Hall-Sensor wire
HALL-SENSOR WIRE: This bi-directional multipole wire, which is supplied with all LRP sensored brushless speed-
controls, connects the speedo and the motor. Do not alter or modify this cable! Make sure, that the plugs have a
proper and tight fit and are always clean.
POWER WIRES: The unique splitted solder-tabs allow easy and convenient replacement of the power wires. Ne-
vertheless some soldering skills are required. Talk to your local hobbyshop if you are concerned about soldering
the wires yourself.
Caution: Avoid soldering longer then 5sec per soldering joint to prevent possible damage to the motor due to
overheating of the inner components!
• Install the motor in the model.
Caution: The maximum length of the motor
screws shall not exceed 8mm.
• Connect the power wires of the speed-
control and the motor.
Make sure, that the sequence is correct by
checking the color code and the letters:
- MOT.A = blue wire
- MOT.B = yellow wire
- MOT.C = orange wire
• If you‘re using a sensored speed-control:
attach the hall-sensor wire to motor and
speedo now.
• Finally check all the connections before using the motor.

Please pay special attention to our gear ratio recommendations! A wrong gear-ratio causes excessive heating
and may result in motor damage or thermal shutdown of your speed-control. Take your kits manual to find the
correct pinion. Motor temperatures should be monitored, they should never exceed 100°C (= 210°F).
The following gear ratios are only a recommendation and a good starting point. The actual gearing may vary due to
different speed-controls, speedo profiles, motor timings, tracks, track conditions and/or batteries:

Due to the maintenance free design of the LRP Vector X20, it is not necessary to open the motor frequently under
normal conditions. It is just recommended to check that all screws are still securely fastened.
Nevertheless, if you intend to check the ball bearings and oil them from time to time or want to change to another
rotor type, you can of course disassemble the motor.
Disassemble the motor:
1. Loosen the center endcover screw and remove screw, plastic endcover and timing insert.
2. Remove PreciSensor™ Assembly
3. Loosen and remove the long/outer 3 screws and gently slide off the front aluminium housing.
4. Remove the o-ring and shim from the shaft.
5. Carefully pull the rotor out of the housing and place it in clean towel or designated rotor container.
6. You have now access to both ball bearings for cleaning, maintenance and replacement. You may also use
compressed air to clean the inside of the motor after you have removed the bearings.
Be careful with correct shim/o-ring position during re-assembly and avoid overtightening the screws!
LRP‘s exclusive sensor positioning system allows precise control for best and most efficient performace. Fast,
simple and super-accurate timing adjustment using the five supplied timing inserts (27.5°, 30°, 32.5°, 35°, 37.5°).
By altering the timing, you move the powerband and alter the characteristics of the motor.
New: our PreciSensor assembly is now coated with a special liquid to make it fully waterproof!
All you have to do, when running in dry/damp conditions, is to protect the sensor wire lead (using rubber gum!) and
of course the rest of your electronics such as the speed-control, receiver, etc.
Four important things to remember about timing adjustments:
1. Higher timing results in higher rpm but worse efficency/torque and vice versa.
2. Higher timing requires shorter gearing!
3. Timing adjustments should be done by experienced racers only, others please leave timing on standard setting!
4. Proper direction of the timing insert is if the degree letters are facing you with the insert instaleld in the motor.
To alter the timing, proceed as following:
1. loosen the center endcover screw and remove screw and plastic endcover.
2. change to desired timing insert and rotate sensor assembly slightly.
3. reattach endcover and tighten M2 screw carefully (do not overtighten this screw!
Do not use aggressive advanced timing speed-control profiles with Vector X20 motors!
Because of it‘s unique design, with HVS Technology and PrecisSensor System, such profiles are not required to
gain same performance as normal motors (with extreme speed-control timing advance). With X20 motors such
profiles only result in higher motor temperature but not higher performance!
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 destroy 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.
• 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
electroconductive 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.
• Avoid overtightening the motor screws. Damaged threads are not covered under warranty!
• Avoid overloading the motor due to wrong or too long gear ratios.
• Never apply full throttle if the motor is not installed. Due to the extremely high RPMs without load, the
motor can get damaged.
• 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 possible damage
to the product due to overheating of the components. Use a high power soldering station with at least 60W for
soldering.
The manufacturer can not be held responsible for damages, which are a result of non-observance of the
warning notes and security advices.
