I will not be using speed controls internal BEC's any more. Even though I pushed the limit and used 6 mini analog servos (which the manual said it would handle and many people told me don't do it) it overheated in flight and I lost all control and got to watch it glide into a fence at a 45 degree dive from 250-300 feet. there is no question in my mind it was the BEC in my E-flite pro 60 amp speed control that did it.
