Y'all have a long way to go when it comes to unique voltages on an airplane.
We used 230/400 volts ac, "wye" four wire 400 Hz, on the B-1 to reduce the
wire size and weight. The double voltage to cut the current by 50% in
comparison to 120 volt systems, cutting the total wire weight by nearly
half, and 400 Hz to cut the size of all magnetic components (like
transformers and motors and such) to as little as 1/6 th the 60 Hz size.

Since I don't have quite so many miles of wiring in my Lancair, 12 vdc works
just fine. Of course I subscribe to the KISS principle, which ain't all that
bad for such simple airplanes. (Lancair IV's excluded, since they border on
the "not simple").

Point being, don't get carried away.
