25 Amp Brushless Sensorless Speed Control for RC Cars/Trucks
Thank you for purchasing the most technologically advanced brushless electronic speed
controller in the world for RC cars and trucks! Please take the time to read over these
instructions to ensure you get the most from your Mamba brushless power system and enjoy
years of trouble-free operation.
1.0 Features of the Mamba- 25™ :

2.0 Making Connections on your Mamba 25 Power system
Tools required:
Wire cutters
Wire stripper (optional)
Soldering iron (30-40W)
2.1 Adding a battery connector to your Mamba 25:
The battery connector must be added to the power side of the controller (blue capacitor,
receiver connector, and red and black wire side). The red wire is the positive (+) lead, and
must match up to the positive lead from your battery. The black wire is the negative (-) lead,
and must match up to the negative lead from your battery. The polarity MUST BE
CORRECT or the controller will be damaged from reversed polarity.
Strip just enough insulation off of the battery wires to solder on your battery connector to the
controller leads. After the connector is soldered and insulated (shrink tubing or electrical
tape) check it ONE MORE TIME to make sure the polarity is correct before you plug in a
battery.
2.2 Plugging in motor leads:
With a brushless system, there is no polarity on the MOTOR side of the controller. Simply

Warning!
High power motor systems can be very dangerous! High currents can heat wires and batteries, causing
fires and burning skin. Follow the wiring directions carefully! Models equipped with high power motors can cause serious
injury. Even though this controller is equipped with a safety arming program, you should still use caution when
connecting the main battery and always check battery polarity.
plug in the three connections between the CM20 motor and Mamba 25 controller. After the
throttle calibration routine below – if the motor runs backwards with foreword throttle,
simply swap any two of the motor/controller connections and it will reverse the rotation of
the motor.
2.3 Connecting to the receiver:
Connect the receiver lead (the three color wires with a connector on the end) to the throttle
channel on your receiver (usually channel 2). Do not connect a battery to the receiver, as the
Mamba- 25™ will supply power to the receiver and servo through the receiver connector.
3.0 Communicating with your new Mamba 25:
When programming your Mamba 25, it will tell you where you are in the current
programming sequence using a combination of sounds and LED flashes. The controller
generates sounds through the motor, so it's best to have your motor connected whenever you
attempt to configure your Mamba 25. The controller signals the motor to make two types of
sounds; a longer multi-toned ring (hereafter referred to as a ring), and a short beep (hereafter
referred to as a beep). The controller also has THREE (3) LED's (red, yellow, and green)
which will flash to give you further indication as to what programming state the controller is
in.
3.1 Calibrating the Mamba 25 to YOUR transmitter:
IMPORTANT NOTE: Calibration is required for the very first use of the Mamba 25
or whenever used with a new/different transmitter.
The Mamba 25 contains a throttle calibration feature that you'll want to use the first time you
power it up with a new/different transmitter. Performing this exercise will teach the
controller how your transmitter works.
