OK, I know I am teetering on the edge of heresy by disagreeing with Carl (given the disparaties in our knowledge and experience), but I have an anecdote that comes under the heading "all indians travel in single file, at least, the only one I ever saw did"...
I have a friend who built one of the kits (I forget which one, I didn't know him then, but it seems to me it was a Murphy of some variety), and decided to tackle a certified aircraft restoration. So he hold his kit built and bought a Pacer project.
He is finding that restoring a certified airplane is much more difficult, and time consuming, than building a well-designed kit.
Of course, if my memory serves (RIGHT!) the kit was riveted aluminum, and the airplane he is trying to restore is rag.
