EFLM1150

Kv: 1380 (rpms per volt) Io: .38A @ 8V (no load current) Ri: .5 ohms (resistance) Continuous Current: 7A* Max Burst Current: 9A* Cells: 6-10 Ni-MH/Ni-Cd or 2-3S Li-Po Recommended Props: 6x5 to 8x3.8 (3-cells) or Up to 10x3.8 (2-cells) ‘Slow Flyer’ Brushless ESC: 9A – 12A

* Maximum Operating Temperature: 220 degrees Fahrenheit
* Adequate cooling is required for all motor operation at maximum current levels.
* Maximum Burst Current duration is 15 seconds. Adequate time between maximum burst intervals is
required for proper cooling and to avoid overheating the motor.
* Maximum Burst Current rating is for 3D and limited motor run flights. Lack of proper throttle management
may result in damage to the motor since excessive use of burst current may overheat the motor.

Battery Choices:

There are many Li-Po battery brands on the market with several choices for consumers. We recommend
either E-flite or Thunder Power batteries and list some possible choices for the Park 300 Brushless
Outrunner motor, depending on the airplane application.

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 (EFLA248), 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 or you no longer wish to use them, never cut the motor wires. Remove
them by properly de-soldering 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 propeller
during operation. Spinning propellers are very dangerous as the motors produce high amounts of
torque.

9. Never disassemble the motor. This will void any warranty.
