My panel plan has had major changes over the past few years, but now the changes are smaller and driven by market pricing of alternatives. Structurally, the plans composite panel is replaced by aluminum. Thickness of the aluminum is .041. I don't know the alloy, but suspect 2024. Composite "piers" tie the aluminum to the fuselage at the right, left and bottom center. The radio stack ties the panel to the F25 behind it, again adding stiffness. Aluminum angle at the top carries red LED's and adds stiffness. A busy panel with old school round guages and small screens is now glass panels + ipad. Switches are now (mostly) a row at the top of the panel - see the photot of the test fit. I will work on some other parts of the build, then buy the avionics and cut the final panel. After mounting everything I will set the fuse block locations and do wiring. (Sooner or later I have to buy a lot of electronics. But not today!).
