The left wing has a support for an ADAHRS unit for Dynon avionics, but it can be used for other systems as well. I installed it even though I am not sure whose avionics I am going to go with. I know I can make it work with the Garmin magnetometer so I am OK either way.

I also made on last sweep for questionable rivets on the top wing skin. I found less than half a dozen that Kathy helped me change out.
