Will do and thank you!
The Kamm tail/desk wing seems to be an obvious mod to test. Will look into/read-up on Katz.

When you say 0.75 the length, do you mean 75% of a full teardrop shaped rear end (seems a bit long), or % of what, exactly?

The real mystery to me is how much should I taper the rear...given I'm starting with flat sides at about 70 inches width, what should my width be about, say, 3 feet back?

Or should I just try cutting off the back end taper entirely (straight down, forming a Kammback on the sides of the rear wheel) and just leave the rear wheel fairing sticking out of the back area with its further extended Kammback?
