E-flite Hacker E3-37 Brushless Inrunner Motor, 3700kV - Manual (Page 2)

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. Recommended controllers brands include E-flite (EFLA311), Castle, and Hacker.
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. 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.
Note: 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.
