Stek,

I was flying 5 cell nicads at the time and had just charged it at the field. Upon checking the voltage before taking off it showed good voltage- like 6+ volts to start.

When I checked the battery after the first flight and before the next flight it was reading a very low voltage- it was a 5 cell pack and was reading just a few volts- like 2-3volts if I remember correctly. Even so, with the other battery also connected to the receiver and turned on, I couldn't notice the bad battery when operating the servos.
