A few more pics to provide the illusion of progress on this project:
Above: ghetto frame mostly completed. In this pic it's very firmly strapped to the car. Five... count 'em! 5 ratchet straps, 2 bungee cords (to be replaced by straps). Still some triangulation to be done.
I've extended a very light 1x1 frame out from the main frame to act as a skeleton. This one won't be a stressed skin structure like the Firefly tail.
Woo.
Starting on the "hip bustles".

I think it sticks out from the rearmost part of the bumper about 36 inches... I'll double-check tomorrow.
EDIT: nope, it's 31 inches.

working on the left hip
Correction, Sheepdog: it's 31 inches from the end of the bumper. 7 inches shorter than 3-wheeler's permanent tail.
I hope nobody's copying me, because I'm completely winging this one. We won't know how good my "aero eye" is until it's tuft tested & ABA'd.
Insert tab "A" into slot "B"...

*checks for tail*
I, too, am troubled by my lack of a tail.
I know I am buffeting my way through the atmosphere when I could be slicing through it. I could be saving at least 10% in fuel with a proper trailing edge. I could be passing through the dense fog with far less disturbance to the universe, yet still get where I am going quickly.
I may join thee in this quest for a proper termination of the vehicle body. |

Worked on the "hip/bustle" structure on the right side tonight. No pics (mirror image the pic from yesterday if you're having trouble visualizing it).
Ready to start putting the cardboard skin on it next.
Then... tuft testing! We'll see if it needs any tweaking before encapsulating it all in plastic.

Please do!
But... didn't you have a tail already? |

hips done
Main difference between the Firefly's tail and this one: hot glue gun! Highly recommended for CAD construction.
Both sides are done now. Top skin is next.

Metro, that is one of the best-looking prototypes that I have seen on this site! Is there any way that you could replace duct\100 MPH\hurricane tape with paper packaging tape? Are you planning on waterproofing that, or would you wait for the next version?
