3. SPECIFICATIONS
•
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
, antenna
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.

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 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.
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.

Smart-Temp-Readout
-
System:
A
s a world-exclusive the NOSRAM MATRIX EVOLUTION ISTC
allows
you to read-out the maximum
internal
temperature that the speedo reached. To save it to the memory you
have to briefly apply brakes after the run before you turn the switch off. 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 new 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:

Swit
ch
at
„OFF“ position.

Keep MODE button pressed while you turn swit
ch to „ON“ (then release button)


9. WARNING NOTES
No toy. Not suitable for children under 14 years.
Keep the product out of the reach of children.
Pay close attention to the following points, as they can de-
stroy the product and void your warranty. Non-observance
of these points can lead to property damage, personal and
severe injuries!
•
Never leave the product unsupervised while it is switched on,
in use or connected with a power source. If a defect occurs,
it could set fire to the product or the surroundings.
•
Never wrap your product in plastic film, metal foil or similar.
In fact, make sure it gets enough fresh air.
•
Avoid incorrect connections or connections with reversed
polarity of the product.
•
All wires and connections have to be well insulated. Short-
circuits can possibly destroy the product.
•
Never allow this product or other electronic components to
come in contact with water, oil or fuels or other electrocon-
ductive liquids, as these could contain minerals, which are
harmful for electronic circuits. If this happens, stop the use
of your product immediately and let it dry carefully.
•
Never cut off or modify the original plugs and original wires.
•
Never open the product and never solder on the PCB or other
components.
•
Never use this product when the case is open, damaged or
missing or when the product is wrapped in a shrink-fit tube.
This will reduce protection, may cause short circuits and da-
mage the product.
•
Always remove the battery from your product or disconnect
REPAIR PROCEDURES / LIMITED WARRANTY
the product from the power source, if the product is not in use.
Always remove the battery from your product or disconnect
the product from the power source, if the product is not in use.
Always remove the battery from your product or disconnect
•
Always switch on your transmitter first before you switch on the receiver or the speed control. The
receiver could receive interference signals, start full acceleration and damage your model. When you
switch off, make sure you do so in the reverse sequence. First switch off the receiver and speed control,
then switch off the transmitter.
•
Never solder a Schottky diode to the motor when you are using this speed-control.
•
If the speed-control is connected to the motor, never run the motor directly with a separate battery or
run-in device.
•
Never change the polarity of the receiver connector.
•
Always wire up all the parts of the equipment carefully. If any of the connections come loose as a result
of vibration, you could loose control over your model.
•
Avoid soldering longer then 5 seconds per soldering joint when replacing the power wires to prevent pos-
sible damage to the product due to overheating of the components. Use a high power soldering station
for soldering.
•
Never apply full throttle if the motor is not installed. Due to the extremely high RPMs without load, the
motor can get damaged.
