I had a Nmp pack that lost a cell after the first takeoff on the Friday before the Gardnerville, Nv contest. This pack had 50 or so flights on it. Was fully charged the night before.. Checked with a load before the flight.. I took off, came back across the field and had lockout from the low voltage. Scott Covey checked the voltage in the individual cells and found one at 0.. Cost me a great plane. I will not use Nmp again.. Now I fly with lipo's for my rec pack.. Wish I would have done the duals on that one as it was my "late" brother Jevan's plane..

Now you have heard of a failure..
I still stand by your switch-regulators though Jim.. They are the only ones I run.. Which brings me to the Q of what do you have for 33% planes? Or can I use these same ones..

Thanks,

C
