Receiver & Switch Connecting Wires: The iX8 is equipped with pluggable LRP Multicon receiver wire + plug-
gable switch wire. As supplied, it will easily fit in all ordinary receivers. Make sure you connect the receiver wire
with correct polarity and use channel 2.
Sensor Connector: The bi-directional 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 iX8 can also be updated with the latest software updates using the optional
„USB Bridge #81800". Please refer to chapter „USB Software Updateability" for details
Power Wires: For maximum convience 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.
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 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 get's plugged into the 3-pin connector on the front.

Installation Guide

• Position the speed-control where is protected in the event of a crash and gives you easy access to the connec-
tors 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 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 connections 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.

Thank you for your trust in this LRP product. By purchasing a LRP iX8 brushless speed-control, you have chosen
one of the most advanced and successful speed-controls of today. This speed-control with all of its high-tech
features and specially selected electronic components is one of the best speed-controls currently available on
the market.
• Pure Brushless Competition
• 2S to 6S operation
• 6.0V / 6.0A Switching BEC
• Internal-Temp-Check System 3
Please read the following instructions carefully before you start using your speed control. This user guide contains
important notes for the safety, the use and the maintenance of this product. Thus protecting yourself and avoid damages
of the product.
Proceed according to the user guide in order to understand your speed control better. Please take your time as you will
have much more joy with your product if you know it exactly.
This user manual shall be kept in a safe place. If another customer is using this product, this manual has to be handed
out together with it.

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 disconnected from the battery.
TRANSMITTER SETTINGS: Setup the following basic functions on your transmitter (if available):
Throttle Travel High ATV, EPA
Brake Travel Low ATV, EPA, ATL
Throttle Exponential EXP, EXPO
Neutral Trim SUB Trim
Servo Reverse Throttle Reverse
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.
 You entered setup mode and the SET LED flashes blue (it will flash until the setup is completed).
• Leave transmitter in neutral position and press the SET button once.
 Neutral setting is stored , MODE LED flashes yellow and the motor beeps.
• Hold full throttle on transmitter and press the SET button once.
 Full-throttle setting is stored, MODE LED flashes red.
• Hold full brake on transmitter and press the SET button once.
 Brake setting is stored, LED's glow red (MODE) and blue (SET).
• This completes the setup procedure and your iX8 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 of the car, and then switch off the transmitter.
• For storage of the car, disconnect the drive battery at any time!
Check the LED's when moving the throttle on your radio to doublecheck everything is setup correctly.

Multi Protection System 3

New and improved protection system „MPS3" which also informs 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 LED's as explained in table below.
Error Code LED flashing sequences:
Error Set Mode
Reason
Code LED LED's
#1
Yellow Speed-Control Thermal Shutdown 1. too strong motor or too high battery voltage for application
#2
Red Motor Thermal Shutdown

Active Fan Operation:
the fan will only become active above a certain temperature level of the speed-control,
at initialisation (turn on of the speed-control with radio switched on) the fan will run for 3sec to indicate it's correct
operation.
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 convienently read-out the temperature 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 LED's 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 LED's are off) again, for motor the LED's 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):
#1 #2 #3 #4 #5 #6
> -45°C -40°C -35°C -30°C -25°C -20°C
> -81°F -72°F -63°F -54°F -45°F -36°F
Caution: motor temperature read-out only works if your motor has a built-in NTC temperature sensor!
USB Software Updateability
Through the sensor connector the iX8 can be updated to the latest firmware available for download at www.LRP.cc.
The optional „USB Bridge - Speedo Firmware Update + PC-Link" (#81800) and a Windows-PC or MAC are required
to do so, please refer to LRP website and the manual which comes with the interface for exact details how to do
software updates to your speed-control.
The same USB-Bridge can be used to update all the latest LRP speed-controls (80230, 80250, 80905, 80915,
80955, etc). Please check guide at ww.LRP.cc for further details.
