Shaft Diameter: 5mm (.20 in)
EFLM4025H
Kv: 1000 (rpms per volt)
Ri: .026 ohms (resistance)
Io: 2.60A @ 20V (no load current)
Continuous Current: 38A*
Max Burst Current: 58A* (15 sec)
Cells: 4S-6S Li-Po or 12-18 cells Ni-Mh/Ni-Cd
Required ESC: 60A with Heli Mode (EFLA1060)
*Maximum Operating Temperature: 220 degrees Fahrenheit
*Adequate cooling is required for all motor operation at maximum current levels.
*Maximum Burst Current duration is 30 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:
We recommend either E-flite or Thunder Power batteries and list some possible choices for the Power 25 Heli Brushless Outrunner motor, all depending on the airplane application. Battery technology is constantly changing and manufacturers are improving and updating older packs with new ones so the list below may generally have new substitutions.

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 and your operating mode is set to Heli mode.
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 helicopter. 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.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 helicopter blades since spinning blades are very dangerous as the motors produce high amounts of torque.
9.Never disassemble the motor. This will void any warranty.
Safety Precautions:
This is a sophisticated hobby product and not a toy. It must be operated with caution and common sense and requires some basic mechanical ability. Failure to operate this product in a safe and responsible manner could result in injury or damage to the product or other property. This product is not intended for use by children without direct adult supervision. The Outrunner motor case is a rotating part so use extreme caution. Please read the warning information included with your helicopter for safety information related to the operation of a helicopter with blades. Failure to comply with these warnings and/or improper use of the helicopter may result in serious injury.
Installation:
The diagram below shows installation of the Power 25 Heli Outrunner into the JR Vibe 500e. This same diagram is also shown in the owner’s manual for the Vibe 500e. Use the mounting hardware and pinions include in your Vibe 500e kit for installation. If this motor is used in another helicopter application, please refer to the owner’s manual included with your product.
