T
he ultimate high-voltage/high-power brushless is here & it is the HV-Maxx!
The HV-Maxx brushless motor system is the best high-power reversible electronic speed control & sensor-based brushless
motor upgrade that you can throw at your big trucks, hot boats, or any other high-power R/C application where you want all
the benefits of brushless motors & it’s even smoother, more controlled, and more driveable than standard brush-type systems!
With 3 factory throttle programs to choose from & Novak’s Smart Braking II (you don’t go into reverse until you shift into reverse by returning the trigger to
neutral and then back to reverse), the HV-Maxx is perfect for any high-power application. The HV-Maxx system has
Thermal Overload Protection
in both the
motor & ESC,
high-power B.E.C.
for strong/fast servo response,
Polar Drive & Digital Anti-Glitch circuitries
for cool & smooth operation, and
Radio Priority
circuitry
for the ultimate in control, right down to the end of the battery. Add to this the included Power-Boost ESC Cooling Fan kit & factory-installed
motor heat sink, the user-replaceable battery wires, power capacitor, ON/OFF switch, & input harness, and the HV-Maxx is ready for anything!
To benefit from all of the HV-Maxx’s extensive technical features, PLEASE READ ALL INSTRUCTIONS
POWER-BOOST ESC COOLING FAN KIT
[Novak kit #5646]
Direct-replacement for the cooling fan kit that is included in the HV-Maxx high-voltage
brushless system. Everything needed to pull maximum power from the HV-Maxx
ESC for hot set-ups: custom-fit fan bracket, mounting screws, & high-volume
cooling fan that plugs into HV-Maxx ESC’s fan power output jack.
SUPER-FLEX SILICONE POWER WIRE
[Novak kits #5500 & 5530]
Novak Super-Flex wire for power wiring. 14 guage silicone wire in kit #5500
(36”red & 36”black), and 12G silicone in kit #5530 (36”red & 36”black).
INPUT SIGNAL HARNESS

ready to solder to the HV-Maxx ESC’s Direct-Solder Wire Tabs.
H-SERIES MOTOR END BELL & BEARING SET
After extensive use, the ball bearings in the end bells of your brushless mo-
tor may need to be replaced. Replacement front end bell with oversize bearing
installed & rear bearing are available in Novak kit #5910.
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!
CHECK MOTOR SCREWS
!
Check M3 motor mounting screw length––
too long of mounting screws
will damage motor & void warranty.
The main 4-40 socket head & end
cap’s flat head screws may also loosen after a few runs––tighten if needed.
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.
6 TO 14 CELLS ONLY
Never use fewer than 6 or more than 14 cells (7.2-16.8VDC, 1.2VDC/
cell) in the vehicle’s main battery pack(s).
NOVAK MOTORS ONLY
The HV-Maxx ESC is specially designed for use with sensor-based
Novak HV-Series Brushless Motors Only! You may replace motor with
Novak sensored motor rated up to 375W (ESC’s rating)––Novak SS-Series
(540 size) motors will work, but will run hot and thermally shutdown.
At the time of printing, there are no other motor’s available that work with
the HV-Maxx ESC––check our website for further updates & compatibilities.
NO REVERSE VOLTAGE
!
Reverse battery polarity can damage ESC & void warranty. Disconnect
battery immediately if a reverse connection occurs.
ALWAYS USE ESC HEAT SINKS
Heat sinks are factory-installed on your HV-Maxx ESC and MUST be
used for maximum cooling and performance––
Never allow separate
heat sinks to touch each other or any exposed metal or conductive
surface, as this will cause a short circuit & damage ESC.
POWER CAPACITOR REQUIRED
An external power capacitor is installed and
MUST
be used with your
HV-Maxx ESC.
Failure to use Power Capacitor will result in higher ESC
operating temperatures & possible thermal shut-down.
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.
INSULATE WIRES
Always insulate exposed wiring with heat shrink tubing 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.
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-BRAKES
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 throttle is at neutral,
and proper programming has been completed.
Your HV-Maxx Brushless System is now Ready-To-Run
!
NOTE: If transmitter settings are changed, programming must be repeated. If
you experience any problems, turn off ESC and repeat programming.
