William,
I actually have such a switch. It works independent
of even having the master switch on. It didn't occur
to me to activate it, but it happened pretty fast. I
had identified a place to ;and, and had just started
surveying recovery options when the power came back. I hope that I would have remembered the emergency
bypass switch, but I'm not sure. I'll be creating an
emergency checklist to keep in the plane should the
need ever arise. I hope it never does.

Steve,
Congratulations on the successful outcome -- your
experience fits right into what "Sport-Air" states in their flight testing
course, namely that the most common problem on experimental aircraft in flight
test mode is engine failure.
Can you arrange two paths for electrical to the
"engine bus", one for normal use, and the other coming from second battery via a
separate switch?
