Dudley,
I don't quite understand how the fuel tank installation relates to
the dorsal fairing. Wasn't the fuel tank related to the "ass-heavy" CG
on the B-model (or did that also apply to the D)? The airflow off the
canopy makes a lot more sense to me.
I'm not trying to pick nits here, just curiousity has reared it's
ugly head. 8-)

I wouldn't disagree with this . Just mentioned it because it was a NA
engineer who threw it out there to us at one time.
In my opinion it was the canopy change that necessitated the need for
the dorsal extension. I remember questioning him at the time as well.
