 EFLM4015A Technical Notes 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.
