4. SPECIFICATION
•
Mount
the speed
o
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.
H
ALL 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. B
RUSHLESS (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. B
RUSHLESS (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 s
kills are still required.
However plea
se note, that
your warranty may void if you cut-off the
plugs
.
Therefore we recommend using the original power-
wires and plugs.

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 tr
ansfer away from the speed-
control.
Caution
:
Never attempt to remove the he
atsink.
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).

8. AUTOCELL SYSTEM
The L
RP A.I. BRUSHLESS (PRO) REVERSE speed-control features LRPs excluxive AutoCell System. You
can choose between 2 modes:
•
LiPo/NiMH
-Automatic Mode
•
4-7cell NiMH Racing Mode
The wo
rks default setting
of the speed-contro
l is
LiPo/NiMH
-Automatic mode.
When using the LiPo/NiMH-Automatic Mode, the speed-control will switch off the drive function as
soon as the battery voltage falls under a value, which is harmful for LiPo batteries. Thus protecting your
LiPo battery against deep-discharging. If you are using your speedo with LiPo batteries, we strongly
recommend to always use the LiPo/NiMH-Automatic Mode. When using the 4-7cell Racing Mode, the
drive function will not be switched off.
Displaying the current mode during switch-on:
You can check the current
mode setting by
switching on the speed-control while the transmitter is also
switched on. The
initial flashing of the LED
tells you, which mode is currently activated.
• The LED flashes
once
, followed by a short break and then stays on continuously.

LiPo/NiMH-Automatic Mode is active.
•
The LED flashes
twice
, followed by a short break and then stays on continuously.

4-7cell NiMH Racing Mode is active.
Toggle AutoCell mode:
1. Pull out the receiver wire from the receiver
.
2. Turn on the speed-control
(with the battery connected)
.
3. The LED flashes and indicates the current mode.
See above for further reference.
4. After approx. 5 sec, the speed-control automatically switches the mode. This will be indicated by the
LED flashing again and indicating the new mode.
5. Turn off the speed-control. The new mode setting is now stored.
6. Re-c
onnect the receiver wire of the speed-control with the receiver.
7. SPECIAL FEATURES
A
utomatic Br
ushless / Brushed Adaptation:
The LRP exclusive Automatic Brushless/
Brushed Adapt
at
ion
detects the connected motor type
during
turn-on
/
initialisation
and adjusts the
correct brushless or brushed
operation
automatically
.
No
adjustment
s
required by yourself, apart from
the correct connection of each motor type (don‘t forget the hall-sensor-wire for brushless!).
LRP A.I. Automatic:
Due to the LRP exclusive A.I. Automatic Technology, there is no need for a
manual setup of the speed-control by pushbuttons or potentiometers. All you need to do is simply plug
in the speed-control and you’re re
ady to go. The speed-control “learns” the neutral, full-speed forward
and full-speed reverse point of the radio system while the car is running. This way, the speed-control
has the optimized setup for every run - automaticly. Incorrect setups are a thing of the past with the
LRP
A.I. B
RUSHLESS (PRO) REVERSE
speed-controls.
AutoCe
ll S
ystem:
Ready
for th
e next battery technology – LiPo batteries! LRP’s exclusive and
smart AutoCell System ensures that LiPo batteries can be used safely without
accidentially
deep-di-
scharging
of
the cells.
T
he motor function will be shut-off and the LED will flash
if
the system recognises
very low battery voltage
.
Waterproof:
Due to latest production technologies and use of HighTech materials, it was possib-
le to make these speed-controls fully waterproof! This material also makes the speed-controls more
shock resistant then other similar products.
It‘s no longer needed to seal your speed-control when you
are driving in the rain/snow!
But
please make sure you still seal your other electronic components (receiver, servo and motor) since
these are normally
not waterproof
and will
get damaged due to the water.
Fail Safe System:
Digital protection against radio interference, “The guardian angel“. The safety
electronic can detect reception of a “false” or incomplete radio signal, e.g due to a low transmitter
battery or environmental radio interference which reach the model, or if the model is out of the trans-
mitter range. For protection against damage, the speed-control switches to the neutral position, and
the model comes to a stop.
LRP tip:
The model will remain in a standstill, even if you connect the drive battery to the speed-control
first and then switch on the transmitter! Provides perfect protection against mistakes commonly made
by beginners.
Sensored Brushless Technology:
The sensors allow the perfect knowledge of the brushless
motor’s magnet position. This
results in
perfect motor control at high and low RPM‘s, as well as perfect
brake control.
Mu
lti-Protection System, 3-way protection:
T
he perfect protection against short-cir-
cuits (motor), overload and overheating (of the speed-control and of the motor). If your speed-control or
motor faces overload, the motor function will be shut-off for protection and the LED will flash, although
the steering function is maintained. Let everything cool down for a few minutes.
If the speed-control switches off frequently, either the motor used is too strong, the motor pinion is
too big or you are using full brake too often. You can improve this if you make additional cooling slots
in the body.
After wiring up the speed-control, it is ready to operate. No setup is required. The speed-control
„learns“ the neutral, full-speed forward and full-speed reverse points while the car is running.
Please note:
Before you plug in the drive battery, set the transmitter to neutral position and then start
the model in the forward direction.
CONNECT THE SPEED-CONTROL TO TH
E BATTERY
SWITCH ON THE TRANSMITTER
AND... GO!
• 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..
