
will have two possible startup speeds. The motor start for autorotation bail-out is a fast
spool-up (controlled by the autorotation acceleration setup), or the initial motor spool-up
controlled by the global acceleration (initial spool-up) setup. If the throttle input setting
(for throttle hold) is higher than the autorotation start point, the controller will follow the
motor spool-up settings in the autorotation acceleration setup menu when the motor re-
starts. If the throttle input setting (low throttle stick) is lower than the autorotation start
point then the motor spool-up will follow the settings in the global acceleration (initial
spool-up) setup menu when the motor re-starts.
14

EN
Example of a Helicopter Autorotation Set-Up. The global acceleration is set to an
acceleration time of 10s (from 0 to 100%). The autorotation acceleration is set to an
acceleration time of 2s (from 0 to 100%). Now we switch off the motor with a throttle
input value corresponding to motor stop (lowest throttle position). Then, when we
increase the throttle, the motor will spool back up slowly according to the global
acceleration setup since the motor was stopped with a throttle input setting that was
below the autorotation start point. If we start an autorotation (apply throttle hold) and
switch off the motor with a throttle input value which stops the motor but is still above
the autorotation start point, the motor will spool-up up quickly when the throttle is
restored (release throttle hold). This effectively creates a “window” just above the
initialization point which allows the autorotation acceleration to “arm”.
Acceleration
This is the (global) acceleration rate for the motor. A good basic rule is: the larger the
propeller or rotor diameter, the longer the acceleration value must be. For large
outrunners, apply an acceleration time of 2 or more seconds. For model helicopters we
recommend acceleration times of 5 seconds or more.
Brake
Here you can select from several predefined brake setups or you may define your own
brake. The first value is the brake effect starting strength in %, the second value
represents the brake effect final strength in %, the third value shows the braking time
between the first and second intensity.

Init Point Type - AUTO: In this mode the Mezon will automatically set the initial point
based upon what it detects as the low throttle position when the ESC/receiver are
switched on. This happens within the first half second once the ESC is powered.
(Recommended)
Init Point Type - FIXED: In this mode you can set the Initial(arming) and End Points as
fixed values in ms. The Initial Point and End Point positions are displayed only when the
FIXED Init Point Type is selected.
Initial Point – This is the user defined value of the initial point. If the selected value is
lower than the actual throttle value, the controller/motor will sound an error tone.
End Point – This is the defined full throttle position value.
Note - For safety reasons, the “Init Point” and “End Point” can be only changed if the
controller does not receive any signal from the receiver. If a control signal is detected no
changes can be made.
AutoInc EndPoint – The automatic extension of the range when the End Point position
pulse width exceeds the defined value.
Fixed End Point – User defined, fixed END POINT position value for 100% throttle.
Overstepping this value has no effect as the throttle output is already at 100% (regardless
of stick position).
Default setting – By pressing and holding either the left/right key in this screen resets
the controller to its default settings.

Acumulator type – Here is where you select your flight battery type:
NiCd/NiMh – the cut-off voltage can be set according to your desired minimum single
cell voltage.
LiIon/LiPol – Here you can either allow your Mezon to automatically detect the number
of cells (this is useful if you are using packs with different cell counts), or you can specify
the number of cells. For LiFe packs we do not recommend the automatic cell selection,
instead, you should specify the number of cells. The last setup choice within this cell type
is the setting for the minimum voltage per cell.
Direct – Here you can simply enter a cut-off voltage directly without selecting any
battery type.
Alarm voltage – Here is where you set the alarm level where the low voltage alarm is
activated.
Temp. Protection – This is for the set-up of any temperature protection. If the ESC
temperature exceeds the selected temperature protection value, the selected motor cut-
off starts and the high temperature alarm is activated. The temperature alarm starts
signaling when the ESC temperature is 10 degrees below the selected temperature
protection value.
Max. bat. Capac. – Setting for the maximum flight battery capacity usage. If the
capacity used exceeds the selected value, the selected motor cut-off starts. It is possible to
select NO LIMIT in this menu.
Capacity alarm - Setting for the alarm activation level if battery capacity usage is
exceeded.
Max. batt Current – Setting for the current protection. If the actual current draw exceeds
the selected current value, the Mezon actively limits the current draw and the high
current alarm is activated .
Cutoff type – Motor power limiting mode.
