Re two batteries, was Miracle switch failures

[s.vannostrand at kodak.com]

You are right, the backup battery is the simpler (hopefully more reliable) 
setup.  I understand.

In my experience with circuit board design, I've found regulators to be 
more reliable than diodes.  This is not intuitive, since regulators have 
many internal transistors, but they also have bypass protective circuitry. 
 If the regulator is wrapped in foam and the connectors are stress 
relieved so that they can't weaken, then I'd have no problems having a 
regulator in the circuit.  I

I currently just use one 5 cell NiCd with a RadioSouth 5.1v regulator and 
it's the best setup I've had in terms of consistent performance.  I will 
be repeating this on my next plane.

It is also a point of failure, but not single, backup battery does not go 
through it and you get constant voltage and if you like Li-Ion batteries 
you really need it.  Diodes give isolation but nothing else.  If you have 
access to high quality diodes go for it, I founded some but did not like 
using them after a while.  I would not necessarily use stuff you find in 
Radio Shack. 
 
It is just FYI and how I do things.

If a diode is a new point of failure, what's a regulator?
