ATTENTION: Correct gearing is essential to getting proper performance from your brushless motor system!
4-2010
P R OPER G E A R S E L E C T I O N
Motor operating temperature is the ONLY
way to properly set the vehicle gearing
The motor should be 160-175°F MAX at end of run!
Change the gearing to avoid overheating.
DO NOT FREE REV OR OPERATE WITHOUT LOAD!
General Gearing for 2 & 3-cell Li-Po or 6 & 9-Cell Ni-MH Use:
These recommendations are for sport or entry level setups. Stock radio equipment
and sport “stick-type” battery packs should work safely. These gearing range
recommendations are intended to provide initial safe operation.

The Havoc 3S’s included fan is required when using a 3S Li-Po battery pack.
If you do not change gearing after switching to brushless, you will be
over-geared and will have slow acceleration & excessive temperatures!
With the broad brushless power band, you can go 1-2 teeth higher pinion than listed
above for more top speed, but remember going higher will produce excessive ESC & motor
heating. Check the motor’s operating temperature after making any gearing adjustments-
-motors are designed to operate from 160ºF-175ºF. If you do overheat your ESC and
motor, be sure to allow it to cool for several hours and install a smaller pinion gear.

Decrease the pinion tooth number by 2-3 for motors without sintered rotors.
PINION GEAR
w/ 2S
FOR RTR KITS:
Most car kits include a pinion gear that is generally sized for mild motors and is
fairly large. To be safe, replace the installed pinion gear with one that is about 3
to 5-teeth smaller. Most stock spur gears are safe to use.
FOR TRAXXAS® SLASH™:
With a Novak 8.5-turn brushless motor installed, the RTR kit’s included 18-tooth
and 23-tooth pinion gears will provide speeds above 40 mph with various
battery packs. For more specific speed run information and tips to reaching
higher speeds, please visit the Novak Web site.

a quick burst of power with the

This ESC is compatible with 2-3S Li-Po or 4-9 Ni-MH cells. Novak’s exclusive
Smart-Stop Li-Po Cut-Off Circuitry is built-in and when active (see program-
ming on reverse side to turn ON/OFF), it automatically switches to the proper
Li-Po cut-off voltage for the battery packs you connect.
ESC’s factory default is ON for Li-Po Cut-Off Circuitry
This circuitry lets you safely use 2S or 3S Lithium Polymer battery packs by
cutting off the speed control’s throttle output when a critical safety voltage
is reached (6.25V for 2S and 9.375V for 3S).
The circuitry constantly monitors the pack voltage. When it gets close to
the critical safety voltage 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
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
high enough to run the motor again, this is not good for Li-Po batteries.
Reaching the critical safety voltage too many times can damage the cells.
(after a short resting period)
DO NOT CONTINUE TO RUN VEHICLE AFTER THE LI-PO CUT-OFF
HAS SHUT DOWN THE THROTTLE OUTPUT FOR THE FIRST TIME.
During power-up when the ESC is switched ON, the Amber & Red LEDs will flash
together 2 times for 2S or 3 times for 3S packs to indicate Li-Po Cut-Off is ACTIVE.
With the Li-Po Cut-Off turned ON & using Ni-Cd or Ni-MH cells, the circuitry will shut off the ESC’s
throttle output, due to the different characteristics of these batteries. To deactivate software, see page 6.

NOTE: The Havoc 3S has the ability to run on either two or three-cell Li-Po
batteries via Novak’s auto detect software. When Li-Po circuitry is active
(see programming on reverse side to turn ON/OFF), it automatically switches
to the proper Li-Po cut-off voltage for the battery packs you connect.

PLEASE NOTE: This page contains optional Advanced Programming items!
(But don’t worry, you can always reset factory defaults by performing the One-Touch programming again, so go ahead & experiment—that’s why the programming is in there, right?)
HAVOC 3S ESC SOFTWA R E F L O W C H A R T
The Havoc 3S ESC features nine parameters that can be adjusted.
Transmitter can be either ON or OFF:
1. IF TRANSMITTER IS OFF, DISCONNECT ESC FROM RECEIVER
Remove input signal harness from the receiver to avoid radio interference.
2. CONNECT ESC TO A CHARGED BATTERY PACK
3. SLIDE ESC’s ON/OFF SWITCH TO ‘ON’ POSITION
4. WITH ESC AT NEUTRAL PRESS & HOLD ESC’S SET BUTTON
Release ESC’s SET button once LED is at desired setting.
To skip a parameter, press and hold ESC’s SET button to the desired parameter.
5. SELECT PARAMETER VALUE
LED flashes to indicate active setting (refer to tables at right). Quick press & release
SET button to select desired setting.
6. PRESS & HOLD SET BUTTON TO STORE SELECTION
When SET button is pressed and held for about 1 second, the new selection is
stored in ESC’s memory—The 4 status LEDs will scroll across to indicate ESC is exiting
programming and ESC returns to neutral.
Note: There is no time constraint during selection process of custom parameters.
