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.

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.

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.
