WIRING MOTOR TO ESC
• Solder power wires at motor by stripping 1/8-1/4" of
insulation from the end of the motor power wire (14G).
Tightly twist strands of wire, lightly tin, and insert into proper
solder tab's hole (tabs are identified by lettering that is
engraved in the end cap of the motor--see photo below). Use
soldering iron to apply heat to exposed wire that is extending
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 the solder tab (about 1/16" above
PCB)--
make sure no strands of wire 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.

• Note: Power wires can also be soldered flat onto the PCB solder tabs.
Strip 3/16-1/4" of insulation from the end of the new wire.
Tightly twist strands of wire, and tin with solder. Lay the
stripped & tinned end of the wire flat on the PCB solder tab
and use soldering iron to heat the end of the wire, and add
solder to form a clean solder joint between the wire and the tab.
IMPORTANT NOTE: DO NOT OVERHEAT SOLDER TABS
Prolonged/excessive heating of solder tabs will damage PCB.
PRECAUTIONS
• WATER & ELECTRONICS DON'T MIX Never allow water, moisture,
or other foreign materials to get inside motor, or on PCBs.
• CHECK MOTOR SCREWS Remember to check all motor
screws for loosening. The 3 main 4-40 socket head screws on
the shaft end of the motor may become loose after a few
runs of the motor, and will need to be tightened.
• NOVAK MOTORS WITH NOVAK ESCs ONLY The SS series
of motors have been specially designed for use with sensor-
based Novak Brushless ESCs Only! Use any Novak sensored
motor with any Novak brushless ESC as long as the ESC has a
higher wattage rating than the motor.
• INSULATE WIRES Always insulate exposed wiring with heat
shrink tubing to prevent short circuits.
• NO SOLVENTS Exposing the motor to any type of solvents
can damage the exposed material.
SENSOR-BASED DESIGN BENEFITS
• Constant Rotor Position Knowledge Always knowing what
angle the rotor is at, allows instantaneous response and
smooth transitions from neutral to drive.
• Smooth & Controlled Low Speed Driveability Rotor position
is key to smooth acceleration without delivering abrupt and
uncontrolled bursts of power.
• Strong/Consistent Brakes & Starting Torque Rotor position
knowledge results in consistent starts & stops, without hesitation
or inconsistent lag times before acceleration or braking.
• Locked Rotor & Thermal Protection Position & temperature
sensors inside motor provide unparalleled thermal protection
for your investment, letting you to run pack after pack without
worrying about overheating the motor, ESC, or magnets.
HOOK-UP INSTRUCTIONS
1. MOTOR CAPACITORS & SCHOTTKY NOT NEEDED
Novak brushless motors have built-in motor capacitors, and
like all reversible ESCs, does not use an external Schottky
diode--Schottky diodes damage reversible ESCs.
2. CHECK MOTOR SCREW LENGTH
Insert the M3 motor mounting screws that came with your
vehicle through the motor mounting plate in vehicle. You
need to have no more than 1/8" of screw extending past
the vehicle's mounting plate (2-4mm). Too little can strip
the threads in the end bell, and any more will cause short-
circuiting/damage inside the motor & will void warranty.
3. INSTALL PINION GEAR (see GEAR SELECTION on back)
Install pinion gear on motor and position set-screw over flat
on end of shaft. Test fit motor in vehicle to align pinion and
spur gears, then tighten pinion gear on shaft.
4. INSTALL MOTOR IN VEHICLE
• Determine the best routing for sensor harness & motor
power wire. Some off-road cars may require unsoldering
motor to route wires through the shock tower--refer to the
"WIRING MOTOR TO ESC" section.
• Using the M3 motor screws that came with your vehicle,
attach motor to vehicle's motor mount using one of the
three sets of threaded mounting holes--select a mounting
position that will avoid short-circuiting of solder tabs on conductive
surfaces such as aluminum or graphite.
• Check gear mesh for proper amount of play. You want to
have a small amount of free play between the pinion and
spur gears (about the thickness of piece of paper)--check
free play at several positions around the spur gear.
• Avoid using excessive force when tightening motor screws,
as the threaded holes could become stripped.
GEAR SELECTION (Important)
SS5800 Motor
With the SS5800 motor start with 2 teeth lower pinion gear
than you would use with a 27 turn "stock" brush-type motor.
SS4300 Motor
With the SS4300 motor start with 3 teeth lower pinion gear
than you would use with a 27 turn "stock" brush-type motor.
Because of the broader power band of the brushless motor, you
can go with a 1 to 3 tooth higher pinion than the above rec-
ommendations for more top speed, but remember that going
with 3 or more teeth higher will produce excessive speed con-
trol heating. Be sure to check the operating temperature of
the ESC after making any gearing adjustments--the Super Sport
ESC is designed to operate comfortably between 160ºF and 180ºF
(this is warmer than typical brush-type ESC temperatures).
If you had a low turn modified brush-type motor in your vehicle before
switching to the Super Sport system, and you do not change the gearing,
you will be under-geared and the vehicle will be slow at top speed!
You will want the final drive ratio in the vehicle to be:
7.30 : 1 for Touring Cars
9.00 : 1 for Off-Road Buggies
12.30 : 1 for Off-Road Stadium Trucks
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.

Note: Due to lower Kv rating, the SS4300 will not reach RPM limit in Profiles 5&6.
MOTOR MAINTENANCE
• CHECK MOTOR SCREWS Check all motor screws for
loosening at regular intervals, just like other hardware on your
vehicle. Note: The 3 main 4-40 socket head screws on the
shaft end of the motor may become loose after a few runs of
the motor and will need to be tightened. Also check the 3 flat
head screws securing the end cap on the back of the motor.
• CHECK MOTOR BEARING WEAR After extensive use, the
ball bearings in the end bells of your brushless motor may
need to be replaced. While the design of the motor will keep
the majority of the debris out of the bearings, some debris may
get in, and eventually wear will occur. If the shaft will not spin
freely, you may need to replace the motor bearings (replacement
bearing sets are available in Novak accessory kit #5905 and include
bearing replacement instructions--If you do not feel comfortable
changing the bearing on your own, please contact our Customer
Service Dept. for assistance). A small drop of light oil on the
bearings periodically can help extend bearing life--too much oil
will cause problems, so apply sparingly.
ACCESSORIES
BATTERY/MOTOR 14G POWER WIRE
Replacement silicone power wires for your brushless motor system
are available in Novak kits #5500 (36"red/36"black), #5505 (36"
red/36"blue), or #5508 (2 each of 9"red/black/blue/yellow/orange).
REPLACEMENT BEARINGS & FRONT END BELL SET
After extensive use, the ball bearings in the end bells of your
brushless motor may need to be replaced. Replacement motor
bearings & front end bell are available in Novak kit #5905.
SENSOR HARNESS WIRING
Should any of the 26G Teflon wires pull out of the connector
on the end of the motor's sensor harness, replace them into
the appropriate slot in the connector as shown below. The
connector has small plastic tabs that grab a small raised barb
on the back of the metal socket that is crimped onto the ends
of the Teflon wire. The plastic tab should be checked to make
sure it has not deformed excessively before inserting the socket
into the plastic connector housing.
