• First attach the heat-sinks (supplied) to the speed control, as described under “Installation tips”.
• Solder the suppressor capacitors to the motor.
• Remove the motor pinion, or ensure in some other way that the wheels of the model can rotate freely.
The Schottky diode improves the efficiency of the speed control / motor combination and provides extra
protection to the brake FETs. Solder the diode in place as shown in the illustration. The white ring must
always face the positive motor terminal.
Bend the metal lugs up again. Push the plug
into the new plastic moulding.

Check correct polarity carefully if changing connectors:
MOTOR SUPPRESSION:
• Install the speed control in the model.
• Connect the speed control to the receiver (channel 2).
• Check that the switch is set to “OFF”.
• Connect the speed control to the motor. Note the colour code: yellow wire positive, blue
wire negative.
• If you are using a servo with an external FET lead, solder this in place (Quantum Pro-Sport only).
• Check all the wiring and connections before you connect the speed control to a drive battery.
Caution: incorrect polarity will wreck your speed control.
• The speed control is now ready to be set-up (see back page).

• 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.
• Ensure that there is an adequate distance (approx. 3 cm) between the speed control 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, re-position 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 fibre or metal. If the aerial is too long, don’t coil up the excess length. It is better to
cut it down to a length of about 35 cm. See also the instructions supplied with your radio control
system.
•
Graupner, Ko-Propo, Futaba, Hitec and LRP Phaser receivers:
The LRP speed control is fitted with an LRP Multi-Con receiver lead which fits any of the above
receivers directly.
•
Sanwa receivers:
Remove the black plastic moulding from the receiver cable and replace it with the plastic moulding
supplied (inscribed “
AIR
”) as follows:
•
Replacing the plastic plug moulding
:
Press in the metal lugs of the connector pins using a ball-point pen to disengage them; the wires
can then be withdrawn from the plastic housing. Check the polarity using the table below, and slip
the pins into the new plastic moulding until they snap into place.

Important
: never leave your RC model unattended when the
battery is connected. If a fault should occur the result might be a
fire in the model which could destroy anything else in the vicinity.
• The speed control and other electronic components must
never
be allowed to contact water.
Avoid operating the unit in rain.
If you are obliged to run in wet conditions, domestic paper towels
provide the best protection.
• 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 and invalidate the guarantee.
• Do not cut off the original plug, as this invalidates the guarantee.
• Take care to avoid incorrect connections and reverse polarity as
this will also cause damage to the unit. If you prefer different
connectors, fit a polarised connector system (plugs / sockets)
such as the LRP Hi-Amp (No. 6280); this does not invalidate your
guarantee.
• Never allow the output stages (FETs) to contact any metal object
- short-circuit hazard.
• Do not wrap your speed controller in foil; it is important to
provide a free flow of cooling air over it.
• All cables and connections should be well insulated; short
circuits can easily wreck the controller.
• Never alter the polarity of the receiver plug.
• If you use
more than 6 cells
in the drive battery, the motor limit
rises by 2 turns for each additional cell.
