The Ultimate Micro-Rock Crawler for Brushless & Brush Motors and Full Programmability!
The Mongoose Crawler electronic speed control gives you the best of everything--Sensor-based brushless motor control, world
class brush motor performance with Auto-Detect Brush-Mode, complete on-board programming of Minimum Brake, Drag/Hill
Brake, Dead Band, Li-Po Cut-Off, Motor Rotation and Drive Frequency (in Brush Mode) ... all packed into a micro-sized crawler!
The Mongoose Crawler is factory-loaded with 4 throttle programs to choose from (including a Servo/Robotic mode) , Novak’s Crawler-exclusive brushless holding
power & linear ramp-up braking , Thermal Overload Protection, high-power B.E.C. for extra-strong/fast servo response, Polar Drive & Digital Anti-Glitch circuit-
ries for cool and smooth operation, auxiliary fan power output, and Radio Priority circuitry for the ultimate in control, right down to the end of the charge. Add
to this the user-replaceable battery wires, power capacitor and input harness, and the Mongoose Crawler has it all!
To benefit from all of the technical features of the Mongoose Crawler, PLEASE READ ALL INSTRUCTIONS BEFORE OPERATION
WATER & ELECTRONICS DON’T MIX!
Never allow water, moisture or other foreign materials to get inside ESC, motor
or on the PC Boards. Water damage will void the warranty!
NOVAK BRUSHLESS MOTORS ONLY
The Mongoose Crawler is designed for use with sensor-based Novak Three-80 Crawler
Motors (18.5T minimum). Any motor used must have Thermal Overload Protection. Check
the Novak Web site for motor compatibility. Using a Novak Three-80 motor (Novak #3450-
3452) is acceptable, but the ESC will default to the Mongoose non-crawling default profile.
DISCONNECT BATTERIES WHEN NOT IN USE
Always disconnect the battery pack from the speed control when not in use to
avoid short circuits and possible fire hazard.
2-3 CELL LI-PO ONLY OR 4 TO 9 CELLS
If using Li-Po batteries, ONLY use a 2-cell (2S) or 3-cell (3S) pack for the vehicle’s
main battery & be sure the Li-Po Cut-Off programming option is turned ON.
If using Ni-Cd or Ni-MH batteries, NEVER use fewer than 4 or more than 9 cells
(1.2VDC/cell) in the vehicle’s main battery pack.
NO SCHOTTKY DIODE!
Schottky diodes must NOT be used in Brushless-Mode or Brushed-Mode with the
Mongoose Crawler (Schottky diodes are never used with reversible ESCs, including brushless).
Schottky diode usage will damage ESC & void warranty.
NO REVERSE VOLTAGE!
Reverse battery polarity can damage ESC & void warranty. Disconnect battery
immediately if a reverse connection occurs.
POWER CAPACITOR REQUIRED
An external power capacitor is installed on ESC & MUST be used. Failure to use
Capacitor may result in higher 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 TRANSMITTER SUGGESTED
With the higher performance of brushless systems, undesirable radio system noise
may occur when used with lower quality transmitters (like some RTR radios).
The current transmitter that is included in the Losi
®
Mini Rock Crawler™—LSR-3000
DSM Transmitter: MLST2—is acceptable to be used with the Mongoose Crawler.
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 (Novak #5850/#5851) or
electrical tape to prevent short circuits, which can damage ESC.
NO CA GLUE
Exposure to CA glue or its fumes can cause damage to internal components of
the speed control and result in premature failure.

Crawler™.
•NOT ALL TRANSMITTERS HAVE THESE ADJUSTMENTS•
The Mongoose Crawler has a user-replaceable input harness with the industry-
standard receiver connector on it & works with all major radio brand’s new
receivers (Refer to Figure 1 to see how to connect the included user-replaceable input
harness to the MRX-3000 DSM Receiver in the Losi
®
Mini Rock Crawler™). However,
some very old receivers must have the wiring sequence in the plastic 3-pin JST
connector housing changed on the receiver end. This is important, as the receiver
& servo electronics may be damaged if the sequence is incorrect.
For example, Airtronics Z receivers have blue plastic cases and new KO cases
have tabs on the input harness openings. Old Sanwa/Airtronics cases are black
in color and old KO cases do not have tab openings.
For instructions on changing the wiring sequence for older receivers, visit the
Novak Web site.

step 1 – connect input harness
1. MOTOR CAPACITORS NOT NEEDED
Novak brushless motors do not require external motor capacitors.
2. DO NOT USE SCHOTTKY DIODES
Schottky diodes must NOT be used with reversible ESCs (including brushless).
Schottky diode usage will damage the ESC & void warranty.
3. FACTORY-INSTALLED POWER CAPACITOR REQUIRED
The factory-installed Power Capacitor MUST be used with brushless & brush-
type motors. If Power Capacitor becomes dented or damaged, ESC failure can occur—replace
immediately (Novak #5683). Longer Power Capacitor wires will decrease performance.
4. CONNECT ESC’S MOTOR PHASE WIRES TO MOTOR
The Mongoose Crawler comes with high quality 2mm low-loss power
connectors on the motor wires. Connect the ESC’s power phase wires to
the matching color motor power wires.
a . Connect the BLUE ESC power wire to the BLUE motor wire.
b . Connect the YELLOW ESC power wire to the YELLOW motor wire.
c . Connect the ORANGE ESC power wire to the ORANGE motor wire.
Additional 2mm power connectors available in Novak accessory kits (Novak #5721).
5. CONNECT MOTOR’S SENSOR HARNESS TO ESC
Insert the 6-pin connector on the end of the motor’s Teflon sensor wires
into ESC’s sensor harness socket--the connector is keyed and will only go
together in one direction.
6. CONNECT SPEED CONTROL TO BATTERY PACK
Connect speed control’s BLACK and RED power wires to a charged 2-cell or
3-cell Li-Po battery pack, or a 4-9 cell (1.2VDC/cell) NiMH. Connect the RED
to battery pack POSITIVE (+) & the BLACK to battery pack NEGATIVE (-).
Note: The Mongoose Crawler is default programmed with Li-Po Cut-Off Circuitry turned ON in all
Throttle Profiles. See Custom Programming Sheet to change this setting.
CHECK FOR PROPER GEARING
Proper brushless motor gearing is determined by motor & ESC
temperatures during and at the end of the run.
Refer to the ‘PROPER GEAR SELECTION’ portion of the CUSTOM PROGRAMMING
Sheet (Pg.5) to determine proper gearing & avoid overheating.
1. DISCONNECT BRUSHLESS MOTOR SENSOR HARNESS
The Mongoose Crawler automatically switches to Brush-Mode when the
ESC power is switched ON and no brushless sensor harness is connected.
2. MOTOR CAPACITORS
Electric brush-type motors generate RF noise that causes interference. Three
0.1µF (50V) non-polarized, ceramic capacitors must be used on all motors
to reduce motor noise & prevent ESC damage.
Note: Some motors come with factory-installed capacitors. If your motor only has 2
capacitors, you need to install a capacitor between the positive & negative motor tabs.
Solder 0.1µF (50V) capacitors between:
• POSITIVE (+) & NEGATIVE (–) motor tabs.
• POSITIVE (+) motor tab & GROUND tab*.
• NEGATIVE (–) motor tab & GROUND tab*.
Negative (–) motor tab
0.1µF Capacitors
Positive (+) motor tab

DO NOT USE SCHOTTKY DIODES
3. CONNECT ESC’S BLUE & YELLOW WIRES TO MOTOR
With brush-type motors, the ESC’s BLUE power wire goes to the NEGATIVE (–)
Motor Tab & the YELLOW power wire goes to the POSITIVE (+) Motor Tab.
a . Connect the BLUE ESC power wire to the NEGATIVE (–) Motor Tab.
b . Connect the YELLOW ESC power wire to the POSITIVE (+) Motor Tab.
Additional Novak 2mm low-loss power connectors available from www.teamnovak.com
4. CONNECT SPEED CONTROL TO BATTERY PACK
Connect speed control’s BLACK and RED power wires to a charged 2-cell or
3-cell Li-Po battery pack, or a 4-9 cell (1.2VDC/cell) NiMH. Connect the RED
to battery pack POSITIVE (+) & the BLACK to battery pack NEGATIVE (-).
Note: The Mongoose Crawler ESC is default programmed with Li-Po Cut-Off Circuitry turned ON in
all Throttle Profiles. See Custom Programming Sheet to change this setting.

step 2–ESC MOUNTiNG
Mount the speed control so that the power wires are as far from other
electronics as possible. Make sure that the speed control or the power
wires will not interfere with any moving parts in the vehicle. Select a
location that has good cooling and allows airflow through heat sinks.
If the ESC gets air flow, it will run cooler; and that means it will be more efficient!
1. MOUNT SPEED CONTROL IN VEHICLE
Use the included double-sided tape (do not use glue) to mount the
speed control in the place where the stock ESC was located (For
Losi®Mini-Rock Crawler™, unscrew one side of the twin vertical plate
chassis and place Mongoose Crawler toward the rear of radio plate,
under the receiver). Avoid contact with side walls or other chassis
components to avoid vibration damage.
Be sure receiver & antenna are mounted as far from ESC, power wires, battery &
servo as possible--these components all emit RF noise when throttle is applied.
On graphite or aluminum chassis vehicles, it may help to place receiver on
edge with crystal & antenna as far above chassis as possible.
Note: Mount antenna as close to receiver as possible--trail any excess wire off top
of antenna mast (cutting or coiling excess antenna wire will reduce radio range).
2. SECURE POWER CAPACITOR TO CHASSIS
Use included double-sided tape, or a tie-wrap, to mount Power
Capacitor to the vehicle’s chassis or connect to power wire. Capacitor
can also be tie-wrapped along the power wires--this requires less space
on the chassis and provides good isolation from vibration.
3. INSTALL ON/OFF SWITCH
Use a screw or a piece of the included double-sided tape, and
mount the switch where it will be easy to access--be sure to select
a position where it will not get damaged or get switched OFF in a
crash or during a roll-over.

step 4– one-touch programming
transmitter adjustments
If you have any problems with Step 4, adjust transmitter as follows
and then repeat the One-Touch programming in Step 4:
A. Set HIGH ATV or EPA to maximum setting.
[amount of throw at full throttle]
B. Set LOW ATV, EPA or ATL to maximum setting.
[amount of throw at full brakes]
C. Set EXPONENTIAL to zero setting. [throttle channel linearity]
D. Set THROTTLE CHANNEL REV. SWITCH to either position.
E. Set THROTTLE CHANNEL TRIM to middle setting.
[adjusts neutral position/increases or decreases coast brakes]
F. Set ELECTRONIC TRIGGER THROW ADJUSTMENT to 50%
throttle and 50% brake throw--best for reversible ESCs.
[adjusts trigger throw electronic/digital pistol-grip transmitters]
G. Set MECHANICAL TRIGGER THROW ADJUSTMENT to
position with 1/2 throttle and 1/2 brake throw.
With ESC connected to (at least) a receiver & a charged battery pack:
1. TURN ON THE TRANSMITTER’S POWER
2. PRESS & HOLD ESC’S ONE-TOUCH/SET BUTTON
3. TURN ON THE SPEED CONTROL’S POWER
With transmitter throttle at neutral, and still pressing the SET button,
slide the ESC’s ON/OFF switch to ON position.
4. CONTINUE HOLDING SET BUTTON UNTIL RED LED COMES ON
5. RELEASE SET BUTTON AS SOON AS LED TURNS RED
6. PULL TRANSMITTER THROTTLE TO FULL-ON POSITION
Hold it there until the green status LED turns solid green.
Note: Motor will not run during programming even if connected.
7. PUSH TRANSMITTER THROTTLE TO FULL-BRAKE/REVERSE
Hold it there until the green status LED blinks green.
8. RETURN TRANSMITTER THROTTLE TO NEUTRAL
Red status LED will turn solid red, indicating that speed control is
at neutral and that proper programming has been completed.
NOTE: If transmitter settings are changed, One-Touch Programming must be
repeated. If you experience any problems, turn off ESC & repeat One-Touch.
REMEMBER: Whenever the One-Touch set-up is performed, the speed
control will automatically revert back to the factory default settings & the
Throttle Profile will revert to #1 when in Brushless-Mode.

If you are going to use different power wire connectors, we suggest low-
loss, high power connectors like Dean’s Ultra or Novak’s connectors (Novak
#5721). To prevent possible cross-connection of motor phase wires, we do
not recommend the use of connectors on motor power wires of sensor-based
brushless motors.
• Use polarized connectors. Reverse voltage will damage ESC & void warranty.
• Use a female connector on battery packs to avoid shorting.
When wiring the vehicle’s electronics, shorter length wires & clean/neat
installations will give you better performance, higher efficiency, & less radio
problems (glitching, poor range, etc.). Try your best to keep all power wires
away from signal wires, the receiver, and the antenna.
