E-flite Six-Series Brushless 2700Kv Motor (28mm) - Manual (Page 3)

NOTE: For a more secure press fit, you may add Loctite® Threadlocker Green to the inside of the pinion before
installation.
Removing Pinion Gear
1. To remove the pinion gear, it is recommended to always use a gear puller to prevent damage to the
pinion and shaft. We recommend the E-flite Pinion Puller (EFLA212).
NOTE: Never reuse a pinion gear once it has been removed from the shaft.
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.
