Panel Layout

 After a lot of work on both the panel and wiring diagrams we think we've got our final layout.  FreeCAD was used to layout the panel in 3D.  This allowed us to check for behind the panel obstructions.  The COM radio (Garmin GTX200B) was the main item we had to worry due to some cross support tubes.  KiCAD was used to draw the wiring diagram (schematic).  This allowed us to know how many switches and circuit breakers to place on the panel.  Hours:20
