MOUNTING INSTRUCTIONS
For proper speed control operation and programming
set the transmitter adjustments as follows:
1. Set HIGH ATV or EPA to maximum setting.
[Controlsamount of throw fromneutral to full throttle]
2. Set LOW ATV, EPA, or ATL to maximum setting.
[Controlsamount of throw from neutral to fullbrakes]
[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 and50% brake/reverse throw (or 5:5).
[Adjustspistol-grip transmitter’sthrottle trigger throw
on electronic/digital transmitters]
7. Set MECHANICAL TRIGGER THROW ADJUSTMENT
to 1/2 throttle and 1/2 brake/reverse throw.
[Adjustspistol-grip transmitter’sthrottle 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 operatingtemperaturesmean 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
apiece 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
farabovethechassis 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
optimumperformanceand 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
ontoeach of the individual transistortab banks. Each
bank is separated by a plastic divider and is on a
different level than the adjacent banks.
Theheatsinksshould 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
otheror 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
withyour receiver and cause radioproblems. Included
in the ESC accessory kit are three 0.1µF (50V) non-
polarized,ceramic capacitors. These capacitors must
beinstalledon everymotortohelp reduce the noise
generated by the motor and to prevent ESC damage.
Solder 0.1µF (50V) capacitors between:
• POSITIVE(+) motortab & 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.

Extra0.1µFcapacitors areavailable inNovak kit #5620
2. IMPORTANT NOTE ABOUT SCHOTTKY DIODES
NO SCHOTTKY DIODES
Schottkydiodes must NOT be used withreversiblespeed
controls. Using a Schottky diode will damage the speed
control and will void the warranty.
3. CONNECT SPEED CONTROL TO THE RECEIVER
Afterthe proper input plug plastic has beeninstalled
tomatch the receiver (Seefront page), plug the speed
controlintotheTHROTTLE 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
tothe motor toreduce any radionoise emitted frompower 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 programmingeven
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
atneutral and proper programming hasbeen 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
andthemotor 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.
