1. With the motor direction set to CCW, take the graduation/value after “CCW” on the motor case as the
starting point when adjusting the timing. With the reversed triangle pointing at a value /graduation,
the smaller/bigger the value, the smaller/bigger the timing. The timing is 40 degrees in picture 1.
2. With the motor direction set to CW, take the graduation/value after “CW” on the motor case as the
starting point when adjusting the timing. (With the reversed triangle pointing at a value/graduation,
the smaller/bigger the value, the smaller/bigger the timing. The timing is 20 degrees in picture 1.
3. The motor timing is 30 degrees by default (as shown in picture 2). The motor timing should be within
30 to 40 degrees if you want to activate the Turbo timing. And the timing can be within 20 to 40
degrees if you have no intention to activate the Turbo timing.

07 Assembly and Disassembly
1. Install the motor
The motor mounting screw specifications are two groups of M3 and two groups of M4. The motor screw hole can
be locked into the depth of 5.5mm. Before installing the motor on the vehicle, please carefully confirm whether
the specification of the matching screw is appropriate, so as to avoid damaging the motor by using too long or
too thick screw. Generally, it is recommended to use m3 / M4 screw with length not longer than 8mm, which is
determined according to the thickness of frame motor mounting base.
2. Motor connection
• When welding / connecting the motor and the electronic speed controller (ESC), please pay attention to the ESC
marking to ensure that the terminals on the ESC and the motor are one-to-one, that is, wire A of the ESC matches
wire A of the motor, wire B of the ESC matches wire B of the motor, wire C of the ESC matches wire C of the motor.
• Make sure the sensor wire is clean and undamaged, and pay attention to the orientation of the sensor wire.
Connect the sensor wire to the terminal of the motor and ESC in the correct direction.
3. Inspection
Before power on the remote control vehicle, please check the reliability of the motor installation and the
correctness of all connections.
In order to make the motor have longer service life and higher efficiency, we suggest to regularly check the bearing and clean the dirt in the
motor. The specific time depends on the frequency of using the motor and the site conditions.
When installing, please follow the steps in the following assembly drawing; when disassembling, follow the reverse steps.

Sensored Brushless Motor
• Never leave this unit unsupervised when it is powered on.
• All wires and connections should be well insulated. Short circuits can possibly damage the products.
• Avoid incorrect connections between the electronic speed controller(ESC)and the motor.
• Never allow this product to come in contact with water, oil, fuel or other electro-conductive liquids.
If this happens, stop the use of your product immediately and let it dry carefully.
• Please carefully check power devices and manual of car frame to ensure the power pairing is
reasonable. Avoid wrong pairing to overload and damage the motor.
• Never apply full throttle if the pinion 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, your model RC may lose control.
• Never allow the motor case to get 100 degrees Celsius(212 degrees Fahrenheit) because the
magnets maybe demagnetized by high temperature.
• When the built-in chip of motor is matched with Hobbywing XeRun XR8 series of ESC, the ESC can automatically identify the motor and build a pure sensor mode power system, providing better manipulating
performance and more delicate manipulating feel.
• When this motor is used together with Hobbywing XERUN XR8 PRO G2 ESC can start more effective turbo timing than the last generation of system. The motor can release maximum power instantly. The maximum
speed can be promoted by 50%. Easily win your rival.
• The motor adopts the patent technology of "error-free" Hall sensor system, the independent high-speed and high-precision encoder always outputs pure rotor position signal, which effectively avoids the interference
of sensor signal and makes the motor work stably in sensor state.
• The mechanical turbo timing of motor can be adjusted from 20-40°. It is convenient for driver to calibrate accurately output power of motor and meet power requirements of various application.
• The motor has low cogging effect and small torque pulse. It is very smooth at low speed and has superb manipulating performance.
• The protection grade of Off-Road motor is IP5X. Its excellent dustproof performance can easy to deal with various Off-Road dusty track environment.
• On the premise of improving the performance, the design of 4268SD G3 is optimized which extremely reduce the weight of motor. The weight of 1900KV / 2200KV is 20g / 45g lighter than peers. The light motor is
convenient for the driver to adjust the balance performance of the vehicle.

Reasonable selection of gear ratio is very important. Improper gear ratio may bring you great loss. Please according to the following points to select the correct gear ratio!
1. The working temperature of the motor
The motor temperature should be lower than 100 degrees Celsius (212 degrees Fahrenheit) in operation. Because high temperature may cause the magnets to get demagnetized, the coil to get melt and short
circuited, and the ESC to get damaged. A suitable gearing ratio can effectively prevent the motor from overheating.
2. The principle of selecting gear ratio
To avoid the possible damage to ESC and motor caused by the overheat, please start with a small pinion/a big FDR and check the motor temperature regularly. If the motor and ESC temperature always stay at a low
level during the operation, change a big pinion/a low FDR and also check the motor temperature regularly to ensure that the new FDR is suitable for your vehicle, local weather and track condition. (Note: For the
safety of electric devices, please check the ESC and motor temperature regularly.)

1、当电调设置的电机转动方向为CCW时，以电机壳上CCW后面的刻度为准，箭头指向的数值越
小，代表进角越小，箭头指向的数值越大则进角越大。如图一所示，该情况下进角为40度。
2、当电调设置的电机转动方向为CW时，以电机壳上CW后面的刻度为准，箭头指向的数值越小，
代表进角越小，箭头指向的数值越大则进角越大。如图一所示，那么该情况下进角为20度。
3、电机出厂默认进角为30度，如图二所示，如需开TURBO，建议电机进角在30-40度之间调整，
如不开TURBO，电机进角在20-40度之间均可。

齿比的合理选择非常重要，不合适的齿比可能会给您带来重大损失。请遵守以下要点来正确选择齿比！
1、电机的工作温度
电机在工作时，温度应低于100°C（212°F）；温度高于100°C时，将会使电机转子磁性减弱，且线圈可能出现局部烧熔短路现象，产生大电流而损坏电调。选择合适的齿比可以有效
防止电机过热。
2、齿比选择原则
为防止电机过热引发潜在危险而导致电调和电机损坏，请从一个最少齿数的电机小齿进行齿比配置，并随时检查电机温度，这是唯一能确保电机不过热的方法。车子在行驶途中，如果电机及
电调温度一直处于稳定的低温范围内，您可以试着使用齿数较多的小齿，并密切监测电机温度，以确定更改后的齿比是否适合您的模型车、当地气候及赛道条件（请注意气候及赛道条件不是
恒定不变的，而是经常会发生变化，所以频繁地监测电调及电机的温度是一项重要的日常操作，它可以确保您的电子设备长期稳定地工作）。
