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
to neutral––Refer to Step 5.
• Possible receiver damage––Check operation with a different receiver.
• Possible internal damage––Refer to Service Procedures.
Receiver Glitches/Throttle Stutters During Acceleration
• Receiver or antenna too close to ESC, power wires, battery, or motor.

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.
