It’s important to select the FDR/gear ratio properly, as improper FDR/gear ratio may cause you great loss. Therefore, please choose the gear ratio by referring to the following points!

1. Operating Temperature of the Motor

The motor temperature should be lower than 100℃/212℉ during the operation. Temperatures above 100℃ will weaken the magnet and may partly melt the coils and eventually damage the ESC (due to strong

current). Therefore, the most effective way to prevent overheat is to select the right gear ratio.

2. Principle of Gear Ratio Selection

To avoid potential risks such as ESC/motor damage or malfunction caused by overheat, please start with a very small pinion first and check the ESC & motor temperatures regularly throughout the run. This is the only

way to guarantee that your motor won’t overheat. If the motor and ESC temperatures remain stable and low in the running, then you can slowly increase the pinion size while monitoring temperatures to determine

the safe gearing for your vehicle, climate and track condition. Because these elements may change, so please keep monitoring the ESC & motor temperatures to protect your electronics from damage.

• (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 (as shown in picture 1) when the motor direction is set to CCW.

• (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 (as shown in picture 1) when the motor direction is set to CW.

• 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.

Assembly/Disassembly

For prolonging the motor life and raising its efficiency, we recommend checking and cleaning the motor regularly. About the frequency, it depends on the times you

use the motor and the track condition. Please refer to the following diagrams to assemble your motor and dismantle it in the reverse order if necessary.

Sensored Brushless Motor

Installation & Connection

1. How to Mount the Motor into a RC vehicle

M3 mounting screws (6*M3) are needed here, as the mounting holes are 5mm in depth, so we don’t recommend using the M3 screws

with the length exceeds 8mm to mount the motor into your vehicle.

2. How to Connect the Motor to an ESC

There are three power wires coming from the ESC must be soldered to the motor. They are usually color coded as Blue for Wire A, Yellow

for Wire B and Orange for Wire C. When connecting the power wires between the ESC and motor, please make sure that you match ESC

Wire A to Motor Phase A, ESC Wire B to Motor Phase B and ESC Wire C to Motor Phase C (this is very important).

• When using a Sensored ESC, make sure the sensor cable is clean and undamaged first and then connect the sensor cable to both the

ESC and the motor in the correct direction.

• When using a Sensorless ESC, swap any two wires if the motor runs in reverse.

3. Recheck the Installation & Connections

Recheck the installation and all the connections before turning on the power.

• Innovative 4-pole-8-magnet "staggered pole" rotor (Hobbywing-patented) with low cogging effect and torque pulsation greatly improves control feel around corners.

• Built-in chip for making the motor be easily identified by HOBBYWING ESCs. When pairing it with a HW 1/8th sensored ESC (i.e. XR8 SCT/Plus), the motor can work in the “sensored” mode at all times with great

output linearity after the identification. The Turbo timing is allowed to be activated for higher output.

• Magnetic ring mounted on the rotor protects the motor from signal interference and guarantees its super stability in the “sensored” mode.

• With the mechanical timing adjustable from 20 degrees to 40 degrees, users are able to have different output power.

• Turbine design implemented by the rotor accelerates the internal air circulation and reduces heat.

• Rebuild-able design (partially rebuild-able) and screw-less motor case for easy routine maintenance effectively prolong the motor life and raise the motor effficiency.

• CNC machined aluminum housing, high purity copper windings, advanced rotor structure, high-quality alloy steel output shaft, high-precision bearings for high durability and smoothness.

• New-style “U” solder tabs at the bottom of the motor for easy soldering and wiring.

• Never leave this product unsupervised when it is powered on.

• Ensure all wires and connections are well insulated before connecting the motor to related devices,

as short circuit will damage your motor.

• Please strictly follow the A-A, B-B and C-C wiring order when connecting an ESC to 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.

• Read through the manuals of all power devices and chassis and ensure the power configuration is

rational before using this unit.

• Never hit full throttle before installing the pinion, as high speed rotation may cause damage to the

motor in circumstances of no load.

• Ensure all devices are well connected, in order to prevent poor connection that may cause your

vehicle to lose control or other unpredictable issues such as damage to the device.

• Stop using the motor when its shell temperature exceeds 100℃/212℉; otherwise the rotor may be

demagnetized and cause irreversible damage to your motor.
