I've spent a lot more time over the last week working through wiring and reading up on electrical systems. Tonight, I decided to start seriously laying out the panel so that I can better visualize where everything is going to go. I used the Draw.io program for this too and I think it turned out really well. I used overall measurements from Garmin literature and then imported an image of the component to trace some of the detail. After looking at all the cool panel options from Aerosport, I think I'm leaning towards using the stock panel now. I'm planning on a GTN650 instead of a 750 with just two G3x screens. Looks pretty good with a GTN650. With the com2 radio and transponder mounted remote, I think there will be adequate room. And currently thinking regular circuit breakers instead of the VPX that everyone seems to be doing. I may change my mind on that by the time I'm ready.
