Today I finally got around to finishing the mounting tray for the ADAHRS. I made up the components a while back so I just needed to drill to final size, deburr, paint and rivet. I used nutserts rather than plate nuts since they are all aluminum and have less chance of causing an error with the heading. Since the nutserts are have alumunum threads they don't take abuse well, but the ADAHRS isn't something the gets installed and removed very often.
While I was at it, I also finished riveting on the right side forward canopy deck.
