The problem with the winglets is they'll increase effective dihedral on the airplane when upright. I think it's interesting to see the developments, but a lot of this DOES feel very much like trial and error as opposed to engineering a solution to a problem.

Exactly!!
the marketing dept is making design decisions again...
there is no way those winglets are gonna make that plane fly more neutral or symmetric (Upright vs inverted)
I expect the yaw coupling is significantly impacted in a negative manner in particular....
I expect there will be the Kool Aid drinkers that will go on and on about how great they make the plane...
hogwash....
winglets are for making a plane (specifically a wing) more efficient if there is a span limitation....
and the more effective a winglet is.. the more damaging it will be in the off-design condition...
all they need are little embedded LED's ......Buick Ventiports
