RECEIVER CONNECTING WIRE:
This LRP speed-control is equipped with a LRP Multicon receiver wire. As supplied, it will easily fit in
all ordinary receivers.
POWER WIRES:
For maximum performance, 13AWG power wires without any connectors are used. The motor power
wires can be soldered directly to the motor. For the battery power wires we recommend to use reverse
polarity protected plugs. Nevertheless some soldering skills are required. Avoid soldering longer then
5sec per soldering joint to prevent possible damage due to overheating! (Please see section 5 „Instal-
lation“ for further reference)

4. SUPPRESSION
Motors with no capacitors or not enough
capacitors may interfere with the speed-
control. To avoid this, solder the supplied
capacitors to your motor (see picture).
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.

For maximum performance, 13AWG power wires without any connectors are used for your LRP IPC
V8.1 GEN speed-control. The motor power wires can be soldered directly to the motor. For
the battery power wires we recommend to use reverse polarity protected plugs.
• Mount the speedo using the supplied thick/black doubled-sided tape.
• Connect the receiver connecting wire of the speed-control with the receiver (position: Channel 2).
• Connect the speed-control to the motor:
Red wire
Connect to motor „Plus“
Blue wire
Connect to motor „Minus“
CAUTION:
Be careful with the correct polarity!
• Solder some suitable plugs to the battery power wires (please also see section 2 „Connections“ for
further reference). The plugs are not included with the speed-control. We recommend to use some
reverse polarity protected plugs.
Red wire
Connect to battery „Plus“
Black wire
Connect to battery „Minus“
• Doublecheck all connections before connecting the speed-control to a battery.
CAUTION:
If a battery is connected with reversed polarity it will destroy your speed-control!
• You can now switch on the speed-control with the On/Off switch.
• The speed-control is now ready to be set-up (please see section 6 „Radio/speed-control set-up“ for
further reference).
Note:
If your servo has an external FET connection, you have to connect it to the blue FET servo wire
of the speed-control.

• Mount the speed-control using the supplied thick/black doubled-sided tape.
• Position the speed-control where it is protected in the event of a crash.
• Install the speed-control so that you have easy access to the connector and buttons.
• Make sure there is enough clearance (about 3cm) between the speed-control, power-wires, anten-
na and receiver. Avoid any direct contact between power components, the receiver or the antenna.
This can cause interference. If interference occurs, position the components at a different place 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.
• Make sure there are enough cooling slits in the body. This will increase the performance and life of
all the electronic components.
HEATSINK:
The supplied heatsink is not mandatory. But it improves and safeguards the performance capacity of
your LRP IPC V8.1 GEN speed-control when used close to it‘s specified limits.
Use only the genuine LRP IPC V8.1 GEN heatsink. Never allow the forward FETs or their
heatsink to touch the brake FET or its heatsink. This will result in a short circuit!

TRANSMITTER SETTINGS
Setup the following basic functions on your transmitter (if available):
If your transmitter doesn‘t offer any of above functions, it‘s already in „basic setup“ mode.
• Ensure that the speed-control is not connected to the drive battery and is switched off.
• Remove motor pinion or ensure that the wheels of the model are free to rotate.
• Switch the transmitter on and set the transmitter throttle stick to neutral.
• Connect the speed-control to the battery and switch the unit on.
• Hold the SET button pressed for at least 3sec using the supplied plastic screwdriver.
You entered setup mode and the lower SET-LED flashes red (it will flash until the setup is comple-
ted).
• Leave transmitter in neutral position and press the SET button once.
Neutral setting is stored , the upper Brake-LED flashes green and the motor beeps.
• Hold full throttle on transmitter and press the SET button once.
Full-throttle setting is stored, the upper Brake-LED flashes red.
• Hold full brake on transmitter and press the SET button once.
Brake setting is stored, the upper Brake-LED and the lower SET-LED glow red.
• This completes the setup procedure and your LRP IPC V8.1 GEN speed-control is ready
to use.
• If you have made a mistake so far, don’t worry: Switch off the speed-control for about 10 seconds
and start over again.
• After the run, first switch off the speed-control, unplug the battery and then switch off the transmit-
ter. When you start again, first switch on the transmitter, then plug in the battery and switch on the
speed-control.
• Always disconnect the drive battery from the speed-control, if you are not using your model.
CHECKING THE FUNCTIONS:
Check the LED when moving your throttle stick and you will see if everything is setup correctly.
In setup mode, the LRP IPC V8.1 GEN speed-control stores every step when you press the
SET button. All the settings will be stored in the speed-controls memory even if the speed-control will
be disconnected from the battery.
