USER MANU
• Position the speed-control and capacitor where they are protected in the event of a crash and gives you easy
access to the connectors and buttons.
• Mount the speedo and capacitor 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.
• 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.
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 the speed-control will get damaged if you do this. The
heatsink is an integral part of the speed-control and therefore cannot be removed.
RECEIVER CONNECTING WIRE: The SPX8 is
equipped with an LRP Multicon receiver wire. As
supplied, it will easily fit in all ordinary receivers.
Make sure you connect it to receiver with correct
polarity and use channel 2.
SENSOR CONNECTOR: The bi-directional mul-
tipole sensor wire connects the speed-control
and the motor. Always use the sensor wire and
do not alter or modify this cable! There are repla-
ceable/optional hall sensor wires available, please
refer to complete line-up under point 6 „Spare- &
Optional-Parts“.
POWER WIRES: For maximum performance,
flexible silicone power wires without any con-
nectors are used. The unique splitted solder-tabs
allow easy and convenient replacement of the
power wires. Nevertheless some soldering skills
are required. Avoid soldering longer then 5sec per
soldering joint to prevent possible damage to the
speed-control due to overheating of the compon-
ents! There are full replacement power wire sets
available, please refer to complete line-up under
point 8 „Spare- and Optional Parts“.

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.
In setup mode the SPX8 stores every step (e.g. learning your radios neutral and endpoints) when you press the SET
button. All the settings will be stored in the SPX8‘s memory even if it will be disconnected from the battery.

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.
 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 SPX8 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 end of each run switch off the car, and then switch off the transmitter.
• At the start of each run switch on the transmitter first, then switch on the car.
• For storage of the car, disconnect the drive battery at any time!
FUNCTION STATUS MODE LED SET LED
Neutral (automatic brake inactive) -- off blue
Neutral (automatic brake active) -- red off
Forward partial throttle yellow off
Forward full throttle yellow blue
Brake partial brake red off
Brake full brake red blue
CHECKING THE FUNCTIONS:
Check the LED‘s when moving your throttle stick and you will see if everything is setup correctly.

As a unique feature the SPX8 comes supplied with an external BEC input wire (thin black wire, we call it „BEC
Input“) which you need to attach to 7.2-7.4V on your battery pack(s). There are several ways to do that:
1. if you use a single 7.2 or 7.4V pack  attach „BEC Input“ straight to Bat+ solder tab
2. if you use dual 7.4V packs (2 LiPo‘s)  attach „BEC Input“ to connecting bridge between the two packs!
3. if you use a single 3S or 4S LiPo pack

attach „BEC Input“ to correct pin of balancing connector of your
3S or 4S LiPo pack (check specs of pack about which pin that is!).
CAUTION: be careful with correct connection of „BEC Input“ wire as wrong connection (wrong position or too high
input voltage) may either overheat or damage the BEC and/or speed-control!
BEC 7.4V Input Wire
BEC 7.4V INPUT WIRE: this unique wire, which exits from the switch, must be connected to 7.4V input. Please
refer to full details in chapter „3. BEC Connection“ for correct installation.
