This is the thing I raced there - It was influenced by the XGR cars as you can see...

The second photo was before the tape was removed from the canopy and the stickers applied. I ran out of time to fabricate a fairing for both the rear axle and the steering arms, but otherwise I think it is relatively aerodynamically clean.

Just took a few more photos of the car in my classroom (i'm a high school teacher) which show off the side profile a little better.

Wooly, do you have any pics with the shell off? I'm curious about the frame, steering, and brakes.

Took a while, but downloaded great! This is the only link that showed exactly what happened to me in a panic stop on my Pod (tadpole) velomobile- front hit the road, back flew up several feet. Great pictures!

Some 3-wheel car plans, some 4-wheel cars, some about aerodynamics, some electrics, ending with velomobiles. Like looking throughout time! Excellent for 3-wheel fanatics like me!
