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.

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”).

3.1 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.

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.

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.
