Thank you for purchasing the MC950CR . The MC950CR is a high-frequency drive FET speed control developed for
model electric cars. It is compact and light weight competition speed control, and uses a simple digital setting system.
Applicable motors
(Number of turns is criteria.)
Use the MC950CR with a motor with 2.5 turns or
sensor brushless more. ( With optional heatsink & fan)
*If a motor with a number of turns smaller than the above
is used, the heat protector and overcurrent protection
circuit may operate. The number of turns of the motor is
a criteria only. Depending on the running conditions, the
protection circuit may operate even if the condition
above is satisfied.

MOUNTING PRECAUTIONS
Important:
Because the MC950CR has pure race competition specifications, it is
designed so that it is difficult to operate the protection circuits. Use at an
overload may cause trouble. Incorrect power supply polarity or a power
supply or motor short circuit may cause the MC950CR to burn out.
Install the receiver and receiver antenna away from the
amp, motor cord, power cord, Nicd battery, and other parts
that carry a high current.
Metal and carbon chassis and other conductive parts
transfer switching noise. When mounting the receiver to
such a chassis, use thick double-sided tape to mount the
receiver as far away from the chassis as possible.
Insert the connectors firmly.
If vibrations while running cause the connectors to work loose, control
may be lost and an extremely dangerous situation may occur.
Do not run the vehicle in the rain or through puddles or on muddy
or snowy roads.
If moisture enters the amp, erroneous operation may cause loss of
control and an extremely dangerous situation may occur. It may also
cause amp trouble. Should moisture enter and cause erroneous
operation, send the MC950CR out for repair and inspection.
Always turn the power switches on and off in the following order:
ON: Transmitter -> receiver (amp switch)
OFF: Receiver (amp switch) -> transmitter
If the power switches are operated in the opposite order, the vehicle
may run unexpectedly and an extremely dangerous situation may
occur.
When going to and returning from the circuit, and when
storing the model, always remove the Nicd battery.
If the switch is turned on erroneously, control may be lost or a fire may
start.
Always perform a check of operation before running.
When making adjustments, remove the motor, or place the
vehicle on a stand, so that it cannot run.
When not set up correctly, the vehicle may run unexpectedly and an
extremely dangerous situation may occur.
INSTALLATION TIPS
• Mount the speed control in the model using the double-sided foam tape supplied.
• Provide plenty of cooling openings in the bodywork; this increases the performance and extends the life of all
electronic components.
• Install the speed control in a location where it is protected from crash damage.
• The speed control should be installed in such a way that you have easy access to all connectors and the set-up button.
Important:
•Ensure that there is an adequate distance (approx. 3 cm) between the speed control and power cables and the receiver or receiver antenna. Avoid
direct contact between all power system components and the receiver or antenna, as this can cause interference. If you encounter interference
problems, re-position the components in the model.
•The antenna should be run vertically up and away from the receiver. Avoid contact with any parts made of carbon fibre or metal. See also the
instructions supplied with your radio control system.
Do not wrap your MC950CR in foil.
It is important to provide a free flow of cooling air over it.
Do not remove the case of MC950CR.
The MC950CR may not be repairable.
Never reverse the battery polarity.
Reverse connection will immediately destroy the amp.
Mount the MC950CR so that conductive parts do not directly
touch the solder parts of the input/output cord.
A short circuit may occur.
If a peddle or other foreign object gets caught in the gears
or the vehicle hits an obstruction, do not try to forcefully run
vehicle.
Forcefully running the vehicle will cause trouble.
Do not touch the motor or MC950CR immediately after
running.
Touching the motor or amp immediately after running may result in
serious burns.
If the motor is connected to the speed control, you must not
run the motor by connecting a separate battery.
This will wreck the unit.
Turn the power switches on in the state where the vehicle is
floated.
When turnning on, depending on the receiver used, a motor may rotate
for a moment. Be careful not to injure a finger etc. by rotation of the
wheels.
