These are the actual plans and drawings I received from Zenith Aircraft Company. At first glance, they seem a little intimidating, but after studying them for a while, they begin to make sense. The great thing is that everything, and I do mean EVERYTHING is specified in the plans.The photo guide assembly manual is helpful too, although it becomes less and less so as you progress into the project. I guess Zenith figures that you know the drill by the time you get finished with a couple of assemblies. There are times when the photo guide deviates from the plans. In that case, you're supposed to give the plans first priority.
