Many days have gone into installing the various boxes that follow. Finding spots and fitting, it all takes time.

This VPX fuse system was a particular challenge. It needed a spot that had plenty of room either end for the large cables.

Above the rest of the avionics was always the preferred option and how to attach it went through many iterations. I had intended rails spanning the cavity area and sitting it on these.

In the end I use two clickbonds which hold the lower rack then this ‘arrangement’ at the front. I had to keep a good distance forward (back in the photo) to clear the main screen G3X fan!

Now with a lightening hole at the front I can also easily get in to the back nuts with a socket extension to detach the VPX unit. It is also integrated with the main avionics.

The idea here is to have as much as possible removable in one big package at once. This way many things can be wired outside of the plane sitting on a bench. This has always been a part of my brief.

This safety trim box was mainly full of air with a beautifully made circuit board on the bottom. I’d say this box is ripe for a real trim. Sorry about the pun.

Here we are after a cut and shut. A much slimmer box.

After a huge amount of trying elsewhere, the trim box has ended up here. The usual clickbond treatment although only three of them is plenty. Clean up and glass will follow.

The electronics for the heated pitot ended up in that little box. Its installed on the same side as the pitot wires.

These are the two AG6 units to give me fuel levels and various warning displays. It was a ridiculously difficult job to fit them both into this small box.  Space is at a premium.

I then went to heroic lengths to make a mount that would fit on top of the Garmin GTN 750 tray out of odd bits of aluminium, rivets and nut plates.

It fits! It is installed and easily removable with the top hatch off via the side screws. Again the brief was to have this a part of the panel mounted avionics. These can be left in place when connected and the whole thing taken out as required.
