Thank you for purchasing Cheetah 1/10 CS60 60A 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.


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 4-9 cells NiMH or 2-3 cells LiPo battery.


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
Incorrect 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.

We will not be responsible for any damage caused by non-compliance with above



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
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.
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.




Support Both Sensor or Sensor-less Brushless Motor


For 1/12 & 1/10 Scale Car

Connect the motor sensor harness to ESC. Insert the 6 pin connector on the end of the
motor's sensor wires into ESC's sensor harness socket.
Connect Throttle lead to ESC and other end to the Receiver (Throttle Channel, Ch2)
Connect the motor and the ESC.
Connect ESC to batter pack.

Program Card


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.
