Operating Instructions:
1. This brushless motor requires the use of a sensorless brushless speed control. Failure to use
the correct speed control may result in damage to the motor and/or speed control.
2. When mounting the motor, be sure the correct length of screws are used so damage to the
inside of the motor will not occur. We suggest you use the mounting hardware included with
your motor. The use of long screws will damage the motor.
3. You may connect the three motor wires directly to the controller with solder or use connectors
such as gold plated brushless bullet connectors (EFLA241), which will also need to be
soldered properly to your wires. The three motor wires can be connected in any order to the
three output wires or output port on a sensorless brushless speed control. Be sure to use
heat shrink tubing to properly insulate the wires so the wires will not short. Shorting may
damage the motor and speed control.
4. If you add connectors and you no longer wish to use them, never cut the motor wires.
Remove them by properly desoldering them. Shortening the motor wires is considered an
improper modification of the motor and may cause the motor to fail.
5. When you connect the motor to the esc, check the rotation direction of the motor. If you find
the rotation is reversed, switching any two motor wires will reverse the direction so the motor
rotates properly.
6. Proper cooling of the motor is very important during operation. New technology has brought
much higher capacity batteries with higher discharge rates, which can cause extreme motor
temperatures during operation. It is the responsibility of the user to monitor the temperature
and prevent overheating. Overheating of the motor is not covered under any warranty.
7. You can install the propeller on the motor shaft after you have confirmed proper rotation
direction. Also consult the instruction included with your sensorless electronic speed control
for proper adjustments and timing.
8. Once the battery is connected to the motor, please use extreme caution. Stay clear of the
rotating propeller since spinning propellers are very dangerous as the motors produce high
amounts of torque.
9. Never disassemble the motor. This will void any warranty.
Reversing Shaft Installation
This Outrunner motor has a shaft, which exits through the rotating part of the motor. If you want to
reverse the shaft to exit through the fixed part of the motor, follow these instructions carefully for
changing the shaft installation. NOTE: The user assumes all liability for damage that may occur.
1. Loosen the set screw on the shaft collar and remove the collar from its location against the
bearing.
2. Remove the small black donut washer that rests against the bearing.
3. Loosen the set screw in the rotating part of the motor.
4. Slide the shaft through the motor. It may be necessary to use a small hammer to lightly tap
the shaft. It is very important that you do not bend the shaft in this process so use extreme
caution to assure this does not happen.
