3650 Motor Specifications
NOTE: It is critical to always monitor motor temps on a new setup carefully until proper gearing setup is established and that gearing is lowered if temps
are too high (smaller pinion or larger spur). Motor may overheat and fail if geared too high even if voltage is within specs.

Begin to Use The New ESC:
Blue motor wire A , Yellow motor wire B and Orange motor wire C of the ESC can be connected with the motor wires in any order . If the
motor runs in the opposite direction desired, swap any two wire connections to reverse motor rotation.
Connection to the Receiver (NOTE: longer lead is for connection to receiver, shorter lead is for connection to program card)

Throttle Range Calibration (ESC must be calibrated at first use or anytime it is connected to a new radio):
1. Turn on the transmitter, then connect ESC with the battery pack and set the EPA/ATV (End Point Adjustment or Travel) value of the
throttle channel to the maximum setting for both brake and throttle (100%, 120% or 150% depending on radio). Set throttle channel to
REV when using Futaba radio.

2. Press and hold the “Set” button and switch on the ESC, release the button when the Blue LED turns solid. Pull the throttle trigger to full
throttle position, the red LED light will flash and motor beeps once when ESC confirms the position.
3. Push the throttle trigger to full Brake position (do not pause in neutral). Blue LED light will flash and motor beeps twice when ESC
confirms the position.
4. Release trigger to neutral position, both the Red LED and Blue LED blink and motor beeps three times when ESC confirms the position.
5. Turn off the ESC power switch to save the settings.
6. Turn the ESC back on. You are now ready to use the ESC.

Note: Highlighted settings are default settings.
Cutoff Voltage
ESC automatically detects the number of the cells
According to the type of your batteries, set up the type of the batteries and Low Voltage Cutoff Threshold via program card. The
ESC can detect the Voltage of the battery anytime and will lower the output power once the Voltage of the battery is lower than
the preset Low Voltage Cutoff Threshold.
When using NiMH or NiCd batteries you do not need to set a cutoff voltage to protect the batteries, and having a cutoff
voltage selected may cause ESC to cut out before batteries are drained.
Running Mode
Forward w/o Reverse
This is a Race setting - Reverse is disabled (most forms of racing do not allow reverse to be enabled).
Forward with pause then Reverse (DEFAULT)
General bashing or racing if reverse is allowed for the event. The Electronic Speed Controller requires 2 seconds of continuous neutral
from the transmitter prior to allowing reverse to operate, this is to protect the vehicle drivetrain.

Forward / Reverse
If this option is activated, the car can go forward and in reverse but will not have brakes.
Motor Timing
This option affects the power band and efficiency (run time) of an electric motor. The default is “Normal” and is a good starting point to
deliver power and provide good run time.
Very Low - Provides maximum efficiency with less power. Higher timing produces significantly more power but at the expense
of efficiency (less run time) and typically the motor will generate more heat. Each brushless motor will respond to timing
differently. Good for running around on paved, or harder surfaces, and racing with high KV rated or low-turn motors
Low - Provides power for running through soft surfaces, general use and longer run times.
Normal (Default) - Good mix of power and efficiency using any motor
High - More power than efficiency so run time will be reduced, and you should be monitoring motor heat. The higher KV or
lower turn motors will generate heat quickly using this setting. A safe high temperature range is 165F to 180F (74° - 82° Celsius),
going higher may damage your motor.
Very high - This is maximum power and must be used with caution.
Note: Any motor has the potential to over-heat in this setting. Frequently check the motor temperature and make sure you’re not
operating higher than 165° - 180° Fahrenheit (74° - 82° Celsius), which may damage your motor, or damage your Electronic Speed
Controller (ESC).
Initial Acceleration
Use this to limit the initial power that is sent to the motor when starting from a complete stop. Using the LOW option, the vehicle will
launch slower and provide the longest run times. When using the HIGH option, you will have wheel-spinning acceleration at the cost of
run time. This is also very tough on the batteries as the amperage draw can be very high. If your vehicle cuts out, hesitates or loses
radio control, you should consider setting this at a lower value.
Low - Using this option will provide longer run times and is easiest on the batteries. It is a good choice for beginners.
Medium - Medium requires more from your batteries, and is good for low traction surfaces.
High - This option will provide full acceleration and requires stout batteries to supply the load required in this setting.
Very High - This option will provide full acceleration and requires stout batteries to supply the load required in this setting.
Throttle Percent Reverse
Use this to limit the power available using reverse throttle. The lower the percent or level the less speed will be available in reverse. 20%,
30%, 40% ,50%, 60% (Default), 70%, 80%, 90% and 100%.
Throttle Limit
Use this to limit the power available using forward throttle. The lower the percent the less forward throttle speed will be available.
0% (Default), 20%, 30%, 40%, 50%, 60%, 70%, 80% and 90%.
Percentage Braking
Gives you the ability to have full control over the amount of brake your vehicle will have.
10%, 20%, 30%, 40%, 50% (Default), 60%, 70%, 80% and 100%.

Percentage Drag Brake
0% (Default), 4%, 8%, 12%, 15%, 20%, 25% and 30%.
The drag brake function provides the driver a set percentage of brake when you have the transmitter resting in neutral. This will create
the “feel” of a brushed motor.
Drag brake are used in racing to slow a vehicle as you let off approaching a corner versus the driver having to push the brake at every
corner.
Try working with this to get a sense of how you might use this for your track.
If you are running on a high traction track with tight corners, a stronger setting should work best.
If you are running in an open area, you will find a smaller percentage will result in better control.
If you are running in dusty or slippery surfaces, you will more than likely want to use the lowest option.
Motor Rotation
Normal (default), Reverse
Neutral Range
This setting adjusts the amount of “Deadband” off neutral on the throttle trigger. This is in Milli-Seconds (MS) and is the amount of
neutral when you pull the trigger.
The smaller the value the less “Deadband” or movement is required off-center for the ESC to begin throttle function.
Using a higher value for this setting will provide a wider Deadband.

LED Program card
1. The program card with LED display is easy to use and convenient to carry. All of the programmable functions are shown on the
program card (NOTE: some versions of program card have a BEC option listed on card but BEC is not adjustable on this ESC and
option will not appear when plugged into ESC).
2. With ESC off, connect shorter signal lead to plug on top right of program car, align black wire with “-“symbol. Turn on ESC.
The first programmable function will be shown, if an error occurs, check connections and try again.
3. If ESC is not connected to battery, the Program card should be connected with other power supply (battery), the range of power
supply is within 5.0-6.3V. Connect power to plug on top left of card with negative lead aligned with “-“ symbol.
4. Press the button “Menu” on the Program card to cycle through each programmable function. The number of the programmable
function will be displayed on the left side, and the current value will be displayed on the right side. Press “Value” to change the value
and press “OK”to confirm. When you are done making changes turn off the ESC and unplug the card, the modified settings will be
saved in the ESC’s memory.
5. Pressing the “Reset”button will restore ESC to default settings.
