Yesterday I received the sub-panel structure back from Aerotronics, which they had modified for the avionics installation. They also included the clear plastic template for the panel. Today I installed the sub-panel parts and test fit the panel template. I didn't spend long because I also had to dig my hangar and my flying RV out of the snow (as you can see in the pictures). Then I headed out for some hot coffee. The hanger is not particularly cold, especially with snow insulation, but shoveling snow is cold work.
