2. Connections & Explanations
Receiver & Switch Connecting
Wires: The iX8 V2 is equipped with
pluggable LRP Multicon receiver
wire + pluggable switch wire. As
supplied, it will easily fit in all ordi-
nary receivers. Make sure you con-
nect the receiver wire with correct
polarity and use channel 2.
Sensor Connector: The bi-directio-
nal multipole sensor wire connects
the speed-control and the motor.
Always use the sensor wire and do
not alter or modify this cable! There
are replaceable/optional hall sensor
wires available.
Through this sensor connector, the
speedo can also be updated with the
latest software updates using the optional „USB Bridge #81801“. Please refer to chapter „USB Soft-
ware Updatability“ for details
Power Wires: For maximum convenience and performance, the flexible silicone power wires are a
plug-in design using high-power 4.0mm power sockets & connectors. There are replacement power
wires available, please refer to complete line-up at www.LRP.cc.
Note: In high temperature and high load conditions we recommend to cut the 4mm plugs and solder
motor cables directly to the motor. You should always check all connections that the connector plugs
are tightly placed in power sockets. This protects your speedo from shutdowns and defects!
Heatsink: To achieve best perfomance even under extreme conditions, the heatsink is an integral part
of the design and directly connected to the FETs. This ensures the best possible heat transfer away
from the speed-control.
Plugged Cooling Fan: The iX8 V2 comes with a high-performance low-profile (30x30x6mm) fan,
protection cover and mounting screws. The fan can be mounted on top of the heatsink and should
be used for tough applications in hot conditions. It gets plugged into the 3-pin connector on the front.
3. Installation Guide
• Position the speed-control where it is protected in the event of a crash and gives you easy access
to the connectors and buttons.
• Mount the speedo using the supplied thick/black doubled-sided tape.
• Make sure there is enough clearance between the speed-control, power-wires, antenna and
receiver. Avoid any direct contact between power components, the receiver or the antenna as 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. See also the
instructions supplied with your radio control system.
The iX8 V2 comes supplied with flexible 3.3mm² silicone power-wires and attached 4.0mm bullet
connectors. Be very careful with the correct wire sequence/colors since an incorrect connection may
damage the speed-control! Avoid creating solder bridges on the solder-tabs and isolate all connec-
tions carefully.
• Connect the speed-control to the receiver (position: Channel 2)
• Blue power-wire Speedo MOT.A to motor „A“
• Yellow power-wire Speedo MOT.B to motor „B“
• Orange power-wire Speedo MOT.C to motor „C“
• Connect the hall sensor cable to the speed-control and the motor.
• 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 Speedo BAT+ to battery „Plus“
• Black power-wire Speedo BAT- to battery „Minus“
Your speed-control is now ready to be set-up.
4. Calibrate Speed-Control to Radio
In setup mode the speed-control stores every step (e.g. learning your radios neutral and endpoints)
by pressing the SET button. All the settings will be stored in the memory even if it will be discon-
nected from the battery.
• This completes the setup procedure and your iX8 V2 is ready to use.
• If you make a mistake during the setup procedure, don‘t worry: Disconnect the battery for about
10sec and start again from the first step.
• At the start of each run switch on the transmitter first, then switch on the car.
• At the end of each run switch off the car, and then switch off the transmitter.
• For storage of the car, disconnect the drive battery at any time!
Check the LEDs when moving the throttle on your radio to doublecheck everything is setup correctly.
5. Multi Protection System 3
New and improved protection system „MPS3“ which also tells you the cause of the shutdown
with a special LED flashing sequence. You can indicate that a shutdown occured when blue SET
LED flashes very fast and the „error code“ (= cause for shutdown) is indicated by the MODE LEDs
as explained in the table below.
Error Code LED flashing sequences:
Error
Code
Set
LED
Mode
LEDs
Reason Possible Cause
#1
Blue
(fast
flashing)
Yellow Speed-Control Thermal Shutdown
1. too strong motor or too high battery voltage for application
2. insufficient cooling of speed-control or motor.
3. too high gear ratio?
#2 Red Motor Thermal Shutdown
#3
Yellow/Red
(alternate)
Battery Low Voltage Cut-Off
1. battery empty?
2. battery empty or weak?
3. motor too strong for battery discharge capability?
4. poor connection (bad connector, bad soldering joint)?
#4
Yellow/Red
(same time)
Motor Failure
1. sensor wire missing or defective?
2. drivetrain stuck?
3. motor defective (locked rotor, damaged sensor)?
Internal-Temp-Check System 3: Allows you to read-out the maximum internal temperature that
the speedo and motor have reached during the run. You can conveniently read-out the tempera-
ture back in the pits since it remains stored until you turn it on the next time regularly (which will
reset the memory). This feature allows you to accurately check if all is running well or if you‘re
close to shutdown already.
How to read-out the temperature:
Switch at „OFF“ position.
Keep MODE button pressed while you turn switch to „ON“ (then release button).
At first speed-control temperature will be indicated.
SET LED will start to flash blue (MODE LEDs are off) ....
Count the number of flashes.The higher the number, the hotter the speedo ran (shutdown
occurs at 10 flashes).
To change to motor temperature read-out, press MODE button one more time.
SET LED will start to flash blue (MODE LEDs are off) again, for motor the LEDs on time will be
shorter.
Count the number of flashes.The higher the number, the hotter the motor ran (shutdown
occurs at 10 flashes).
Every flash below 10 equals to 5°C temperature decrease.
Temperature chart (speed-control and motor temperature):
CAUTION: motor temperature read-out only works if your motor has a built-in NTC temperature
sensor!

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.
