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. Please be sure the timing and PWM
switching frequency is set properly on your controller.
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.
5. Re-install the donut washer against the bearing.
6. Re-install the shaft collar back against the washer and bearing.
7. Retighten all setscrews making sure you line up with the flat spot on the shaft.
