I'm about settled down on dimensions again ( ).
This will have a frontal area of 53 sq. ft., and will follow the aft template faithfully till about the first 22 degree point. The sides will taper in a couple of small angle changes.
The rocker angle aft of the wheels needs to be a little steeper than ideal at 4.6 degrees.
The area at the back will be ~17 sq. ft.

What kind of Cd should I expect out of that, considering it will be faired smooth and tight to the tow rig and have above average fairness in general?
