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.
SENSOR-BASED BRUSHLESS MOTORS ONLY
Designed for use with 540 & 380-size sensor-based Novak brushless crawler motors.
For optimal Rock Boost performance, earlier Novak Ballistic Crawler motors will need to
have the mechanical timing of the motor set to 0°
--Loosen bearing cap & adjust timing to
where the sensor harness connector is directly in-line with the center
(Phase B)
solder tab.
NO SCHOTTKY DIODES!
Do not use Schottky diodes with 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!
2S LiPo/LiFe OR 4-7 NiMH CELLS ONLY
NEVER exceed 2S LiPo/LiFe packs--Be sure Voltage Cut-Off option is turned
ON
(refer to
Field Guide)
. For NiCd/NiMH, NEVER exceed 7-cells
(1.2VDC/cell)
& disable Voltage Cut-Off.
DISCONNECT BATTERIES WHEN NOT IN USE
Always disconnect batteries from ESC to avoid short circuits and possible fire hazard.
POWERCAP REQUIRED
An external PowerCap is installed on ESC & MUST be used at all times. Failure to use
Novak PowerCap will result in higher ESC temperatures & possible damage.
GOOD QUALITY LiPo/LiFe BATTERIES SUGGESTED
Using LiPo/LiFe batteries that cannot supply the amperage required by this system will
result in possible battery, ESC, & motor damage, and will void the warranty.
TRANSMITTER ON FIRST
Turn on transmitter power first so you will have control of vehicle when you turn it on.
GOOD QUALITY RADIO SYSTEM 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.
DO NOT BUNDLE POWER & SIGNAL WIRES TOGETHER
RF noise in the power wires can adversely effect radio system performance.
INSULATE WIRES & NO REVERSE VOLTAGE!
Insulate exposed wiring with heat shrink tubing or electrical tape to prevent short circuits,
& never reverse connect the battery--ESC damage will occur & void warranty.
NO CA GLUE
CA glue or fumes can damage internal components of ESC & cause premature failure.

PRECAUTIONS
ACCESSORIES
VOLTAGE cUt-OFF circuitry
When active, the built-in 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 ESC’s throttle output when the critical safety voltage is reached.
The circuitry monitors the battery voltage and automatically cuts-off the ESC’s
throttle when the voltage drops to
6.25V for 2S LiPo, or 4.75V for 2S LiFe
. As the
ESC approaches the critical safety voltage, it begins interrupting, or “blipping” the
throttle output as an early warning that the voltage is getting low and the throttle
output will soon be completely shut off. When the critical voltage is reached, the
ESC’s throttle output 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, this is not good for LiPo or LiFe batteries.
Reaching critical safety voltage too many times can damage the cells.
DO NOT RUN VEHICLE AFTER SMART-STOP HAS SHUT DOWN THROTTLE OUTPUT!
When the ESC is switched ON, the Yellow & Red LEDs will flash
together 2 times to indicate LiPo/LiFe Cut-Off is
ACTIVE
.
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.
OPTIONAL RECEIVER PACK USAGE
To use an external receiver battery pack to power the electronics:
1.
Plug the 5 cell (1.2VDC/cell) receiver pack into the battery slot of the receiver.
2.
Switch the receiver pack ON. Next, turn the ESC’s switch ON, then OFF to
allow the ESC to be powered by the external power source.
3.
Turn the receiver pack’s switch OFF to turn the vehicle OFF.
ALTERNATIVE METHOD
1.
Plug the 5 cell (1.2 VDC/Cell) receiver pack into the battery slot of the receiver.
2.
Unplug the ESC’s red wire from input receiver harnesse (insulate the red wire).
3.
To turn the vehicle ON, switch the receiver pack ON. Then, turn the ESC’s switch ON.
4.
To turn vehicle OFF, turn ESC’s switch OFF, then turn receiver pack’s switch OFF.
