Installed and mostly wired in the panel is a Dynon FlightDek D180, Garmin GPSMap 496 w/panel mount, Radio (not sure what one at the moment) and a few other items. The biggest item I need to add is ADS-B. I would like to have ADS-B in to the D180, but that might not be feasible. I like the EFIS features, the autopilot servos are installed. Lots to test/validate and finalize.
I'm currently a VFR pilot and someday plan to get my IFR. Current plan is to finish out the plane by adding the Turbo and fly with existing equipment (+ADS-B). While flying the 40 hours off I will be planning the next panel to build and swap in over a few winter months. That would trigger a requirement to fly off another 5 or more hours again as I understand it. Full IFR (for a homebuilt) is the long term goal.
