I got sucked into learning 3D CAD for the instrument panel.
In about 8-10 hours, I was able to create all of the radios and other items that go behind the panel. I then "Assembled" them into the picture shown below.
It looks like it will all go.
The next step is to moch up the panel. I have already mounted the front-facing avionics. I need to buld the tray and add bracing for the radio stack. Then I will put it in the plane and try to remove it. If all goes well, I will start wiring.
