Included with the Fusion ESC is the Novak Input Plug
System
TM
to convert the Futaba J style signal harness for
compatibility with Sanwa, KO, Kyosho, JR, Airtronics Z,
and Hitec radios.
Refer to Figures 1 through 3 to change plug.

CAUTION
Improper installation of these wires may cause damage
to the receiver, servo, and speed control.
The locking tab must not extend
outside the plastic plug housing.
STEP 2
HEAT SINK INSTALLATION
Two Micro Fin™ heat sinks have been included to provide
proper cooling for the Fusion ESC. The speed control will
operate cooler and run faster when the heat sinks are
installed.
DO NOT
use the Fusion without the heat sinks,
as this voids the warranty and may cause the speed control
to overheat and thermally shut down.
1. INSTALL THE LEFT HEAT SINK
Place the speed control on a flat surface and press one
heat sink
(longer fins go down onto transistor tabs)
onto the left bank of 3 transistor tabs.
NOTE: Do not use too much force when installing the
heat sinks because you can damage the transistors or other
components on the PC board. Never use a vise or pliers to
install the heat sinks.
2. INSTALL THE RIGHT HEAT SINK
Press the second heat sink (again, long fins down) onto
the right bank of 3 transistors tabs.
The heat sinks should press onto the transistor tabs with a
snug fit. If heat sinks are installed upside-down or shifted
off-center, they will be too loose and will not work properly.
3. DO NOT USE GLUE
Do not use glue or other types of adhesives to attach
the heat sinks to the transistor tabs.
4. DO NOT SHORT CIRCUIT HEAT SINKS
The two separate banks of transistor tabs or heat sinks
should never contact each other or other conductive
objects (metal, graphite, etc.), or they will short circuit
and damage the speed control.
STEP 3
MOUNTING INSTRUCTIONS
1. DETERMINE THE BEST ESC MOUNTING LOCATION
The speed control should be positioned away from
the receiver and antenna as shown in set-up photo on
back page. Choose a mounting position that will keep
power wires away from the receiver and antenna.
Choose a position that will provide maximum airflow
through the heat sinks to allow for proper cooling.
2. INSTALL THE SPEED CONTROL
Use the included double-sided tape to mount ESC.
3. INSTALL THE ON/OFF SWITCH
Determine a convenient place to mount switch where
it will be easy to get to. Mount switch using a piece of
double-sided tape. If your car has a switch mount
molded into the chassis, remove the two phillips head
screws from the switch housing and reassemble
switch into chassis using the 3/8" long screws that are
included in the speed controls accessory kit. Note the
direction of ON/OFF cover and reverse it if necessary.
4. INSTALL THE RECEIVER
Mount the receiver as far from the speed control,
motor, power wires, battery, and servo as possible.
These components all emit radio noise when the
throttle is being applied. If your car has a graphite or
aluminum chassis, place the receiver on its edge with
the crystal and antenna as far above the chassis as
possible. The receiver can also be mounted on the
shock tower.
5. INSTALL THE ANTENNA
Mount the antenna as close to the receiver as pos-
sible. Trail any excess wire off the top of the antenna
mast––Do not cut or coil excess wire.
Cutting or coiling excess wire will reduce radio range.

OPERATING INSTRUCTIONS
FUSION DUAL-PROFILE
The Fusion Dual-Profile high-frequency ESC (Electronic
Speed Control) features
Two User-Selectable Throttle
Profiles
and Novak's exclusive
One-Touch Set-Up™
. With
Polar Drive Technology™
and
Digital Anti-Glitch Circuitry
TM
,
the Fusion runs faster, longer, and smoother than other
sport level ESCs. While
Radio Priority Circuitry
TM
maintains
steering control even after the battery has discharged.
The Fusion also has built-in
brake light circuitry
to power
two external LEDs for added realism with Touring Sedans
and Formula One cars. (Two high-power brake LEDs and
versatile mounting hardware available in Novak kit #5655)
Novak's
Solid State RVP™
provides rugged protection
against reverse voltage application without the need for
fuses, while the built-in BEC (Battery Eliminator Circuit)
powers the radio system with no external receiver battery.
Other features include the
Novak Input Plug System™
for compatibility with all major radio systems,
Thermal
Overload Protection
, and purple anodized Micro Fin™
heat sinks for cooling. The factory installed JST/Tamiya style
battery connectors and bullet style motor connectors make
for quick and easy installation of the speed control into your
car or truck without the need to solder.

FUSION ACCESSORIES
BRAKE LIGHT KIT
The Fusion speed control comes equipped with built-in
circuitry to power two high-power brake light LEDs.
Novak's optional Brake Light Kit (#5655) comes com-
plete with two premium quality LEDs, versatile mounting
brackets to install brake lights behind the taillight section
of the car body or onto most any vertical or horizontal
surface on the chassis, and necessary wiring.
MOTOR CAPACITORS
To prevent radio interference problems, you must have
three 0.1
µ
F capacitors properly installed on every motor.
Included with the Fusion speed control are three 0.1
µ
F
(50V) capacitors for one motor. Additional 0.1
µ
F (50V)
capacitors are available in Novak kit #5620. Please refer
to Step 4 on the back page for proper motor capacitor
installation instructions.
HEAT SINKS
Replacement heat sinks are available for the Fusion ESC
in Novak kit #5408. These purple anodized Micro-Fin
heat sinks provide the cooling needed for the lower
operating temperatures and higher operating efficiencies,
and also help to prevent overheating.
PRECAUTIONS
• READ INSTRUCTIONS CAREFULLY BEFORE USING!
• WATER & ELECTRONICS DON'T MIX!
Do not operate
model in or around water. Never allow water, moisture,
or other foreign materials to get inside the ESC.
• 6 OR 7 CELLS ONLY
Never use more than 7 or fewer
than 6 cells (1.2 volt DC/cell) in the main battery pack.
• MOTOR CAPACITORS REQUIRED
Three 0.1
µ
F (50V)
ceramic capacitors must be properly installed on every
motor to prevent radio interference.
• DON'T LET TRANSISTOR TABS TOUCH
Never allow
the two transistor tab banks or the heat sinks to touch
each other or any exposed metal, as this will create a
short circuit and damage the speed control.
• DISCONNECT THE BATTERIES
Always disconnect the
battery pack from the speed control when not in use.
• TRANSMITTER ON FIRST
Always turn on the power of
your transmitter first so that you will have control of the
radio equipment when you turn on the speed control.
• DON'T GET BURNT!
Transistor tabs can get hot, so be
careful not to touch them until they cool.
• INSULATE WIRES
Always insulate exposed wiring with
heat shrink tubing to prevent short circuits.
RADIO INTERFERENCE
The high frequency switching operation of electronic
speed controls can generate radio interference. Here are
some common causes of radio interference problems:
• CAPACITORS NOT INSTALLED ON MOTOR
Electric
motors generate radio noise that can interfere with the
receiver. To prevent radio problems, every motor must
have three 0.1
µ
F (50V) ceramic capacitors installed on
it. Refer to Step 4 on back page for proper installation.
• RECEIVER/ANTENNA INCORRECTLY MOUNTED
The
receiver and antenna should be mounted as far from
the motor, power wires, battery, and servo as possible,
as these components all emit radio noise. On graphite
or aluminum, place receiver on edge with the crystal
and antenna as far above the chassis as possible. Mount
the antenna close to receiver and trail any excess wire
off the top of antenna. Do not cut or coil excess wire!
• MOTOR BRUSHES WORN
As motor brushes continue
to wear, excessive motor noise will be generated. To
avoid radio interference, worn motor brushes should
be replaced. The motor commutator may also need to
be cleaned or trued and can be machined to help the
motor run more efficiently.
