Otto, The "box" was not what I was planning, but it was easy to achieve. I'm reevaluating the situation. Possibly incorporating the wheel skirt into the belly pan. The main reason for the "box", is because my sheets are only 2'x4'. Also, in between the wheels is more narrow. So if I was going to have it spread back out, I would think that it would be catching more wind?
Preferably, I would have it look like an upside down kamm, that is closed in. But trying to keep a 0 degree diffuser angle, it was easier to cut it off sharp which also helped to keep the coro in place to keep the ~0 degree angle.
I'm photoshop editing right now for a better design. Any help or suggestions on what I should do would be VERY
VERY appreciated!!
