SPECIFICATIONS
• operated by microprocessor, fully digital controller
• bi-directional ESC for use with up to 300-size motors
• smooth linear regulation of drive from 0% to 100%
• installed electronic brake 100%
• brake responds only after switching from the forward movement
to the reverse movement, braking time is 0.1 sec, after
end of braking the ESC will automatically switch to reverse
• battery elimination circuitry (BEC)
WARNING!
•This product is not suitable for children except under the direct
supervision of an adult.
• First-time users should seek advice from people who have experience
with RC cars and who have properly installed and used electronic
speed controllers.
• Never leave your model unattended with the battery connected.
• Be sure that your operating frequency is clear before turning on
or running your model, and never share the same frequency with
somebody else at the same time. Ensure that others are aware of the
operating frequency you are using and when you are using it.
• Always turn on your transmitter before you turn on the ESC or connect
the battery pack. Always turn off the ESC or disconnect the battery
pack before turning off your transmitter.
• Immediately after using your model, do NOT touch the model's
electronic equipment, as it may be hot.
• When you connect the battery and turn on the electronics, make sure
your car is physically prevented from moving or getting away from
you and causing damage.
• Technical faults of mechanical or electrical nature may cause the
motor to jump into motion unexpectedly, which can cause serious
damage or injury.
NEVER:
• This ESC is designed to use with micro stock motors and micro motors
up to size 300. Never use this ESC with motors larger than 300 as you
will ruin the ESC.
• Never use this ESC with brushless motors.
• Never run your model car in water, snow or wet conditions. This could
result in an electronic device shorting out and causing a fire.
• Avoid incorrect connections. Reverse polarity will damage the ESC and
void your warranty.
• Do not let output tabs (where wires connect to ESC) touch any other
surface. Never touch the output tabs with any metal parts or conducting
material. This may short your ESC and void your warranty.
• Do not attach a Schottky diode to your ESC or motor. This will ruin the
forward/reverse ESC and void your warranty.
SCHOTTKY DIODE
Do NOT use the Schottky diode on the motor when using XMC300R speed controller.
The Schottky diode can be used only with pure forward/brake speed controllers. Using Schottky diode on your motor
when using XMC300R speed controller will destroy the ESC and thus will void the warranty immediately.
INSTALLATION TIPS:
• Mount the ESC in the model car using a double-sided foam tape.
• When installing the ESC in an XRAY model racing car use the supplied screws to install it in the designed location.
• Provide plenty of cooling openings in the car body; this increases the performance and extends the life of electronic components.
• Install the ESC in a location where it is protected from crash damage.
• The ESC should be installed in such a way that you have easy access to the buttons.
• Ensure that there is an adequate distance (at least 3cm) between the ESC and power cables and the receiver or receiver aerial. Avoid direct contact between all power system
components and the receiver or aerial, as this can cause interference. If you encounter interference problems, reposition the components in the model.
• The aerial should be run vertically up and away from the receiver. Avoid contact with any parts made of carbon fiber or metal. If the aerial is too long, don't coil up the
excess length. Make sure to read and understand the instructions supplied with your radio control system.
CONNECTIONS
The ESC is connected to various components:
MOTOR – red and black wire with female plug,
RECEIVER - black connector
BATTERY PACK - red connector.
The battery used may be 4.8V (4-cell), 6V (5-cell), or 7.2V (6-cell).

• All cables and connectors must be effectively insulated. Short circuits can
ruin your ESC, servo, or battery pack.
• Use only polarized connectors for ESC connections.
• Do not reverse the polarity of the ESC connections.
• If a fault should occur, this could cause a fire in the model and threaten
anything in the vicinity.
• Do not allow any metal part to short circuit the batteries, ESC, or other
electrical/electronic device on the model.
• The ESC is designed exclusively for use in battery-operated radio-
controlled models. No other usage is permissible.
• Like all electronic components, the ESC must not be exposed to water or
fire.
• Do not stall the motor. The ESC will fail within seconds if power is applied
to the motor when the car cannot move.
• When the motor is connected to the ESC, do not connect a separate
battery to the motor to run it. This will damage the ESC and invalidate the
warranty.
• This speed controller is NOT waterproof.
• Always make sure that enough air can get to the speed controller so that
good cooling conditions are achieved.
• Do not modify any parts of the ESC and especially do not modify or change
any of the wires otherwise you void warranty.
• Never leave your model car unattended when the battery is connected.
If a fault should occur the result could be a fire in the model which could
destroy anything else in the vicinity and injury persons.
• Never wrap your ESC in foil or film; air must always be able to flow round
and over the unit.
• Never change the polarity of the receiver plug.
• Never use water or chemicals to clean the ESC.
• Never expose the ESC to extreme heat or cold temperatures.
• Never touch the ESC and any of its parts after a run. It could be very hot
and injure you.
• Never dry the ESC in a microwave oven.

INSTALLATION
Follow these steps after you have installed the ESC in your car:
1. Make sure the white switch on the ESC case is in the OFF position.
2. Connect the ESC to the receiver's Channel 2 slot.
3. Connect the ESC to the motor: red wire to positive (+) red male wire on
the motor, black wire to negative (-) black male wire on the motor.
4. Check all wiring and connections before you connect the ESC to a drive
battery. Extremely important: incorrect polarity will damage the speed
controller.
5. Connect the red connector of the speed controller to the battery pack.
The ESC is now ready for set-up.
