WATER & ELECTRONICS DON’T MIX!
Allowing water, moisture or other foreign materials to get inside ESC will void warranty.
MuST bE 14 yEARS OR OLDER TO OpERATE
This product is not a toy and is not intended for use by children under 14 years of age
without the strict supervision of an adult.
NO SCHOTTKy DIODES!
Schottky diodes are never used with reversible ESCs, including brushless.
Do not use Schottky diodes with Goat 3S ESC!
DO NOT FREE REV OR OpERATE WITHOuT LOAD!
This includes running the motor without a pinion or holding the car in the air and
running the motor at or close to full power. Free revving will void the warranty!
DISCONNECT bATTERIES WHEN NOT IN uSE
Always disconnect batteries from ESC to avoid short circuits and possible fire hazard.
2-3 CELL Li-po OR 4 TO 9 CELLS ONLy
If using Li-Po batteries, use a 2 or 3 cell (2-3S) pack for the vehicle’s main battery & be
sure the Li-Po Cut-Off programming option is turned ON (refer to page 6).
If using Ni-Cd or Ni-MH batteries, NEVER use more than 9 cells (1.2VDC/cell) in the
vehicle’s main battery pack, and disable Li-Po Cut-Off.
NOVAK bRuSHLESS MOTORS ONLy
The Goat 3S is designed for use with sensor-based Novak Crawler Brushless Motors. You
may replace with Novak sensored motors down to 13.5T (2S) & 18.5T (3S).
In Brush Mode, you may use brushed motors down to 27T (2S) & 33T (3S).
NO REVERSE VOLTAGE!
Reverse battery polarity can damage ESC & void warranty. Disconnect battery
immediately if a reverse connection occurs.
pOWER TRANS-CAp MODuLE REQuIRED
An external 3S power trans-cap module is installed on ESC & MUST be used at all times. Failure to
use Trans-Cap module will result in higher temperatures & possible thermal shut-down or damage.
TRANSMITTER ON FIRST
Always turn on the power of the transmitter first so that you will have control of the
vehicle when you turn it on.
GOOD QuALITy Li-po bATTERIES SuGGESTED
Using Li-Po batteries that cannot supply the amount of current required by this system
will result in possible battery pack, ESC & motor damage, and will void the warranty. It
is recommended to use a 25C or higher rating.
GOOD QuALITy RADIO SySTEM SuGGESTED
With the higher performance of brushless systems, undesirable radio system noise may
occur when used with lower quality radio systems (like some RTR radios).
DO NOT buNDLE pOWER & SIGNAL WIRES TOGETHER
RF noise in the power wires can adversely effect radio system performance.
INSuLATE WIRES
Always insulate exposed wiring with heat shrink tubing or electrical tape to prevent short circuits.
NO CA GLuE
Exposure to CA glue or its fumes can cause damage to internal components of the ESC
and result in premature failure.

product warranty
The Goat 3S Brushless/Brush ESC is guaranteed to be free from defects in materials or workmanship for a period of 120 days from
the original date of purchase
(verified by dated, itemized sales receipt)
. Warranty does not cover incorrect installation, components
worn by use, damage to case or exposed circuit boards, damage from using more than 9 cells
(1.2 volts DC/cell)
or more than 3
Li-Po cells input voltage, damage resulting from using Li-Po batteries without Smart-Stop circuitry active,

overheating solder tabs, reverse voltage application, improper use or installation of external BEC, damage from not removing the
red wire from the ESC’s input harness, damage resulting from thermal overload or short-circuiting motor (or connecting a brushless
motor sensor harness while operating in Brush-Mode), damage from incorrect installation of FET servo or receiver battery pack,
damage due to free revving motor, damage due to using a non-Novak motor, a non-sensored motor or a motor lower than
18.5 turns with 3S Li-Po, not using or incorrect installation of a Trans-Cap module--3S on the ESC or from using a damaged
Trans-Cap module--3S, using a Schottky diode, using non-Novak Trans-Cap module--3S or motor, splices to input, ON/OFF
switch, or sensor harnesses, damage from excessive force when using the One-Touch/SET button or from disassembling case,
tampering with internal electronics, allowing water, moisture, or any other foreign material to enter ESC or get onto the PC board,
incorrect installation/wiring of input plug plastic, allowing exposed wiring or solder tabs to short-circuit, or any damage caused by
a crash, flooding or natural disaster.
Because Novak has no control over the connection & use of the speed control or other related electronics, no liability may be assumed
nor will be accepted for any damage resulting from the use of this product. Every Novak speed control & motor is thoroughly tested
& cycled before leaving our facility and is, therefore, considered operational.
By the act of connecting/operating speed control, user
accepts all resulting liability.
In no case shall our liability exceed the product’s original cost. We reserve the right to modify warranty
provisions without notice. This product is not intended for use by children under 14 years of age without the strict supervision of
an adult. Use of this product in an uncontrolled manner may result in physical damage or injuries—take extra care when operating
any remote control vehicle. Designed by Novak Electronics, Inc. in Irvine, CA and assembled with globally sourced components.

cooling fan installation
the included novak 30x30x6mm clear cooling fan (novak kit #5648) is
required for the Goat 3s when using a 3-cell li-po pack.
In addition, the
fan comes with the connector already on it to match the pins on the Goat 3S.
The Goat 3S ESC features a set of power output pins for running auxiliary cooling
fans, so you can add fans to the motor, the ESC or both, and they will switch on
and off with the ESC’s power switch. These pins output 6.0 VDC
(same as the
BEC)
, so you will get maximum output from cooling fans without over powering
them by running directly from the battery pack’s voltage.
The pin-out label located on the
front lower section of the ESC’s
case
(under the pins, push button,
& LEDs)
shows the polarity of the
power output pins.
The 2 pins on the front edge of
the circuit board--Positive (+) is
on the left, and Negative (–) is on
the right.
The set of 3 pins behind
them are for the user-replaceable
input signal harness—The polar-
ity of those is the same: Positive
in the middle, Negative on the
right, and the extra pin on the
left is for the input signal.
Should any of the 26G Teflon wires pull out of the connector on the end
of the motor’s sensor harness, re-insert them in the appropriate slot in the
connector as shown below. There is a small plastic tab that grabs a small
raised barb on the back of the metal socket crimped onto the Teflon wire’s
end. The plastic tab should be checked to make sure it has not deformed
excessively before inserting the metal socket into the plastic connector
housing with the barb toward to plastic tabs.
If the motor’s
sensor harness
gets damaged,
please contact
our Customer
Service Dept.
