REACTOR SET-UP
REFER TO STEPS 1 THROUGH 6 ON BACK
The Reactor Reversible electronic speed control (ESC)
brings together all of the key elements to provide
you with the reliability and ruggedness you’ve come
to expect from Novak.
The Reactor Reversible features extra-tough HYPERFET III
transistors, and the original Novak One-Touch Set-Up
(The first, the easiest, & the fastest set-up in the world).
Exclusive Novak Polar Drive Technology provides
smooth throttle response and improved radio system
performance. Reverse Disable Circuitry locks out
reverse gear for racing or forward only operation,
and Smart Braking Circuitry brings the model to a
slow speed before hitting reverse to save your
vehicle’s gearbox and reduce speed control heating.
Other features include Novak’s Radio Priority Circuitry
to maintain steering control even after the battery
has discharged, Thermal Overload Protection, and
the Novak Input Plug System for compatibility with
all popular radio systems.

• 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 fewer than 6 or more
than 7 cells (7.2-8.4 volts DC) in main battery pack.
• MOTOR CAPACITORS REQUIRED Three 0.1
µ
F (50V)
ceramic capacitors (included) must be properly installed
on every motor to prevent radio interference. Additional
capacitors are available in Novak kit #5620.
• ALWAYS USE HEAT SINKS Three heat sinks are
included with the Reactor and must be used for
proper cooling and performance. Replacement
Reactor heat sinks are available in Novak kit #5406.
• NO REVERSE VOLTAGE! Reverse battery polarity can
damage speed control––Disconnect battery immediately.
• NO SCHOTTKY DIODES External Schottky diodes
must NOT be used with reversible speed controls.
Using an external Schottky diode will damage the ESC.
• DON’T LET TRANSISTOR TABS TOUCH Never allow
separate transistor banks to touch each other or any
exposed metal. This will create a short circuit and
damage the ESC.
• 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 and the heat sinks
can get extremely hot, so be careful not to touch them
until they cool. Supply adequate air flow for cooling.
• INSULATE WIRES Always insulate exposed wiring with
heat shrink tubing or tape to prevent short circuits.
CHANGING INPUT PLUGS
Included with the speed control is the Novak Input Plug
System to convert the Futaba signal harness to be
compatible with Sanwa, KO, Kyosho, JR, Airtronics Z,
and Hitec radios.
Refer to Figures 1-3 to convert plug.
Sanwa (A)
KO
Kyosho (KYO)

FIGURE 1 With a small standard screwdriver, press on each
of the three metal prongs until the wires are easy to remove.
Remove wires.
FIGURE 2 With the screwdriver, carefully lift each of the metal
locking tabs to the angle shown.
FIGURE 3 Insert each pin into the correct plug slot. Each pin
should “click” into place.
(Sanwa plug shown)
The locking tab must not extend
outside the plastic plug housing.
WHT = White wire terminal (signal)
BLK = Black wire terminal (negative)
RED = Red wire terminal (positive)
CAUTION Improper installation of these wires may cause
damage to the receiver, servo, and speed control.

A. INSTALL SPEED CONTROL
Use double-sided tape to mount speed control in
model where the power wires are neatly routed
away from the receiver and antenna. For more
details refer to Step 2.
B. CONNECT SPEED CONTROL TO RECEIVER
Plug the speed control input signal harness into the
throttle channel of receiver. Make sure the proper
plug plastic is installed on ESC signal harness. Refer
to Changing Input Plugs.
C. CONNECT SPEED CONTROL TO BATTERY
With the speed control’s switch in the off position,
plug the JST/Tamiya connector from speed control
into a 6 or 7 cell battery pack (1.2 volts DC/cell).
D. TURN ON TRANSMITTER POWER
Refer to Step 4 for transmitter adjustments.
E. TURN ON SPEED CONTROL
Slide
ON/OFF
switch to ON position.
F. PRESS AND HOLD ONE-TOUCH BUTTON
With the transmitter throttle in neutral position,
press and hold One-Touch button until the status
LED turns solid red, then release.
G. PULL THROTTLE TO FULL-FORWARD POSITION
Hold until status LED turns solid green.
H. PUSH THROTTLE TO FULL-REVERSE POSITION
Hold until status LED blinks green, then return
throttle to neutral position. LED will then turn solid
red indicating proper programming and throttle is
in neutral position.
I. CONNECT SPEED CONTROL TO MOTOR
Turn off speed control then transmitter.
Plug the bullet connector on the YELLOW wire of
speed control to motor positive.
Plug the bullet connector on the BLUE wire of speed
control to motor negative.
J. KICK-UP A ROOST!
Turn on transmitter and then speed control.
Please refer to Step 6 for instructions on disabling the
reverse portion of the speed control for use when racing.
