4. SPECIFICATION
• Mount the speedo 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.
2. INSTALLATION TIPS
1. CONNECTIONS
RECEIVER CONNECTING WIRE:
This LRP speed-control is equipped with an LRP Multicon receiver wire. As supplied, it will easily fit in
all ordinary receivers.
HALL SENSOR WIRE:
This bi-directional multipole wire (which comes with the motor and NOT the speed-control!) connects
the speed-control and the motor. Do not alter or modify this cable! There are replaceable/optional hall
sensor wires available: • #81910 (20cm)
• #81920 (10cm)
POWER WIRES:
The LRP A.I. BRUSHLESS (PRO) REVERSE speed-control comes pre-wired using common „Tamiya-/JST
style“ battery and motor connectors. Together with a LRP ERASER BRUSHLESS SPORTS MODIFIED
motor (#50350-50380) and a pre-assembeled battery-pack from LRPs selection of battery packs, the
speed-control can be used instantly without the need of a solder iron. Additionally included with this
speed-control are a set of adapter wires, to connect the LRP A.I. BRUSHLESS (PRO) REVERSE with a
brushed motor (please see section 5 „Installation“ for further reference).
You can also solder the power wires of the speed-control directly to the motor, if you do not want to
use the supplied plugs. Nevertheless some soldering skills are still required. However please note, that
your warranty may void if you cut-off the plugs. Therefore we recommend using the original power-
wires and plugs.
5. INSTALLATION
USER MANUAL
CONNECTION OF A BRUSHED MOTOR:
• Blue/Yellow power-wire
Connect to motor „Minus“
• Orange power-wire
Connect to motor „Plus“
LRP Tip:
Use the supplied adapter wires.
CONNECTION OF A BRUSHLESS MOTOR:
• Blue power-wire
Connect to motor „A“
• Yellow power-wire
Connect to motor „B“
• Orange power-wire
Connect to motor „C“
• Connect the hall sensor cable to the speed-control and the motor.
HEATSINK:
To achieve best perfomance even under extreme conditions, the heatsink has been directly
mounted to the speed-control. This ensures the best possible heat transfer away from the speed-
control.
Caution:
Never attempt to remove the heatsink.
Because of the physical principles of brushless technology, the speed-controls do get a little hotter
then brushed systems. Therefore it is required to let the speed-control cool down completely after
every run. When running in extreme conditions (high ambient temperature, low-turn motors, high gear
ratios, etc.) we recommend using LRP‘s brushless cooling set #82500, which includes an optional fan
(perfectly sized 25x25mm, pre-wired).

Set-Up Procedure

The LRP A.I. BRUSHLESS (PRO) REVERSE speed-control comes pre-wired using common „Tamiya-/JST
style“ battery and motor connectors. Be very careful with the correct wire sequence/colors since an
incorrect connection may damage the speed-control!
• Mount the speedo using the supplied thick/black doubled-sided tape.
• Connect the Receiver wire of the speed-control with the receiver (position: Channel 2).
Caution:
Be careful with the correct polarity of the receiver wire!
• Doublecheck all connections before connecting the speed-control to a battery.
CAUTION:
If battery is connected with reversed polarity it will destroy your speed-control!
• Red power-wire
Connect to battery „Plus“
• Black power-wire
Connect to battery „Minus“
• 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 „Speed-Control Set-up“ for
further reference).
3. SUPPRESSION
ONLY FOR BRUSHED MOTORS!
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).
Brushless motors do not require an additional
suppression.
CAUTION:
Never use Schottky diodes in
conjunction with a brushless or forward/re-
verse brushed speed-control, e.g. the LRP A.I.
BRUSHLESS (PRO) REVERSE.
