WATER & ELECTRONICS DON’T MIX!
Never allow water, moisture, or other foreign materials to get inside ESC, motor,
or on the PC Boards. Water damage will void the warranty!
NO SCHOTTKY DIODE!
Schottky diodes must NOT be used in Brushless-Mode or Brush-Mode with the
Goat ESC (Schottky diodes are never used with reversible ESCs, including brushless).
Schottky diode usage will damage ESC & void warranty.
DISCONNECT BATTERIES WHEN NOT IN USE
Always disconnect the battery pack from the speed control when not in use to
avoid short circuits and possible fire hazard.
4 TO 7 CELLS OR 2-CELL Li-Po ONLY
If using Ni-Cd or Ni-MH batteries, NEVER use fewer than 4 or more than 7 cells
(1.2VDC/cell) in the vehicle’s main battery pack.
If using Li-Po batteries, ONLY use a 2-cell (2S) pack for the vehicle’s main battery
& be sure the Li-Po Cut-Off programming option is turned ON.
NOVAK BRUSHLESS MOTORS ONLY
The Goat ESC is designed for use with sensor-based Novak Brushless Motors.
You may replace with Novak sensored motors down to 18.5 turns.
In Brush-Mode, you may use down to a 27-turn stock brush motor.
NO REVERSE VOLTAGE!
Reverse battery polarity can damage ESC & void warranty. Disconnect battery
immediately if a reverse connection occurs.
POWER CAPACITOR REQUIRED
An external power capacitor is installed on ESC & MUST be used. Failure to use
Capacitor 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 TRANSMITTER SUGGESTED
With the higher performance of brushless systems, undesirable radio system noise
may occur when used with lower quality transmitters (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, which can damage ESC.
NO CA GLUE
Exposure to CA glue or its fumes can cause damage to internal components of
the speed control 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 4.
• Possible receiver damage––Check operation with a different receiver.
• Possible internal damage––Refer to Service Procedures.
Throttle Stutters or Receiver Glitches During Acceleration
• Dead Band too tight––Increase ESC’s Dead Band adjustment (see Progamming sheet).
• Receiver or antenna too close to ESC, power wires, battery, or motor.
• Bad connections––Check wiring, connectors, & sensor harness.
• Low voltage to receiver––Try Glitch Buster capacitor on receiver (Novak part#5626).
• External Power Capacitor damaged/not installed––Replace Power Capacitor.
• Battery pack damaged or weak––Try a different battery pack.
• Motor’s magnet has weakened or overheated––Replace rotor.
Motor and Steering Servo Do Not Work
• Check wires, receiver signal harness wiring & color sequence, radio system, crystals,
battery/motor connectors, & battery pack.
• Power wires too close to signal wires––Do not bundle power & signal wires together.
• Possible receiver damage––Check operation with a different receiver.
• Possible internal damage––Refer to Service Procedures.
Brushless Motor Runs Backwards
• Reverse motor rotation direction––Refer to ‘Programming/Gearing’ sheet.
Speed Control Runs Excessively Hot
• Gear ratio too low––Increase gear ratio (see ‘GEAR SELECTION’).
Model Runs Slowly/Slow Acceleration
• Gear ratio too high––Reduce gear ratio (see ‘GEAR SELECTION’).
• Check battery & connectors––Try another battery; replace connectors/battery if needed.
• Incorrect transmitter/ESC adjustment––Refer to Step 4.
• External Power Capacitor damaged/not installed––Replace Power Capacitor.

AuxilliAry power OUtput
The Goat ESC features a set of power output pins for running auxiliary
cooling fans for motor or ESC cooling, or for detail items like a scale
winch or lights, and they will switch on & 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.
They are 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 polarity 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.
The Novak 30x30mm cooling fan (Novak kit #5648) is the same one that
comes with the GTB ESC, and not only fits the size of the ESC’s heat sink
perfectly, it also comes with the connector already on it to match the
pins on the Goat ESC. Fans that do not have the proper connector on
them will need a connector (one end of an old receiver input harness would
work well) put on, or will need to be soldered to the pins-- Take extra care
if attempting to solder to the fan power output pins--Do not overheat the
pins or circuit board, and do not allow any solder or wire strands to cause
a short circuit with other pins.

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.
