I worked on fixing my mistakes today and made progress on planning my avionics install. I test drilled holes in one of my other scrap panels to check spacing on the switches and CBs. They worked out! I moved on to laying out the avionics shelf. Everything will fit but it's fairly tight. I'm planning to build a tray for the VAL radios to slide into. Dimensions for the panel layout are below.
