Hello David. I am scratch building and keeping a log at mykitlog.com/sunmanav8. Do you have pictures of you project that are accessible from the web? It's very helpful to follow the work of others like Ron Lendon and Larry Winger, both of whom are using Corvair power. I was planning on building a Corvair motor but after reading of Mark Langford's 3rd crank failure am reconsidering. The UL Power 350iS used in the Zenith 650 demo plane is looking like a great option but it has no history and is expensive.
Stay in touch. I'm looking forward to following your progress.
Developed specifically for Zenith builders (by a builder) these videos on DVD are a great help in building your own kit plane by providing practical hands-on construction information. Visit HomebuiltHelp.com for the latest DVD titles.
