I ended up having the use an orbital sander to take a little bit off of two of the legs to get things to sit precisely flat.
I also installed some replacement window shades in the workshop to limit the heat that'll being coming in during the summer.
My workshop is in the area that would normally be a formal dining room, but I've never actually needed more than the breakfast table area that is adjacent to the kitchen. Some friends have suggested plastic sheeting to curtain off the workshop from the rest of the house, and possibly HEPA air filtration to keep the dust down. I'll have to see how much of an issue that actually becomes once I get started, but I'll definitely be doing messy things (like painting and sanding fiberglass) outside or in the garage.
Although I ordered both the empennage and wing kits in January 2022, the wing kit is scheduled to be the first one arriving. Crating for the wings is currently scheduled for May 2 2022 - May 6 2022, with shipping to be done after that....
