Correct me if I'm wrong, but isn't this the same man who the "Kamm Effect"
is named after? I think he said something to the effect that if a vehicle's
rear end bodywork can't be extended back at a sub- critical angle (7
degrees, I take it) then it's better to cut it off abruptly. There were lots
of cars running a Kamm rear body shape back a few years ago. The Cobra
Daytona Coupe is one example, I think. Has anyone tried this in LSR? Any
success?

Hello Pork Pie,

Thanks for the correction.  My aero "knowledge" does come from aviation and,
in fact, I've quoted 7 degrees to this list.  I stand corrected.

Dale C.

Why - thet got rear ends with a 7 degrees tapered shape.

But this is wrong. For the car aerodynamic you need 6 degrees.
A German guy, named Willibald Kamm, investigate this more than 60 years ago.
Kamm was Professor for aerodynamic in Stuttgart, where they done also the 
aerodynamic for the NSU Dolphine and NSU Baum'sche Liegestuhl (Flying
chair).

It may be surprise, that there is a different between an aeroplane (7)and a
car 
(6).
