SENSOR-BASED DESIGN BENEFITS
• Rotor Position Knowledge--With ESC & motor continuously synchronized
via the motor harness, the sensor-based system provides instantaneous
throttle response & smooth neutral to drive transitions--NO COGGING.
• Smooth/Controlled Low Speed Driveability--Rotor position knowledge
is key to smooth acceleration--no abrupt/uncontrolled bursts of power.
• Strong/Consistent Brakes & Starting Torque--Rotor position
knowledge results in consistent starts & stops, no lag time or hesitation
before acceleration or braking--this translates to consistent lap times.
• Locked Rotor & Thermal Protection--Position & temperature sensors
inside the motor provide unparalleled protection when used with Novak
brushless ESCs, letting you to run pack after pack without worrying
about overheating the motor, ESC, or magnets when properly set-up.
PRECAUTIONS
NEVER FREE-REV THE MOTOR Free-running your brushless
motor in a no-load condition can result in rotor failure and ESC
transistor damage & will void the product's warranty!
Never free-rev your system to "see how it runs", or you may not get to drive it again!
• 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 after a few runs of the motor.
• NOVAK MOTORS & ESCs FOR BEST RESULTS Use Novak sensored
motors with Novak Brushless ESCs for best performance & protection. Only
use motors with the proper number of turns to match ESC's rating.
Use of this brushless motor with non-Novak ESCs that advance
motor timing can result in excessive current draw & severe motor
damage that will NOT be covered by the product's warranty!
• DO NOT use 3.5-7.5T motors with Havoc, XBR, Super Sport, or Mongoose ESCs.
• INSULATE EXPOSED WIRES Use heat shrink tubing to prevent shorts.
• NO SOLVENTS Do NOT expose the motor to any type of solvents.
• SET GEAR MESH PROPERLY Too tight of a gear mesh can result in
motor pinion shaft breakage--be sure to adjust mesh properly.

MOTOR MAINTENANCE
• CHECK ALL MOTOR SCREWS for loosening at regular intervals, just like
other hardware on your vehicle. Note: The 3 main socket head screws
that hold the motor together may require tightening after a few runs of
the motor. 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 motor's
closed design will keep most dirt & debris out, but some will get in
and eventually cause wear. If the shaft does not spin freely, you may
need bearing replacement (replacement bearing accessory kits are available
from Novak). A small drop of light oil on the bearings periodically can
help extend bearing life--however, too much oil will attract dirt and will
cause problems, so apply sparingly.
• CLEAN INSIDE MOTOR periodically by removing front end bell,
removing the rotor, and blowing out the inside of the motor with
compressed air. Be sure not to lose any small shim washers that may be
on the ends of the rotor shaft & keep them in the correct location.
SENSOR HARNESS WIRING
Should any of the 26G Teflon wires pull out of the motor's sensor
harness connector, re-insert them in the connector's appropriate
slot as shown below. There is a small plastic tab that grabs a small
raised barb on the back of the metal socket crimped onto the Teflon
wire's end. Check the plastic tab to make sure it has not deformed
excessively before inserting the socket into the plastic connector
housing with the barb toward the plastic tabs.

INSTALLATION INSTRUCTIONS
1. NO MOTOR CAPACITORS & SCHOTTKY NEEDED
Novak brushless motors do not need motor capacitors or external
Schottky diodes--Schottky diode usage will damage ESC.
2. CHECK MOTOR SCREW LENGTH & INSTALL MOTOR
• Insert the motor mounting screws that came with your vehicle
through the motor mounting plate. 540-size motors need no
more than 1/8" of screw extending past the vehicle's mounting
plate (2-4mm)--Too little can strip the motor's threads, too much
will cause internal motor damage & will void warranty.
• Attach motor to vehicle's motor mount using one of the sets of
threaded mounting holes--
select a mounting position that keeps the
solder tabs clear of conductive surfaces like aluminum or graphite.
3. INSTALL PINION GEAR (see GEAR SELECTION on back)
Install pinion on motor and test fit in vehicle to align pinion and
spur gears. Tighten pinion's set screw on the flat of motor shaft.
4. ADJUST MOTOR FOR PROPER GEAR MESH
• Adjust the motor position for proper amount of free play. You
NEED to have a small amount of play between the pinion gear
and the spur gear (about the thickness of piece of paper)--check
the free play at several positions around the spur gear to
ensure a proper mesh (just in case the gears are out of round).
MAKE SURE THE PINION/SPUR GEAR MESH IS NOT TOO TIGHT!
If gear mesh is too tight, motor shaft breakage can occur.
• Tighten motor mounting screws--Avoid using excessive force,
as the threaded holes in motor could become stripped.
5. SOLDER MOTOR POWER WIRES
• Determine the best routing in vehicle for the motor's silicone
power wires--avoid any moving parts & suspension.
• Prepare ends of power wires by stripping 1/8-1/4" of
insulation from end of wire. Tin wire ends with solder.
• Lay tinned end of the wire flat on the solder tab and solder
wires to proper tabs of the motor (refer to phase markings
below solder tabs). Apply heat with soldering iron to the power
wire and solder tab--begin adding solder to tip of iron and to
wire--Add just enough solder to form a clean & continuous joint
from the solder tab up onto the wire.
WARNING: Be sure no wire strands have strayed to an adjacent solder tab--this
will cause short-circuiting, damage electronics, & void product's warranty.
IMPORTANT NOTE: DO NOT OVERHEAT SOLDER TABS
Prolonged or excessive heating of the solder tabs will
cause damage & void the product's warranty.
6. CONNECT MOTOR SENSOR HARNESS
• Determine the best routing in vehicle for the motor's sensor
harness--securing sensor harness to the motor power wires with a
tie-wrap can provide a good location & also act as a strain relief.
• Connect one end of the harness to the ESC & the other end
to the motor's sensor harness connector located under the
back bearing cap. Be sure the plug on the end of the harness
inserts all the way into the sensor harness connector--the plug
& connector are keyed and will only go together one direction.

GEAR SELECTION ( Important )
Motor operating temperature is the ONLY
way to properly set the maximum vehicle gearing
The motor should be 160-175°F MAX at end of run!
Temperatures above 175°F will weaken the magnet & may
melt the coils! This voids warranty & can damage ESC!
Change the gearing to avoid overheating.

If you do not change gearing after switching to brushless, you will be over-
geared and will have slow acceleration & excessive temperatures!
Because of the broad power band of brushless, you can go 1-2 teeth higher pinion than the
above recommendations for more top speed, but remember any higher will produce excessive
ESC & motor heating. Check motor's operating temperature after making gearing adjustments.
See our website for additional gearing recommendations, final drive
ratios, or if your motor does not appear above.
MOTOR TIMING ADJUSTMENT
The Ballistic motor's timing is adjustable by simply loosening the three M2.5
flat head screws on the back bearing cap, rotating the bearing cap to desired
setting, and re-tighten the screws.
The motor's factory timing is marked with a 'N' on the timing label located
on the side of the back bearing cap and lines up with a groove milled into the
top of the back end bell. Novak motors are factory timed to the most efficient
setting for their given wind.
Advancing the timing will increase the motor's RPM range & reduce its torque,
but will also make it less efficient and it will pull more current, resulting in
higher ESC & motor operating temperatures.
Adjusting the timing beyond the '+' mark on the timing label will result in
dangerously high current draw and heating that can lead to ESC & motor
failure, and will void the product's warranty.
Retarding the timing will reduce the motor's RPM range & increase torque--
this usually also reduces current draw and lower operating temperatures. For
each timing mark (on label) reduced, increase pinion gear size by one tooth
to accommodate lower RPM range.
