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.

How to Calibrate ESC

IMPORTANT NOTE: 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 you transmitter.

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!



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 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 1 second indicating
full throttle measured.

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.


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

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 1 second indicating full brake

Orange LED blinks whiles beeping, indicating it's time for neutral.
Relax trigger to neutral (center). The ESC flash the orange LED
rapidly to accept the neutral position.

ESC rings 1 second indicating neutral position measure.

After calibration ESC will rings 1 second indicating that it is armed.
