The next day:
Dominik (swisseagle on VAF) invited me to join him at Flugplatz Birrfeld near Lupfig, and I was happy to oblige.
He introduced me to Dan and Bernie. Bernie was a bit busy applying software updates to the glass panel in his RV-7A (never had to do that to my steam gauges) so I didn't get much of a chance to talk to him at the beginning of the day, but I was able to spend time with the other two.
Dan has already built aircraft. Today was going to be his first RV ride, his RV-Grin installation sortie, if you will.
Dominik finished his RV-7A about a year ago.
The first thing that drew my eyes when he pushed it out of the hangar was the fit between the front corners of the tip-up canopy skirt and the fuselage: I'm almost certain it's waterproof, because I couldn't see any gaps big enough to admit an H2O molecule.
Then, casting my eyes wider, I saw that that attention to detail permeated the entire aircraft: It's the most immaculately perfect RV I've ever seen. Everything fits. Everything is flush. Everything is clean and shiny. Little custom touches which make it visually and functionally better (the custom canopy latch; the LCD autopilot panel). The culmination of a 12 year build, and every detail is beautiful.
After waiting for an AN-2 to get out of the way of the fuel bowser, Dominik and I departed to the South in company with Bernie and Dan. Down towards Interlaken and The Eiger, a foray into the mountains for some air-to-air photo-ops. Smooth, clear air at 12,000'. Majestic views.
We landed at Neuch?tel, on an approach from the West that follows descending terrain less than 100' from houses. Probably good for neighbor relations to stay on idle power

Rolled-out with skydivers touching down on the grass next to the runway on our left.
Dan's RV-grin was successfully attached. I think he might have ordered a tail kit on his phone before we landed.
Lunch at a French restaurant by the lake, accompanied by some more E/AB people who showed up (a Rutan VeriEze). Our mountain detours also meant that we were beaten to lunch by one of the guys we were joking with about speed.
I bought the food this time :-)
Once again, our trip back was via the direct route (Bernie was running out of brownie points with his wife). We followed a ridge line for 100km or so, full of gliders and paragliders which showed up on Dominik's moving map thanks to his FLARM collision avoidance system, which seems very common and popular in this part of the world.
This is a jaw-droppingly beautiful part of the world, and there are more friendly and generous RV people here than I had time to meet. If you're in Europe, where traveling distances are short and national borders are close together, you won't regret a visit to Switzerland.
