2.0 Connection
Tools and Parts required:
Wire cutters
Wire strippers
Soldering iron (40W)
Rosin core electrical solder
Battery connector
2.1 Adding a battery connector
The battery connector must be added to the power side of the controller. The red wire is
positive (+) and black wire is negative(-). The polarity MUST BE CORRECT or the controller
will be damaged. Strip enough insulation off of the battery wires to solder on your battery
connector to the controller leads. After the connector is soldered and insulated check one more
time to make sure the polarity is correct before plugging in a battery.
2.2 Plugging in a motor
With a BRUSHED motor, simply solder supplied 4mm bullet plugs onto the motor wires, then
insulate. After calibration- if the motor runs backwards while the ESC light is green, swap any
two motor wires to reverse the direction of the motor.
2.3 Connecting to the receiver
Connect the receiver lead to the throttle channel on your receiver. Do not connect a battery or
external BEC to the receiver unless the red wire is removed from the ESC’s receiver lead. Be
sure to insert plug with correct polarity.
3.0 Calibration
The ESC uses a combination of sounds and LED flashes to tell you where you are in the
calibraton sequence. The ESC generates sounds through the motor, so when calibrating your
ESC to a transmitter it is best to have a motor plugged in.
3.1 Calibrating the ESC to YOUR transmitter
Note:
When running two ESCs, they
CANNOT
have the battery power wires connected during
calibration or programming. It will cause problems with the second ESC.
) Remove pinion from motor to prevent accidents
2) Plug in battery
3) Hold full throttle on transmitter before ESC arms
4) ESC will beep and begin flashing red rapidly to indicate storage of full forward throttle
position
5) Hold full reverse on transmitter until beeping changes
6) ESC will beep rapidly with no lights to indicate storage of full reverse throttle position
7) Position throttle in neutral position
8) After about two seconds, ESC will store neutral position
