Also, a Votec is a modified DR-109. Better known as the 2-place "One Design." It looks like they added a cantilever tail and some I have seen have a scoop on the bottom of the cowl for cool air intake. I am sure there are other changes those are just te few that jump out at me. Here is a link to the original DR-109.
