RE: 5 cells unregulated
Mike,
There is never an issue with 5 cell as far as any modern receiver goes, they actually operate internally down around 3V, they have their own built in regulator[8D], this gives a safety margin when a cell shorts in a 4 cell pack, had it happen to me once, servos were reeeal slow but the receiver hung in there.
Now servos, that's another story, make sure to check the specs for your particular servo

RE: 5 cells unregulated
You had a cell short in a fully charged pack during flight? May we assume you did a preflight loaded voltage check and all was well? The question then becomes where did the all the energy go when the cell shorted? There was a lot to be dumped and it would leave some evidence. I am interested because in my 50+ years of R/C I have never seen a sell short in flight, switches and wiring short, but never an internal cell short.

Hi Red,
Do you realy want to know
, actually the cell was shorted or dead from before preflight, got no response from the ESV, but the radio seeemed "fine", assssumed that the connector on the ESV was bad (wrong) well I got away with it that one time, wont ever pull that one again
Regards,
Pete
P.S. My Astro Watt meter does not "lie" to me, it tells me exactly what I need to know, if the meter shows 10A at mid stick and the max current target for WOT that my system is good for is 10A, I power down real fast[X(]
Always enjoy reading the Battery Clinic.

Red, I had it happen once in some 50 years of flying NiCads. No electrical damage was done, just a crashed plane.
