No, just the width of the boundary layer, hence the folds. Messing around with the cp was reasonably well understood.

By BAT9 they were toned down quite a bit. Maybe they weren't?



Or maybe they didn't go far enough.

I don't think those BATs are in chronological order. In any event, they were not making fins for the usual reasons, or they would not have become curled.
The windmobile is another way to use fins for something other than stability, and I think it has considerable potential as a way to reduce average drag in the real world, even if pure wind power is seldom close to adequate. I saw the John Paul Mitchell Systems wind & pedal hybrid get hit by a gust, and the acceleration was startling.

There exists a BAT 11.

Indeed. Well, the aeronautic themes were very popular by then, with the jets taking over the commercial aviation... And it does resemble an F-5 with the afterburner lit

I have never seen any vehicle with a bodywork dedicated for pulling a glider. At an aeroclub I went once, a Chevette with its top chopped off was used for this purpose.
