The Havoc ESC is equipped with internal protection. The following is a list of
error codes depicted through LEDs––most flash when throttle is applied.
• All status LEDs scroll from left to right––Blue sensor harness wire disconnected or motor
does not have temperature protection––Replace blue sensor harness wire or use motor
with temperature protection. Check Novak Web site for motor compatibility list.
• 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.
• Green & Red status LEDs on toggle––Li-Po Cut-Off triggered—Replace or charge
battery. Battery voltage may be too low.
• 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.
T R A N S M I T T E R A D J U S T M E N T S
If you have any problems with Step 4, adjust transmitter as follows and then
repeat One-Touch programming in Step 4:
A. Set HIGH ATV or EPA to 100%.
[amount of throw at full throttle]
B. Set LOW ATV, EPA, or ATL to 100%.
[amount of throw at full brakes]
C. Set EXPONENTIAL to zero setting. [throttle channel linearity]
D.
Set THROTTLE CHANNEL REV. SWITCH to either position.
E. Set THROTTLE CHANNEL TRIM to middle setting.
[adjusts neutral position/increases or decreases coast brakes]
F.
Set ELECTRONIC TRIGGER THROW ADJUSTMENT
brake throw--best for reversible ESCs.

The Havoc ESC has an internal 6V/1.5A BEC, so a receiver battery pack is
unnecessary. If you would like to use a receiver battery pack or external BEC,
please follow these steps to ensure normal operation:
1. Connect receiver battery pack/external BEC into battery slot of the receiver.
Receiver battery pack/BEC should have an ON/OFF switch installed.
2. Leave the ESC’s input harness intact. First turn the receiver battery pack ON,
then cycle the ESC’s switch from ON to OFF. The ESC power will remain on
even though the switch is OFF.
After running your vehicle, simply turn OFF receiver battery pack/external BEC.
Always disconnect main battery pack when vehicle is not in use.

Should any of the sensor harness 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 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.

HAVOC SPORT DESIGNED FOR NOVAK BRUSHLESS MOTORS
This ESC is designed for Novak Thermally Protected Sensor-Based Brushless Motors!
ESC will ONLY operate if motor is replaced with a sensor-based motor (down to 8.5T)
that has built-in thermal protection. Check Novak Web site for motor compatibility.
Never allow water, moisture, or other foreign materials to get inside ESC, motor, or on
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!
Always disconnect batteries from ESC to avoid short circuits and possible fire hazard.
If using LiPo batteries, ONLY use a 2-cell (2S) pack for vehicle’s main battery & be sure
the LiPo Cut-Off option is turned ON (refer to page 6). For NiCd or NiMH batteries,
NEVER use fewer than 4 or more than 7 cells (1.2VDC/cell) in the main battery pack.
Using LiPo batteries that cannot supply the required current of this system will result in ESC,
or motor, or battery damage, and will void the warranty. We suggest 25C rating minimum.
Reverse battery polarity can damage ESC & void warranty. Disconnect battery
An external power capacitor is installed on ESC & MUST be used. Failure to use Capacitor will result
Always turn the transmitter on first so you have control of the vehicle when it turns on.
