And now I have tested on a day with gusting 25-30 km/h crosswinds. And, in those conditions, the Edgarwits do absolutely nothing to reduce drag. The throttle-stop speeds with and without the aerofoils is identical.
So that behoves the question: do
any air curtains work in gusty crosswinds? I have never seen any published research on this, so I have asked an expert I know. It will be interesting to see what he says.
