This I do not understand. Remember at the beginning of this thread I stated that I don't really have a great understanding of anything electrical. So, two identical planes, with identical receivers, and identical servos, but one having a 4.8v battery and the other having a 6.0v of the same mAh, will give you different flight times? And the 4.8v battery will actually win out.

One thing to remember about 4.8 v 6 volt packs of equal capacity is that the 6 volt pack gives you about 20% LESS flying time. due to the higher current drain.
