MICRO REVERSIBLE ESC

PRECAUTIONS

NOVAK’S MICRO REVERSIBLE IS THE SPY

...and this spy gear is high-tech. Designed with ultra-small

surface mount technology and all the standard features

found in Novak electronic speed controls, the SPY gives

you the ultimate controller for the right price.

The SPY is capable of handling 4-7 cells and up to 280 size

motors that are used in 1/18th & 1/24th scale Micro R/C cars

The rugged 5V/1A B.E.C. handles most any servo

with ease,

and Radio Priority Circuitry means you’ll maintain

control of

that servo even after the battery has discharged.

Smart Braking Circuitry brings the car to a slow speed

before throwing it into reverse to reduce ESC heating, and the

electronics will continue to stay cool with the Polar Drive

Technology that also improves radio system performance.

The Reverse Disable Circuitry lets you lock-out reverse for

racing. And of course, Novak’s original One-Touch Set-Up

means your spy gear is the easiest to program.

• 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.

• MICRO SIZE MOTORS ONLY Use only motors that are

intended for use with 1/18th scale or smaller R/C cars.

Never use larger than a 280 size motor

(1” diameter/3-5 watts)

• 4 TO 7 CELLS ONLY Never use fewer than 4 or more

than 7 cells

(4.8-8.4 volts DC) in the main battery pack.

• NO REVERSE VOLTAGE! Reverse battery polarity can

damage speed control––Disconnect battery immediately.

• NO SCHOTTKY DIODES External Schottky diodes must

NEVER be used with reversible speed controls. Using an

external Schottky diode will damage the ESC.

• DISCONNECT BATTERIES WHEN NOT IN USE Always

disconnect the battery pack from the speed control when

not in use to avoid possible short circuits.

• TURN TRANSMITTER ON FIRST Turn on your

transmitter’s power before the speed control so you will

have control of the radio equipment.

• INSULATE WIRES Always insulate exposed wiring with

heat shrink tubing or electrical tape to avoid short circuits.

STEP 1 CHANGING INPUT HARNESS

The SPY ESC comes with the industry standard input harness

connector that works with all major radio brands. However,

with some older style receivers the wiring sequence in the

plastic connector needs to be changed. This is an important

step, because the electronics inside the receiver may be

damaged if the wiring sequence is incorrect. Changing the

sequence is easy to do, as described below.

JR • Hitec • New KO • Airtronics Z

JR, Hitec, Futaba, new KO, & Airtronics Z

receivers do

not

need to change the sequence of the ESC's input harness

wires.

New Airtronics Z receivers

have blue plastic cases & new KO

cases have tabs on the input harness openings as in Figure 1.

• Insert the input plug into the receiver with the BLACK

wire toward the outside edge of the receiver case.

Old-style KO • Old-style Sanwa/Airtronics

If your receiver is an older KO or Sanwa/Airtronics, you must

change the sequence of the ESC's input harness wires. Old

Sanwa/Airtronics cases are black in color. Old KO cases do

not have the tab openings, as in Figure 2 above.

• Interchange the red and black wires in the plug plastic of

the ESC's input harness as shown below.

• Insert the input plug into the receiver with the RED wire

toward the outside edge of the receiver case.

STEP 2 MOUNTING ELECTRONICS

1. DETERMINE BEST ESC MOUNTING LOCATION

The ESC should be positioned away from the receiver

and antenna as shown in the Set-Up photo below. Choose

a mounting position that will keep the power wires from

obstructing movement of suspension or the motor pod.

2. INSTALL SPEED CONTROL

Use the included double-sided tape to mount the ESC.

3. INSTALL ON/OFF SWITCH

Determine a convenient place to mount the switch where

it will be easy to get to. Mount the 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. These components all 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.
