mmm v3 died.

[Rnemhrd]

I ran my mmm v3 for the second time on 5s and it just stopped. It has a very dim red led lit. It still sparks when I plug the batteries in but thats it. There is a little burnt electronics smell. I know I have to send it in and it will be covered, but anyone have any idea what may have gone wrong? It was about 5 min. in to running and the motor was 90f the lipos were 100f and the mmm was 76 from what I can read through the case. Thanks.
