It is not good at making compound curves, and generally only likes to be folded in one direction. I came up with the design below based on the Rumpler Tropfenwagen and the lakester salt flats racers, with a bit of influence by the LeMans velomobile. After that is a picture of the trike as it exists today. Open wheels are a necessity in order to fit it in and out of my doorway, and the body width is as narrow as possible while still providing clearance for the steering bars and without the wheels scrubbing. I estimate a frontal area of 0.6 m^2, but I am hoping to get a 0.25 Cd or below. Better shapes will be built after this one, but this will be the starting point.

The drawing of the body is done to scale. 1 square in the blue grid is 100 mm.
