If you're curious here are the details on the USB Charger
My design philosophy with the panel is similar to what drove my electrical system choices and that's to find a balance I'm comfortable with. Being a technologist I know it is impossible to completely future proof any implementation. So I did what I tell my customers to do and that was to find what I need now and in the immediate 18 month future. Outside of that window it's too hard to predict... think about the guy who bought the latest and greatest flip phone, the day before the smartphone release...
Some things I expect I might change around are fairly easy to do. For example if once I'm flying I want to move a switch then I can move the actuator and remap the VPX. If I need another charger type I can remove the one above and install whatever Carlington product fits the same dimensions. If I was to do a major avionics upgrade then I can work within the confines of the Aerosport panel and get new panel inserts for $100. Which in avionics land will be the least of my expenses.
Interesting take on putting a the GTN 650 between the PFD/MFD. I guess if I did something like that I would get used to it but the way I see it I'm more concerned with the information on the PFD/MFD. I fly with a GTN 650 now and it's in the typical radio stack place and I have no issues using it. The RV-10 isn't that big that I feel it would be a stretch to reach over and manipulate it. Would be interested to hear from anyone using the Aerosport EFIS 10" panel with a GTN 650 if they feel otherwise.
