Neat thread and lots of great insight.
I have helped friends build two Vans, an RV-4 and a 7. It is actually very satisfying work.
I looked very hard at building an RV 4 for myself, flew one at the factory, etc. I like tandem seating and the ability to do aero. I even got a runway permit for my farm.
In the end, I decided to just fly with my neighbor, who keeps a J-3 Cub on his farm. We fly gentleman's aero once a month or so except in the winter. I have over 4000 hours in various aircraft so the love of straight and level is long gone
Best of luck.
