Status: offline 		 It is not normal and could be a bad cell in the battery.  On some esc's, it will surge and wag the tail when the battery is low.  Don't forget, it is also under a load and may be going under the cut off margin.  I don't think it would be the motor, but is posssible.  I was tend to lean towards the battery or possibly the esc.
