Brushless motors must be geared correctly according to temperature.
-Normal temperature range is 30-50c. Lower means the motor is under-geared, higher means it is over-geared and must either be geared down or fitted with additional cooling.
-Maximum temperature is 80c but keep below 65c as a safe limit. Exceeding this will de-magnify the rotor causing motor failure and often ESC failure also. We cannot provide warranty service for this.
-For best performance we recommend using a fan with brushless motors, even at 80-90%+ efficiency they produce 50-200w of heat under load.
