[MC850C Technical Data] (Specifications are subject to change without prior notice.)
MOUNTING PRECAUTIONS
Accessories
• Schottky diode (for motor)
• Capacitors (for motor)
• Double sided tape
• Silicone flex wire (Red,Black,Blue)
• Heatshrink tube, red (x1), black (x1)
• Miniature screwdriver
(Use to press the pushbutton switch.)
Important:
Because the MC850C 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 MC850C 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.
Always install a motor noise suppresser capacitor. Also, do
not forget to service the brushes, and other parts.
If noise causes the receiver to operate erroneously, control may be lost
and an extremely dangerous situation may occur
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 MC850C 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.

Before using your MC850C, please read this manual thoroughly
and use the MC850C properly and safely. After reading this
manual, store it in a safe place.

Thank you for purchasing an MC850C . The MC850C 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 MC850C with a motor with 5 turns or more.
*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.
Power supply

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 lectronic
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.
• Operating system: Forward and brake (resolution:255)
• Power requirement: Nicd, NiMH battery 4~7 cells (4.8~8.4V)
• PWM frequency:
Forward：100Hz∼10kHz／Initial value：2.5kHz∼3.0kHz
Brake：2.0kHz
• BEC voltage: 6.0V (excluding at less than 6V)
• Setting: One-touch input by pushbutton switch.
• Current capacity (FET rating) :
Forward ：840A (Momentary load: 3360A)
Brake ：240A
• Case size: 28.7x26.2x14.5mm (excluding protruding parts)
• Silicon cord gauge size: AWG12 equivalent
• Weight: 17.5g (excluding connector, cords and switch)
Do not wrap your MC850C in foil.
It is important to provide a free flow of cooling air over it.
Do not remove the case of
MC850C
.
The MC850C may not be repairable.
Never reverse the battery polarity.
Reverse connection will immediately destroy the amp.
Mount the
MC850C
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 MC850C 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 un
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.
