2. CONNECTIONS
RECEIVER CONNECTING WIRE:
This speed-control is equipped with an NOSRAM Multicon re ceiver wire. As supplied, it will easily fit in all ordinary
receivers.
HALL SENSOR WIRE:
This bi-directional multipole wire connects the speed-control and the motor. Do not alter or modify this cable!
There are replaceable/optional hall sensor wires available: • #92510 (20cm) • #92520 (10cm)
POWER WIRE:
For maximum performance, 2.6mm² power wires without any connectors 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 components! There is a full 2.6mm² replacement power wire set available: #92505
Caution: Be very careful with the correct wire sequence since an incorrect connection may damage the speed-
control! Avoid creating solder bridges on the solder-tabs and isolate all connections carefully. Avoid soldering
longer then 5sec per soldering joint.
5. SUPPRESSION
ONLY FOR BRUSHED MOTORS!
Motors with no capacitors or not enough capaci-
tors may interfere with the speed-control. To avoid
this, solder the supplied capacitors to your motor
(see picture).
1. INSTallaTION
• 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“
• The speed-control is now ready to be set-up (see section 6).

Please read the following instructions carefully before you start using your NOSRAM MATRIX BRUSHLESS REVERSE
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 NOSRAM MATRIX BRUSHLESS REVERSE 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.
• Mount the speedo 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: We recommend using the supplied heatsink in order to achieve best performance even under
extreme circumstances. Clean the heatsink and stickerplate before you attach the clear/thin Scotch 468MP
thermal tape to guarantee perfect heat dissipation.
Caution: Use ONLY the supplied clear/thin Scotch 468MP thermal tape to attach the heatsink! Do not us
standard double sided tape to attach the heatsink as standard tape does not transfer heat!
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 the
optional pre-wired cooling fan (#92600) which ts perfectly into the supplied heatsink.
4. INSTallaTION TIPS
Mount the power-capacitor in a position where it is protected in the event of a
crash. The best place is right next to the speed-control (see picture). Secure it
with doublesided tape.

The NOSRAM MATRIX BRUSHLESS REVERSE is supplied with 2.6mm² power-wires without 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.
Caution: Avoid soldering longer then 5sec per soldering joint when replacing the power wires on the speed-
control and motor to prevent possible damage due to overheating of the components!

In setup mode the NOSRAM MATRIX BRUSHLESS REVERSE stores every step when you press the SET button.
All the settings will be stored in the speed-controls memory even if the speed-control 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 using the supplied plastic screwdriver.
You entered setup mode and the SET LED flashes red (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 green 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 reverse on transmitter and press the SET button once.
Reverse setting is stored, LED‘s glow red (MODE) and red (SET).
• This completes the setup procedure and your NOSRAM MATRIX BRUSHLESS REVERSE 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 of the car, and then switch off the transmitter.
• At the start of each run switch on the transmitter rst, then switch on the car.
• For storage of the car, disconnect the drive battery at any time!

8. SPECIal FEaTURES
Internal-Temp-Check System: the NOSRAM MATRIX BRUSHLESS REVERSE 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:
Switch at „OFF“ position.
Keep MODE button pressed while you turn switch to „ON“ (then release button)
SET LED will start to flash red (MODE LED is off), now count the number of flashes.
Basics:
• Thermal shutdown of the speedo would occur at 6 ashes.
• The higher the number of ashes, the cooler the speedo ran (e.g. the better it is!)
• Every ash equals to ~8°C temperature decrease
Example:
you count 10 ashes after the run
10 - 6 = 4 (e.g. 4 ashes „away“ from shutdown)
4 x 8°C = 32°C (e.g. you are 32°C away from thermal shutdown and therefore safe!)
SmartCell System: Ready for the next battery technology – LiPo batteries! NOSRAM’s exclusive and
smart SmartCell System ensures that LiPo batteries can be used safely without accidentially deep-discharging
of the cells. The motor function will be shut-off and the SET LED will flash if the system recognises very low
battery voltage.
Tip: We recommend using value 2 for 4-6 cells NiMH racing purposes, which disengages the LiPo protection.
Automatic Brushless / Brushed Adaption: The NOSRAM exclusive Automatic Brushless/
Brushed Adaptation detects the connected motor type during turn-on/initialisation and adjusts the correct
brushless or brushed operation automatically. No adjustments required by yourself, apart from the correct
connection of each motor type (don‘t forget the hall-sensor-wire for brushless!).
Caution: Keep in mind, when swopping between brushless and brushed motors, that the chosen mode values
will be identical!
Changing Mode settings without the transmitter: At race events you usually do not
have access to your transmitter, but never mind since you can simply disconnect the receiver lead from the
receiver and change the MODE settings as described in section 7 „Mode Programming“.
FreezeDrive Design: NOSRAM’s secret FreezeDrive Design results in lower speedo temperature under
all racing conditions and for both brushless + brushed. Sorry, no further details to be disclosed. Simply a step
ahead of the competition!
Works-Default-Settings: All NOSRAM speed-controls come factory-adjusted (defaults are grey-
shaded above). If you loose track of the modes, you can restore the works default settings. With the transmitter
switched on, hold the SET button pressed while you switch on the speed-control. This simple action returns the
unit to the NOSRAM works default settings.
Power Capacitor: Never disconnect the power-capacitor! It is required for proper function, a special
SuperLow ESR type has been choosen, which offers increased punch and additional protection, therefore only
use genuine NOSRAM power capacitors.
Sensored Brushless Technology: Enhanced Digital allows 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.
3-Way Protection System: The perfect protection against short-circuits (motor), overload and
overheating. If your speed-control faces overload, the motor function will be shut-off for protection and the SET
LED will flash, although the steering function is maintained. Let the speed-control cool down for a few minutes.
If you experience frequent shutdowns, check for the following:
• Correct gear ratio (refer to motor manual for gearing recommendations)
• Power prole setting too high (higher value will heat up motor and speed-control excessively)
• Motor is too strong or motor is damaged.
All modes are available for brushless and brushed motors (speedo adapts automatically). The NOSRAM MATRIX
BRUSHLESS REVERSE features 4 modes which enable you to adjust it to YOUR special requirements. The
factory settings are shown in grey colour.

• How to get into „programming the modes“ Press MODE button for 3 or more seconds.
• How to check the stored values Count the number of flashes of the red SET-LED
(1x = value 1, 2x = value 2, etc.).
• How to change the value Press SET button to increase value by one step.
• How to get to the next Mode Press MODE button once.
• How to leave the programming mode If you are in MODE.4, press the MODE button
one more time
• Table of settings, values and modes: see below (grey-shaded values show „works default settings“)
MODE.4 - Auto-/Dragbrake
allows you to set a slight braking action which is applied in the neutral range. This enables you to simulate the
feel of a brushed motor and also hold the throttle on longer when entering a turn. Your car also has more front
traction with this setting.
For brushless motors you achieve the same natural slowdown as a brushed motor with no autobrake when you
set value 1-2 (for motors with bonded magnets) or 0-1 (for motors with sintered magnets).
