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.
TIMING INCREASES ELECTRONICS’ TEMPERATURES
Use extreme caution when setting up and testing your application to avoid overloading and
overheating the Havoc Pro SC and brushless motor. Excessive overheating will void warranty!
SENSOR-BASED BRUSHLESS MOTORS ONLY
The Havoc Pro SC is designed for use with sensor-based Novak Brushless Motors. You may
replace with Novak sensored motors down to 3.5T (540-size) or 4.5T (550-size).
TIMING PRODUCES DANGEROUSLY HIGH SPEEDS
When Novak’s advanced timing is activated, the resulting vehicle speed can be
dangerously high. It is important to take extra precautions.
NO SCHOTTKY DIODES!
Schottky diodes are never to be used with brushless ESCs.
Do not use Schottky diodes with Havoc Pro SC 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.
2S LiPo/LiFe OR 4-6 NiMH CELLS ONLY
If using LiPo or LiFe battery packs, use a 2-cell (2S) pack for the vehicle’s main battery & be
sure the Voltage Cut-Off programming option is turned
ON
(refer to Track Guide).
If using NiCd or NiMH batteries, NEVER use more than 6 cells (1.2VDC/cell) in the vehicle’s
main battery pack, and disable Voltage Cut-Off Circuitry
(refer to Track Guide)
.
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 2S Power Trans-Cap module is installed on ESC & MUST be used at all times.
Failure to use a Novak Power Trans-Cap module with the proper cell rating will result in
higher ESC 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 LiPo/LiFe BATTERIES SUGGESTED
Using LiPo/LiFe 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. 2.4GHz radio system use is best. An
FM system is acceptable, as long as it is high quality. AM systems are
NOT
recommended.
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 the ESC.
NO CA GLUE
Exposure to CA glue or its fumes can cause damage to internal components of the ESC
and result in premature failure.

VOLTAGE cUt-OFF circuitry
When active
(see Track Guide to turn ON/OFF)
, the built-in Novak Smart-Stop Voltage
Cut-Off Circuitry lets you safely use 2S Lithium Polymer (LiPo) or Lithium Iron
Phosphate (LiFe) battery packs by cutting off the speed control’s throttle output
when the critical safety voltages are reached.
The circuitry constantly monitors the pack voltage and automatically selects a 2S
cut-off voltage value
[6.25V (2S) LiPo; 4.75V (2S) LiFe]
.
When the ESC detects
that the critical safety voltage value will soon be reached,
it begins interrupting,
or “blipping,” the throttle output as an early warning that the battery’s voltage is
getting low and the throttle output will soon be completely shut off.
When the critical voltage is reached, the throttle output to the motor gets completely
shut down to keep the voltage from dropping further
(Red & Green LEDs will
alternately flash & you still have steering control)
.
Re-charge battery after Smart-Stop circuitry shuts off throttle
Even though the pack’s voltage will rise
(after a short resting period)
to a level high
enough to run motor again, this is not good for LiPo or LiFe batteries.
Reaching critical safety voltage too many times can damage the cells.
DO NOT CONTINUE TO RUN VEHICLE AFTER THE SMART-STOP HAS SHUT
DOWN THE THROTTLE OUTPUT THE FIRST TIME.
When the ESC is switched ON, the Yellow & Red LEDs will flash together 3
times to indicate LiPo/LiFe Cut-Off is
ACTIVE
.
With the Voltage Cut-Off turned ON & using NiCd or NiMH cells, the circuitry will shut off
the ESC’s throttle output very early into the run, due to the different characteristics of these
batteries. Change the ESC’s Cut-Off Circuitry mode to OFF to use these batteries.
