REFLECTOR: 24 volt electrical system

[Ron Brown]

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=&FamIDq5&DivID=&GID=&Type=2&ID64&TechID=&PSID773 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?
