I took apart the whole panel and subpanel assembly to install all the hardware, then it will be priming and painting time before beginning the wiring

The EFIS can be updated via a USB port, which can also be used to record the flight parameters. The port is at the back of the EFIS, but a port can be installed in the panel using an extension cord. Before drilling the panel I make a test on some leftover angle.



This is where the left USB port will go.



And the right side.



Here is one of the connector strips, it's the one that will be used for the EIS sensors.

Today I translated the templates from yesterday into aluminium parts. This is the bracket with the rear hinge riveted.



This shows the rear hinge riveted to the subpanel.



After some drilling and sanding I had the two locks installed, but I didn't like how the brackets didn't stay closed tight. So I will install two quarter-turn locks (like the one in the middle).



This shows the locks under the panel with the locks closed.



And a view from the underside. I think I will replace the butterfly screws with some slotted screws to take the out of the way of the passenger's legs.

Not much progress today as I made a few cardboard templates for the fuse block panel. The fuses won't be reachable in flight but shoud be easy to reach on the ground.
The support will be hinged under the right side of the panel.
Before beginning, I install some parts that might cause some interference : the cigarette lighter plug, the alternate air control, a switch and the fresh air tubing shown in the picture.



I then did some test templates with the four fuses blocks and the diode.
This is not satisfactory as the lower block will interfere with the panel.



This is the final result with the support hinged to the lower part of a U channel in the back. The upper part of the U channel will be riveted to the subpanel.



This is a picture in situ, taken from the right seat. The support panel hinges down in front of the right rudder pedals.

Today I worked on positionning some parts behind the panel and fabrication the static and pitot pressure circuits.
The picture shows the back of the left EFIS, with the alticoder in palce. The red tubing id for the pitot and the white for static pressure.
I had made some nice schematics for the pressure runs but it proved unrealizable, I will draw a new schematics copying what I did in the fuselage.



This is the AOA CPU, it is bolted to two angles on the left panel rib between the firewall and the subpanel. Once set,access is not needed on a regular basis. The two small tubes pick up the pressure on the red and white circuits seen above.



This is the rear of the GPS and tight EFIS. On the meft the flaps positionning CPU and on the right the trim CPU with the speed switch.
