BRUSHLESS ESC FOR SHORT COURSE
INTRODUCTION
Congratulations and thank you for purchasing TORO, Short Course(SC), high performance
brushless motor electronic speed control. The TORO SC,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 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 - 4 LI-PO CELLS ONLY
Never use fewer than 2 or more than 4 LIPO cells in the vehicle's main battery pack. The
TORO SC handles up to 4S LIPO input (16.8 Volts MAX).
TRANSMITTER ON FIRST
Turn on the transmitter first THEN turn on the speed control.
INSULATE WIRES
Always insulate exposed wiring with heat shrink tubing or electrical tape to prevent short
circuits, which can damage ESC.
SHORT COURSE OR SMALLER
The TORO SC is intended for4x4 Short Course or Smaller.
BEFORE YOU BEGIN
1)Plan Speed Control Placement
Choose a location for the speed control that is protected from debris. To prevent radio
interference place the speed control as far away from the radio receiver as possible
and keep the power wires as short as possible.
1/ 8 2/ 8
Ver. 1.1 Ver. 1.1
Use a small piece of double-sided tape on the ON/OFF switch.
2)Solde ring
TIPS & TRICKS: Place the speed control upright and use double sided tape to secure it
to the bench. Doing so provides a stable work area and allows easy access to the solder
posts.
Attaching Wires to the Spe ed Cont rol:
Red wires are usually used to connect the speed control to
the positive battery terminal.
Black wire is typically used for the battery negative terminal.
Inspect the housing on the speed control next to each post
or refer to the diagrams to determine which color wire to
attach to each post.
Strip back the insulation of the wire by about 2.4mm to 3.2mm (3/32 to 1/8 and "pre-tin"
the wire by heating the end and applying solder until it is thoroughly covered.
CAUTION: Be very careful not to splash yourself with hot solder.
Place the tip of the iron in the notch on top of the post and apply a small amount of solder to
the post. When the solder has flowed, remove the soldering iron, wipe the tip clean and
apply a small amount of fresh solder to it.
Pre-Heat both the wire and the post.
Hold the wire so the tinned end is in contact with the notch of the post. Now touch the iron
tip to the wire and the post. Wait about 4 seconds for the solder to flow, and then remove the
iron while still holding the wire. You may let go of the wire after a second or two when the
solder sets.
Same techniques described in the preceding section may be used to solder the wires to the
battery or to battery connectors.
IMPORTANT: Take precautions if removing factory battery connectors. Connecting the
battery backwards will cause damage, and will void warranty. When soldering connectors to
a battery pack, cut only one wire of the battery pack at a time to ensure that the exposed
wires cannot short together.
HINT: If you are using connectors for both the battery and the motor, make sure that they
are not the same or that you have a male and a female attached to the speed control wires.
That way, you cannot accidentally connect the battery to the motor wires or vice versa.
Make sure that the connector ends will be mated together correctly, male to female, and that
the wire colors match red to red and black to black.
" ")
Prolonged/excessive heating of solder post (motor or ESC) will damage PCB.
Note: Make sure no wire strands have strayed to an adjacent solder post, this will result in
short-circuiting & severe ESC damage, which will void the warranty.
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.

After calibr ation ESC will ring s 1 secon d indicating that i t 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 SC
controller all at the touch of a single button. No computer needed. Simply disconnect the Fan
lead from ESC and connect program lead form program card to ESC’s program connector.
Power the programming card as described below. Press and release button to move
between settings. Press and hold button to change the value for that setting. All the settings
will show on the programming card at once. Can't get any easier!

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.
How to Enter Programming Mode
Plug Battery into the TORO SC
Hold full throttle on your transmitter
Turn the ESC switch ON
TORO SC flashes LED and rings once
Wait few seconds.
TORO SC flashes LED and rings 1 second indicating that it is ready for CALIBRATION mode
Continue to hold full throttle
TORO SC flashes LED while beeping
Wait another few seconds
TORO SC flashes LED and rings 1 second
TORO SC flashes LED while beeping indication that you are in PROGRAMMING mode
Let trigger go neutral (Centre)
2)Auto-Lipo(D)*
At this point the TORO SC 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.
5/ 8 6/ 8
Ver. 1.1 Ver. 1.1
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 nine 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.
FAN REPLACEMENT
The TORO SC comes with a 30mm x 30mm x 10mm 5V Brushless fan.
Should the fan need replacement, simply unplug the fans power wire
from the TORO SC, remove the 4 screws that secure the fan and
remove the fan cover.

TROUBLE SHOOTING
Problem: My TORO ES C may or ma y not arm, but it will no t calibrate to my tra nsmitter
Solution: Mo st calibration is sues ca n be solved by changi ng settings on the tr ansmi tter.
Make sure you ha ve both your thrott le and brake endpoints (ca lled EPA or
ATV on your radio ) on the throttle cha nnel ou t to between 100 to 120 %. Make
sure if you have a F utaba or Futaba mad e transmitter to have the th rottle
channel set to t he reversed posit ion.
Problem: My ES C calibrates for th e full th rottle and full bra ke positions but wo n't
calibrate to t he neutral thrott le position. (Orange LED k eeps flashing)
7/ 8 8/ 8
Ver. 1.1 Ver. 1.1
Solution: Try moving the thro ttle trim one way, then the other (u sually towards the
throttle side is best). If your tra nsmitter has a 50/50 and 70/30 setting for the
throttle, set it for 50/50 and retr y cal ibration. Also, if you have changed the
dead band to a narrower band you may want to try going back t o the "nor mal"
setting.
Problem: My vehicl e acts like it has turbo lag (poor acceleration/pun ch fo r the first
few feet or yards)
Solution: Mak e sur e you're using high quality batterie s and a batt ery connector capable
of high amp flow (40-100 amps). This behavior is very typi cal of a bat tery pack
that is having difficulty providin g the p ower your vehicle/system requires for
top performance. Use co pper bars to connect cells rather than welded tabs.
Copper bars have a much lower resis tance.
Problem: My batter y pack is pl ugged into the ESC and nothing is working
Solution: Mak e sur e the E SC's receiver plug is plugged into channe l 2 on the rec eiver,
and that it's plugged in with the correc t orientation. Double check you r sol der
connections on the batt ery plug, and make sure the battery is showing good
voltage.
