HELP,confused and upset

Back story the last time I drove my maxx the esc smoked,a mm.So Thats the 2nd bec I tried in my Erevo.I had not messed with the Maxx since then.So I put my HV back in the Maxx determined to drive 1 of my MT's today.Get everything set up,turn it on,and the servos are fried.So now I think both bec's are bad,and chances are the 1 from the Maxx had something to do esc failure,or vice versa.So I guess it's robbing time ,again, for another servo.I think I'll write Castle a nice little note about this.
