Does anyone know of an article about a checklist for the 51% rule? I
remember reading the article and would like to find the website to
download it. If I remember, it was a checklist of what parts and
components would be built to be considered 51%. For example, if you
start a kit but do not quite get to the same point as a quick build of
the same plane, what percentage have you built?

Get the manual from FAA - Amateur Built Aircraft Reference Manual.
(AFS-600)
It has a complete checklist for evaluating any project for complience.
