Version 2
1/10 SCALE BRUSHLESS ESC
Leopard 60A ESC is high performance 1/10 Scale Brushless Motor Electronic Speed Control.
The speed controller is specially designed to offer high power and high efficiency combined
with low weight and compact dimensions.
INTRODUCTION
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.
SAFETY NOTE
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!
1/10 SCALE
The Leopard 60A ESC is intended for 1/10 scale vehicles.
INSULATE WIRES
TRANSMITTER ON FIRST
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
Leopard 60A ESC handles up to 3S LIPO input (12.6 Volts MAX).
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.
NO REVERSE VOLTAGE!
Reverse battery polarity can damage ESC & void warranty. Disconnect battery immediately
if a reverse connection occurs.
Turn on the transmitter first THEN turn on the speed control.
Always insulate exposed wiring with heat shrink tubing or electrical tape to prevent short
circuits, which can damage ESC.
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.

How to Calibrate ESC
IMPORTANT NOTE: Calibration is necessary for the first use of the ESC, or whenever used
with a new/different transmitter.
ESC/TRANSMITER CALIBRATION
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.
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 ring the
initialization tones.
Wait 2 seconds
The motor will rings 4 times indicating full throttle measured.
Whiles beeping,indicating it's time to push full brake.
Move throttle trigger to full brake and wait few seconds, the ESC will
rings 4 times indicating full brake measure.
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 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 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.
V2
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.
Instruction for Program Card
2) Manual Programming
You must answer "yes" (full throttle) or "no" (full brake) to the setting
values as they are presented by Leopard 60A ESC. When you enter
programming mode the ESC will emit a sequence of beeps 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.
Manual Programming Leopard 60A ESC is as simple as answering a few questions. The Leopard
60A ESC asks questing by beeping a setting number, followed by the possible setting values.
There are eight settings that can be programmed in the Leopard 60A ESC.
Yes(full throttle)
No(full brake)
Plug Battery into the Leopard 60A ESC
Hold full throttle on your transmitter
Turn the ESC switch ON
Leopard 60A ESC rings once
Wait few seconds
Leopard 60A ESC rings 4 times indicating
that it is ready for CALIBRATION mode
Continue to hold full throttle
Leopard 60A ESC beeping
Wait another few seconds
Leopard 60A ESC rings 4 times
How to Enter Programming Mode
ESC PROGRAMMING
1) Programming Card(Optional Part)
Programming Card allows you to modify the most commonly used settings in your Leopard
60A ESC 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!

Programmable Features
Note: Factory Defaults are indicated by asterisk (D)*
At this point the Leopard 60A ESC 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 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.

Problem: My LEOPARD ESC may or may not arm, but it will not calibrate to my transmitter
TROUBLE SHOOTING
Solution:
Solution:
Problem: My battery pack is plugged into the ESC and nothing is working
Problem:
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.
The Leopard 60A ESC Brushless ESC is guaranteed to be free from defects in materials or
workmanship for a period of 90 Days from the original date of purchase (verified by dated,
itemized sales receipt). Warranty does not cover incorrect installation, components worn by use,
damage to case or exposed circuit boards, damage due to timing, damage from using more than
3 Li-Po cells input voltage, cross-connection of battery/motor power wires, overheating solder
tabs, reverse voltage application, improper use or installation of external BEC, damage resulting
from thermal overload or short-circuiting motor, damage from incorrect installation of FET servo
or receiver battery pack, tampering with internal electronics, allowing water, moisture, or any
other foreign material to enter ESC or get onto the PC board, incorrect installation/wiring of
input plug plastic, allowing exposed wiring or solder tabs to short-circuit, or any damage caused
by a crash, flooding or natural disaster. Because SKYRC has no control over the connection &
use of the speed control or other related electronics, no liability may be assumed nor will be
PRODUCT WARRANTY
My ESC calibrates for the full throttle and full brake positions but won't calibrate to
the neutral throttle position.
Try moving the throttle trim one way, then the other (usually to wards 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 "normal" setting.
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.
