• Longer runtimes thanks to Ultra-High-Performance SMD-MOS FETs
• Small size
• Super lightweight
• Plug-in-and-drive, fully wired and ready to plug-in
• Improved version of the legendary QUANTUM SPORT series
• Foward/brake control for maximum performance
• APC-2 – Adjustable Power Control
2. INSTALLATION TIPS
• Mount the speed-control 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.
3. CONNECTIONS
RECEIVER CONNECTING WIRE:
This LRP speed-control is equipped with a LRP Multicon receiver wire. As supplied, it will easily fit in all ordi-
nary receivers.
POWER WIRES:
The QUANTUM SPORT 2 series speed-controls come pre-wired using common „Tamiya-/JST style“ battery and
motor connectors. Together with a motor and a pre-assembled battery-pack from LRPs selection of motors and
battery packs, the speed-control can be used instantly without the need of a solder iron.
You can also solder the power wires of the speed-control directly to the motor, if you do not want to use the
supplied plugs. Nevertheless some soldering skills are still required. However please note, that your warranty
may void if you cut-off the plugs. Therefore we recommend using the original power-wires and plugs.
INSTALLATION:
Your QUANTUM SPORT 2 series speed-control comes pre-wired using common „Tamiya-/JST style“ battery
and motor connectors. Be very careful with the correct wire sequence/colours since an incorrect connection
may damage the speed-control!
• Mount the speedo using the supplied thick/black doubled-sided tape.
• Connect the receiver connecting wire of the speed-control with the receiver (position: Channel 2).
• Connect the speed-control to the motor:
Yellow wire
Connect to motor „Plus“
Blue wire
Connect to motor „Minus“
CAUTION:
Be careful with the correct polarity!
• Doublecheck all connections before connecting the speed-control to a battery.
CAUTION:
If a battery is connected with reversed polarity it will destroy your speed-control!
Red power-wire
Connect to battery „Plus“
Black power-wire
Connect to battery „Minus“
• Doublecheck all connections before connecting the speed-control to a battery.
CAUTION:
If a battery is connected with reversed polarity it will destroy your speed-control!
• You can now switch on the speed-control with the On/Off switch.
• The speed-control is now ready to be set-up (please see section 5).
Note:
If your servo has an external FET connection, you have to connect it to the blue FET servo wire of the
speed-control.

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 lower SET-LED flashes green (it will flash until the setup is comple-
ted).
• Leave transmitter in neutral position and press the SET button once.
Neutral setting is stored.
• Hold full throttle on transmitter and press the SET button once.
Full-throttle setting is stored.
• Hold full brake on transmitter and press the SET button once.
Brake setting is stored.
• This completes the setup procedure and your QUANTUM SPORT 2 series speed-control is ready to use.
• If you have made a mistake so far, don’t worry: Switch off the speed-control for about 10 seconds and start
over again.
• After the run, first switch off the speed-control, unplug the battery and then switch off the transmitter.
When you start again, first switch on the transmitter, then plug in the battery and switch on the speed-
control.
• Always disconnect the drive battery from the speed-control, if you are not using your model.

CHECKING THE FUNCTIONS:
Check the LED when moving your throttle stick and you will see if everything is setup correctly.
4. SUPPRESSION
Motors with no capacitors or not enough ca-
pacitors may interfere with the speed-control.
To avoid this, solder the supplied capacitors to
your motor (see picture).
The Schottky diode improves the efficiency of the speed-control/motor combination and provides extra protec-
tion to the brake FETs. Solder the diode in place as shown in the illustration. The white ring must always face
the positive motor terminal.
