ACCESSORIES
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
Strict adult supervision is required for use by children under 14 years of age.
ESC HAS THERMAL OVERLOAD PROTECTION
Heavy BEC loading may trigger protective circuitry!
SENSOR-BASED BRUSHLESS MOTORS ONLY
Designed for use with any 540-size (or 4.5T or higher 550-size) sensor-based brushless motors.
NEVER USE SCHOTTKY DIODES WITH BRUSHLESS ESCs!
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!
1S-2S LiPo OR 4-6 NiMH CELLS ONLY
NEVER exceed 2S LiPo for vehicle’s main battery & be sure Voltage Cut-Off option is ON.
NEVER exceed 6-cell NiCd/NiMH (1.2VDC/cell), & disable Voltage Cut-Off Circuitry.
GOOD QUALITY RADIO & LiPo BATTERIES SUGGESTED
Undesirable radio noise may occur when using lower quality radio systems. 2.4GHz radio
system use is best; high quality FM system is acceptable; AM systems are NOT recommended.
LiPo’s that can’t supply the required amperage can damage electronics & voids warranty.
UNPLUG BATTERY WHEN NOT IN USE & SWITCH ESC OFF
Always disconnect the battery from ESC to avoid short circuits and possible fire hazard.
ALWAYS SWITCH OFF ESC BEFORE CONNECTING BATTERY
If battery is connected with ESC switch in ON position, serious damage can occur.
DO NOT CHANGE BATTERY WIRE COLORS
Avoid the risk of improper power connection that will damage ESC & voids warranty.
TRANSMITTER ON FIRST
Turn on transmitter power first so you will have control of vehicle when you turn it on.
NO REVERSE VOLTAGE!
Reverse battery connection will damage ESC immediately & will void the warranty !
Insulate exposed wiring with heat shrink tubing or electrical tape to prevent short circuits.
GLITCH BUSTER SUGGESTED / BUILT-IN POWERCAPS
The built-in PowerCaps on ESC MUST be retained to avoid high ESC temperatures &
possible damage. Use of the included Glitch Buster helps with heavy BEC loading.
DO NOT BUNDLE POWER & SIGNAL WIRES TOGETHER
RF noise in the power wires can adversely effect radio system performance.
NO CA GLUE
CA glue or fumes can damage internal components of ESC & cause premature failure.
PRECAUTIONS
When active, the built-in Smart-Stop Auto-Detect Voltage Cut-Off Circuitry lets you
safely use 2S Lithium Polymer (LiPo) battery packs by cutting off the speed control’s
throttle output when the battery’s critical safety voltage is reached.
This circuitry monitors battery voltage and automatically selects a 2S cut-off voltage
value when using a 2S battery pack. When the ESC detects that the critical safety
voltage value will soon be reached, it begins cutting back the throttle output level
to prevent the battery’s voltage from reaching the a level that results in cell damage.
When the critical voltage is reached, the throttle output to the motor gets
completely shut down to keep the voltage from dropping further. (Red & Yellow
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, reaching critical voltage too many times will damage cells.
DO NOT RUN VEHICLE AFTER SMART-STOP HAS SHUT DOWN THROTTLE OUTPUT!
With the Voltage Cut-Off turned ON & using NiCd/NiMH cells, the ESC’s throttle output will
shut off very early into the run--Change the Cut-Off Circuitry mode to OFF to use these batteries.
See CUSTOM PROGRAMMING OPTIONS on ESC Track Guide to properly adjust this setting.
RECEIVER PACK USAGE
NOVAK HIGHLY-RECOMMENDS the use of an external receiver battery pack
to supply power to the electronics when using high-power servos, as these
servos put excessive load on the speed control’s internal BEC.
Using an external reciever pack will greatly increase life span of
your ESC, as this is a leading cause of speed control failure.
To use an External Receiver Battery Pack to Power the Electronics:
1. Plug the 5 cell (1.2 VDC/Cell) receiver battery pack into the battery slot (or any
open/unused channel) of the receiver.
2. Remove the red wire from ESC’s input receiver harness (insulate the red wire).
3. To turn the vehicle ON, switch the receiver pack’s power switch ON. Then, turn
the ESC’s power switch ON.
4. To turn vehicle OFF, turn ESC’s switch OFF, then turn receiver pack’s switch OFF.

ONE-YEAR product warranty
This Brushless ESC is guaranteed to be free from defects in materials or workmanship for a period of one year from
original purchase date (verified by dated, itemized sales receipt). Warranty does not cover incorrect installation,
components worn by use, damage to case or exposed circuit boards, damage from using more than 6 cells (1.2
volts DC/cell) or more than 2 LiPo cells input voltage, damage resulting from using LiPo batteries without Smart-
Stop voltage cut-off circuitry active, using insufficient LiPo batteries that cannot supply the amperage required
by this system, damage resulting from thermal overload or excessive BEC loading or disabling Thermal Protection
Circuitry, overheating solder tabs, cross-connection of battery/motor power wires, reverse voltage application,
improper use or installation of external BEC, damage from incorrect installation of FET servo or receiver battery
pack, damage due to free revving motor, damage due to short-circuiting motor or using a non-Novak motor or
a non-sensored motor, removal of facotry-installed PowerCaps, incorrect installation of a PowerCap or operating
ESC with damaged PowerCaps, using a Schottky diode, splices to input, ON/OFF switch, or sensor harnesses,
replacing power wires with all same color wires, damage from excessive force when using the One-Touch/SET
button or from disassembling case, tampering with internal electronics, allowing water, moisture, or any other
foreign material to enter ESC or get onto the PC board, incorrect installation/wiring of input plug plastic, allowing
exposed wiring or solder tabs to short-circuit, or any damage caused by a crash, flooding, or natural disaster.
Because Novak has no control over connection & use of ESC or other related electronics, no liability may
be assumed nor will be accepted for any damage resulting from the use of this product. Every Novak ESC
& motor is thoroughly tested & cycled before leaving our facility and is, therefore, considered operational.
By the act of connecting/operating ESC, user accepts all resulting liability. In no case shall our liability
exceed the product’s original cost. We reserve the right to modify warranty provisions without notice.
This product is not intended for use by children under 14 years of age without the strict supervision of an
adult. Use of this product in an uncontrolled manner may result in physical damage or injuries—take extra
care when operating any remote control vehicle. Melted ESCs/motors are not covered by the warranty.
