I think there have only been a small handful of failures out there so
far.

If the electrical system is clean and put together well, then the
chance of a failure is probably too remote to worry about.

FAI and contests allow for a gap of several minutes, so a simple switch
for dual batteries is good enough if you're worried about the battry
running out on you - or you forget to charge one.

As you say, most recorders will only start a new file after power has
been removed for about 5 minutes, which is provided for in the current
FR Specification.

However some earlier recorder, the Volkslogger for example, were
designed before this provision was written in, and will always start a
new file after a power-down, regardless of duration.

Even then, if it is 'beyond reasonable doubt' that there was no
intermediate landing, more than one file may be accepted.
