Hello All..
Have had much success with these on Yaks and other airshow planes. 1-15% on
the low end is huge. I put some on my Glasair at 10% of cord but really did
not see much difference in the stall speed. Has anyone else put Vortex
generators on and what is your experience please?
Thanks Much,
Bob

Evening Dick,
I bought a Glasair 1 TD.early model with low hours. I have put some yarn on
the wing at intervals. Unfortunately poorly filmed so I need to do it again.
What seemed odd and I am not drawing conclusions here yet as I did not get
the audio with it to give perspective, but it appeared that the wing root to
3' was stalling long before the rest of the wing.
Just looking for some owners experience.or suggestions. Thanks!
Bob

Black sciencecompletely! Would love to see the drawing if you
are willing to share? My first question on watching the poor video
was this the strake causing this? My understanding is that the
strake was added because of the docile stall characteristics. It
appeared much different than the rest of the wing and now wondering if I
should attempt to put them on different chord lengths. As long as both
wings are the samethoughts?

Unsure if anyone has tried it yet.
