Amazing accomplishment. I wish I had the time, money, and patience to build my own. I bought one flying and I love it. Before I went looking for a plane to buy, I did transition training with Tom Berge in Minneapolis. He has a well equipped RV7A with 180hp and C/S prop. Great panel. He was great to fly with, and is a wealth of RV knowledge as well. I highly recommend him!
