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. 25 Amp Brushless Sensorless Speed Control for RC Cars/Trucks plug in the three connections between the CM20 motor and Mamba 25 controller.

1.0 Features of the Mamba- 25™ :
• Extremely Low Resistance (.0022 ohms per phase) Connect the receiver lead (the three color wires with a connector on the end) to the throttle • Up to 25 Amps continuous current, 50 amps surge channel on your receiver (usually channel 2). Do not connect a battery to the receiver, as the • Four to twelve cells, or 2 to 3 Lithium Polymer cells Mamba- 25™ will supply power to the receiver and servo through the receiver connector.

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 • Safe “power on” arming program ensures motor will not accidentally turn on Auto shut down when signal is lost or radio interference becomes severe 3.1 Calibrating the Mamba 25 to YOUR 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 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 black wire is the negative (-) lead, • Mamba flashes all LED’s and rings once and must match up to the negative lead from your battery.

Programming the Mamba-25™ is as simple as answering a few questions. The Mamba- 25™ asks questions by flashing a setting number, followed by the possible setting values. • Mamba flashes all led's and rings once There are five settings that can be programmed in the Mamba-25™: 1) Brake/Reverse Type, 2) Reverse Throttle Amount/Brake Strength, 3) Cutoff Voltage, 4) Timing Advance, 5) • Mamba flashes green led and rings 4 times indicating that it is ready for As the programmer, you must answer “yes” or “no” to the setting values as they are presented by the Mamba-25™. When you enter programming mode the controller will emit a sequence of beeps and yellow LED flashes 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 (e.g., Cutoff voltage type), and the second set of beeps indicates a Value (e.g 2 cell • Mamba flashes all LED’s and rings 4 times LiPo). Answering “no” to a setting value will cause the Mamba-25™ to ask for the next value. Answering “yes” to a setting value will store that setting in the Mamba-25™s • Mamba flashes yellow led while beeping indicating that you are in permanent memory. After a setting is stored, the Mamba-25™ will automatically continue to the next setting until all settings have been stored. NOTE: If you answer “no” to all values for a particular setting, the Mamba-25™ will keep whatever value had been At this point the Mamba will be flashing/beeping the following sequence: previously programmed. Only by answering “yes” to a value will the Mamba-25™ Beep – Pause – Beep… and then Repeats When answering a question, you will need to move the trigger to the yes (full throttle) This indicates that you are at Question 1 and it is asking to accept/reject Value 1. position or the no (full brake) position and keep it there for about 5 seconds. When the Mamba-25™ has accepted your answer it will confirm your reply by flashing the GREEN 3.2.3 Skipping Programming Sections – No change required

Release the trigger allowing it to go to Neutral to confirm that you are ready for the Mamba-25™ to ask the next Looking at the table on the last page you can see that Question 1 is ‘What reverse/brake type do you want?’ and that Value 1 is ‘Proportional Brake with Reverse Lockout’. We don’t want to change the current value of this option, so we will say no to each value thereby You are not required to continue through all five 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 Mamba-25™ and you’re ready to run.
