Did some water and tuft testing. Is the aero good?

So does this look like it has the right flow going on?

It seems pretty good. There seems to be more turbulence coming from the cab/cap gap (tongue twister) on the sides.

On another note, you did some nice work on the cap.

Looks good to me.I never saw any counterflow.It's okay if the tufts on the sides point up a bit,the air is bleeding towards the lower pressure on top.That's normal.Kamm had it.
I don't see evidence of longitudinal vortices either.I think you're pretty much good to go.
Nice
wind tunnel work! Thanks a lot!
