I've spent quite a bit of time thinking and re-thinking the electrical system. I've read the AeroElectric Connection by Bob Nuckolls and Aircraft Wiring Guide by Marc Ausman. Both have been very helpful. I think I'm going to go with one Main Battery, two Alternators and a TCW IBBS plan based on the AeroElectric Z-12 design. I was thinking of a VPX-PRO design but I'm concerned about the added complexity. However, the VPX Installation and Operating manual has also been a good resource to find what is and isn't needed in the basic plan. I think I have a draft of the plan complete but will get it looked at before I get too deep. For ignition I've been reading about P-MAGs. Also drafting up a Instrument Panel design. Planning on three G3X GDUs for PFDs and MFD and a G5 as an ISFD with a GMC 307 Autopilot and GTN 635 Nav.
