TRANSMITTER ADJUSTMENTS
STEP 2
MOUNTING INSTRUCTIONS
For proper speed control operation and programming
set the transmitter adjustments 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––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
50% throttle
and
50% brake/reverse
throw (or 5:5).
[Adjusts pistol-grip transmitter’s throttle trigger throw
on electronic/digital transmitters]
7.
Set
MECHANICAL TRIGGER THROW ADJUSTMENT
to
1/2 throttle
and
1/2 brake/reverse
throw.
[Adjusts pistol-grip transmitter’s throttle trigger throw
on mechanical/analog transmitters]
1. DETERMINE BEST ESC MOUNTING LOCATION
The ESC should be positioned away from receiver
and antenna as shown in the Set-Up photo on the
front. Choose a mounting position that will keep
the power wires clear from obstructing movement
of the suspension or the motor pod.
Remember, cooler operating temperatures mean higher
efficiency. So, choose a mounting position that allows
maximum airflow through the heat sinks.
2. INSTALL SPEED CONTROL
Use the included double-sided tape to mount the ESC.
3. INSTALL ON/OFF SWITCH
Choose a convenient place to mount the switch
where it will be easy to get to. Mount switch using
a piece of double-sided tape or with a screw through
the hole in the base of the switch housing.
4. INSTALL RECEIVER
Mount the receiver as far from the motor, power
wires, battery, and servo as possible. All of these
components emit radio noise when the throttle is
being applied. On graphite or aluminum, place the
receiver on edge with the crystal and antenna as
far above the chassis as possible. Mount the antenna
close to the receiver and trail any excess wire off
the top of the antenna.
STEP 1
HEAT SINK INSTALLATION
Heat sinks are required with the Reactor Reversible for
optimum performance and power handling. Included
with the Reactor are heat sinks to fit onto the ESC’s
three separate transistor tab banks.
1. INSTALL THE HEAT SINKS
Place ESC on a flat surface and press one heat sink
onto each of the individual transistor tab banks. Each
bank is separated by a plastic divider and is on a
different level than the adjacent banks.
The heat sinks should press onto the transistors with
a snug fit. If installed upside-down
(longer fins up)
or
shifted to one side, they will be too loose.
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 heat sinks.
2. DO NOT USE GLUE
Do not use glue or adhesives to attach the heat sinks to
the transistors.
3. DO NOT SHORT CIRCUIT HEAT SINKS
Each bank of heat sinks should never contact each
other or other conductive objects
(metal, etc.)
, or they
will short circuit and damage the ESC.
STEP 3
HOOK-UP INSTRUCTIONS
Refer to Set-Up photo on front page
1. INSTALL MOTOR CAPACITORS
Electric motors generate radio noise that can interfere
with your receiver and cause radio problems. Included
in the ESC accessory kit 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 to prevent ESC damage.
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
Positive (+) motor tab
Ground / motor can
Extra 0.1
µ
F capacitors are available in Novak kit #5620
2. IMPORTANT NOTE ABOUT SCHOTTKY DIODES
NO SCHOTTKY DIODES
Schottky diodes must NOT be used with reversible speed
controls. Using a Schottky diode will damage the speed
control and will void the warranty.
3. CONNECT SPEED CONTROL TO THE RECEIVER
After the proper input plug plastic has been installed
to match the receiver (See front page), plug the speed
control into the
THROTTLE CHANNEL
of the receiver.
4. CONNECT SPEED CONTROL TO THE BATTERY PACK
Plug the JST/Tamiya connector from the speed control
into a 6 or 7 cell battery pack (1.2 volts DC/cell).
5. CONNECT SPEED CONTROL TO THE MOTOR
Plug the bullet connector on the
YELLOW
wire of
the speed control to motor
positive
.
Plug the bullet connector on the
BLUE
wire of the
speed control to motor
negative
.
TIP:
Twist BLUE & YELLOW motor wires once or twice as they go
to the motor to reduce any radio noise emitted from power wires.
STEP 5
SPEED CONTROL PROGRAMMING
Speed control should be connected to receiver and to
a charged battery pack, and the transmitter adjusted.
1.
TURN ON THE TRANSMITTER
2.
TURN ON THE SPEED CONTROL
3.
PRESS AND HOLD THE ESC’S ONE-TOUCH BUTTON
With transmitter throttle at neutral, press and hold
the speed control’s
One-Touch
button until the sta-
tus
LED
turns solid red
.
4.
RELEASE ESC ONE-TOUCH 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-REVERSE 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
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-reverse position the status LED should be green
and the motor should be running full speed in reverse.
OPTIONAL SETTING FOR ESC WHEN REVERSE IS DISABLED
SET THE COAST BRAKE AT TRANSMITTER
Adjust
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, 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.
STEP 6
REVERSE DISABLE PROGRAMMING
Speed control should be connected to receiver and to
a charged battery pack, and the transmitter adjusted.
1.
TURN ON THE TRANSMITTER
2.
TURN ON THE SPEED CONTROL
3.
PRESS AND HOLD THE ESC’S ONE-TOUCH BUTTON
Press and hold the speed control’s
One-Touch
button
until the status
LED
turns from solid red to solid green
.
4.
RELEASE ESC ONE-TOUCH BUTTON WHEN LED IS GREEN
5.
PRESS ONE-TOUCH BUTTON TO ENABLE/DISABLE REVERSE
SLOW
red flash = reverse
ENABLED
FAST
red flash = reverse
DISABLED
NOTE: You must press the One-Touch button very soon
after the LED begins flashing red (slow or fast).
6.
LED WILL TURN GREEN THEN EXIT PROGRAMMING
Green LED indicates ESC is exiting programming mode.

and hold One-Touch button during programming
until status LED turns solid red.
ESC Will Not Go In Reverse
• Reverse circuitry disable––Refer to Step 6 to enable.
Steering Channel Works But Motor Will Not Run
• Speed control has thermally shut down––Allow ESC to
cool down––Use milder motor or smaller pinion gear.
• Check motor connections. Check motor and brushes.

• Receiver or antenna too close to speed control,
power wires, battery, or motor––Refer to Step 2.
• Bad connections––Check wiring and connectors.
• Motor brushes worn––Replace brushes.
• Excessive current to motor––Use a milder motor or
a smaller pinion gear.
Motor and Steering Servo Do Not Work
• Check wires, receiver signal harness wiring and color
sequence, radio system, crystals, battery and motor
connectors, and battery pack.
• Possible internal damage––Refer to Service Procedures.
Motor Runs Slowly / Slow Acceleration
• Check motor and battery connectors––Replace if needed.
• Bad battery or motor––Check operation with another.
• Incorrect transmitter or speed control adjustment––
Refer to Steps 4 and 5.
Motor Runs Backwards
