Novak HV Pro ESC (with purple heat sinks) Programming and Gearing (55-3410-1) - Manual

P1 P4
• WATER & ELECTRONICS DON’T MIX Never allow water, moisture, or
other foreign materials to get inside motor, or on PC boards.
• CHECK MOTOR SCREWS Check all motor screws for loosening.
The 3 main 4-40 socket screws on the shaft end of motor may
become loose after a few runs of motor & will need to be tightened.
• NOVAK MOTORS WITH NOVAK ESCs ONLY The HV series of
motors have been specially designed for use with the sensor-based
HV-Maxx Brushless ESC Only! Use Novak sensor-based motors with
Novak brushless ESCs with higher wattage rating than the motor.
• ALWAYS INSULATE EXPOSED WIRING to prevent short circuits.
• NO SOLVENTS Exposing the motor to any type of solvents can
damage the exposed material.

GEAR SELECTION (Important)
HV4400 Motor @ 12 cells (14.4VDC)
With the HV4400 motor start with 2 teeth lower pinion gear
than the “stock” gearing for most 1/10th scale monster trucks
like the Traxxas E-Maxx & Kyosho Twin Force.
Because of the broader power band of brushless motors, you can
go with 1-3 tooth higher pinions than the above recommendation
for more top speed, but remember that going with 3 or more
teeth higher will produce excessive ESC & motor heating. Be sure
to check the ESC operating temperature after making any gearing
adjustments--the HV-Maxx ESC is designed to operate comfortably
between 160ºF and 180ºF (warmer than typical brush-type ESC).
You will want the final drive ratio in the vehicle to be:
22 : 1 for Monster Trucks @ 12 cells
9 : 1 for Off-Road Buggies @ 6-7 cells
12.3 : 1 for Off-Road Stadium Trucks @ 6-7 cells
Higher final drive ratios give longer run time at the expense of top speed. Lower
ratios result in higher ESC temperatures--too low may result in thermal shut-down.

MOTOR & ESC WIRING
REPLACEMENT POWER CAPACITOR INSTALLATION
• Insulate capacitor leads with heat shrink tubing.
• Solder capacitor’s NEGATIVE(–) lead {shorter lead on
capacitor} to the HV-Maxx’s BLACK PowerCap wire that
comes from the smaller hole on ESC’s BAT.2(-) tab.
• Solder capacitor’s POSITIVE(+) lead to RED PowerCap wire
coming from smaller hole on ESC’s BAT.1(+) tab.
HARD WIRING ESC TO BATTERY PACK
• DOUBLE CHECK polarity & battery number of each
connection before soldering to packs--INCORRECT WIRING
WILL DAMAGE ESC (check tab I.D. on ESC labels).
{ Put a tie-wrap or tape around each set of battery wires }
coming from ESC to avoid possible incorrect wiring.
• Cut ESC’s BLACK BAT.1(-) power wire to the desired length
& strip 1/8-1/4” of insulation off the end. Solder to
NEGATIVE(–) of battery #1 (6-7 cell pack). Repeat for BLACK
BAT.2(-) power wire going to NEGATIVE(–) of battery #2.
• Cut RED BAT.1(+) power wire to length & strip 1/8-1/4” of
insulation off end. Solder to battery #1 POSITIVE(+). Repeat
for RED BAT.2(+) wire going to battery #2 POSITIVE(+).
REPLACING POWER WIRES AT ESC & MOTOR
The HV-Maxx ESC comes factory wired to the brushless motor
& batter y connectors. For custom installation or for
replacement of the Silicone power wires:
• Remove power wires from PCB solder tabs (remove ESC
from model to get access to bottom side of solder tabs). Use a
soldering iron to apply heat to the power wire’s solder joint
on bottom side of solder tab, while gently pulling up on
the wire to remove it from the hole in the PCB.
• Replace power wires by stripping 1/8-1/4” of insulation
from end of the new wire. Tightly twist strands of wire &
insert into proper solder tab’s hole (tabs are identified on the
ESC case labels & on the end cap of the motor--see below). Use
soldering iron to apply heat to exposed wire that extends
past bottom of PCB, and begin adding solder to tip of
soldering iron and to wire. Add just enough solder to form
a clean & continuous joint from the plated area of solder
tab up onto the wire. Use side cutters to trim remaining
(now soldered) wire from below solder tab (about 1/16”
above PCB)
--make sure no wire strands have strayed to an adjacent
solder tab as this can result in short-circuiting & damage to the
electronics, which will void the product’s warranty.
•Be sure to solder phase wires to appropriate tabs on Motor (A/B/C)•
A = BLUE
B = YELLOW
C = ORANGE
• Note: Power wires can also be soldered flat on the solder tabs.
Strip 3/16-1/4” of insulation off end of the new wire. Tightly
twist strands of wire & tin with solder. Lay end of wire flat
on solder tab & use soldering iron to heat the end of the wire.
Add solder to form a clean solder joint between wire & tab.
IMPORTANT NOTE: DO NOT OVERHEAT SOLDER TABS
Prolonged/excessive heating of solder tabs will damage PCB.
CHANGING BATTERY CONNECTORS
If you want to change Tamiya-style battery connectors on
the ESC, we recommend using high-quality/low-resistance
connectors, such as Dean’s Ultra Plug. Use female connectors
on battery packs to avoid shorting. Change one connector
at a time to avoid incorrect wiring
(check tab I.D. on ESC labels).
Always use a connector that can not be connected backwards!
