The rear hinge is the earlier iteration. The current one is binged on the side - and it has a wiper that pivots at the leading edge of the canopy. I've inquired about dimensions and specs and 3D model, etc. They don't intend to produce it (they are volunteers at a university in Adelaide?)but they do have a couple of construction articles that I linked to on the
Team Trev thread and they hope people will built it or vehicles like it.
I think it could be improved aerodynamically (in addition to skirting the front wheels): the sides need to slightly convex, and the shoulder needs to angle down rather than up.
