  • The lip: better, worse or an evolution of the Gurney flap?

  • The green arrow: Was that a step or a slot beneath the arrowhead?
1. I don't understand the reference to a Gurney flap. A Gurney flap is used on a wing. This is not a wing, so I cannot see how anything on this spoiler can be referred to in that context. Re the lip, 'better' or 'worse' in what regard? Lift? Drag?

2. The longitudinal strakes, I suggest, perform the function I ascribed to them in the video. I don't see the longitudinal filler strips doing much to cause separation.

3. Step not slot. And such a small step it would be of no consequence I would think.
