All respect to Mark Murphy, he's a great guy. Have you seen the little trailer he made from 2 BugE front fenders?
But that's a neighborhood vehicle. The Lithium Hawk is closer, but you'll notice he decided to upgrade to Mustang II front end components; and he's got that beautifully welded tube frame, all VINed and on the road, but hasn't started on the body.
Better analogs would be:
Arcimoto
Blackjack Zero
XR3
Elios
And this isn't going to turn into a build thread, I'm no closer than you to that. I was wanting to go off-topic in the Elios thread, and there are any number of people designing and (with varying degrees of success) building tadpoles
586 results for "reverse trike build"
So this is a place to collect ideas that might help others in their quest for tadpolehood. And a place to drop the links to some Autospeed articles on fabrication.
And a place to mention things like
Liquid Armor for making acrylic windows that you can live with.
Or maybe Photoshop a Messerschmitt done in Westergard style—black with a chopped Carson top, dragging it's tail and a little miniature '40 LaSalle grill with Appleton spotlights. That would be sweet.
