Thank you for purchasing TORO SC120 Brushless Sensored ESC from SKYRC
TECHNOLOGY CO.,LTD. Please read the Instruction Manual thoroughly before you use the
product. These operating instructions are designed to ensure that you quickly become
familiar with its features and functions and make full use of this product.
FEATURES
Well-performed throttle and brake control function could control the punch/brake rate by
point and the point can be set by user. The precision of the punch/brake rate is 1%. And
the user could also custom the throttle/brake curve.
Punch control is reasonable and precise and it can meet different customers' request for
line and power.
Users could modify the setting, monitor the ESC and motor status at any time by smart
phone via Bluetooth Module (Bluetooth Module adaptor can be purchased separately,
which is not included in the package).
Red copper connector is used internal of the ESC. It can decrease the internal
resistance at high current situation.
The circuit is managed by intelligent thermal management kernel algorithm. The dynamic
loss can be reduced effectively when the motor is running at high speed or the user
changes the motor speed frequently so that the motor can be more stable when running.
Heat transfer: The internal resistance can be reduced by laminated copper stack control
technology and cooling fan design so that the dynamic thermal equilibrium can be got. In
this case, the aluminum heat sinks can works effectively.
The users could set and store 10 sets of profiles in the ESC. These data could be called
out at any time without any special program setting. All the setting can be exported or
imported so that the user could compare and analyze.
Safety features: low voltage protection, motor and ESC overheat protection and signal
lost protection.
It can be programmed by Program Box(SK-300046), PC via SKYLINK(SK-600013) or
smart phone via Bluetooth Module(SK-600058).
The firmware can be updated by connecting the ESC with PC or smart phone.
INTRODUCTION
SAFETY NOTE
It is not a toy and suitable for users older than 14 years old.
Never allow water, moisture, oil or other foreign materials to get inside ESC, motor, or on
the PC Boards. It may damage the ESC completely.
Never disassemble the ESC and modify the components on the PC Boards.
Suggest using the original wires and connectors which are packed in the box.
Never solder one part for more than 5 seconds as some components will get damaged
by high temperature.
Never run the ESC w/o load at full throttle and it may damage the bearings and other
moving parts.
Please make sure the location where to fix the ESC has good airflow ventilating so that
the heat could dissipate quickly.
To avoid short circuit, please keep the ESC connectors far away from other metal parts.
Never connect the battery in polarity in reverse.
Please remove the pinion gear 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
Before you switch on the ESC, please make sure all the cables are well solder with the
connectors (It is easy to get loose when running) . What's more, make sure the cables
not touch the moving parts.
Electronic motor timing will increase the temperatures of ESC and brushless motor. Use
extreme caution when setting up and testing your application to avoid overloading and
overheating.
Incorrect Boost and Turbo timing setting may cause permanent damage to the ESC and
motors. Please choose proper ratio and timing setting according to motor's instruction.
To avoid signal interference, please always turn on the transmitter first THEN turn on the
speed control. Do the opposite when powering it off.
Never use faulty accessories, e.g. motor which may damage the ESC. Always insulate
exposed wiring with heat shrink tubing or electrical tape to prevent short circuits, which
can damage ESC too.
Always disconnect the battery pack from the speed control when not in use to avoid
short circuits and possible fire hazard. When the ESC is switched off, there is still small
current and it may cause over discharge of the battery after some time.
The ESC can support 6-12 cells NiMH or 2-4 cells LiPo battery.
We will not be responsible for any damage caused by non-compliance with above
instruction.
Note:
Mount Speed Control in Vehicle
Use double-sided tape to mount the speed control in vehicle (do not use CA glue). Use
double-sided tape to mount the switch where it will be easy to access. Select a position
where it will not get damaged or get switched OFF during a crash or roll-over.
You may use the mounting plate(included) to fix the ESC to the chassis.
Soldering
Cut the ESC's BLUE, YELLOW & ORANGE silicone motor power wires to the desired length
and strip about 3.2mm-6.35mm (1/8”-1/4”) of insulation from the end of each wire. “Pre-
tin”the wire by heating the end and applying solder until it is thoroughly covered.
CAUTION: By very careful not to splash yourself with hot solder.
Place the ESC's BLUE Phase ‘A’ motor wire onto motor's ‘A’ solder tab and solder. Use
soldering iron to apply heat to exposed wire; begin adding solder to tip of soldering iron and
wire. Add just enough solder to form a clean and continuous joint from the plated area of the
solder tab up onto the wire. Solder the ESC's YELLOW Phase‘B’ motor wire to the motor's ‘B'
solder tab and Solder the ESC's ORANGE Phase ‘C' motor wire to motor’s ‘C’ solder tab.
PREPARATION
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. Select a location that has good airflow
ventilating. If the ESC gets air flow, it will run cooler; and that means it will be more
efficient.

ESC CALIBRATION
Calibration is necessary for the first use of the ESC, or whenever used with a new/different
transmitter. 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 your transmitter.
How to calibrate the ESC?
ESC switch OFF.
Connect the ESC to the battery and the motor.
Turn on the transmitter.
Press and hold the ESC switch for few seconds, the motor will ring long beep once. After
that, the red LED will blink the motor will ring like beep-beep-beep… in a row which indicates
it is time to set the neutral position, full throttle and full brake one by one. You could release
the ESC switch now.
Keep the throttle trigger in neutral position, press the ESC switch once, the
green LED will blink once then extinguish and the motor will ring beep once
which indicates the neutral position has been set.
Hold full throttle and press the ESC switch once, the green LED will blink
twice then extinguish and the motor will ring twice like beep-beep which
indicates the full throttle has been set.
Move the throttle trigger to full brake and hold full brake, press the ESC
switch once, the green LED will blink three times then extinguish and the
motor will ring three times like beep-beep-beep which indicates the full brake
has been set.
After the calibration is finished, keep the throttle in neutral position, the red
LED will stay ON, the ESC and the motor is ready to work.
ESC ON/OFF: When the ESC is OFF, press the switch once, the motor will ring beep once and
the red LED will blink, then the ESC is ready to work. When the ESC is on, press the switch
once, the LED will extinguish and the ESC is OFF.

After running at full load, the ESC will be very hot. In this case, please turn off the
ESC after it cools down.
When the motor is running, the ESC can't be powered off by pressing the switch;
when the motor stops working, the ESC can be powered off. In an emergency,
please disconnect the battery to power off the ESC.
