STEP 4
HOOK-UP INSTRUCTIONS (Refer to set-up photo)
1. INSTALL MOTOR CAPACITORS
Electric motors generate radio noise that can interfere
with your receiver and cause radio problems. Included
in the accessory kit with the speed control are three
0.1
µ F (50V) non-polarized, ceramic capacitors. These
capacitors must be installed on every motor to help
reduce the noise generated by the motor and also to
prevent possible damage to the speed control.
Solder 0.1
µ F (50V) capacitors between:
• POSITIVE (+) motor tab & NEGATIVE (-) motor tab.
• POSITIVE (+) motor tab & GROUND tab*.
• NEGATIVE (-) motor tab & GROUND tab*.
*If your motor does not have a ground tab, solder the capacitor
leads to the can of the motor as shown below.
Negative (-) motor tab
0.1 µ F Capacitors
Schottky diode
Positive (+) motor tab
Ground / motor can
2. CONNECT SPEED CONTROL TO THE RECEIVER
After the proper input plug plastic has been installed to
match the receiver (Refer to Step 1), plug the speed
control into the THROTTLE CHANNEL of the receiver.
3. CONNECT SPEED CONTROL TO THE BATTERY PACK
Plug the white JST connector from the speed control
into the JST/Tamiya style connector on a fully charged
6 or 7 cell battery pack (1.2 volts DC/cell). The black
wire is negative (-) and the red wire is positive (+).
4. CONNECT SPEED CONTROL TO THE MOTOR
Plug the bullet connector on the red wire (+) of the
speed control to motor positive. Plug the other bullet
connector, on the blue wire (-), to motor negative.
A wiring kit with bullet connectors and a JST/Tamiya
connector is available in Novak kit #5810.
5. OPTIONAL USE OF SCHOTTKY DIODE
The Fusion ESC does not require an external Schottky
diode. However, using one will increase the efficiency
and reduce the operating temperature of the ESC.
Solder the lead CLOSEST to the silver stripe on the body
of the Schottky diode to the POSITIVE (+) motor tab.
Solder the lead OPPOSITE the silver stripe on the body
of the Schottky to the NEGATIVE (-) motor tab.
Schottky diodes are available in Novak kit #5640.
If installed backwards, a Schottky diode will be destroyed. The body
of a bad diode will normally crack open. Replace only with Schottky
diodes that have a minimum rating of 35 volts / 8 amps.
Proper transmitter adjustment is important for optimum
performance from your speed control. The basic throttle
channel adjustments for the transmitter are as follows:
1. Set HIGH ATV or EPA to maximum setting.
[Controls amount of throw from neutral to full throttle]
2. Set LOW ATV, EPA, or ATL to maximum setting.
[Controls amount of throw from neutral to full brakes]
[Reduce this after ESC adjustment to reduce amount of brakes]
3. Set EXPONENTIAL to zero setting.
[Controls the linearity of the throttle channel]
4. Set THROTTLE CHANNEL TRIM to middle setting.
[Adjusts the neutral position of speed control]
[Increase or decrease after ESC adjustment to adjust coast
brakes––can be used to give braking in neutral trigger position]
5. Set THROTTLE CHANNEL REVERSING SWITCH to
either position.
[Do not change switch position after programming]
6. Set ELECTRONIC TRIGGER THROW ADJUSTMENT to
70% throttle and 30% brake throw (or 7:3).
[Adjusts pistol-grip transmitter’s throttle trigger throw]
7. Set MECHANICAL TRIGGER THROW ADJUSTMENT
to position with 2/3 throttle and 1/3 brake throw.
[Adjusts pistol-grip transmitter’s throttle trigger throw]
STEP 5
TRANSMITTER ADJUSTMENT
STEP 6
SPEED CONTROL ADJUSTMENT
Before beginning this step, the speed control should be
connected to the receiver and to a charged 6 or 7 cell
battery pack, and the transmitter should be adjusted.
Adjustment of your Fusion speed control is required for
proper operation. When the status LED is red, the speed
control is in the neutral position (no throttle or brake).
When the status LED is green, the speed control is either at
the full throttle or full brake position.
1. CONNECT THE BATTERY
Plug the speed control into a fully charged 6 or 7 cell
nickel-cadmium battery pack.
2. TURN ON TRANSMITTER THEN THE SPEED CONTROL
3. PRESS AND HOLD ESC’S ONE-TOUCH BUTTON
With transmitter throttle at neutral, press and hold the
ESC SET button until the status LED turns solid red.
4. RELEASE ESC SET BUTTON WHEN LED IS RED
5. PULL THROTTLE TO FULL-FORWARD POSITION
Hold it there until the status LED turns solid green.
NOTE: The motor will not run during programming even if it
is connected to the speed control.
6. PUSH THROTTLE TO FULL-BRAKE POSITION
Hold it there until the status LED blinks green.
7. RETURN TRANSMITTER THROTTLE TO NEUTRAL
Status LED will turn solid red, indicating that throttle is
at neutral and proper programming has been completed.
8. CHECK OPERATION OF THE SPEED CONTROL
Connect the motor and check for proper operation.
With no throttle or brake applied, the status LED should
be solid red and the motor should not be running. At
full throttle position, the status LED should be solid
green and the motor running full speed. At full-brake
position, the status LED should be green and the motor
should not be running.
9. SET THE COAST BRAKE AT TRANSMITTER (optional)
Adjust the THROTTLE CHANNEL TRIM on the transmitter
to get more or less coast brake. This is accomplished by
slightly shifting the neutral position. After adjustment be
sure that the status LED is still green at full throttle.
Speed control is programmed & ready to run !
If transmitter settings are changed at any time after the speed
control has been set-up, it will be necessary to complete the
programming sequence once again.
If you experience any problems during programming, turn off
the speed control and repeat the programming process.
BRAKE LIGHTS
The Fusion is equipped with built-in brake light circuitry to
power two LEDs.
(Novak Brake Light accessory kit #5655)
To connect brake lights to the Fusion:
1. Strip about 1/8" of insulation off of both the red and the
black small (26 gauge) wires that exit the back of the
speed control along with the battery and motor wires.
2. Strip about 1/8" of insulation off both ends of the small
(26 gauge) extension wires that are the correct length to
reach the position that the brake light is mounted.
3. Solder extension wires onto the brake light wires from
the speed control. If two LEDs are to be used, then solder
two extension wires to each brake light wire from the
speed control. Insulate solder joints with heat shrink tubing.
4. Solder end of the extension wire from the red brake light
wire to the lead on the notched/flat side of the LED. Solder
end of the extension wire from the black brake light wire
to other LED lead. Insulate solder joints with heat shrink.
Note: Some LEDs have the flat on the negative side. If LED does not
illuminate, reverse the red and black brake light wires.

FUSION SET-UP
Extra 0.1 µ F capacitors
available in Novak kit #5620.
The Fusion is equipped with dual-profile throttle circuitry
that allows you to choose the right drive frequency for the
type of motor that you are using. Modified or Stock
To check or change the active throttle profile:
1. TURN ON TRANSMITTER THEN THE SPEED CONTROL
2. PRESS AND HOLD THE ESC'S ONE-TOUCH BUTTON
Continue to hold button until the status LED turns solid
green. The LED will first turn solid red, and then it will
turn solid green.
3. RELEASE THE ONE-TOUCH BUTTON
After releasing, status LED will blink red. The speed that
the LED blinks indicates the active profile.
Quick = MODIFIED Slow = STOCK
4. While the status LED is blinking, PRESS AND RELEASE
THE ONE-TOUCH BUTTON. This will select the next
profile and the LED will blink the appropriate speed to
indicate which profile is selected.
5. Once the desired throttle profile is selected and the
One-Touch button has not been pressed for approximately
five seconds, the speed control loads the selected
profile into memory, exits the profile selection mode,
and the status LED turns solid red (neutral position). At
this point the selected throttle profile has been stored in
the speed control's non-volatile memory (it will remain
the active profile even after speed control is shut off).
The speed control is ready to run.
