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.

trouble-shooting guide

Steering Channel Works But Motor Will Not Run

• Red & Green status LEDs on solid––Check input signal harness connections at ESC

and receiver. Check input signal harness wiring sequence––Refer to Step 1.

• Red status LED on solid & Green LED blinking––Check motor sensor harness connection.

Possible internal motor damage.

• Blue & Green status LEDs both blinking. Possible ESC shut-down due to locked rotor

detection––return throttle to neutral position to regain motor control––check vehicle’s

drive train for free operation.

• Blue & Red status LEDs blinking. Possible ESC thermal shut-down––Check gear ratio

& free operation of drive train for possible overloading/ESC is being severely over-

loaded––allow system to cool & return throttle to neutral position to regain motor

control. LEDs will continue to blink until system is cooled down.

• Blue & Amber status LEDs blinking. Possible motor thermal shut-down––Check gear

ratio & free operation of drive train for possible overloading/motor is being over-

loaded––allow system to cool & return throttle to neutral position to regain motor

control. LEDs will continue to blink until system is cooled down.

• Blue & Green (Locked Rotor Detection), Blue & Red (ESC Thermal Shut-Down), or Blue &

Amber (Motor Thermal Shut-Down) status LEDs blinking. ESC may have shut-down &

ESC’s neutral point is too far off to sense that transmitter throttle has been returned

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 power output pins are

on the left front edge of the PC

board--Positive (+) is on the left,

and Negative (–) is on the right.

The 3 pins behind them are for

the user-replaceable input signal

harness--Polarity of these is the

same: Positive in the middle,

Negative on the right, and input

signal is the extra pin on the left.

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.
