9/22/12 - Had a chance to talk to fellow Zenith builders which was invaluable. Learned more about the Jabiru, UL Power and Viking engines. Was quite impressed with the Viking fuel-injected engine so much so that I decided to take a Demo flight with the owner of Viking, Jan Eggenfellner. After that flight, I was sold. It was very powerful and did not have the vibration that I expected or excessive noise either. I had finally decided on the powerplant for my build!
