Safety Notes
Sufficient cooling is necessary to avoid
temperature problems of the ESC.
Never plug off battery from KOBY ESC as long
as motor is running.
Do not attach ESC with cable ties or similar.
Electronic parts may be damaged.
As soon as a battery and a motor are connected
to the ESC the motor may start (e.g. by
operating error or electric defect)
A motor (especially with propeller) or broken
parts can cause considerable injuries.
Use of this ESC is only permitted in situations in
which damage of objects and injuries to persons
are excluded.
Under no circumstances use a damaged ESC
(e.g. by mechanical or electric influences, by
moisture, a.s.o.). Further use may result in a
sudden failure of the ESC.
The ESC may only be supplied by NiCd, NiMH,
LiPo, LiFePo or lead batteries. A use of power
supply units is not permissible. Any contact to
the AC network is prohibited. When used with
high capacity batteries sufficient cooling must be
guaranteed.
The ESC can only be used in environments in
which no discharge of static electricity occurs.
Do not extend motor cables or battery cables.
Otherwise compliance with legal rules is not
guaranteed. Extension of cables may result in
damage of the ESC.
For current measurement, a tie meter has to be
used, since an inserted meter can damage the
ESC.
When using a BEC it is necessary to connect a
charged receiver battery with enough capacity in
parallel (see BEC). Otherwise a broken wire,
broken battery, loose of contact or a defect of
one electronic BEC part may result in total loss
of the receiver system. The system has to be
tested on ground before the first flight, to assure
that BEC capacity is sufficient for this
application.
If the Rx signal is lost the BEC switches to its
default values. After a data check the
individually programmed values are set again.

Technical data of KOBY ESCs
KOBY ESCs have a mode programming option.
Each mode installs all necessary parameters for
the respective application. Complex programming
of individual parameters is not necessary. For
adjusting single parameters use a
ProgUNIT
.
BEC data
for all KOBY ESCs:

Features of KOBY ESCs
With a KOBY ESC you purchased a high quality
product. High quality plugs (e.g. KONTRONIK
Plugs, order # 9010) as well as low resistance
soldered batteries are recommended. KOBY ESCs
are updateable online. That means you can install
the latest software versions on the ESC via a
ProgUNIT, internet connection and a PC. Please
