I got the data plate back from the engraver the other day. Alodined under its footprint and riveted it on the tail under the l/h horizontal stab. I finished off today by installing the required Experimental placard on the aft baggage bulkhead, and the N number. This is just a simple vinyl N number that I ordered from spruce, but at $40 it was a better value than trying to piecemeal this together. It's just temporary until paint, but it's pretty cool to be able to step back and see an actual airplane with an actual N number on it.
