Novak Havoc Pro SC Track Guide (55-1745-1 Rev.3) - Manual (Page 2)

The Havoc Pro SC has a user-
replaceable input harness
with a 2mm mini plug on
the ESC end of it and the
industry-standard connector
on the receiver end of it.
The Havoc Pro SC works with
all major radio brand’s new
receivers [Refer to Figure 1
to see how to connect the
included user-replaceable input
harness]. However, some very
old receivers must have the
wiring sequence in the plastic
3-pin JST connector housing
changed on the receiver end.
NOTE: The receiver & servo electronics may be damaged
if the sequence is incorrect.
For instructions on changing the wiring sequence for older receivers, visit the
Novak Web site (www.teamnovak.com).

step 1–connect input harness step 3–Wire ESC to Motor
step 2–mount esc
Mount the speed control so that the power wires are as far away 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 speed control 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 to mount the speed control in vehicle
(do not use glue). 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 TRANS-CAP MODULE TO CHASSIS
Use included double-sided tape, or a tie-wrap, to mount Power Trans-
Cap Module to the vehicle’s chassis or shock tower. Module 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 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 during a crash or roll-over.
4. SECURE POWER WIRES
To avoid vibration damage, tie wrap the power wires together or to a
point on the vehicle.
The Havoc Pro SC ESC is compatible with all Novak 540 and 550-sized brushless
sensored motors. It is not compatible with brushed or sensorless brushless motors.
1. INSTALL PINION GEAR
Install pinion on motor and align pinion and spur gears. Tighten pinion’s set screw
on the flat of motor shaft.
2. ADJUST MOTOR FOR PROPER GEAR MESH
A. Adjust the motor position for proper amount of free play. You NEED a small amount
of play between the pinion gear and the spur gear (about the thickness of a 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.
B. Tighten motor mounting screws–Avoid using excessive force that could break screws
or strip the threaded holes in motor.
3. CHECK FOR PROPER GEARING
The brushless motor (with sintered rotor) & ESC should NOT be hotter than 160°F
after a 5 minute run. Lower the gearing until both the ESC & motor are under this
temperature. The cooler the ESC runs, the better the performance of the system.
4. SOLDER MOTOR POWER PHASE WIRES TO MOTOR
A. Cut the ESC’s BLUE, YELLOW & ORANGE silicone motor power wires to the desired
length, and strip 1/8-1/4” of insulation from the end of each wire. Tightly twist
the exposed strands of wire and tin with solder.
B. Place the ESC’s BLUE Phase ‘A’ motor wire onto motor’s ‘A’ solder tab & solder.
Use a soldering iron to apply heat to exposed wire; begin adding solder to tip of
soldering iron & to wire. Add just enough solder to form a clean & continuous
joint from the plated area of the solder tab up onto the wire. Trim any excess
wire with side cutters.
C. Solder the ESC’s YELLOW Phase ‘B’ motor wire to the motor’s ‘B’ solder tab as
described in Step 3B above.
D. Solder the ESC’s ORANGE Phase ‘C’ motor wire to the motor’s ‘C’ solder tab as
described in Step 3B above.
IMPORTANT NOTE: DO NOT OVERHEAT SOLDER TABS
Prolonged/excessive heating of solder tabs (motor or ESC) will damage PCB.
Note: Make sure no wire strands have strayed to an adjacent solder tab, this will
result in short-circuiting & severe ESC damage, which will void the warranty.
5. CONNECT MOTOR SENSOR HARNESS TO ESC
Insert the 6-pin connector on the end of the motor’s sensor wires into ESC’s sensor
harness socket—the connector is keyed and will only insert in one direction. To
connect to the ESC, Novak suggests its Brushless Shielded Sensor Harnesses, which
are available in three lengths: 4”/100mm (Novak #5351), 6”/150mm (Novak
#5352) & 9”/230mm (Novak #5353).
FACTORY-INSTALLED POWER TRANS-CAP MODULE REQUIRED
The factory-installed Power Trans-Cap Module MUST be used with brushless motors.
If Power Trans-Cap Module becomes dented or damaged, ESC failure can occur--
replace immediately (Novak Kit #5679). Longer wires will decrease performance.
DO NOT USE SCHOTTKY DIODES
Schottky diodes must NOT be used with reversible ESCs.
Schottky diode usage will damage the ESC & void warranty.
MOTOR CAPACITORS NOT NEEDED
Novak brushless motors do not require external motor capacitors.
To connect the Havoc Pro SC to the main battery pack using connectors, we suggest
low-loss high power connectors like Dean’s Ultra Plug.
• Use polarized connectors. Reverse voltage will damage ESC & void warranty.
• Use a female connector on battery packs to avoid shorting.
1. INSTALL BATTERY CONNECTOR
A. Cut the RED & BLACK silicone battery power wire to the desired length, and strip
1/8”–3/16” of insulation from the end of each wire. Tightly twist and tin the ends
of the exposed wire with solder.
B. Solder the ESC’s RED (+) battery wire to the connector’s POSITIVE (+) contact.
C. Solder the ESC’s
BLACK (–) battery wire to the connector’s NEGATIVE (–) contact.
D. Cover the exposed solder joints with heat shrink tubing to prevent possible short circuits.
2. CONNECT ESC TO BATTERY PACK
Connect the speed control’s battery connector to a fully charged 2S LiPo,
2S LiFe cells, or 4-6 NiMH cells (1.2 VDC/cell) battery pack.
NOTE: If using NiMH or LiFe batteries, the Voltage Cut-Off Circuitry must be
programmed for the appropriate battery type (refer to Havoc Pro SC Track Guide).

With the higher performance of brushless systems, undesirable radio system
noise may occur when used with lower quality radio systems. 2.4GHz radio
systems are the best to use. FM radio systems are acceptable, as long as
the system is high quality. AM radio systems are not recommended.
