My panel kit from Affordable Panels arrived today. Here's the frame:
I also ordered the expensive CNC machined air vents that are made to go with the panel. In the insane world of aviation, a couple hundred bucks for a pair of air vents is totally normal. They sure are pretty.
I found that a corner of one of the panel plates was kind of screwed up, either during shipping or manufacturing:
I pounded it roughly flat with my rivet gun. Once this is filed, smoothed, and painted, you won't know there was ever a problem. Then I match-drilled the panel plates to the frame before calling it a night.
