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.

ATTENTION: Correct gearing is essential to getting proper performance from your brushless motor system!

#55-1732P-1

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-cell li-po or 6-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
recommendations are intended to provide initial safe operation.

Decrease the pinion tooth number by 2-3 for motors without sintered rotors.

if you do not change gearing after switching to brushless, you will be

over-geared and will have slow acceleration & excessive temperatures!

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 the Havoc 8.5 motor installed, the RTR kit’s included 18-tooth pinion

gear will provide speeds above 30 mph with a 7-cell battery pack. The

23-tooth pinion gear included in the RTR kit will provide speeds above 40

mph with a 7-cell battery pack.*

Novak’s Throttle Curve adjustment

allows drivers to tailor the throttle

response of a vehicle, creating

either a quick burst of power with the

Linear Curve setting, or a smoother,

controlled low-end power delivery

with the Expo Curve setting.

Setting is fixed at “Linear” in

Brush Mode. The Throttle Curve

is selectable in Brushless Mode.

NOTE: The havoc’s software has an Auto-Detect Brush-Mode.

This feature will automatically switch the eSC from the Brushless

Throttle Profile to Brush-Mode when it does not have a brushless

motor’s sensor harness plugged into it at start-up.

The Havoc ESC reverts back to default settings when One-Touch set-up is performed.

The Havoc ESC is fully programmable, refer to page 6 for fine-tuning options.

When active (see programming on reverse side to turn ON/OFF), the built-in

Smart-Stop Li-Po Cut-Off Circuitry lets you safely use Lithium Polymer

batteries by cutting off the ESC’s throttle output when a critical safety

voltage is reached.

ESC’s factory default is Li-Po Cut-Off Circuitry Active

The circuitry constantly monitors the pack voltage. When it gets close to

the critical safety voltage (6.25V) 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 the motor again, this is not good for Li-Po batteries—reaching the

critical safety voltage too many times can damage the cells.

During power-up when ESC is switched ON, the Amber & Red LEDs

will flash together 3 times 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 very early into the run, due to the different characteristics of these batteries. To

deactivate software, see page 6.

The Havoc software lets you reverse a brushless motor’s rotation

direction (see reverse side of this sheet to select rotation). This allows

installation in vehicles with counter-rotating drive trains (or opposed

transmissions), without compromising performance. Because the ESC

will be operating in its normal forward & reverse modes, features like

Smart Braking continue to operate normally.
