My friend Klaus Truemper has written a book outlining his piloting experiences over the past 45 years most of which were in his Zenith CH601HDS. He completed his 601HDS in 1995 and currently has around 2500 hrs on it. He has covered much of the United States several times in it. Modifications include flush riveting and self designed wing root fairings. Very few people have gotten as much out of such a basic Homebuilt. This is a good read for pilots and non-pilots as well.
It is a fantastic book and is available at Amazon.
