For those don't know, and the ones like me that don't want to know,....DJI has set all P3's up to not fly as fast. Nor will the Ascend or Descend as fast. However, it is not quite as bad as it may sound though. The speed reduction will not be affected until either the Temperature of the battery reaches a set point, or if one of the battery cell's reaches a set point in Volts. The boss says this was done by reducing the amount of throttle input. It's possible that most may not even notice a change.
