Weird MMM issue...

[hyper9e]

I have had my MMM for over a year now and it has worked flawlessly in my E-revo. This winter my new project was a Hyper9e, so today I plug in my battery ESC and Motor and when I give it throttle it revs up and kinda floats back down. And sometimes it just randomly goes into reverse . And now it does the triple beep and then flashes red infinity. The BEC wire is slightly damaged but the wire is fully intact and not touching anything. I've tried two motors, two receivers, recalibrating and completely different radios. I hope this is not a noob thread but I am stumped. I made a movie to demonstrate. Its just taking forever to upload so i'l put it in the next post.
