ESC and Transmitter Calibration

1. Begin with the transmitter and receiver binding complete.

2. Set your transmitter’s throttle channel to 100% travel and trim to neutral.

3. Turn on your transmitter and connect a battery to the ESC but don’t power it on.

4. Press and hold the Set button while turning on the ESC. When the red LED

begins to ﬂ ash, release the Set button. The ESC will enter programming

mode if the button is pressed for more than three seconds.

TIP: The red LED should be ﬂ ashing when the ESC enters calibration mode. If

the green LED is ﬂ ashing the ESC is in programming mode.

5. Leave the throttle trigger at the neutral position, then press and release the Set

button. The red LED will stop ﬂ ashing, the green LED will ﬂ ash one time and the

motor will make a tone to indicate the neutral position has been accepted.

6. Hold the throttle trigger at the full throttle position then press and release

the Set button. The green LED will ﬂ ashe twice and the motor will make two

tones to indicate the full throttle position has been accepted.

7. Hold the throttle trigger at the full brake position then press and release the

Set button. The green LED will ﬂ ash three times and the motor will make

three tones to indicate the full brake position has been accepted.

The motor will operate normally after calibration is completed.

Normal Servo Signal (PWM):

The Firma ESCs are fully compatible with common RC receivers and will use a

conventional PWM signal for basic operation.

Installation and Wiring

1. Mount the ESC and power button with double sided tape or hook and loop material.

Select a location to mount the ESC with good ventilation for cooling.

The ESC

mounting tabs can also be used to secure the ESC to the vehicle‘s chassis.

2. Connect the three motor wires from the ESC to the motor wires in any order.

In the event the motor spins the wrong direction, reverse any two wires.

3. Connect the throttle servo lead to the throttle port on your receiver.

4. Secure all wiring so it is protected from damage or being caught by moving parts.

NOTICE: Do not connect a dedicated receiver battery to the receiver along with the

ESC. When the ESC is turned On it will provide the receiver with 6V regulated power

from the main battery through the throttle connection. The ESC may be damaged if

the receiver is also connected to a dedicated receiver battery.
