REFLECTOR: 24 volt electrical system

As I understand it, there are multiple advantages to using the 24 volt.
I believe it allows you to use a smaller gauge wire with less
weight/expense, easier cranking, among other advantages.

Andrew,
 
Is there a particular reason you want to use 24 volts?  Since you are
building your own airplane, you have lots more choices for equipping the
airplane and lots more stuff is available for 12 volt systems from the
automotive and marine worlds.  
 
If you have to have 24 volts because of good deals on avionics, then you
could go to http://www.parker.com/frameless/default.asp?substDivId=

&FamID=715&DivID=&GID=&Type=2&ID=364&TechID=&PSID=3773 and order a
replacement 24 vdc motor for your hydraulic pump.
 
I understand the elevator trim system is already 24 volt (slows down the
trim action since the motor runs slower on 12 volts).  You could
probably use a power resistor in series to slow the trim motor down.

I would have liked to use a 24 volt electrical system on my aircraft,
the problem is the hydraulic gear pump system being 12 volt @ 30 amp.
Has anyone flying an XLRG found a way around this issue?
