done, and tuft tested









Video coming later or tomorrow.

The good news:

1) The top side tufts look very happy, right to the tip of the tail.
2) We have flow re-attachment at about half of the way along in the pocket/notch behind the tail light (so, "trapped" turbulence bubble behind the light). I was a bit worried about how messy things might have turned out if the bubble wasn't completely captured.

The less good news: I think the side curvature is a bit too aggressive. There's quite a bit of turbulence in those last 3 tuft columns. They dance around quite a bit, sometimes off the surface, though they never point "in to" the flow, so we don't have reversal (worst case scenario).

I don't think it's so bad that it has to be rebuilt/modified. But I'll mull it over a bit.
