It’s time to start actually mounting avionics.\u00a0 I’ve held off as long as I could because once the avionics shelf goes in, getting to things gets harder.<\/p>\n

Prior to receiving all the various boxes that go on the shelf, I used blue foam cut into the correct size and shape to determine where everything would go.<\/p>\n

But now it’s time to start mounting things. Some builders will wire the components up on the bench first. But I couldn’t imagine running all the wiring for that temporarily.<\/p>\n

Here’s the two comm radios and single nav radio. I made the brackets which combine the three radios into a single unit for mounting.<\/p>\n

\"2014-03-20<\/a><\/p>\n

Then I added the transponder (which actually attaches to a mounting tray.<\/p>\n

\"2014-03-20<\/a><\/p>\n

Next I put in the mounting tray for the FastStack wiring hub that all the boxes will connect to.<\/p>\n

\"2014-03-21<\/a><\/p>\n

And finally the Audio Panel. The AHRS, VPX, and trim controller sub-shelf had already been mounted.<\/p>\n

\"2014-03-21<\/a><\/p>\n

Then I installed the shelf into the plane to make sure everything still fit.<\/p>\n

\"2014-04-06<\/a><\/p>\n

Now it’s time to start pulling wires.<\/p>\n

The largest of the wiring assemblies were for the EFIS screens and the Audio Panel. So I put those in first since they have the largest bend radius.<\/p>\n

\"2014-04-15<\/a><\/p>\n

One of the things I was worried about was the connectors for the EFIS screens. The extend towards the avionics shelf and I was worried about whether the installed avionics boxes would interfere with the connections. So I came up with a rather low-tech approach.<\/p>\n

I cut a piece of card stock the size of the EFIS screens and cut out where the connectors would be. Then I taped some long stir sticks that ended on the panel mounting screws.<\/p>\n

\"2014-04-16<\/a><\/p>\n

Then I just put the ends of the stir sticks on the panel mounting holes and I could see where the connectors would end up.<\/p>\n

\"2014-04-16<\/a><\/p>\n

This confirmed that the connectors would not interfere with any of the existing equipment.<\/p>\n

At this point it was time to start pulling the rest of the wires. The FastStack Hub greatly simplified the whole process. But even with that, there are still a bunch of wires.<\/p>\n

\"2014-04-17<\/a><\/p>\n

After a while, it starts getting a little better looking. But still a long way to go.<\/p>\n

\"2014-04-19<\/a><\/p>\n

I felt like I should make sure the panel cutouts for EFIS screens, switch panels and power ports were correct (I had checked them individually but not all at the same time). So I made a stand to hold the panel up and installed all the components.<\/p>\n

\"2014-04-20<\/a><\/p>\n

The only thing left to do is mount the Backup EFIS.<\/p>\n
