Today I did some more work on the map box. I started to fit and drill the angle pieces that support the forward portion of the map box and stiffen the subpanel where I cut the large hole. This was a great use for the leftover section of stiffeners from the rudder. I didn't drill the angles to the box yet, first I have to make sure the subpanel is positioned correctly to align with the skin. I'll mark it next time I fit for forward skin.
I also started fitting the trays for the radio stack. I still need to attach the rear supports to the sub panel and set the correct spacing between the radios.
