What's in the record
Aircraft model, serial and firmware after refresh. Every part replaced with part number and source. Each calibration performed and its result. Each test-flight check with the measured value. The flight log file. The Part 107 pilot's name and certificate number. The warranty terms.
Keep it with the aircraft. It's what an insurer, a safety manager, or the next buyer will ask for.
