3. specifications
• 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, anten-
na 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.
4. installation tips
2. connections
RECEIVER CONNECTING WIRE:
This LRP speed-control is equipped with an LRP Multicon receiver 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: • #81910 (20cm) • #81920 (10cm)
POWER WIRES:
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 replacement power wire set
available: #82505

user manual
BRUSHED MOTOR:
• Blue/Yellow power-wire
Speedo MOT.A/MOT.B to „Minus“ on the motor.
• Orange power-wire
Speedo MOT.C to „Plus“ on the motor.
BRUSHLESS MOTOR:
• 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.
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 recom-
mend using the optional pre-wired cooling fan (#82500) which fits perfectly into the supplied heatsink.

The LRP SPX Competition StockSpec 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!
• Connect the speed-control to the receiver (position: Channel 2)
• 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).
5. suppression
ONLY FOR BRUSHED MOTORS!
Motors with
no capacitors or not enough capacitors may
interfere with the speed-control. To avoid this,
solder the supplied capacitors to your motor
(see picture).
