This is a tapered, low drag airfoil, high aspect ratio wing. Let's see a similar video done on a Cub wing.Excellent video illustration of VGs.
Purty scary hearing 85 knots with flaps down tho.

On the spin - a good Cub ought not to spin with the ball in the center. I have found they will fly just fine fully stalled - they just shudder q bit.
Before VGs, I used up over 400 ft of the 5000 ft paved runway at Anoka County Airport. But now with VGs I consistently land under 250 ft. Yes, I feel much safer now and less concerned about overrunning into the bush. What a relief!
I think that VGs work but I'm too cheap to find out. And I'm EX so it would only be a couple hundred to find out. I've flown a couple Top Cubs with both std and extended wings and I'm still on the fence. I come over 60 ' trees and no flaps and can do 3 to 400' with out brakes so how are VGs going to help? And then theres the whole snow on the wing thing, how do I throw a blanket over the wing tip and saw the snow off of the top of the wing?

Also have a question - my templates have me putting two sets of VG's over the left wing landing light lens. Any suggestions as to how to handle? Install instructions state to move them spanwise along the wing, so trying to decide between going with one set right in the middle of the lens, or two sets straddling the lens on either side directly on the wing. Either way seems like it will look odd, so trying to get a feel for what others have done.
put them on lens where they belong... you are allowed to move them slightly if it gonna span a metal to lens area...
deleting one group would be very bad idea... the pairs are the far apart ones not the ones right next to each other.. so you'd kill one pair off or such...
Call me old-fashioned and stupid. But those things are for pussy's I ain't putin em on my pretty wings. Safety factor is just don't pull on the stick so hard. Remember if you want to go up pull back if you want to go down pull some more. So there.
