POWER CAPACITOR
Always install Power Capacitor to suppress battery noise.
Also, Power Capacitor stores battery energy and supplies
this to the motor additionally when extra power is
required.
[INSTALLATION]
See the pictures for the example of installation.
1
Remove the terminal cover from the MC950CR.
2
Use the included heat shrink tube to isolate the pins of the
Power Capacitor. This will also make it easier to indicate the
polarity of the Power Capacitor. Place the red heat shrink tube
on the positive terminal and the black heat shrink tube on the
negative terminal.
3
The Power Capacitor needs to be soldered to the speed control
b (positive = M.B.+ ) and - (negative = BAT.-).
4
Attach the terminal cover to the MC950CR.
[Wiring Precautions]
• Always set the MC950CR power switch to the OFF position
before performing any wiring.
• When stripping the covering of the silicon cord to the length
needed for soldering, be sure not to cut the center conductor with
the cutter or nippers.
• Refer to the diagram above and check the polarity before
performing wiring.
• When soldering to the terminals of the MC950CR, remove the
terminal cover. (After soldering, re-install the terminal cover.)
Heat shrink tube
(positive = red / negative = black)
Never reverse the capacitor and wires polarity.
The capacitor may break or the capacitor electrolyte may leak.
Reverse connection will immediately destroy the amp.
Never use solder containing acid flux.
Use solder containing rosin flux only. Do not inhale the solder
vapours. This might damage health.
Vibrationproof the capacitor by mounting it with thick
double sided tape.
If the pin of the capacitor is broken, it may short-circuit with the pin
b and - terminal of the speed control.
Be careful when soldering to the tags on the speed control;
don’t overheat the tags with your soldering iron and take
great care to avoid short-circuits between two of the three
tags on the speed control.
Such a short-circuit would destroy the speed control.

In set-up mode MC950CR stores every step when you press the Set-up button. All the settings are stored in the unit even when the
speed control is subsequently disconnected from the battery. Set up the following basic functions on your transmitter (if present):
• High ATV, EPA (throttle travel) - maximum Low ATV, EPA, ATL (brake travel) - maximum
• EXP, EXPO (exponential) - start with 0
• SUB trim (neutral trim) - center TH trim - center
• Throttle reverse (servo reverse) - any setting; must not be changed after completion of set-up procedure.
• Non-proportional stick travel is possible (2/3 throttle - 1/3 brake)
If your transmitter does not feature these set-up functions, it is already in “basic set-up” mode.
Remove the motor pinion, or ensure in some other way that the wheels of the model are free to rotate.
• The SET LED flashes green, to indicate that the unit is in set-up mode.
• This completes the set-up procedure.
Hold the SET button pressed in for at least 3 seconds using the small screwdriver supplied.

procedure, and setting is not completed.:
switch MC950CR off and start again from

the CHECKER LED DISPLAY are not
correct, set up again from the first step.

Protection Circuits
Heat protection:
After the FET overheating is detected, a protection circuit operation alarm is activated, and the output to the motor
is gradually lowered, and then, output to the motor is cut. The protection circuit is automatically reset by a drop in the FET
temperature.
Low battery protection:
When the power supply voltage drops, the output current to the motor is limited and supply voltage to the
receiver is ensured. When the power supply voltage drops to the set voltage (initial setting 2.7V), a protection circuit operation alarm
is activated and output to the motor is cut. The protection circuit is automatically reset by recovery of the power supply voltage.
Reverse Cancelling function (Brake operation only)

*When desired, you can enable the cancelled reverse function by repeating the operation shown above. (The reverse function is switched alternately.)

• The MC950CR operating state can be checked with the LED as shown below.
• After operating the throttle trigger (stick) of a transmitter to the brake (reverse) side, if it is again operated to the brake side
once it returns to a neutral position, MC950CR will carry out reverse operation.
