1/18 SCALE
BRUSHLESS ESC

YEAR

INTRODUCTION

Congratulations and thank you for purchasing TORO
Micro high performance sensorless 1/18 Scale
Brushless Motor Electronic Speed Control. The
TORO Micro,1/18 scale brushless ESC represents
a latest technologies, providing all the features and
robust design qualities.

SAFETY NOTE

WARNING: This is an extremely powerful brushless

motor system. We strongly recommend removing your
pinion gear for your own safety and the safety of those

around you before performing calibration and programming

functions with this system. Please keep your hands, hair,
cloth, clear from the gear train and wheels of an armed
high performance system.

WATER & ELECTRONICS DON'T MIX!

Never allow water, moisture, or other foreign materials

1/10

Ver. 1.02

to get inside ESC, motor, or on the PC Boards.

Water damage will void the warranty!

NO REVERSE VOLTAGE!

Reverse battery polarity can damage ESC & void
warranty. Disconnect battery immediately if a reverse
connection occurs.

DISCONNECT BATTERIES WHEN NOT IN USE

Always disconnect the battery pack from the speed
control when not in use to avoid short circuits and
possible fire hazard.

2 - 3 LI-PO CELLS ONLY

Never use fewer than 2 or more than 3 LIPO cells in the
vehicle's main battery pack. The TORO Micro handles
up to 3S LIPO input (12.6 Volts MAX).

TRANSMITTER ON FIRST

Turn on the transmitter first THEN turn on the speed
control.

1/18 SCALE

The TORO Micro is intended for 1/18 scale vehicles.

INSULATE WIRES

Always insulate exposed wiring with heat shrink tubing
or electrical tape to prevent short circuits, which can
damage ESC.

CONNECTIONS

Brushless Motor Wiring

Connect the blue, yellow and orange motor wires to the
motor. There is no polarity on the three ESC-to-motor
wires, so do not worry about how you connect them
initially. You may find it necessary to swap two wires if
the motor runs in reverse.

ESC/TRANSMITER CALIBRATION

IMPORTANT NOTE: Calibration is necessary for the
first use of the ESC, or whenever used with a
new/different transmitter.

For users with a Futaba Transmitter, you must reverse
the throttle channel signal on your transmitter. Please
refer to your Futaba instructions.

Individual transmitter's signals for full throttle, full brake
and neutral vary. You must calibrate your ESC so that it
will operate more effectively with you transmitter.

How to Calibrate ESC

ESC switch OFF.
Turn on the Transmitter.
Hold full throttle on your transmitter and turn the
ESC's switch ON.
Keep holding full throttle on the transmitter. The
ESC will flashes LED and ring the initialization tones.

Wait 2 seconds
Green LED blinks rapidly and

the motor will rings 4 times
indicating full throttle measured.

Red LED blinks whiles beeping,
indicating it's time to push full
brake. Move throttle trigger to
full brake and wait few seconds,
the ESC will blink red LED and
rings 4 times indicating full brake
measure.

Yellow LED blinks whiles beeping,
indicating it's time for neutral.
Relax trigger to neutral (center).
The ESC will now ring 4 times
and flash the yellow LED rapidly
to accept the neutral position.

ESC will blink LED and ring twice
indicating that it is armed.

From this point on, when you connect batteries and turn
on the switch, the ESC will give the initialization tone and
flash, and the arming tone will ring second or two later. If
the ESC is programmed for the Auto-Lipo setting, it will
beep the number of cells in you Lipo pack between the
initialization tones and the arming tones. After the arming
tone plays, the ESC will ACTIVE and will respond to the

throttle application.

ESC PROGRAMMING

1)Programming Card(Optional Part)

Programming Card allows you to modify the most
commonly used settings in your TORO Micro
controller all at the touch of a single button. No
computer needed. Simply connect the Programming
Card to the throttle lead of the controller and power
the programming card as described below. Click the
button to scroll through and change the indicated
settings. All the settings will show on the programming
card at once. Can't get any easier!

Instruction for Program Card

Turn off the ESC and disconnect the throttle lead from the receiver.
Connect the throttle lead from ESC to the 3 pin connector on the
Program Card.
Turn on the ESC to apply power to both ESC and Program Card.
All the current settings will be displayed on the correspond LEDs.
Press and release button to move between settings.
Press and hold button to change the value for that setting.
Turn off the ESC and disconnect the throttle lead from Program
Card and connect it back to the receiver.

2)Manual Programming

Manual Programming TORO Micro is as simple as
answering a few questions. The TORO Micro asks
questing by beeping a setting number, followed by
the possible setting values. There are eight settings
that can be programmed in the TORO Micro.

You must answer "yes" (full
throttle) or "no" (full brake)
to the setting values as they
are presented by TORO Micro.
When you enter programming
mode the ESC will emit a
sequence of beeps and LED
flashes that tell you which
programming step you are in.
There are two parts to the beep
sequence. The first set of beeps
indicates the 'Setting Number
(Question), e.g. Brake/Reverse
Type, and the second set of beeps
indicates a Setting Value,
e.g. Reverse Lockout. Answering
"No" to a Setting value will cause
the ESC to ask for the next value
in that section. After a "Yes" answer
is accepted, the ESC knows you aren't
interested in any other option in that
section, so it skips to the first option in
the next section.

Note: If you answer "no" to all Setting Values for a
particular Setting Number, the ESC will keep whatever
value had been previously programmed. Only by
answering "Yes" to a Setting Value will the ESC
store/change that value.

Yes(full throttle)

No(full brake)

How to Enter Programming Mode

Plug Battery into the TORO Micro
Hold full throttle on your transmitter
Turn the ESC switch ON
TORO Micro flashes LED and rings once
Wait few seconds.
TORO Micro flashes LED and rings 4 times
indicating that it is ready for CALIBRATION mode
Continue to hold full throttle
TORO Micro flashes LED while beeping
Wait another few seconds
TORO Micro flashes LED and rings 4 times
TORO Micro flashes LED while beeping indication
that you are in PROGRAMMING mode
Let trigger go neutral (Centre)

At this point the TORO Micro will be flashing/beeping
the following sequence: Beep-Pause-Beep... and
then repeats.
This indicates that you are at Question 1 and it is
asking to accept/reject value 1.

When answering a question, you will need to move the
trigger to yes (full throttle) position or the no (full brake)
position and keep it there for about 3 seconds. When the
ESC has accepted your answer it will confirm your reply
by flashing the LED and emitting a beeping tone. Release
the trigger allowing it to go to Neutral to confirm that you
are ready for ESC to ask you next question. You are not
required to continue through all eight programming options.
For example, if you wish only to change the Brake/Reverse
Type (Option 1) then after programming that setting you
can disconnect power from the ESC and you're ready to
run. Disconnecting the controller in the middle of
programming simply retains the values for the remaining
programming options that were previously set up.

TROUBLE SHOOTING

Problem: My TORO ESC may or may not arm, but

it will not calibrate to my transmitter

Solution:

Problem:

full brake positions but won't calibrate to
the neutral throttle position. (Orange LED
keeps flashing)

Solution: Try moving the throttle trim one way, then

setting.

Most calibration issues can be solved by
changing settings on the transmitter. Make
sure you have both your throttle and brake
endpoints (called EPA or ATV on your radio)
on the throttle channel out to between 100
to 120%. Make sure if you have a Futaba or
Futaba made transmitter to have the throttle
channel set to the reversed position.

My ESC calibrates for the full throttle and

the other (usually towards the throttle side
is best). If your transmitter has a 50/50 and
70/30 setting for the throttle, set it for 50/50
and retry calibration. Also, if you have
changed the dead band to a narrower band
you may want to try going back to the ormal

"n "

Problem: My battery pack is plugged into the ESC
and nothing is working

Solution: Make sure the ESC's receiver plug is

plugged into channel 2 on the receiver
with the correct orientation. Check solder
connections and make sure the battery is
showing good voltage.
