Panel rebuild is complete. Started with adding ADS-B (GDL-82) and before I knew it, I was removing old heavy instruments and cutting out the majority of the wiring. Removed vacuum system and associated instruments. All wiring replaced except alternator circuitry and the lighting wires from original switches to the lights themselves. Designed and laser cut a new panel. Added a G5. Replaced the old Narco comm with a new Garmin that has a built in intercom. All the Garmin units (comm, txpdr, adsb, efi, gps) talk to each other for data transfer. Replaced the Piper ammeter and fuel gauges with EI and Aerospace Logic gauges. Probably should refinish my yokes now. Put the plane on scales cause I pulled out so much stuff, now 1110 lbs empty on 8.50s.
