* 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 full high power and limited motor run flights. Lack of proper throttle
management, especially on 4S operation may result in damage to the motor since excessive use of burst
current may overheat the motor.
