RE: t-rex 450 motor surge
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.
