Question</DIV>

<DIV>>>>NiCad's normally fail shorted and you have enough power to
land. NiMh's normally fail open and you will need another airplane to go with
your new battery.<<<</DIV>
<DIV> </DIV>
<DIV>Some of the old radios (Proline, for instance) had diodes across each
cell in the airborne pack, in case a cell went open. Also, if a cell died
(lost voltage) it would minimize the problem by preventing a cell from reverse
charging.</DIV>
