I think we fall into a trap sometimes when quoting an "ideal angle" for a trailing surface. I think it depends on the other geometry around it. For instance, since yours has such a smooth organic taper rather than a sort of 2-D slice off an airfoil profile, I think the angle can be steeper- like how the EV1 backlight is steeper than our "ideal" aero template.

If you can make it adjustable and do tuft tests, that would be the best way to optimize that angle, moreso than us sitting around theorizing about it.
