@oeste858 Depends on who's theory you want to put your faith in. Maybe Wil was the only one that had real validation. I did the water hose test as GG requested(posted on my IG story). What I saw, depending on the stream of water direction, is that at times the canard will direct water to the main. Not scientific but I was able to get water to direct to the main. I know GG doesn't believe it does as described, but my own experiment lead me to an open mind. so I think it might be more than just increased fin area.
